domain refers to the X values so option A would be correct :)
X=45y
x is distance and y is the time the car goes 45 miles per hour so distance equals 45 times time
Answer:
18x² + 5
Step-by-step explanation:
To evaluate f(g(x)), substitute x = g(x) into f(x)
f(g(x))
= f(6x²)
= 3(6x²) + 5
= 18x² + 5
Answer:
x = 18
18√2
Step-by-step explanation:
This is a special right triangle with angle measures 45° 45° 90°
in this special triangle the side lengths are expressed as a, a, and a√2
So x = a and x = 18
r = a√2 and r = 18√2
