Using the graphing function on your calculator, find the solution to the system of equations shown below. 4y + 12x = 10 2y - 6x = -8 A. No solution B. More than 1 solution C. x = 13/12, y = -3/4 D. x = -6, y = 2

Answers

Answer 1

Therefore, the solution to the system of equations is: x = 13/12, y = -3/4 that is option C.

What is equation?

In mathematics, an equation is a statement that asserts the equality of two expressions, separated by an equals sign (=). The expressions on either side of the equals sign are referred to as the left-hand side (LHS) and the right-hand side (RHS) of the equation. Equations are used to describe relationships between variables and to solve problems.

Here,

To solve the system of equations:

4y + 12x = 10 ...(1)

2y - 6x = -8 ...(2)

We can use the method of elimination or substitution.

Method of elimination:

We can eliminate x by multiplying equation (2) by 2 and adding it to equation (1) to obtain:

4y + 12x = 10

(4y - 12x = -16)

8y = -6

Dividing both sides by 8, we get:

y = -6/8

y = -3/4

Substituting this value of y in equation (1), we get:

4(-3/4) + 12x = 10

Simplifying and solving for x, we get:

-3 + 12x = 10

12x = 13

x = 13/12

So the answer is C. x = 13/12, y = -3/4.

What is a scatter-plot?

The graphs, scatter plots, or scatter charts show the relationship between two variables in a data set that has been analysed.  Both a two-dimensional plane and the Cartesian-system are used to represent the data points. Observing and illuminating correlations between two numerical variables is the main purpose of scatter plots. When the data are viewed as a whole, the dots in a scatter plot show patterns in addition to the values of the individual data points. The Y-axis is used to plot the dependent variable, while the X-axis is used to represent the independent variable or attribute. Using a scatter plot, you may see what happens to one variable when another variable is altered. To determine whether the two variables are connected, a scatter plot is utilised.

The scatter plot shows the dog weights & their heights surveyed.

Data represented on X-axis(independent variable) : heights of dogs

Data represented on Y-axis(dependent variable) : weights of dogs

Answers

The area of the floor of the igloo is 842.9 m²

We know that the formula for the volume of hemisphere is given by,

V = (2/3) × π × r³

where r is the radius of the hemisphere

Here, a hemisphere igloo has a volume of about 9,202.8 m³

Using above formula of the volume of hemisphere,

V = (2/3) × π × r³

9202.8 = (2/3) × π × r³

r³ = 9202.8 × (3/2π)

r³ = 4394.01

r = 16.38 m

We know that the area of the floor of the igloo is equivalent to the area of circle, as the base of hemisphere is a circle.

So, the area of the floor of the igloo would be,

Answers

The requried equation of the circle with center (-3,0) passing through (-3,3/2) is 4(x + 3)² + 4y² = 9

We are given that the center of the circle is (-3,0) and it passes through (-3, 3/2). Since the x-coordinate of both points is the same, we know that the center lies on a vertical line passing through (-3, 3/2). Therefore, the distance between the center and the point (-3, 3/2) is the radius of the circle.

The radius is found using the distance formula:

r = √[(x₂ - x₁)² + (y₂ - ₁)²]

r = √[(-3 - (-3))² + (0 - 3/2)²] = √[9/4] = 3/2

So, the equation of the circle in standard form is:

(x - (-3))² + (y - 0)² = (3/2)²

(x + 3)² + y² = 9/4

The measure of angle ABD (which is the same as angle CBD) is 45 degrees.

Is a parallelogram in the figure of a CBD? Why?

The quadrilateral's opposing sides are equal. Triangles ABC and ABCD have equal angles on either side of their equal sides. In the quadrilateral ACBD, the opposing angles are also equal. A parallelogram is formed by ACBD.

We can use the fact that the total of the angles of a triangle is always 180 degrees to determine the measure of angle CBD. As a result, we have:

Angle ABD + Angle CBD + Angle BCD = 180 degrees

Substituting the given angle measures, we get:

Angle ABD + Angle CBD + 90 degrees = 180 degrees

Simplifying, we get:

Angle ABD + Angle CBD = 90 degrees

But we know that Angle ABD = Angle CBD, so we can substitute:

2 x Angle ABD = 90 degrees

Dividing both sides by 2, we get:

Angle ABD = 45 degrees

Each checking account deposit was half the amount of each savings account deposit, and the total of all deposits for the year was $15,200. Which system of equations can be used to determine the values of x and y?

Answers

Kalani deposited $200 into her checking account every week and $400 into her savings account every month.

What is system of equation?

A group of equations that must be solved simultaneously is referred to as a system of equations. Typically, a system of equations involves multiple variables, and the goal is to find the values of those variables that satisfy all of the equations in the system.

According to question:

Let's start by using the given information to write equations for the total amount deposited in each account over the course of the year.

For the checking account, Kalani deposited x dollars every week for 52 weeks, so the total amount deposited for the year is:

52x

For the savings account, Kalani deposited y dollars every month for 12 months, so the total amount deposited for the year is:

12y

We are also told that each checking account deposit was half the amount of each savings account deposit, so we can write:

x = (1/2)y

Finally, we are given that the total of all deposits for the year was $15,200, so we can write:

52x + 12y = 15200

A system of two equations with two variables is now available:

x = (1/2)y

52x + 12y = 15200

We can solve this system to determine the values of x and y. The result of putting the first equation into the second equation is:

52(1/2)y + 12y = 15200

Simplifying:

26y + 12y = 15200

38y = 15200

y = 400

Substituting y = 400 into the first equation, we get:

x = (1/2)y = (1/2)(400) = 200

Therefore, Kalani deposited $200 into her checking account every week and $400 into her savings account every month.

For given data, Carrie threw the ball highest = 35ft and ball stayed in the air longest = 3s for Carrie as well.

How does projectile motion work?

Any object that is fired into the air and travels in that direction is referred to as a projectile. Gravitation, however, is another force that an object experiences after the first force that pushes it.

Three distinct individuals, Alberto, Ben, and Carrie, each toss a ball straight up into the air.

Following equation may be used to explain Alberto's throw.

[tex]H = -16t^2 + 32t + 4[/tex]

Now , to find the maximum height, we solve for first derivative w.r.t.t,

[tex]-32t + 32 = 0[/tex]

[tex]32t=32\\t = 1s[/tex]

Using t=1, we can find maximum height as

[tex]H =-16(1)^2 + 32(1) + 4\\\\H=(-16)+32+4[/tex]

[tex]H= 20[/tex] ft

Thus, when Alberto threw ball, maximum height attained= 20 ft and total time duration ball was in air = 1s.

From the given table( refer to attached image),

Jack and Carlie each deposit $17,250 into accounts that earn 6% interest for 6.5 years. Jack's account earns annual simple interest and Carlie's account earns annual compound interest. Who will earn more interest after 6.5 years, and how much more interest will they earn?

Answers

Okay, let's calculate the interest earned by each person over 6.5 years.

Jack's account earns annual simple interest, so the formula for simple interest is:

I = P * r * t

where:
I = interest earned
P = principal (initial amount deposited)
r = annual interest rate
t = time in years

Using the given values, we get:

I = 17,250 * 0.06 * 6.5
I = $6,332.50

Therefore, Jack will earn $6,332.50 in simple interest over 6.5 years.

Carlie's account earns annual compound interest, so the formula for compound interest is:

A = P * (1 + r/n)^(n*t)

where:
A = amount after time t
P = principal (initial amount deposited)
r = annual interest rate
n = number of times interest is compounded per year
t = time in years

Using the given values, we get:

A = 17,250 * (1 + 0.06/1)^(1*6.5)
A = $27,943.93

The amount after 6.5 years is $27,943.93, which includes the principal and compound interest earned. To find the amount of interest earned, we subtract the principal:

Interest earned = A - P = $27,943.93 - $17,250 = $10,693.93

Therefore, Carlie will earn $10,693.93 in compound interest over 6.5 years.

So, Carlie will earn more interest than Jack, and the difference between the interest earned is:

$10,693.93 - $6,332.50 = $4,361.43

Therefore, Carlie will earn $4,361.43 more interest than Jack over 6.5 years.

Find the exact value of tan P in simplest radical form. √85 2 N √89​

Answers

Answer:

We can start by using the tangent formula:

tan(P) = sin(P) / cos(P)

We are not given the values of sin(P) and cos(P) directly, but we can use the Pythagorean identity to relate them:

sin^2(P) + cos^2(P) = 1

We can rearrange this expression to solve for sin(P) in terms of cos(P):

sin^2(P) = 1 - cos^2(P)

sin(P) = ±√(1 - cos^2(P))

Now we can substitute this expression into the tangent formula:

tan(P) = ±√(1 - cos^2(P)) / cos(P)

Substituting the given values and simplifying:

tan(P) = ±√(1 - (2/√85)^2) / (1/√89)

tan(P) = ±√(1 - 4/85) * √89

tan(P) = ±√(81/85) * √89 / 1

We want to express tan P in simplest radical form, so we can simplify the square root by factoring out the greatest perfect square factor of the numerator:

tan(P) = ±(√9/√85) * (√89/1)

tan(P) = ±(3/√85) * (√89/1)

Therefore, the exact value of tan P in simplest radical form is ±(3/√85) * (√89/1).

Let's look at the given statement. It states that [tex]T(c1v1 + c2v2) = c1T(v1) + c2T(v2)[/tex] for all v1 and v2 in the domain of T and for all scalars c1 and c2.

This is equivalent to saying that T is both additive and homogeneous, since we can rewrite the statement as [tex]T(c1v1 + c2v2) = T(c1v1) + T(c2v2) = c1T(v1) + c2T(v2).[/tex]
A transformation satisfies the given statement, it is both additive and homogeneous, and hence it is linear.

On the other hand, if a transformation is linear, it must satisfy the given statement by definition.

The statement "A transformation T is linear if and only if [tex]T(c1v1 + c2v2) = c1T(v1) + c2T(v2[/tex]) for all v1 and v2 in the domain of T and for all scalars c1 and c2" is true.

In which direction will the ionic paste allow the electrons to flow within a battery? O negative side to negative side negative side to positive side positive side to negative side positive side to positive side​

Answers

Answer:

The electrons in the battery will flow from the negative electrode (anode) to the positive electrode (cathode) through an external circuit, driven by the potential difference created by the ionic paste.

Step-by-step explanation:

In a battery, the ionic paste, which is usually an electrolyte solution, allows the flow of ions between the electrodes of the battery. This flow of ions creates a potential difference between the two electrodes, which in turn creates an electric field.

The electrons in the battery will flow from the negative electrode (anode) to the positive electrode (cathode) through an external circuit, driven by the potential difference created by the ionic paste. As the electrons move through the external circuit, they can be used to power a device or do useful work.

It is important to note that the flow of electrons occurs only in the external circuit, while the flow of ions occurs only within the battery itself, through the ionic paste. The flow of electrons and ions is connected but separate processes that work together to generate electrical energy in a battery.

Using probability, we can find the following:

a. In the figure.

b. The probability that the first set is green is = 0.8

c. Probability that the second set is green is = 0.06

d. The probability that both the sets are green is = 0.48

e. The probability that at least one set is green is = 0.86

Define probability?

The likelihood that an event will occur is described by probability. There are many circumstances in real life where we may need to foresee how something will turn out. We might be able to predict the outcome of an event or we might not. At this point, we say, "There is a chance that the event will happen or not."

Here in the question,

b.

The probability that the first set is green is:

P = 1 - 0.2

= 0.8

c.

Now the first set is given as not green.

Probability that the second set is green is:

p = 0.2 × 0.3

= 0.06

d.

Now probability that both the sets are green is:

P = 0.8 × 0.6

= 0.48

e.

When both the sets are not green, probability is:

0.2 × 0.7

= 0.14

So, probability that at least one set is green is:

P = 1- 0.14

= 0.86

In a sample of 20 items, you found six defective. In constructing a confidence interval for the proportion of defectives, you should use: the plus four method. the large-sample interval. neither of these two methods.

Answers

To construct a confidence interval for the proportion of defectives, we should use the plus four method.

Since the sample size is 20, which is not very large, the large-sample interval is not appropriate. Instep, we ought to utilize a strategy that's suitable for little test sizes. 

The plus four method is one such method that is commonly used when the sample size is small. Therefore, to construct a confidence interval for the proportion of defectives, we should use the plus four method.

The plus four strategies may be a strategy for building a certainty interim for an extent when the test estimate is little.

To utilize this strategy, we to begin with include four fanciful perceptions to our test, two of which are flawed and two of which are not imperfect.

This increments the test estimate to 24, which permits us to utilize the typical guess to the binomial dispersion to build the certainty interim.

The equation for the certainty interim utilizing the also four strategies is:

p ± zα/2 √((p + 2) (1 - p + 2) / n + 4)

where:

p is the test extent (number of defectives/test estimate)

zα/2 is the basic esteem from the standard typical dissemination at the level of importance α/2

n is the test estimate (counting the included four nonexistent perceptions)

Therefore, to construct a confidence interval for the proportion of defectives, we should use the plus four method.

The graph K must represent an investment that was compounded continuously because investments that are compounded continuously increase at a faster rate than investments that use either simple interest or are compounded monthly.

How to determine the correct statement about the future value and its graph?

In Mathematics and Financial accounting, continuous compounding interest can be determined or calculated by using this mathematical equation (formula):

[tex]A(t) = P_{0}e^{rt}[/tex]

Where:

A(t) represents the future value.P₀ represents the principal.r represents the interest rate.t represents the time measured in years.

By critically observing the given graph, we can reasonably infer and logically deduce that the graph with line K represent an investment that was compounded continuously because the principal (initial amount of money) increases at a faster rate

1. Range of Surveyed Students: 1,650 to 1,800 students.

2. Range of Students in Orange County: 39,364 to 42,972 students

How did we calculate range of a survey?

To determine the range of surveyed students that agreed with the statement, we need to calculate the minimum and maximum percentages based on the margin of error. Given that 86% of students agreed with the statement and the margin of error is ±3.7%, we can find the range as follows:

Minimum percentage: 86% - 3.7% = 82.3%

Maximum percentage: 86% + 3.7% = 89.7%

Now, we'll apply these percentages to the total number of surveyed students (2,006):

Minimum number of students: 0.823 x 2,006 ≈ 1,650 students

Maximum number of students: 0.897 x 2,006 ≈ 1,800 students

Range of Surveyed Students: 1,650 to 1,800 students

b. To determine the range of grade 10-12 students in OCPS who would likely agree with the statement, we'll apply the same minimum and maximum percentages found earlier (82.3% and 89.7%) to the total number of grade 10-12 students in Orange County Public Schools (47,851):

Minimum number of students: 0.823 * 47,851 = 39,364 students

Maximum number of students: 0.897 * 47,851 = 42,972 students

Range of Students in Orange County: 39,364 to 42,972 students

The above answer is based on the information below provided in the picture;

A research survey of 2,006 public and private school students in the United States (grades 10-12) between April 12 and June 12, 2016 asked students if they agreed with the statement, "If I make a mistake, I try to figure out where I went wrong." The survey found that 86% students agreed with the statement. The margin of error for the survey is +3.7%.

The Columbus Zoo conducts a study to determine whether a household’s income can be used to predict the amount of money the household will give to the zoo’s annual fund drive. The response (i.e. the effect) variable in this study is
a. the Columbus Zoo.
b. a household’s income.
c. the amount of money a household gives to the zoo’s annual fund drive.
d. all households in Columbus.

Answers

The response (i.e. the effect) variable in this study is option (c)  the amount of money a household gives to the zoo's annual fund drive

The response (i.e. the effect) variable in this study is the amount of money a household gives to the zoo's annual fund drive. This is the variable that the study is attempting to predict based on the household's income. The Columbus Zoo is the entity conducting the study, and a household's income is the predictor (i.e. the independent) variable.

The study is focused on the relationship between a household's income and the amount of money it gives to the zoo's annual fund drive, so the response variable is the amount of money given to the fund drive. The study is not attempting to make predictions about all households in Columbus, so option d is not the correct answer.

Therefore, the correct option is (c) the amount of money a household gives to the zoo’s annual fund drive.
