A function relating these variables is D(x) = 10 + 2x,

D(9) = 28, meaning after 9 hours of snowfall,

What is an independent variable?

An independent variable is a variable that is manipulated or controlled by the researcher in an experiment to observe its effect on the dependent variable. It is the variable that is changed deliberately to see how it affects the outcome of the experiment.

The independent variable, x, represents the number of hours since snow began falling,

and the dependent variable is the total amount of snow on Jace's lawn because the amount of snow depends on the number of hours since it began to snow.

A function relating these variables is D(x) = 10 + 2x, where D(x) is the total amount of snow on Jace's lawn in inches after x hours of snowfall.

So, D(9) = 28, meaning after 9 hours of snowfall, Jace will have a total of 28 inches of snow on his lawn.

Assume that a box contains 3 different of cowpea seeds, with three seeds weighing each, Il seeds weighing 0.81g each, 7 seeds weighing 12g each. What is the probability that a seed selected at random will weigh 0.8​

Answers

The problem states that there are 3 different types of cowpea seeds in the box, but it does not provide any information about the weight of each type of seed. Instead, the problem provides the weight of each individual seed for two of the three types. Therefore, we cannot accurately calculate the probability of selecting a seed that weighs exactly 0.8g from the box using the information provided.

If we assume that the problem meant to say that there are three seeds of each type, and that the weight of the third type is also 0.81g per seed, then we can calculate the probability of selecting a seed that weighs exactly 0.8g as follows:

Total weight of all seeds in the box = (3 x 0.81g) + (3 x 12g) + (3 x 0.8g) = 3.15g + 36g + 2.4g = 41.55g

Probability of selecting a seed that weighs exactly 0.8g = (3 x 0.8g) / 41.55g = 0.0727 or approximately 7.27%

However, since the problem does not provide clear and complete information, it is best to clarify the details or assume that something is missing before attempting to solve it.

An employee does not earn sales commission for the first 1000 of sales but earns 15% sales commission on all sales made thereafter. The employees daily sales were as follows this week Monday 800 Tuesday 600 Wednesday 1300 Thursday 800 and Friday 800 how much sales commission did the employee earn this week

Answers

Answer:

$525

Step-by-step explanation:

To calculate the sales commission for this employee, we need to first calculate the total sales made by the employee for the week. The employee made sales of 800 on Monday, 600 on Tuesday, 1300 on Wednesday, 800 on Thursday and 800 on Friday. The total sales made by the employee for the week is:

800 + 600 + 1300 + 800 + 800 = 4500

Since the employee does not earn sales commission for the first $1000 of sales but earns a 15% sales commission on all sales made thereafter, we need to calculate the commission earned on sales above $1000.

The total sales above $1000 is:

4500 - 1000 = 3500

The commission earned on sales above $1000 is:

3500 x 15% =$525

Therefore, the employee earned a sales commission of $525 this week.

Answers

Answer:

60 seconds

Step-by-step explanation:

Let's start by finding how much more water needs to be added to the solution to reach a total of 10 ml of water:

10 ml - 5.8 ml = 4.2 ml

Now we can use the formula:

time = amount of water added / rate of addition

to calculate the time it will take to add 4.2 ml of water at a rate of 0.07 ml/s:

time = 4.2 ml / 0.07 ml/s

time = 60 seconds (rounded to the nearest second)

Therefore, it will take 60 seconds to add enough water to the solution to make a total of 10 ml of water.

Find the equation of the exponential function represented by the table below:

Answers

The equation of exponential function of following table is represented by the table below is y = A(Bˣ).

Give brief account on exponential function.

An exponential function is a mathematical function denoted by f(x) = eˣ (where the argument x is written as an exponent). Unless otherwise stated, the term usually refers to positive-valued functions of real variables, but can be extended to complex numbers and generalized to other mathematical objects such as matrices and Lie algebras. Although the exponential function arose from the notion of exponentiation (iterative multiplication), its modern definition (which has several equivalent characterizations) allows it to be extended exactly to any real argument, including irrational numbers. Its ubiquitous appearance in pure and applied mathematics has led mathematician Walter Rudin to believe that the exponential function is "the most important function in mathematics."

To find the equation of exponential form:

For case 1,

Exponential form: y = A(Bˣ)

y = 0.1, x = 0

[tex]0.1 = A(B^{0})[/tex]

0.1 = A(1)

A = 0.1

For case 2,

Exponential form: y = A(Bˣ)

y = 0.05, x = 1

[tex]0.05 = 0.1(B^{1})[/tex]

B = 0.5

For case 3,

y = 0.025, x = 2

[tex]A = 0.1(B^{2})[/tex]

[tex]0.025 = 0.1(0.5^{2})[/tex]

0.025 = 0.025

For case 4,

y = 0.0125, x = 3

0.0125 = 0.1(0.5³)

0.0125 = 0.1(0.125)

0.0125 = 0.0125

We calculated the value of A and B, and proved it in case 3 and case 4.

(1.3.1) – Plotting Points On A Coordinate Plane

The coordinate plane was developed centuries ago and refined by the French mathematician René Descartes. In his honor, the system is sometimes called the Cartesian coordinate system. The coordinate plane can be used to plot points and graph lines. This system allows us to describe algebraic relationships in a visual sense, and also helps us create and interpret algebraic concepts.

You have likely used a coordinate plane before. The coordinate plane consists of a horizontal axis and a vertical axis, number lines that intersect at right angles. (They are perpendicular to each other.)

A graph with an x-axis running horizontally and a y-axis running vertically. The location where these axes cross is labeled the origin, and is the point zero, zero. The axes also divide the graph into four equal quadrants. The top right area is quadrant one. The top left area is quadrant two. The bottom left area is quadrant three. The bottom right area is quadrant four.
The horizontal axis in the coordinate plane is called the x-axis. The vertical axis is called the y-axis. The point at which the two axes intersect is called the origin. The origin is at 0 on the x-axis and 0 on the y-axis.

Locations on the coordinate plane are described as ordered pairs. An ordered pair tells you the location of a point by relating the point’s location along the x-axis (the first value of the ordered pair) and along the y-axis (the second value of the ordered pair).

In an ordered pair, such as (x, y), the first value is called the x-coordinate and the second value is the y-coordinate. Note that the x-coordinate is listed before the y-coordinate. Since the origin has an x-coordinate of 0 and a y-coordinate of 0, its ordered pair is written (0, 0).

Use a system of two equations in two​ variables, and​ d, to write a formula for the general term​ (the nth​ term) of the arithmetic sequence whose fourth ​term, a4​, is 10 and whose sixth ​term, a6​, is 18.

Answers

The formula for the nth term of the arithmetic sequence is an = 4n + 2

How to write a formula for the general term​ (the nth​ term) of the arithmetic sequence?

Let d be the common difference of the arithmetic sequence, and let a1 be the first term. Then we have:

a4 = a1 + 3d = 10

a6 = a1 + 5d = 18

We can solve this system of equations to find a1 and d. Subtracting the first equation from the second, we get:

2d = 8

d = 4

Substituting this into either of the original equations, we get:

a1 + 12 = 18

a1 = 6.

So the arithmetic sequence is:

6, 10, 14, 18, ...

To find the nth term of this sequence, we can use the formula:

an = a1 + (n - 1)d

Substituting in the values of a1 and d, we get:

an = 6 + 4(n - 1)

Simplifying, we get:

an = 4n + 2

Therefore, the formula for the nth term of the arithmetic sequence whose fourth term is 10 and sixth term is 18 is:

an = 4n + 2

Find the error. A student was finding the measure angle 5 in the figure below. She concluded that m angle 5=86

Answers

The answer is Option 2: The measure of angle 5 is corresponding to angle 1. Angle 1 is supplementary to 86. So, measure angle 1 = 94. Since corresponding angles are equal angle 5 = 94.

What is a supplementary angle?

An angle that, when combined with another angle, creates a straight angle (measuring 180 degrees), is known as a supplementary angle. In other words, if the sum of the measurements of two angles is 180 degrees, they are supplementary. Contrarily, a complimentary angle is one that, when combined with another angle, creates a right angle (which has a 90-degree angle). In other words, if the sum of the measurements of two angles is 90 degrees, they are complimentary. A straight angle and a right angle are not the same thing, hence it is crucial to understand that one angle cannot be both supplementary and complimentary at the same time.

From the given figure we see that the measure of angle 5 is corresponding to angle 1. Angle 1 is supplementary to 86. So, measure angle 1 = 94. Since corresponding angles are equal angle 5 = 94.

Show that the angle bisector of an equilateral triangle is perpendicular to the base​

Answers

To show that the angle bisector of an equilateral triangle is perpendicular to the base​, we can assume an equilateral triangle with sides ABC. Next, we can get an angle bisector in the middle represented by BD which becomes perpendicular to the base BC.  

How to prove that the angle bisector is perpendicular to base

After getting the angle bisector, we would see that the line segment BD, divides angle BAC into two equal angles, each measuring 30 degrees. Now, we can draw a perpendicular line from point D to the base BC.

We could also draw a line E, which is the perpendicular line that intersects the base BC. We want to show that BD is perpendicular to BC, which means we need to show that angle BDE is a right angle.

Since the sum of angles BDA and ADE is 90 degrees (they form a right angle), and the sum of angles BAD, ABD, and BDA is 180 degrees, it follows that angle BDE must be a right angle.

Therefore, we have shown that the angle bisector of an equilateral triangle is perpendicular to the base.

Therefore, the expected value of the event P(2k) for 2 ≤ k ≤ 6, given the event E, is 96/1 or simply 96.

What is probability?

Probability theory is widely used in many fields, including mathematics, statistics, physics, engineering, economics, and social sciences. It provides a framework for analyzing and understanding uncertain events and making predictions based on available information. Probability theory is also used in decision-making, risk management, and game theory, among other applications.

Here,

We can start by calculating the probability of each event in the sample space:

P(1) = 1/32

P(4) = 1/8

P(8) = 1/4

P(16) = 1/2

P(32) = 1

P(64) = 1

Next, we can calculate the probability of the event E by summing the probabilities of the individual outcomes in E:

P(E) = P(1) + P(8) + P(32) + P(64)

= 1/32 + 1/4 + 1 + 1

= 33/32

Now, we can calculate the expected value of the event P(2k) for 2 ≤ k ≤ 6:

E[P(2k)] = Σ[2 ≤ k ≤ 6] P(2k) * ΘS(2k)

= P(4)*ΘS(4) + P(8)*ΘS(8) + P(16)*ΘS(16) + P(32)*ΘS(32) + P(64)*ΘS(64)

= (1/8)*4 + (1/4)*8 + (1/2)*16 + (1)*32 + (1)*64

= 4/8 + 8/4 + 16/2 + 32 + 64

= 1/2 + 2 + 8 + 32 + 64

= 106.5

Therefore, the expected value of the event P(2k) for 2 ≤ k ≤ 6, given the event E, is 106.5. However, since the event E has a probability greater than 1, this result does not make sense. So, we need to normalize the probabilities of the events by dividing them by P(E) to obtain the correct expected value:

P'(1) = P(1)/P(E) = (1/32)/(33/32) = 1/33

P'(8) = P(8)/P(E) = (1/4)/(33/32) = 8/33

P'(32) = P(32)/P(E) = 1/(33/32) = 32/33

P'(64) = P(64)/P(E) = 1/(33/32) = 32/33

Now, we can calculate the normalized expected value:

E[P(2k)] = Σ[2 ≤ k ≤ 6] P'(2k) * ΘS(2k)

= P'(8)*ΘS(8) + P'(32)*ΘS(32) + P'(64)*ΘS(64)

=(8/33)*8 + (32/33)*32 + (32/33)*64

The solution to this system is (-2, 1):

To solve the system of linear equations, we can use the method of substitution or elimination. Here, we will use the method of substitution.

From the second equation, we can solve for y in terms of x:

3x + 2y = -6
2y = -3x - 6
y = (-3/2)x - 3

Now we can substitute this expression for y into the first equation:

4x - 3y = -8
4x - 3((-3/2)x - 3) = -8

Simplifying and solving for x, we get:

4x + (9/2)x = 1
(17/2)x = 1
x = -2/17

Now we can substitute this value of x into the expression we found for y:

y = (-3/2)x - 3
y = (-3/2)(-2/17) - 3
y = 1/17 - 3
y = -50/17

a. 110° positive angles:
negative angles:

b. 165° positive angles:

c. -10° positive angles:

Answers

Answer:

a. 110°

Positive coterminal angles: 110° + 360° = 470°, 110° + 2(360°) = 830°

Negative coterminal angles: 110° - 360° = -250°, 110° - 2(360°) = -610°

b. 165°

Positive coterminal angles: 165° + 360° = 525°, 165° + 2(360°) = 885°

Negative coterminal angles: 165° - 360° = -195°, 165° - 2(360°) = -555°

c. -10°

Positive coterminal angles: -10° + 360° = 350°, -10° + 2(360°) = 710°

Negative coterminal angles: -10° - 360° = -370°, -10° - 2(360°) = -730°

Step-by-step explanation:

When an angle is in the standard position, it means that the initial side of the angle is the positive x-axis, and the terminal side of the angle is located in one of the four quadrants of the coordinate plane.

To find coterminal angles, we need to add or subtract multiples of 360 degrees to the given angle while keeping the terminal side in the same position. This is because a full rotation around the origin in the coordinate plane is 360 degrees.

For positive coterminal angles, we add multiples of 360 degrees to the given angle. In the case of 110 degrees, we can add 360 degrees once or twice to get 470 degrees or 830 degrees, respectively.

For negative coterminal angles, we subtract multiples of 360 degrees from the given angle. In the case of -10 degrees, we can subtract 360 degrees once or twice to get -370 degrees or -730 degrees, respectively.

It's important to note that there are infinitely many coterminal angles for any given angle, but we usually restrict our answers to the smallest positive and negative angles that differ from the given angle by a multiple of 360 degrees.

Use the form |x – b | ≤ c or |x – b | ≥ c to write an absolute value inequality that has the solution set x ≤ –9 or x ≥ –5
what is the answer?

Answers

The inequality |x + 7| ≥ 2 has the solution set x ≤ –9 or x ≥ –5, as required.

Writing an absolute value inequality

We can write an absolute value inequality with the given solution set as follows:

|x + 7| ≥ 2

Here's how we arrived at this inequality:

First, we find the midpoint of the given solution set:

midpoint = (-9 + (-5)) / 2 = -7

Next, we find the distance from the midpoint to each endpoint of the solution set:

distance to -9 = |-7 - (-9)| = 2

distance to -5 = |-7 - (-5)| = 2

The maximum distance is 2, so we use c = 2 in the inequality.

Since the midpoint is to the left of both endpoints, we use the form |x - b| ≥ c.

Plugging in b = -7 and c = 2, we get:

|x + 7| ≥ 2

This inequality has the solution set x ≤ –9 or x ≥ –5, as required.

C(n, k-1) + nC(n, k) = C(n + 1, k)​

Answers

The equation C(n, k-1) + nC(n, k) = C(n + 1, k) is known as the Pascal's rule or Pascal's identity, which relates the binomial coefficients C(n, k) and C(n + 1, k).

To understand how the equation works, we can break down each term:

- C(n, k-1) represents the number of ways to choose k-1 objects from a set of n objects.
- nC(n, k) represents the number of ways to choose k objects from a set of n objects, multiplied by the number of ways to choose one additional object from the remaining n-k objects.
- C(n + 1, k) represents the number of ways to choose k objects from a set of n+1 objects.

By combining these terms, we can see that the left-hand side of the equation represents the total number of ways to choose k objects from n+1 objects. This is equivalent to the right-hand side of the equation, which also represents the number of ways to choose k objects from n+1 objects.

Therefore, Pascal's identity can be used to simplify calculations involving binomial coefficients, making it a powerful tool in combinatorics and probability theory.

Answers

Answer:

∠ A = 76°

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

9x - 5 - 5 + 6x + 55 = 180

15x + 45 = 180 ( subtract 45 from both sides )

15x = 135 ( divide both sides by 15 )

x = 9

Then

∠ A = 9x - 5 = 9(9) - 5 = 81 - 5 = 76°

Start at -2 on the number line and move 7 to the left.

Describe Number line?

A number line is a visual representation of the real numbers as a straight line. It is a useful tool for understanding and comparing numbers, as well as for performing operations on them.

The number line is typically drawn horizontally, with zero in the center and positive numbers to the right of zero and negative numbers to the left of zero. The distance between any two points on the number line represents the difference between the corresponding numbers.

The number line is also commonly used for representing fractions, decimals, and irrational numbers. For example, fractions can be represented as points on the number line by dividing the line into equal segments, with each segment representing one unit fraction. Decimals can be represented as points on the number line by marking off the appropriate place value.

In addition to basic arithmetic operations such as addition, subtraction, multiplication, and division, the number line can be used to perform more advanced operations such as finding absolute value, calculating distance between two points, and solving linear equations.

Overall, the number line is a powerful visual tool that helps to deepen our understanding of the real numbers and their relationships.

Answers

Answer:

red: y = 5green: y = -2x +1blue: y = 2x -1yellow: y = -1/2x -1

Step-by-step explanation:

You want the equations for the lines shown on the graph.

Slope-intercept form

The slope-intercept form of the equation for a line is ...

  y = mx + b

where m is the slope, and b is the y-intercept.

Slope

The slope of a line is the ratio of its "rise" to its "run". The rise and run are the vertical distance and horizontal distance between two points, respectively. We usually want to choose points that are where the line crosses grid intersections, as this gives the most exact value for the slope.

Red line: There is no rise for any value of run. The slope is ...

  m = rise/run = 0/1 = 0

Green line: The green line crosses the y-axis at y = 1, and crosses the next grid intersection to the right at (1, -1). The rise between those points is -2 (2 grid squares down), and the run is 1 (1 grid square to the right). The slope is ...

  m = -2/1 = -2

Blue line: The blue line crosses the y-axis at y = -1, and crosses the next grid intersection to the right at (1, 1). The rise between those points is +2 (2 grid squares up), and the run is 1 (1 grid square to the right). The slope is ...

  m = 2/1 = 2

Yellow line: The yellow line crosses the y-axis at y = -1, and crosses the next grid intersection to the right at (2, -2). The rise between those points is -1 (1 grid square down), and the run is 2 (2 grid squares to the right). The slope is ...

  m = -1/2

Y-Intercept.

The y-intercept is the value of y where the line crosses the y-axis. In the slope-intercept form equation (y=mx+b), this is the value of 'b'. In the previous section, we used those crossings as one of the grid intersections for finding the slope. They are ...

Red: +5Green: +1Blue: -1Yellow: -1

Equations

Using the slope and y-intercept for each line, we can now write the equations:

Red: y = 0x +5   ⇒   y = 5Green: y = -2x +1Blue: y = 2x -1Yellow: y = -1/2x -1

__

Additional comment

The slope-intercept form of the equation is not the only possible way to write an equation for a line. There are more than half a dozen other ways an equation for a line can be written. Each will have its use.

Other forms include ...

  ax +by = c . . . . . . . standard form

  ax +by -c = 0 . . . . . general form

  x/a +y/b = 1 . . . . . . . intercept form

  y -k = m(x -h) . . . . . point-slope form

Intercept forms don't work well when one of the intercepts is missing. For the red line, the x-intercept is missing. Essentially, the x-terms disappear from the standard, general, and intercept form equations. In the point-slope form, the equation of the red line is y-5=0, since the slope is 0.

An angle measures 6.6° more than the measure of its complementary angle. What is the measure of each angle?

Answers

Answer:

Angle 1 = 51.6°

Angle 2 = 38.4°

Step-by-step explanation:

All complimentary angles add up to 90°.

If two complimentary angles were congruent then their measures would both be 45°.

Since one angle's measure is 6.6° more than the other's measure, it's measure is 6.6° more than 45°

Vice versa for the second angle, its measure will be 6.6° less than 45°
