Answer:

Two quantities x and y are said to be proportional if ratio yx for related pairs of x and y is equivalent.

Step-by-step explanation:

Two quantities x and y are said to be proportional if ratio yx for related pairs of x and y is equivalent.

The symbol ∝ is used to denote the proportionality. For example, if x is proportional to y, then it is represented as x∝y and if x is inversely proportional to y, then it is represented as x ∝ 1/y

Answer:

4. Slope of function B = -slope of function A

Step-by-step explanation:

Given:

Function A is given as:

F(x)=-2x+1

The above equation is of the form y=mx+b, where m represents slope of the line.

Therefore, on comparing the function A with the above standard form, er conclude that, slope of function A is -2.

Now, from the graph of function, we consider any two points on the graph and determine the slope of the line using the two points.

Let us consider the points (x_1,y_1)=(1.5,0)\ and\ (x_2,y_2)=(3,3)

Now, the slope of the line passing through these two points is given as:

m_B=\frac{y_2-y_1}{x_2-x_1}=\frac{3-0}{3-1.5}=\frac{3}{1.5}=2

Therefore, slope of function B is 2.

Therefore, the correct relation between the slopes of the two functions is that the slope of function B is negative of the slope of function A.

m_B=-(m_A)=-(-2)=2

A skateboarder descends on a ramp from 172 feet to 67 feet in 15 seconds. What is the average height change in height per second
Tamiku [17]
7 feet per second, 172 minus 67 means he dropped 105 feet then divide that by how many seconds it took to get 7 fps.

A parking lot in the shape of a trapezoid has an area of 12,0521 square meters the length of the other base is 108.6 meters. Wha

Please consider the complete question.

A parking lot in the shape of a trapezoid has an area of 12,052.1 square meters. The length of one base is 82.4 meters and the length of the base is 108.6 meters. What is the width of the parking lot

We will use area of trapezoid to formula to solve our given problem.

\text{Area of trapezoid}=\frac{1}{2}(a+b)\times h, where

a and b represents parallel sides of trapezoid,

h = height of trapezoid.

Width of the trapezoid will be equal to height.

Upon substituting our given values in above formula, we will get:

12,052.1=\frac{1}{2}(82.4+108.6)\times h

12,052.1\cdot 2=2\cdot \frac{1}{2}(82.4+108.6)\times h

24104.2=(191)\times h

\frac{24104.2}{191}=\frac{(191)\times h}{191}

126.2=h

Therefore, the width of the parking lot is 126.2 meters.
