Pre Calc Question for one of my classes
Tatiana [17]

Answer:

Step-by-step explanation:

f(x) is like y in a linear equation. There is one major difference. F(x) tells you what to substitute on the right every time you see an x.

f(a) = -3a + 7

f(b) = -3b + 7

For this question a and b have values. Now work with the right side only. This is the quickest way to get the answer, but it is only marginally correct.

f(a) = -3(-8) + 7 = 24 + 7 = 31

f(b) = -3(7) + 7 = -21 + 7 = - 14

f(a) + f(b) = 31 - 14 = 17

f(a) - f(b) = 31 - (-14) = 31 + 14 = 45

A water storage tank is in the shape of a cone with the pointed end down. If the radius is 21 feet and the depth of the tank is
andre [41]

The volume of the water storage tank is the amount of space in it

The volume of the water storage tank is 6468 cubic feet

<h3>How to determine the volume?</h3>

The given parameters are:

Radius (r) = 21 feet

Height (h) = 14 feet

The shape of the water storage tank is a cone.

And the volume of a cone is:

V = 1/3πr^2h

So, we have:

V = 1/3 * 22/7 * 21^2 * 14

This gives

V = 6468

Hence, the volume of the water storage tank is 6468 cubic feet

Answer:

\mathfrak {last \:option }

\mathfrak\blue{ {option \: 2} }

Step-by-step explanation:

x intercept of a function is the point where it's graph intersects the x axis.

or

simply that value x, where the value of y is 0.

since at x = 2; f(x) =0 that point <u>(2, 0)</u> is the x intercept of the function.
