Your bike was originally purchased for $1,200. It loses about 8% of its original value each year. Write an equation to represent
Arlecino [84]

Answer:

y= 1200(0.92)^x

Step-by-step explanation:

Given data

Cost price= $1200

Rate of decrease= 8%

Let the time be x

The expression that describes an exponential function is

y= ab^x

for decrease b= 1-r

y= 1200(1-0.08)^x

y= 1200(0.92)^x

Hence the expression is

y= 1200(0.92)^x

The perimeter of a backyard basketball court with four sides is 90 feet. Two sides of the court are each 20 feet long. One side
Alex787 [66]

Given:

The perimeter of a backyard basketball court with four sides is 90 feet.

Two sides of the court are each 20 feet long.

One side of the court is 25 feet long.

To find:

The missing side length of the basketball court.

Solution:

Let x be the missing side length.

The three given sides of the basketball court  are 20 feet, 20 feet, 25 feet.

We know that the perimeter is the sum of all sides.

Perimeter=x+20+20+25

Perimeter=x+65

The perimeter of a backyard basketball court with four sides is 90 feet.

x+65=90

x=90-65

x=25

Therefore, the missing side length is 25 feet and the correct option is B.

<u>Answer:</u>

$593.26

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

We know that the price of the laptop is $2500 and each year its resale value decreases by 25%. It means that 100 - 25 = 75% of the value is retained every year for the resale.

So, the resale value for 1st year = \frac{75}{100} *2500 = $1875

for 2nd year =  \frac{75}{100} *1875 = $1406.25

for 3rd year =  \frac{75}{100} *1406.25 = $1054.7

for 4th year =  \frac{75}{100} *1054.7 = $791.01

for 5th year =  \frac{75}{100} *791.01 = $593.25

Or we can use the following formula to find its resale value after 5 years:

2500*(0.75)^5 = $593.26
