A scientist wants to find the radius, in feet, of this hemispherical dome. He found that the surface area of the entire sphere c

skelet666 [1.2K]

The surface area of a sphere by definition is given by:
A = 4 * π * r ^ 2
Where,
r: radius of the sphere.
Substituting the values we have:
294 = 4 * π * r ^ 2
We cleared the radio:
r ^ 2 = (294) / (4 * π)
Answer:
An equation that I could use to find the dome's radius is:
A. r2 = 294 square feet ÷ 4π

Identify the effect on the graph of replacing f(x) by A f(x)

JulijaS [17]

Answer:

See explanation

Step-by-step explanation:

Required

Effect of replacing $f(x)$ with $f(x - h)$

f(x) is represented as: (x,y)

While

f(x - h) is represented as (x - h, y)

Notice the difference in both is that, the x value in f(x - h) is reduced by a constant h while the y value remain unchanged.

This means that the graph of f(x) will shift horizontally (i.e. along the x-axis) to the left by h units
