Hey there! :)

The formula for finding volume of a cone : ( π · r² · h ) ÷ 3

Radius = 6
6² = 6 · 6 = 36

Height = 8

π = 3.14

Multiply:

8 × 6 × 3.14 = 150.72

The volume is 150.72 cubic meters

Hope this helps :)

$\\ \rm\Rrightarrow f(x)=-5cos\dfrac{x}{2}+5$

Compare to standard equation of SHM

$\\ \rm\Rrightarrow y=Acos(\omega x+\phi)$

Here

Amplitude=A=-5

$\\ \rm\Rrightarrow \omega x=\dfrac{x}{2}$

$\\ \rm\Rrightarrow \omega=1/2$

Well the above one are for extra knowledge .

Solution:-

$\\ \rm\Rrightarrow 10=-5cos\dfrac{x}{2}+5$

$\\ \rm\Rrightarrow 10-5=-5cos\dfrac{x}{2}$

$\\ \rm\Rrightarrow 5=-5cos\dfrac{x}{2}$

$\\ \rm\Rrightarrow cos\dfrac{x}{2}=-1$

$\\ \rm\Rrightarrow \dfrac{x}{2}=cos^{-1}(-1)$

$\\ \rm\Rrightarrow \dfrac{x}{2}=\pi$

$\\ \rm\Rrightarrow x=2\pi$

So.

$\\ \rm\Rrightarrow x=2\pi+2\pi n$

Solve for AB. Round your answer to the nearest tenth if necessary.

Answer:

AB = 55.25

Step-by-step explanation:

Set up an equation where the length of AB is equal to AC minus BC. This will allow us to solve for x, and then the length of AB.

AB = AC - BC

5x + 9 = 87 - (3x + 4)

5x + 9 = 87 - 3x - 4

5x + 9 = 83 - 3x

8x + 9 = 83

8x = 74

x = 9.25

Now plug 9.25 in for x in the equation for AB

AB = 5x + 9

AB = 5(9.25) + 9

AB = 46.25 + 9

AB = 55.25

How do you do the bottom portion of this? It’s my younger sister’s homework . I’m a sophomore and have no idea how to do it!

Hello!

Looking at how you set up the proportion, it is correct.

Although, the multiplication is incorrect.

You are supposed to multiply 68 by 25 which comes out to 1700. Then, you should divide it by 100 to get x = 17.

$\frac{x}{25} = \frac{68}{100}$

$100x = 68 * 25$

$100x = 1700$ (divide both sides by 100)

$x=17$

Therefore, you should expect Sparky to catch it 17 times.
