Answer 1

Answer:

• C. (f • g)(2) = 44, the distance in miles the boat traveled

Step-by-step explanation:

Given functions:

• f(x) = 2x² + 3
• g(x) = x + 2

Find the value of (f · g)(2):

• (f · g)(2) = f(2) · g(2) = (2(2²) + 3) · (2 + 2) = 11 · 4 = 44

Since this is a product of the speed and the time, this represents the distance travelled in 2 hours

Correct choice is C

Answer 2

Answer:

The distance traveled by the B737-400 aircraft in 5 hours is 2,000 miles

Step-by-step explanation:

Average speed = 400 miles per hour

Distance = 400t

t= 5

Total distance = 400t at t hours

Total distance when t = 5 hours

Total distance traveled = 400t

= 400 × 5

= 2,000 miles

Total distance travelled = 2,000 miles

The distance traveled by the B737-400 aircraft in 5 hours is 2,000 miles

hope this helps
