To prove:

The given graph is a function.

The given graph is a function if and only if no x value has more than one value of y, or we can say that a graph is a function iff no vertical line intersects the graph in more than one point.

Thus, by the given graph it is clear that for x = 7 their are two values for y that is y = -6 , -7

So, the given graph is not a function

If a diver dives from a cliff that has a height of 125 feet, The dive lasted approximately 2.80 seconds

A diver dives from a cliff that has a height of 125 feet

The formula h = 16t², where t is time in seconds and h is the distance in feet traveled by a free-falling body or object

125 = 16t²

125/16 = t²

t = √(125/16)

t = √125/√16

t = 5√5 /4

t = 1.25 x 2.23

t = 2.795

t = 2.80

Therefore, if a diver dives from a cliff that has a height of 125 feet, The dive lasted approximately 2.80 seconds

The cost of 20 apples is such that the ratio of apples to cost maintained or each apple costs the same amount is $4.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

As per the given,

Melissa brought 6 apples for $1.20.

The ratio of cost to apple ⇒

1.20/6

Now let's suppose the cost of 20 apples is x dollars.

The ratio of cost to apple ⇒

x/20

Since the cost of each apple is the same, therefore, both ratios must be the same.

x/20 = 1.20/6

x = 20(1.20/6)

x = 4

Hence "The cost of 20 apples is such that the ratio of apples to cost maintained or each apple costs the same amount is $4".

The first piece = 20m

The second piece = 40m

The third pice = 8x = 160m

Given:

Total length of wire = 220m

2nd piece = 2 times the 1st piece

3rd piece = 4 times the 2nd

To find:

The length of each of the piece

The wire was cut into 3:

1st piece + 2nd piece + 3rd piece = 220m

let the first length = x

2nd length = 2 (1st length) = 2(x)

2nd length = 2x

3rd length = 4(2nd piece) = 4(2x)

3rd length = 8x

The first piece = 20m

The second piece = 2x = 2(20) = 40m

The third pice = 8x = 8(20) = 160m

The height of the pile increasing at the rate of  4.56 inches per minute when the pile is 10 ft high.

In given situation, the rate of change of height is equal to the rate of change of volume, divided by the base area.

First we find the base area.

base area = (π/4)d²

base area = (π/4)10²

base area = 25π ft²

base area ≈ 78.5 ft²

Then the rate of change of height would be,

(30 ft³/min)/(78.5 ft²)

≈ 0.38 ft/min

= 4.56 inches / minute

Therefore, the height of the pile increasing at the rate of  4.56 inches per minute when the pile is 10 ft high.

Part A) Option c is correct answer. 6 x 9 can be used to model the area of the vegetable garden.

Part B) Total area of the garden in square feet is 62 square feet.

What do you mean by area?

Area is a unit of measurement used to describe a region's size on a flat or curved surface. While a plane region or area refers to the area of a shape or planar lamina, a surface region or plane area refers to the area of an open surface or the boundary of a three-dimensional object.

To calculate the area we first individually calculate the area of the garden with flowers and vegetables,

Area of the garden where flowers are planted:

Area = length x breadth

Area = 4 x 2 = 8 square feet

Area of garden where vegetables are planted:

Area = 6 x 9 = 54 square feet

Total area of the garden = 8 + 54

Total area of the garden = 62 square feet

Given

capacity of 500 pounds.

weights of the passengers are 107 pounds, 172 pounds and 129 pounds.

you weigh 136 pounds

Find

is it safe for you to enter the elevator?

Explanation

as total pounds in the elevator = 107 + 172 + 129 = 408 pounds

total pounds included my weight = 408 + 136 = 544 pounds

capacity = 500 pounds

so , extra pounds = 544 - 500 = 44 pounds

so , no it is not safe for you to enter the elevator.

Final Answer

Therefore , No the weigh capacity would be exceeded by 44 pounds
