Estimate the time it would take you to drive 361 miles at 42 miles per hour. Round to the nearest hour.
polet [3.4K]

Answer:

It would take you 9 hours

Step-by-step explanation:

Speed (s) = Distance (d) / Time (t)

given that; Speed = 42 miles/hour

                 Distance = 361 miles

42 miles/hour = 361 miles / Time (t)

Time (t) * 42 miles/hour = 361 miles

Time (t) = 361 miles / 42 miles/hour

Time (t) = 8.59 hours

             ≈ 9 hours (to the nearest hour)

If f(x) = x2 – 1 and g(x) = 2x – 3, what is the domain of (f*g)(x)?
leva [86]

(f.g)(x) =( f(x))(g(x)) \\  = ( {x}^{2}  - 1)(2x - 3) \\  = (x - 1)(x + 1)(2x - 3)
then the domain of (f•g)(x) is {-1, 1, 3/2}
