If f(x) = √x and g(x) = 7x + b, then

f(g(x)) = f(7x + b) = √(7x + b)

If the plot of f(g(x)) passes through (4, 6), then

f(g(4)) = √(7•4 + b) = √(28 + b) = 6

Solve for b :

√(28 + b) = 6

(√(28 + b))² = 6²

28 + b = 36

b = 36 - 28

b = 8

How do u find the density of a sphere

Sliva [168]

Answer: To compute the density of a spherical object, you must weigh it. Then you divide its mass by its volume to get its density. Keep in mind that an object's density has nothing to do with its size.

Step-by-step explanation:

1. σ is the density of the sphere.

2. M is the mass of the sphere.

3. r is the radius of the sphere.
