The correct answer to this question is "<span>7 times square root of 74 over 74."</span>

First, we need to get for the "r."
<span><span>r^2 </span>= (−5<span>)^2 </span>+ <span>7^2
r^2 = 25 + 49
r^2 = 74
r = square root of 74

Then, after that, we need to formulate the equation of a sin:
sin x = 7 / r
sin x = 7 / sqrt(74)
sin x = 7 * sqrt (74) / 74</span></span>

Julli [10]

Answer:

y=45000(1-0.03)^x

Step-by-step explanation:

1) the exponential decay formula is

y=c(1-r)^x

where c= starting amount

r=rate of change

x=time

so

y=45000(1-0.03)^x

y=45000-1350x
