Answer:

17 ft.

Step-by-step explanation:

We have been given that Carl dives in and touches the bottom of the pool, 15 feet below the surface of the water.

The elevation of Carl's hand would be -15\text{ ft}.

Cameron is standing on a diving platform 2 feet above the surface. The elevation of Cameron's feet would be 2\text{ ft}.

The vertical distance between Carl's hand and Cameron's feet would be difference of both altitudes.

\text{The vertical distance}=2\text{ ft}-(-15)\text{ ft}

\text{The vertical distance}=2\text{ ft}+15\text{ ft}

\text{The vertical distance}=17\text{ ft}

Therefore, the vertical distance between Carl's hand and Cameron's feet is 17 ft.

The difference between the 2 is simply the sum of the difference between each and the surface of the water (15 + 2)

17 feet apart

A diving board is 10 feet above the surface of the water. At time t = 0, the board propels Chris upward at a rate of 12 feet per
Art [367]

Answer:

Chris will take 0.75 seconds to return to his starting height of 10 feet.

Step-by-step explanation:

Let the height of Chris be represented by h(t) = -16\cdot t^{2}+12\cdot t +10, where h(t) is the height in feet and t, the time in seconds. First, we equalize the formula to a height of 10 feet and simplify the resulting expression, that is:

-16\cdot t^{2}+12\cdot t +10 = 10

-16\cdot t^{2}+12\cdot t = 0

Then, we simplify the expression by algebraic means:

-16\cdot t\cdot \left(t-\frac{3}{4} \right) = 0

Roots of the polynomial are, respectively:

t = 0\,s\,\lor \,t = 0.75\,s

First root represents the initial height of Chris, whereas the second one represents the instant when Christ returns to the same height above the surface of the water. Hence, Chris will take 0.75 seconds to return to his starting height of 10 feet.

Help me please I’m so confused ):

The domain is all the x-values you can use with this function. When dealing with a function like this, you need to ask yourself, what would make the bottom equal to 0? Whatever those numbers are, you do NOT want them in your domain.

A fundamental rule is that you cannot divide by 0 or have 0 as a denominator.

So, you solve x^2+6x=0 to find that x=0 or x=-6 would make the denominator 0.

The domain is everything BUT those two values, because they essentially break your function.
