Answer:

5.6 meters

Step-by-step explanation:

V = pi r^2 h

We want to solve for h

Divide each side by pi r^2

V/ pi r^2 = pi r^2 h/ pi r^2

V/ pi r^2 =h

We know v = 440 pi = 22/7 and r = 5

440 / ( 22/7 * 5^2) = h

440 / (22*25/7) = h

440*7/550 = h

5.6 = h

Functions f(x) and g(x) are shown below. f(x) = x2. . g(x) = x2 - 8x + 16. In which direction and by how many units should f(x)

Aliun [14]

The original function is given by:
$f (x) = x ^ 2
$
We apply the following transformation:
Horizontal displacements:
Suppose k> 0
To move the graph k units to the right, we must graph f (x-k)
Applying the transformation for k = 4 we have:
$g (x) = f (x-4)

g (x) = (x-4) ^ 2

g (x) = x ^ 2 - 8x + 16$
Answer:
B. Right by 4 units

Michele wanted to measure the height of her school’s flagpole. She placed a mirror on the ground 48 feet from the flagpole, then

zepelin [54]

Refer to the diagram below for the sketch of the position of the mirror, Michelle, and the flagpole.

Using similar triangle concept, to find the height of the flagpole, we first need to find out the scale factor of the horizontal distance.
We write this as ratio
Mirror to Michelle : Mirror to Flagpole
12ft : 48ft
1 : 4

So the ratio of the height is
Michelle : Flagpole
1 : 4
5ft : 20ft
