The equation to model Exponential Growth is:
abruzzese [7]

Your salary in x years is modeled an the exponential growth

The equation that determines your salary in x years is y = 45000(1.05)^x

<h3>How to model the salary growth?</h3>

The model of the exponential growth is given as:

y = a(1 + r)^x

From the question, we have:

Initial salary, a = 45000

Raise, r = 5%

So, the equation becomes

y = 45000(1 + 5%)^x

Evaluate the sum

y = 45000(1.05)^x

Hence, the equation that determines your salary in x years is y = 45000(1.05)^x

A giraffe can run up to 46.93 feet per second. how far could a giraffe run in 1.8 seconds?
shepuryov [24]
Well, we know that distance equals speed x time. If the giraffe can run 46.93 feet per second, then by using our equations, we can deduce that the giraffe can run 84.474 feet within 1.8 seconds.
