The value of the discount that will be give for the doll is $54.

A percentage simply has to do with the a value or ratio which can be stated as a fraction of 100. It should be noted that when we want to we calculate a percentage of a number, we simply divide it and then multiply the value that is gotten by 100.

From the information, it should be noted that there's a 15% discount. The value of the discount will be:

= 15% × $360

= $54

What is distance between two points?

The length of a straight line in the coordinate plane that connects two points in space is what is referred to as their distance. We use the absolute value to calculate the distance between any two points because it is impossible for this distance to be negative.

Consider, the given points A (-4, -3), B (4, -3), C (4, -7), D (-4, -7).

We have to find the length of AB.

Consider, the distance formula,

[tex]d = \sqrt{(x_2-x_1)^2 +(y_2-y_1)^2}[/tex]

where,

[tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are the points.

Here,

[tex](x_1, x_2) = (-4, -3)\\(x_2, y_2) = (4, -3)[/tex]

Plug these values in the above formula,

[tex]d = \sqrt{(4-(-4))^2+(-3-(-3))^2} \\d = \sqrt{8^2 +0^2} \\d = \sqrt{8^2} \\d = 8[/tex]

Hence, the length of AB is AB = 8 units.

The average rate of change of filling the water heater is solved to be

The results indicate that 1 1/3 is the ratio of the rate of change of water height to time.

The average rate of change for the points t = 3 and t = 6  is solved using the formula

m = (y₀ - y₁) / (x₀ - x₁)

m = (3 - 7) / (3 - 6)

m = (-4) / (-3)

m = 4/3

12.5%

Step-by-step explanation:

The rate of change of function A is greater than the rate of change of function B. This is the statement which best compares the rate of change of the two functions.

What is rate of change?

The pace at which one quantity changes in relation to another quantity is known as the rate of change function. The relationship defining how one quantity changes in relation to the change in another quantity is given by the rate of change formula.

The formula for rate of change is:

[tex]m=\frac{y_{2} -y_{1} }{x_{2}- x_{1} }[/tex]

The points for first function A are

(7,21) and (8,24).

So, the rate of change is:

[tex]m=\frac{24-21}{8-7}[/tex]

m= 3/1 = 3

The points for second function B are

(2,4) and (3,6).

So, the rate of change is:

[tex]m=\frac{6-4}{3-2}[/tex]

m= 2/1 = 2

The rate of change of function A is 3, while the rate of change of function B is 2.

Hence, the rate of change of function A is greater than the rate of change of function B.

A graph which shows the relationship given in the table is: B. graph with the x axis labeled number of days and the y axis labeled total amount of sunglasses and a line going from the point 0 comma 56 through the point 1 comma 54.

In this scenario, the number of days would be plotted on the x-axis (x-coordinate) of the scatter plot while the total amount of sunglasses would be plotted on the y-axis (y-coordinate) of the scatter plot through the use of Microsoft Excel.

From the scatter plot (see attachment) which models the relationship between the number of days and total amount of sunglasses, a linear equation for the line of best fit is given by:

y = -2x + 56

Therefore, the y-intercept is equal to (0, 56).

The correct answers are X=76.5 and Perimeter= 210.9.

Perimeter is the distance around the outside of a shape. It is a measurement of length and is calculated by adding up the lengths of all the sides of a shape. Perimeter is often used to measure the size of outdoor areas such as a garden, park, or pool, or to find the length of fencing needed for a yard.

To solve for x, use the formula x = (P + Q - R)/2 where P, Q, and R are the lengths of the sides of the triangle. Thus, x = (AST + APQ - APR)/2 = (176 + 140 - 126)/2 = 76.5. To find the perimeter of the triangle STU, use the formula Perimeter = ST + SU + TU = 176 + 28 + 6 = 210.9.
