The water usage at a car wash is modeled by the equation W(x) = 5x3 + 9x2 − 14x + 9, where W is the amount of water in cubic feet and x is the number of hours the car wash is open. The owners of the car wash want to cut back their water usage during a drought and decide to close the car wash early two days a week. The amount of decrease in water used is modeled by D(x) = x3 + 2x2 + 15, where D is the amount of water in cubic feet and x is time in hours. Write a function, C(x), to model the water used by the car wash on a shorter day. C(x) = 5x3 + 7x2 − 14x − 6 C(x) = 4x3 + 7x2 − 14x + 6 C(x) = 4x3 + 7x2 − 14x − 6 C(x) = 5x3 + 7x2 − 14x + 6

The information that we collects while finding probability is given below.
What is probability?
Probability denotes the likelihood of something happening. It is a mathematical discipline that deals with the occurrence of a random event. The value ranges from zero to one. Probability has been introduced in mathematics to predict the likelihood of occurrences occurring. Probability is defined as the degree to which something is likely to occur. This is the fundamental probability theory, which is also utilized in the probability distribution. To determine the likelihood of a particular event occurring, we must first determine the total number of possibilities.
Now,

Step-by-step explanation:
The equation for a perpendicular has a slope that is the opposite reciprocal, meaning if the original slope is negative, the perpendicular slope is positive. So you can eliminate the bottom two answers since they do not have an opposite slope.
Reciprocal means to basically flip the fraction. The original fraction in 5/4 so the reciprocal is 4/5.

Dependent and Independent variables:In mathematics, a dependent variable is a variable that depends on one or more independent variables.
An independent variable, on the other hand, is a variable that does not depend on any other variable and is used to explain changes in the dependent variable.
Here we have
The table shows the relationship
“Mason rode 15 miles per hour on his bicycle.”
Hours (h) 1 2 3 4 5
Miles (m) 15 30 45 60 75
Since the number of miles, Mason rides depends on the number of hours he rides, we can say that the variable m is the dependent variable and the variable h is the independent variable and m is the dependent variable.
As Mason's speed is constant at 15 miles per hour, we can see that the number of miles he rides increases at a constant rate with respect to time So we can say that the number of hours causes a change in the number of miles ridden.
Therefore
The correct statements are:
The variable h is the independent variable.
The variable m is the dependent variable.
The number of miles increases as time increases.
The number of hours causes a change in the number of miles ridden.

That after 12 hours, there are -9 gallons of water in the tank.
What is number?Number is a mathematical object used to measure, count, or label. It can represent a quantity, magnitude, or position in a sequence. Numbers are used in many areas of life, including science, engineering, economics, finance, and even art. Numbers can also be used to represent abstract concepts such as time, emotion, or other qualities.
The graph below shows the points on the coordinate plane with the ordered pairs given. The points indicate that the tank of water is leaking at a rate of 3 gallons per hour. This can be calculated by subtracting 24 gallons from 27 gallons which is the difference between the first two points, and dividing by the difference in time which is 5-1, or 4 hours. This can be generalized to the other points, where the differences between the points divided by the difference in time will always be 3 gallons per hour.
This is happening because the rate of the leak is constant and therefore the decrease in gallons of water will follow the same pattern. As time increases, the number of gallons of water in the tank decreases by 3 for every hour that passes.
This can be used to determine the number of gallons in the tank at any given time by using the equation:
Gallons = 27 - (3 x hours)
Therefore, if the tank has been leaking for 12 hours, the equation becomes:
Gallons = 27 - (3 x 12)
Gallons = 27 - 36
Gallons = -9
This means that after 12 hours, there are -9 gallons of water in the tank.

The surface area of the regular pyramid is 536.40 square inches
Finding the surface area of the regular pyramidFrom the question, we have the following parameters that can be used in our computation:
Base length, l = 13 in
Base width , w = 15 in
Height, h = 10 in
The surface area of the regular pyramid is calculated as
Area = lw + 1/2w√[4h² + l²] + 1/2l√[4h² + w²]
Substitute the known values in the above equation, so, we have the following representation
Area = 13 * 15 + 1/2 * 15 *√[4 * 10² + 13²] + 1/2 * 13√[4 * 10² + 15²]
Evaluate
Area = 536.40

1. The quadratic function for the Area in terms of x: A(x) = 24x.
2. The cross-sectional area is maximized when the depth of the gutter is 0.
3. The maximum cross-sectional area is square inches 0.
To determine the depth of the gutter that maximizes its cross-sectional area and allows the greatest amount of water to flow, we need to follow a step-by-step process.
1. Write a quadratic function for the area in terms of x:
The cross-sectional area of the gutter can be represented as a rectangle with a width of 24 inches and a depth of x. Therefore, the area, A(x), is given by A(x) = 24x.
2. The cross-sectional area is maximized when the depth of the gutter is:
To find the value of x that maximizes the area, we need to find the vertex of the quadratic function. The vertex of a quadratic function in form f(x) = ax² + bx + c is given by x = -b/(2a). In our case, a = 0 (since there is no x² term), b = 24, and c = 0. Thus, the depth of the gutter that maximizes the area is x = -24/(2 * 0) = 0.
3. The maximum cross-sectional area is square inches:
Substituting the value of x = 0 into the quadratic function A(x) = 24x, we get A(0) = 24 * 0 = 0. Therefore, the maximum cross-sectional area is 0 square inches.

Step-by-step explanation:
To find the mean of these numbers, we'll add them together, then divide by how many numbers there are.
\(\frac{-5+12+24+46+60}{5}\\\\=\frac{137}{5}\\\\=27.4\)
\(\huge{\purple{\underline{\underline{\bf{\pink{ANSWER:-}}}}}}\)
Arithmetic mean is also called as average mean. This is given by the summation of no.s present to how many no.s there are.
Calculating arithmetic mean gives,
\(:\implies\sf{ \frac{ - 5 + 12 + 24 + 46 + 60}{5} }\)\(:\implies\sf{ \frac{ - 5 + 142}{5} }\)\(:\implies\sf{ \frac{137}{5} }\)\(:\implies\sf{27.4}\)The arithmetic mean of the above given no.s is 27.4what is the property of 3x(5x7)=(3x5)7
The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.
In the equation you provided: 3x(5x7) = (3x5)7
The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.
