Step-by-step explanation:

Step 1: Make a formula

$\frac{diameter_1}{volume_1} = \frac{diameter_2}{volume_2}$

$\frac{2}{1600} = \frac{3}{x}$

Step 2: Cross multiply

$2(x) = 3(1600)$

$2x=4800$

Step 3: Divide both sides by 2

$2x/2 = 4800/2$

$x = 2400$

Answer: The volume of the larger cylinder is 2400 cm^3

Solve for the x-max or h :\
$-b/(2a)=-8/(2*-2)=2=k$
plug it in to equation to get k:/
$y(2)=-2(2)^2+8(2)+3$
-8+16+3=11=k
$y=a(x-2)^2+11
$
solve for a by pluging (0,0)
then a= -11/4
$y=-11/4(x-2)^2+11$

Answer:

Step-by-step explanation:

The equation $V=-32t+256$ and the graph below describe the velocity V in feet per second of a ball t seconds after it is shot into the air.

To find the balls velocity after seven seconds, substitute t = 7 into the function expression:

$V(7)=-32\cdot 7+256\\ \\=-224+256\\ \\=32\ ft/sec$

Will give brainlest answer please help

Answer:

-1

Step-by-step explanation:

You can do this two ways, the easiest way is to look at the graph.

What is g(4) means: When the x value equals 4, what does y equal?

Look for the coordinate with the x-value of 4 (it's asking for g(4). Now if you look at the y-value of the coordinate, it should tell you what g(4) is. So since the coordinate is (4,-1), g(4) is -1.

Another way to do it is to plug in 4 for x in the equation. So...

g(4) = -[f(4) - 3)]

g(4) = -[4 - 3]

g(4) = -[1]

g(4) = -1

Geometry help? How would I solve this?

Firlakuza [10]

$\bf \textit{sum of interior angles in a regular polygon}
\\\\\\
n\theta=180(n-2)\qquad 
\begin{cases}
n=\textit{number of sides}\\
\theta=\textit{angle in degrees}
\end{cases}
\\\\\\
\textit{notice, your two polygons, are just two regular octagons}\\
\textit{OCTAgons, thus OCTA = 8, 8 sides, thus}
\\\\\\
n\theta=180(n-2)\qquad n=8\implies 8\theta=180(8-2)
\\\\\\
\theta=\cfrac{180\cdot 6}{8}$

so... that's how much an internal angle is
now, subtract that from 180 and you get the angle outside, in the picture

subtract that outside angle twice from 180, and you get angle "2"
because angle 2 is in the same triangle as those two outside angles, and all internal angles in a triangle is 180, thus 180 - (those two angles) is angle "2"
