84 square feet I just took the test and got it right! :)
F = 42 revolutions / 60 s = 0.7 Hz
<span>Omega = 2 * pi * F = 4.4 rad/s
hope this helps!</span>
Answer:
25. 50 percent of 50 is 25 divided by 2.
Using translation concepts, it is found that the function graphed is defined by:
D. y = |x - 2| + 3.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the function has the format of the absolute value function, y = |x|, which has vertex at (0,0). Here, the vertex is at (2,3), that is, the function was shifted:
- 2 units to the right, that is, x -> x + 2.
- 3 units up, that is, y -> y + 3.
Hence the definition is given by:
D. y = |x - 2| + 3.

Answer:
Step-by-step explanation:
The formula for determining the surface area of a sphere is expressed as
Surface area = 4πr^2
Where
r represents the radius of the sphere
π is a constant whose value is 3.14
From the information given,
Surface area of the sphere = 100 centimeters ^2. Therefore,
100 = 4 × 3.14 × r^2
100 = 12.65r^2
r^2 = 100/12.65 = 7.9051
r = √7.9051
r = 2.81 centimeters
