ElenaW [278]

Answer:

a) In the first season, there were 25.450 million viewers.

b) In the fourth season, the number of viewers was 11.950 million.

Step-by-step explanation:

Hi there!

The average number of viewers in season t is given by the following function:

f(t) = 32.744 e^{-0.252t}

a) To obtain the average number of viewers in season 1, we have to evaluate the function at t = 1:

f(1) = 32.744e^{-0.252 (1)} = 25.450

In the first season, there were 25.450 million viewers.

b) Now we have to evaluate the function at t = 4:

f(4) = 32.744e^{-0.252(4)} = 11.950

In the fourth season, the number of viewers was 11.950 million.

Calculate the average speed of a complete round trip in which the outgoing 300 km is covered at 97 km/h, followed by a 1.0-h lun
gizmo_the_mogwai [7]

Answer:

Average Speed  is 65 km/hr

Step-by-step explanation:

To get the average speed,  first we have to calculate the time spent in the round trip .

Speed= Distance/ time

So,  Time= Distance/Speed

Time Outgoing= 300km/ 97km/hr

Time Outgoing=3.0927 hr

Time lunch break =1 hr

Time return= 300km/ 58km/hr

Time Outgoing=5.1724 hr

Total= 3.0927 hr+1 hr+5.1724 hr=9.2651

To get average speed,  we have to divide all the distance by the time it took al the trip.

Average Speed= Distance/ time

Average Speed= 600km/9.2651 hr= 64,76 km/hr

Average Speed=64,76 km/hr ≅ 65km/hr
