900,000,000. move the decimal until you have a number between 1-10 so move it 8 times and you'll have 9×10^8
Answer:

Step-by-step explanation:
Evaluate g(- 4) and f(- 4) by substituting x = - 4 into g(x) and f(x), that is
f(- 4) = - 10(- 4) + 9 = 40 + 9 = 49
g(- 4) = (- 4)² + 12 = 16 + 12 = 28
Then
=
= 
Answer:
Sin = PQ / PR = OPPOSITE / HYPOTENUSE

Answer:
D) 32.5 ft
Step-by-step explanation:
Here we have to use the trigonometric ratio.
We need to find the length of the hypotenuse.
We use sin ratio.
Sin 38 = Opposite / Hypotenuse
Here opposite = 20, Hypotenuse = Length of the six cars
sin 38 = 20 / length of the six cars
The length of six cars = 20 / sin 38
The length of the six cars = 32.48
Which is closest to 32.5 ft
Thank you.
