Answer:

452.16 ft^3

Step-by-step explanation:

Volume formula -

Area × height of the cylinder

A = πr2

A =16(π)

A= 50.24

9 is the height

50.24(9) =452.16

12−5x−4kx=y solve for x

IrinaVladis [17]

Minus 12 both sides
-5x-4kx=y-12
undistribute x
x(-5-4k)=y-12
divide both sides by (-5-4k)
$x=\frac{y-12}{-5-4k}$
$x=\frac{12-y}{4k+5}$

Answer:

$h(t)=-6(t-2)^2+24$

Step-by-step explanation:

Given function:

$h(t)=-6t^2+24t$

where:

h = height (in feet)
t = times (in seconds)

Rewrite in the form $h(t)=a(t-h)^2+k$

The quickest way to do this is to expand $h(t)=a(t-h)^2+k$ and compare coefficients with the original function.

$\begin{aligned}h(t)& =a(t-h)^2+k\\ & = at^2-2aht+ah^2+k\end{aligned}$

Comparing coefficients with $h(t)=-6t^2+24t$

$\begin{aligned}\implies at^2& =-6t^2\\ a &=-6\end{aligned}$

$\begin{aligned}\implies -2aht & =24t\\ -2(-6)ht& =24t\\ 12ht & = 24t\\ 12h & = 24\\ h & = 2\end{aligned}$

$\begin{aligned}\implies ah^2+k & = 0\\(-6)(2)^2+k &=0\\ -24+k & =0\\ k &=24 \end{aligned}$

Therefore, substituting the found values into the equation:

$h(t)=-6(t-2)^2+24$

Cam has a collection of ceramic chickens. 10% of the chickens were given to him as gifts, and he bought the rest himself. If 11

otez555 [7]

Hello! To find out the amount of ceramic chickens he has in total, we can write and solve a proportion. Set it up like this:

11/x = 10/100

This is because 11 was just the 10% given as gifts, and we are looking for the total amount. Cross multiply the values in order to get 1,100 = 10x. Divide each side by 10 to isolate the x. 1,100/10 is 110. Let's check. 110 * 10% (0.1) = 11. There. x = 110. Cam has 110 ceramic chickens total.
