Mathematics

4 0

Answer:

5 inches

Step-by-step explanation:

Since the length of the sides of a cube are all equal,

volume of cube

= side ×side ×side

= (side)³

125= (length of side)³

Cube root both sides:

Length of each edge

=  \sqrt[3]{125}

= 5 inches

Consider the function g(x) = sqrt(x + 4) - 6 which function has the same y-intercept as this function?
Inga [223]

Answer:

a)

f(x) = \frac{4}{x-8} - 3.5

Step-by-step explanation:

The y intercept of g(x) is the value of g when x = 0.

In this problem

g(x) = \sqrt{x+4} - 6

The y-intercept is

g(0) = \sqrt{0+4} = \sqrt{4} - 6 = 2 - 6 = -4

a)

f(x) = \frac{4}{x-8} - 3.5

The y-intercept is:

f(0) = \frac{4}{0-8} - 3.5 = -0.5 - 3.5 = -4

This is the correct answer

b)

f(x) = -\frac{4}{x} - 1

The y-intercept is

f(0) = -\frac{4}{0} - 1

This is an asymptote

c)

f(x) = 2|x+2|

The y-intercept is

f(0) = 2|0+2| = 4

d)

f(x) = |x - 4|

The y-intercept is

[tex]f(0) = |0-4| = |-4| = 4.
