What is the range of the function f(x)=7-3x when the domain is {-4, -2, 0, 2}?

klemol [59]

Answer:

{19,13,7,1}

Step-by-step explanation:

Since the domain is the input we have to plug in each of those numbers to get the range ( or the output.) When we plug in -4 we get 19. When we plug in -2 we get 13, when we plug in 0 we get 7 and when we plug in 2 we get 1. (:

Find the surface area of the pyramid. the surface area of the pyramid is __in squared.

iVinArrow [24]

Answer:

$561.08in^{2}$

Step-by-step explanation:

$S A = lw + l$ $\sqrt{(\frac{w}{2})^{2} + h^{2} } + w$ $\sqrt{(\frac{l}{2})^{2} + h^{2} }$

$SA = 14(14) + 14 \sqrt{(\frac{14}{2})^{2} + 11^{2} }+ 14 \sqrt{(\frac{14}{2})^{2} + 11^{2} } = 561.08in^{2}$

The diameter of a circle is 6 in. Find its area to the nearest tenth.

Marrrta [24]

Answer and Step-by-step explanation:

The area formula for a Circle is:

A = $\pi r^2$

Diameter is equal to the radius times 2.

So, divide the diameter to get the radius.

6 divided by 2 equals 3.

Now, plug it into the formula.

$A = \pi (3)^{2}$

A = $9\pi$

Plug this into your calculator by multiplying 9 by pi.

We get the answer to be 28.3 when rounded to the nearest tenth.
