Part a - C = 120 + 5x

Part b - A = [120 + (5 x (x)] / x

Part c - The number of hours you must play before the average cost per hour drops to $10 per hour is 15 hours.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Membership fees = $120

Cost per hour = $5

x = number of hours

The equation that represents the total cost:

C = 120 + 5x

The equation that represents the average cost per hour:

A = [120 + (5 x (x)] / x

From the graph, we can assume that the y-axis indicates the average cost per hour and the x-axis indicates the number of hours.

We see that in 16 hours the average cost per hour is $10 so the number of hours to play before the average cost per hour drops to $10 per hour is 15 hours.

Thus,

Part a - C = 120 + 5x

Part b - A = [120 + (5 x (x)] / x

Part c - The number of hours you must play before the average cost per hour drops to $10 per hour is 15 hours.

The inverse function as g⁻¹ (h)  = [(h+6)/10]² which is the correct answer would be an option (E).

The inverse function is defined as a function obtained by reversing the given function.

To determine the inverse of a function, all you have to do is switch where h and g are and resolve for g.

So after switching h and g,

g = g(h) = 10√h - 6

becomes

h = 10√g - 6

Now, we solve for h regularly.

h + 6 = 10√g

(h + 6)/10 = √g

[(h+6)/10]² ⇒ g = [(h+6)/10]² = g(x)

Therefore the inverse of g(x) is g⁻¹ (h)  = [(h+6)/10]²

Hence, the inverse function as g⁻¹ (h)  = [(h+6)/10]²

From the given vertices, the area of the polygon is 28.

The rectangle is a quadrilateral.  The classification for quadrilaterals is given by the length of sides and angles. For a rectangle,  the opposite sides are equal and parallel and their interior angles are equal to 90°.

A rectangle is a geometric figure that has 4 sides called: base and height. Due to its characteristics, the rectangle presents two bases (B) and two heights (H).

The area of a rectangle is given by the multiplication between the base and the height.

First, you should plot the points, then see image 1.

From the figure, it is possible to see that the bases ( AB and CD) = 5-3=2

and heights (AC and BD) =-7-(-7)=7+7=14. Thus,

Considering the definition of an equation and the way to solve it, the money earned by Adriano's online business this month is $1,150.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.

In this case, you know that every month, Adriano receives a subscription fee of $5 from each of the subscribers to his website. Then, the amount of money earned by Adriano's online business each month will be represented by the following equation:

Money earned by Adriano's online business each month= $5x

where x is the number of subscribers on the website.

On the other hand, you know:

Then, the number of subscribers this month can be calculated as:

Number of subscribers this month = 200 + 40 - 10

Number of subscribers this month = 230

So, the amount of money earned by Adriano's online business this month is calculated by substituting this value in the equation above:

Money earned by Adriano's online business this month= $5×230 subscribers

Money earned by Adriano's online business this month=$1,150

Answer:

121° and 59°

Step-by-step explanation:

We'll assign the two angles 'a' and 'b'. Since they are supplementary, this means they add to 180°. We can model this peoblem with the expressions:

a + b = 180° and a - b = 62°

Let's use the second equation to find a substitution for a:

a - b = 62°

a = 62° + b

Now substitute this in the first equation and solve:

(62° + b) + b = 180°

62° + 2b = 180°

2b = 118°

b = 59°

59° + 62° = 121° this is angle a

This will ensure the equal representation from each group in population. Stratified sampling helps to reduce the variability of the estimates also.

Answer:

y = 3x + 1

y = -x + 5

Step-by-step explanation:

Take the system of equations and substitute (1 ,4) in any one of the equations. If both the sides are justified, then (4,1) is the solution to that pair of equations.

  1) y = -3x  - 1   ---------(I)

     y = -x + 5

Substitute (1,4) in equation (I)

        4 = -3*1 - 1

        4 = -3-1

        4 ≠ -4

So, (1, 4) is not a solution.

2) y = 3x + 1   ---------------(II)

   y = - x + 5

Substitute (1 ,4) in equation (II)

      4 = 3*1 + 1

       4 = 3 + 1

The correct option regarding the linear regression equation is:

No, the equation is not a good fit because the sum of the residuals is a large number.

To find the equation, we need to insert the points (x,y) in the calculator.

In possession of the equation, the residuals are given by the difference of the predicted values(with the equation) and the actual values.

The model represents a good fit if the sum of the residuals is close to 0.

For this problem, the sum of the residuals is given by:

90 - 50  - 100 - 100 + 150 - 50 = -60.

The sum is a large number, hence the model is not a good fit.

The scalar multiplication [tex]k(\overrightarrow{a}+\overrightarrow{b})=k\overrightarrow{a}+k\overrightarrow{b}[/tex]has been proved.

Scalar Multiplication Property:

Basically a scalar means the real number.

The scalar multiplication property states that the product of a sum or difference of a number is equal to the sum or difference of the products.

The general form of scalar multiplication as follows:

k (A + B) = kA + k B

where

k is the scalar.

Given,

Let

[tex]\overrightarrow{a}= < x_1,y_1 >[/tex]

and

[tex]\overrightarrow{b}= < x_2,y_2 >[/tex]

Then we have to prove the following scalar multiplication property,

[tex]k(\overrightarrow{a}+\overrightarrow{b})=k\overrightarrow{a}+k\overrightarrow{b}[/tex]

We know that,

"The vector is an object that has both a magnitude and a direction. And  vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction."

Here we have two vectors like [tex]\overrightarrow{a},\overrightarrow{b}[/tex].

Now we need to use the definition of the scalar multiplication property,

Then, the LHS of the expression is written as,

[tex]\implies k(\overrightarrow{a}+\overrightarrow{b})[/tex]

Apply the values of the vectors then we get,

=> k(<x₁, y₁> + <x₂, y₂>)

When we expand the terms then we get,

=> k<x₁, y₁> +  k<x₂, y₂>

And it can be written as,

[tex]\implies k\overrightarrow{a}+k\overrightarrow{b}[/tex]

Therefore, the scalar multiplication property has been proved.
