The starting value is 20,300, and the value is decreasing by 9.5% each year.

Because it decreases by 9.5% each year based on the previous amount, we use an exponential decay model.

A decrease by 9.5% corresponds to multiplying by 91.5% each year.

We write . We plug in 11 years for t.

A(t)=23000(0.915)^{t}\\\\A(11)=23000(0.915)^{11}\\\\A(11)=7671.18

$7,671.18

Which two days had a ratio of 2:5 computers sold? Looking for brainliest.
Marianna [84]

Answer:  A. Wed to Fri

We have a bunch of natural numbers and we're told a pair is in the ratio 2:5.

For natural numbers to have this ratio, the left number will be a multiple of two and the right number will be a multiple of five.

Our only option for a multiple of 5 is 15, Friday.  So we have

2:5 = x:15

and x = 15*2/5 = 6

which was Wednesday's number.  So we get Wed:Fri=6:15=2:5.

What is the difference between a square root and dividing by 2?
Alex_Xolod [135]

Dividing by 2 is obvious. Square root is "a number which produces a specified quantity when multiplied by itself." Essentially the opposite of exponents.
