53. every year, mikhail receives a 3% raise in his annual salary. his starting annual salary was $40,000.
a. does a geometric or arithmetic sequence best model mikhail’s salary in yearn? explain how you know.

Geometric sequence.

Step-by-step explanation:

In this situation Mikhail's salary increases by a constant multiple each year. A 3% rate is equivalent to multiplying the previous salary by a constant of 1.03, Mikhail's salary can be modeled by the following recursive equation:

.

Therefore, since the same multiple can be used to find the next term in the sequence, a geometric sequence best models his salary.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

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
