Given the following functions f(x) and g(x), solve f over g (−5) and select the correct answer below:f(x) = 2x − 20g(x) = x − 1a

timama [110]

Answer:

(f/g)(-5) = 5

Step-by-step explanation:

You mean, "determine the value of (f/g)(x) at x = -5."

That would be:

f(x) 2x - 20

------- = ------------ and we now substitute -5 for x:

g(x) x - 1

2(-5) - 20 -30

(f/g)(-5) = --------------- = -------- = 5

-5 -1 -6

A city planner wants to build a ramp onto a highway. The vertical distance that the ramp goes up is 160ft. The length of the ram

Dimas [21]

Answer:

300 ft

Step-by-step explanation:

Given that a city planner wants to build a ramp onto a highway. The vertical distance that the ramp goes up is 160ft. The length of the ramp is 340ft and represents the hypotenuse of a right triangle.

i.e. the triangle formed is a right one with hypotenuse 340 ft and one side 160ft. The other side is the horizontal distance the ramp will cover say x

Then by Pythagorean theorem we get

$340^2 = 160^2+x^2\\x^2 =(340+160)(340-160)\\\\x^2 =90000\\x =300 ft$
