Problem 4 An exponential function is defined by k(20) = 15.2.
1. Show that when x increases from 1 to 1.25 and when it increases from 2.75 to 3, the value of k
grows by the same factor.
2. Show that when x increases from t tot +0.25, k(t) also grows by this same factor.
(From Unit 4 Lesson 5)

first one is a: renaming a fraction. second one is c: de-c

ez do it yourself lazy

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

the correct option is b
