Answer: 165

Step-by-step explanation:

Exponential equation for decay :A= P(1-r)^t , where A is the value after t year, P = initial value.

As per given ,

P= 2378

t= 20 years

r = 12.5% = 0.125

Now ,

A=2378(1-0.125)^{20}\\\\=2378(0.875)^{20}\\\\= 2378(0.0692087587)\\\\=164.57842\approx 165

Hence, the population of the town in 2015 = 165

I REALLY DONT GET THIS PLEASE HELP AND EXPLAIN!:)
Svetradugi [14.3K]
So for perimeter you need to find out the total of all the sides. To find out side AB, you make a triangle and find out the hypotenuse.

a=5 and b=6
a square= 25 b square= 36
25+36= 61
Square root of 61 is 7.81

So side AB is 7.81 ft

Now we need to find out side BC.

a=3 and b=4
a square is 9 and b square is 16.
9+16 is 25
Square root of 25 is 5

Side BC is 5 ft.

Because it's a rectangle, side CD will be 7.81 and side DA will be 5.

7.81*2+5*2= 25.62 ft

So the perimeter of the rectangle is 25.62 ft or C.

What is the solution set for |x/2|=8
Ksenya-84 [330]

<u>Answer:</u>

The correct answer option is x = -16 and x = 16.

<u>Step-by-step explanation:</u>

We are given the following equation and we are to find the solution for this equation:

| \frac { x } { 2 } | = 8

For the given equation, involving the modulus, we will have a positive as well as a negative value for it in order to find its solution set.

\frac { x } { 2 } = - 8 and \frac { x } { 2 } = 8

x = 8 \times 2 and x = - 8 \times 2

x = -16 and x = 16
