R = Diameter / 2

R = 290/2

R = 145 ft

Complete the square to solve<br>f(x)=x^2+6x-7​
antoniya [11.8K]

Answer: x = 1 and x = -7

Explanation:
x^2 + 6x - 7 = 0
x^2 + 6x + 3^2 = 7 + 3^2
(x + 3)^2 = 16
x + 3 = +-4 (square both sides)

x + 3 = 4
x = 1

x + 3 = -4
x = -7

Find f(x) and g(x) so that the function can be described as y = f(g(x)).
kompoz [17]

Answer:

The fourth option gives the result.

Step-by-step explanation:

We have to find f(x) and g(x) from options given such that y = f[g(x)] is equivalent to y = \frac{8}{\sqrt{2x + 4}}.

Here, the fourth option gives the result.

If f(x) = \frac{8}{\sqrt{x} } and g(x) = 2x + 4, then the composite function f[g(x)] = \frac{8}{\sqrt{2x + 4}}

⇒ y = \frac{8}{\sqrt{2x + 4}} ( Answer )
