Answer:

$113,140.821

Step-by-step explanation:

The growth of an investment is given by $P(1+r)^{n}$ where P is the principal, r is the interest rate, and n is the number of periods. So

$Future value = 100,000 ( 1+0.025)^{5}$

Future value=$113,140.821 as the amount after 5 years.

A square and a rectangle have the same perimeter. The square has a side length of 8x units. The rectangle has a length of (5x+8)

nevsk [136]

Answer:

The perimeter of both figures is equal to $64\ units$

Step-by-step explanation:

step 1

we know that

The perimeter of a square is equal to

$P=4b$

where

b is the side length of the square

we have

$b=8x\ units$

substitute

$P=4(8x)=32x\ units$

step 2

we know that

The perimeter of a rectangle is equal to

$P=2(L+W)$

we have

$L=(5x+8)\ units$

$W=(14)\ units$

substitute

$P=2(5x+8+14)=10x+44\ units$

step 3

Equate both perimeters and solve for x

$10x+44=32x$

$32x-10x=44$

$22x=44$

$x=2\ units$

step 4

Find the perimeter of both

square

$P=32x=32(2)=64\ units$

rectangle

$P=10x+44=10(2)+44=64\ units$

Find the mean of the data in the dot plot below

Firdavs [7]

The mean would be 5
Reason for this is that the mean is when all data is summed up then divided by how many data points there are
So 4+4+7=15
Then divide by 3 would equal 5
I hope this helps!
