If f(x)=4x2=1 and g(x)=x2-5, find (f-g)(x)<br>A:3x2+6<br>B:5x2-6<br>C:3x2-4<br>D:5x2-4

Alex787 [66]

For this case we have the following functions:

$f (x) = 4x ^ 2 + 1\\g (x) = x ^ 2-5$

We must find $(f-g) (x):$

By definition of operations with functions we have:

$(f-g) (x) = f (x) -g (x)$

So:

$(f-g) (x) = f (x) -g (x) = 4x ^ 2 + 1- (x ^ 2-5) = 4x ^ 2 + 1-x ^ 2 + 5 = 3x ^ 2 + 6$

Answer:

Option A

$3x ^ 2 + 6$

The prism shown in the diagram has a volume of 39 units^3. What is the volume of the pyramid? Explain your reasoning. I WILL GIV

jolli1 [7]

The volume of the pyramid is 13 units³.

<h3>What is the volume of the pyramid?</h3>

A pyramid is a 3-dimensional shape that is made up of a rectangular base and 4 triangular faces. The volume of a pyramid is one-third that of a prism.

Volume of a pyramid = 1/3 x prism

1/3 x 39 = 13

A cone with a radius 2 units is shown below. Its volume is 29 cubic units. Find the height of the cone

rusak2 [61]

Answer:

The height of the cone is $6.9\ units$

Step-by-step explanation:

we know that

The volume of the cone is equal to

$V=\frac{1}{3}Bh$

where

B is the area of the circular base of the cone

h is the height of the cone

In this problem we have

$V=29\ units^{3}$

$r=2\ units$

$B=\pi r^{2}$

substitute the value of r

$B=\pi (2)^{2}=4 \pi\ units^{2}$

<em>Find the height of the cone</em>

$29=\frac{1}{3}(4 \pi)h$

$h=29*3/(4 \pi)$

assume $\pi=3.14$

$h=29*3/(4*3.14)=6.9\ units$
