Answer:

Step-by-step explanation: y+9=-3(x-4)......given equation

This equation can be expanded further and simplified

y+9=-3x+12

We want to put the equation into the form y=mx+b so we can read its characteristics

To do this we need to get y on its own. We must take 9 from both sides

y+9-9=-3x-9+12

y=-3x+3

The equation has a gradient or slope or m =-3 and it cuts the y-axis at +3 or is the yintercept

A plot of all the ordered pairs for the values in the domain is shown in the graph attached below.

In Mathematics, a domain can be defined as the set of all real numbers for which a particular function is defined. This ultimately implies that, a domain is the set of all possible input values (x-values) to a function and the domain of a graph consist of all the input numerical values which are shown on the x-axis.

Based on the values given for the domain of this function, the ordered pairs would be calculated as follows:

When x = -8, we have;

y = 1/2(-8) + 1

y = -3

Ordered pair = (-8, -3)

When x = -4, we have;

y = 1/2(-4) + 1

y = -1

Ordered pair = (-4, -1)

When x = 0, we have;

y = 1/2(0) + 1

y = 1

Ordered pair = (0, 1)

When x = 2, we have;

y = 1/2(2) + 1

y = 2

Ordered pair = (2, 2).

When x = 6, we have;

y = 1/2(6) + 1

y = 4

Ordered pair = (6, 4)

The equation that represents the number of time a cricket chirp (y) given the temperature (x) in degree Fahrenheit is y = 0.23 x + 40

Steps to translate a word problem into an equation or a function:

- Assign the unknowns to variables

- Identify which one is independent variables, which one is dependent variables. The independent variable will become the input while the dependent variable will become the output.

In the given problem, there are two variables:

- temperature in the air (in Fahrenheit)

- number of time a cricket chirp

From the problem, we can conclude that the number of time a cricket chirp depends on the temperature of the air. Hence,

independent variable =  temperature in the air (in Fahrenheit)

dependent variable = number of time a cricket chirp

Let:

y =  number of time a cricket chirp

x =  temperature in the air (in Fahrenheit)

It is said: The number of chirp per minute is equal to 0. 23 times the temperature of the air, in degree Fahrenheit, plus forty.

A function f such that f '(x) = 3x^3 and the line 81x + y = 0 is tangent to the graph of f is f(x) = 3x^4/4 + 729/4.

In the given question, we have to find a function f such that f'(x) = 3x^3 and the line 81x + y = 0 is tangent to the graph of f.

The given function is f'(x) = 3x^3.

No integrating on both side,

f(x) = [tex]\int3x^3dx[/tex] + C

f(x) = 3x^4/4 + C

As given, the line 81x + y = 0 is tangent to the graph of f.

So, slope at point of tangent; f'(x) = -81

So, 3x^3 = -81

Divide by 3 on both side, we get

x^3 = -27

Taking cube root on both side, we get

x = -3

So putting the value of x in 81x + y = 0, we get

y = 243

Thus, f(x) passes through (-3, 243).

So, 243 = 3/4(81) + C

Multiply by 4 on both side, we get

972 = 243 + 4C

Subtract 243 on both side, we get

4C = 729

Divide by 4 on both side, we get

C = 729/4

So, f(x) = 3x^4/4 + 729/4

Step-by-step explanation:

Answer:

Read carefully below

Step-by-step explanation:

In general, the inverse of a function f(x) is a function g(x) such that f(g(x)) = g(f(x)) = x for all values of x in the domain of f(x) and g(x). To find the inverse of a function, we need to switch the input and output variables and solve for the new output variable.

In this case, we are given the function -2f(x+5)-4. To find the inverse of this function, we need to switch the input and output variables and solve for the new output variable, which we will call y. We can do this by first moving all the terms to one side of the equation, and then solving for y:

-2f(x+5) - 4 = y

-2f(x+5) = y + 4

f(x+5) = (y + 4) / -2

This is the inverse function of -2f(x+5)-4. However, keep in mind that not all functions have inverses. In particular, a function must have the property that it is one-to-one (i.e. it maps unique inputs to unique outputs) in order to have an inverse. It is not clear from the given information whether the function -2f(x+5)-4 is one-to-one, so it is possible that it does not have an inverse.

Using the normal distribution, the middle 50% would be expected to be in the range of 250 to 270 days.

Using the central limit theorem, for the samples of 36, the middle 50% would be expected to be in the range of 258 to 262 days.

A sort of continuous probability distribution for a real-valued random variable is the normal distribution or the Gaussian distribution.

Normal Distribution of Probabilities

The z-score formula, which for a measure X, in a set with mean and standard deviation, is given by: can be used to address problems with normal distributions.

Z = (X - μ)/σ

The z-score calculates the measure's standard deviation from the mean.

A p-value, or percentile of X, is assigned to each z-score.

Mean (μ) = 260.

Standard deviation (σ)= 15 .

The normal distribution is symmetric, which means that the middle 50% is between the 25th percentile and the 75th percentile.

The 25th percentile is X when Z has a p-value of 0.25, so X when Z = -0.675.

The 75th percentile is X when Z has a p-value of 0.75, so X when Z = 0.675.

Lower bound:

Z = (X - μ)/σ

⇒ -0.675 = (X - 260)/15

⇒ X - 260 = -0.675*15

⇒ X - 260 = -10.125

⇒ X = 260 - 10.125

⇒ X ≈ 250

Upper bound:

Z = (X - μ)/σ

⇒ 0.675 = (X - 260)/15

⇒ X - 260 = 0.675*15

⇒ X - 260 = 10.125

⇒ X = 260 + 10.125

⇒ X ≈ 270

The middle 50% of pregnancies would be in the range of 250 to 270 days.

For sample of 36: By the Central Limit Theorem, the standard deviation of the sampling distribution of sample means of size n is given by .

Sample of 36, thus n=36, s=15/√36

⇒ s=15/6

⇒ s=2.5

Lower bound:

Z = (X - μ)/s

⇒ -0.675 = (X - 260)/2.5

⇒ X - 260 = -0.675*2.5

⇒ X - 260 = -1.69

⇒ X = 260 - 1.69

⇒ X ≈ 258

Upper bound:

Z = (X - μ)/s

⇒ 0.675 = (X - 260)/2.5

⇒ X - 260 = 0.675*2.5

⇒ X - 260 = 1.69

⇒ X = 260 + 1.69

⇒ X ≈ 262

let x as hotdog and x + 42 as soda

x + x + 42 = 250

2x + 42 = 250

2x + 42 - 42 = 250 - 42

2x = 208

x = 104

sodas sold: x + 42 = 104 + 42 = 146 sodas

hotdogs sold: x = 104 hotdogs

Step-by-step explanation:

Answer:

104 hot dogs sold

146 sodas sold

Step-by-step explanation:

s=number of sodas. h=number of hotdogs

s+h=250

s=h+42  ==> there were 42 more sells for soda than compared to hot dog

h+42+h=250  ==> plugin h+42 for s

h+h+42=250 ==> simplify

2h+42=250 ==> solve for h

2h+42-42=250-42 ==> isolate h by subtracting 42 on both sides

2h = 208

h = 208/2

h = 104 hot dogs sold

s=104+42  ==> plug in 104 for h in s=h+42

s = 146 sodas sold

Step-by-step explanation:

Note:

[tex]P=[/tex] Perimeter

[tex]L=[/tex] Length

[tex]W=[/tex] Width

The perimeter of a rectangle is the sum of all its sides.

We can say

[tex]P=L+L+W+W[/tex]

Which simplifies to

[tex]P=2L+2W[/tex]

This is the equation to find the perimeter of a rectangle.

We are given the perimeter which is 42.

We are also given that the length is the sum of twice its width and 3.

So we can write

[tex]42=2L+2W\\L=2W+3[/tex]

Lets solve using substitution.

Substitute [tex]L=2W+3[/tex] into the first equation.

[tex]42=2W+2(2W+3)[/tex]

Expand the right side of the equation then simplify.

[tex]42=2W+4W+6\\42=6W+6[/tex]

Subtract 6 from both sides.

[tex]36=6W[/tex]

Divide both sides by 6 to isolate [tex]W[/tex].

[tex]W=6[/tex]

Perform a back substitution.                                                                           Substitute [tex]W=6[/tex] into the second equation, [tex]L=2W+3[/tex]

Answer:

m = -21.

Step-by-step explanation:

To solve this equation, we can use the distributive property to expand the left side and the right side of the equation:

19(2m - 16) = 13(2m + 4)

38m - 304 = 26m + 52

Then we can combine like terms on both sides of the equation to obtain:

38m - 26m = 52 - 304

12m = -252

Finally, we can divide both sides of the equation by 12 to find the value of m:

12m / 12 = -252 / 12

m = -21

Therefore, the value of m that satisfies the equation is m = -21.

To find the area of a triangle, we can use the formula:

Area = (base * height) / 2

To find the area of triangle ABC, we first need to find the base and the height.

Since angle B is 75 degrees, we can use the fact that the sum of the angles in a triangle is 180 degrees to find the measure of angle A: 180 - 75 - 90 = 15 degrees.

Then, we can use the fact that the measure of an angle in a triangle is proportional to the length of the side opposite that angle to find the length of side AC:

AC/AB = m∠A/m∠B

AC = (m∠A/m∠B) * AB

Substituting, we get:

AC = (15/75) * 12 = 3

Now that we know the base and the height of the triangle, we can use the formula to find the area:

Area = (3 * 12) / 2 = 18

Therefore, the area of triangle ABC is 18 square cm.

The measurement of angles △XYZ are ∠X = 59°, ∠Y = 89°, and ∠Z = 32°.

The measurement of angles △LMN are ∠L = 59°, ∠M = 89°, and ∠N = 32°.

What is angle?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Given that, △XYZ and △LMN are similar triangle.

Since the triangles are similar, thus the measurement of triangles are similar.

Therefore,

∠X = ∠L, ∠Y = ∠M, ∠Z = ∠N.

∠Y = ∠M = 89° and ∠Z = ∠N = 32°.

The sum of all interior angles of triangle is 180°.

∠X + ∠Y + ∠Z = 180°

∠X + 89° + 32° = 180°

∠X + 121° = 180°

Subtract 121° from both sides:

∠X  = 59°

∠X = ∠L = 59°.

Multiply this with the starting balance $1367.90 and we get:

0.007916667*1367.90 = 10.8292 which rounds to 10.83

The interest payment for the 1st month is $10.83; which means the principal payment would be 400-10.83 = 389.17

This principal payment will then drop the balance from $1367.90 to 1367.90-389.17 = 978.73 dollars.

The value $978.73 is now the starting balance of the 2nd month. This process of...

Many credit card companies and banks offer free calculators on their website, or you can find similar free calculators online elsewhere, that will quickly calculate a table like shown above. It is called an amortization table or amortization schedule.

With the exception of the 4th month, each row has the principal and interest add to the $400 monthly payment. The last row will have a payment of 1.51+191.12 = 192.63 dollars.

The total amount paid back would be 400+400+400+192.63 = 1392.63 dollars. This is the sum of the values in the "payment" column.

Here's another way to determine the answer.

In this case,

Let's solve for the variable n. We'll need logarithms to isolate the exponent.

Part 1

Part 2

[tex]\displaystyle 1 - (1.007916667)^{-n} = 10.8292087893/400\\\\\\\displaystyle 1 - (1.007916667)^{-n} = 0.0270730\\\\\\\displaystyle -(1.007916667)^{-n} = 0.0270730-1\\\\\\\displaystyle -(1.007916667)^{-n} = -0.9729270\\\\\\\displaystyle (1.007916667)^{-n} = 0.9729270\\\\\\[/tex]

Part 3

[tex]\displaystyle \log((1.007916667)^{-n}) = \log(0.9729270)\\\\\\\displaystyle -n*\log(1.007916667) = \log(0.9729270)\\\\\\\displaystyle n = -\log(0.9729270)/\log(1.007916667)\\\\\\\displaystyle n = 3.4805965\\\\\\[/tex]

"a" being the slope, "b" the y-intercept (the y-value when x = 0).

we see the y-value for x = 0 is 3. that is "b".

for the slope we need 2 points and calculate the x- and y- coordinate differences.

always look for points with integer coordinates.

I see e.g. (0, 3) and (3, 2).

x changes by +3 (from 0 to 3).

y charges by -1 (from 3 to 2).

the slope "a" = -1/+3 = -1/3

the equation is then

y = (-1/3)x + 3

7.

we do exactly the same things.

we see the y-value for x = 0 is +1. that is "b".

I see e.g. these points : (0, 1) and (3, 2).

x changes by +3 (from 0 to 3).

y changes by +1 (from 1 to 2).

the slope "a" is +1/+3 = 1/3.

the equation is

y = (1/3)x + 1

8.

and again the same things.

we see the y-value for x = 0 is +3. that is "b".

I see e.g. these points : (0, 3) and (-3, 0).

x changes by -3 (from 0 to -3).

y changes by -3 (from 3 to 0).

the slope "a" is -3/-3 = 3/3 = 1.

the equation is

y = x + 3
