Answer:825000
Step-by-step explanation:
Answer:
3.05
Step-by-step explanation:
T = k/R where k is the constant of variation, T=time and R=speed.
Plug in the given values:-
12 = k/60
k = 12*60 = 720
So the equation of variation is T = 720/R
At 85 mph we have
T = 720 / 85 = 8.47 hours (answer)
Answer:
The value of f(3) = 13
Step-by-step explanation:
It is given that a function f(x),
f(x) = 2x²/2 + 4
<u>To find the value f(3)</u>
For that we have to substitute 3 instead of x
f(x) = 2x²/2 + 4
f(3) = 2 * (3)²/2 + 4
= (2 * 9/2 )+ 4 = 13
Therefore the value of f(3) = 13
