Answer:

$16,748

Step-by-step explanation:

we know that

The equation of a exponential decay function is equal to

y=a(1-r)^x

where

y is the value of the car

x is the number of years

a is the initial value

r is the rate of change

In this problem we have

a=\$25,000\\r=12.5\%=12.5/100=0.125

substitute

y=25,000(1-0.125)^x

y=25,000(0.875)^x

For x=3 years

substitute

y=25,000(0.875)^3=\$16,748

ycow [4]

Answer

The initial temperature was T = -7 degrees

Step-by-step explanation:

Let the initial temperature be T.

- The tempature was very cold

Temperarure = T

- Then it doubled

Temperature = 2T

- Then it dropped 10 degrees

Temperature = 2T - 10

- And then it increased by 40 degrees.

Temperature = 2T - 10 + 40 = 2T + 30

The tempature is now 16 degrees

Temperature = 16 degrees

2T + 30 = 16

2T = -14

T = -7 degrees

Hope this Helps!!!

Two angles are supplementary. The measure of one angle is 54 more than the measure of the other angle. What is the measure of th
il63 [147K]

Answer:

bigger angle is 117°

Step-by-step explanation:

x+x+54= 180 (when two angles are complementary it means that their sum is 180 degrees)

2x+54=180

2x= 180-54

2x=128

x=126/2

x= 63

x1= smaller angle

x1= 63

x2= bigger angle

x2= 63+54

x2=117
