Answer:
18
Step-by-step explanation:
f(x) = 2x^2
Let x = -3
f(-3) = 2 * (-3)^2
Exponents first
f(-3)=2 *9
f(3) = 18

Answer: The answer is A.
Step-by-step explanation:
The time taken to get to work from home with a speed of 30mph will be 40 minutes, 40mph in 30 minutes, and 50mph in 24 minutes.
<h3>What is velocity?</h3>
Velocity is the rate of distance covered per time. Velocity could be average or instantaneous.
Average velocity can be given as;
Average velocity = total distance / total time taken
Units of velocity are given by ⇒ meter/second
As per the given,
Time = distance/speed
Distance = 20 miles
With a speed of 30 mph
Time = 20/30 = 2/3 hour or 40 minutes
With a speed of 40 mph
Time = 20/40 = 1/2 hour or 30 minutes
With a speed of 50 mph
Time = 20/50 = 2/5 hour or 24 minutes
Hence "The time taken to get to work from home with a speed of 30mph will be 40 minutes, 40mph in 30 minutes, and 50mph in 24 minutes".
