Mario bought a new car for $25,000. The value of the car is decreasing at a rate of 12.5% every year. After 3
maxonik [38]

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

Responda: Por favor, é urgente.
kumpel [21]

Answer:

C) CA=40

Step-by-step explanation:

2y/(2y+4)=(2y+6)/4y

cross multiply

8y²=4y²+20y+24

4(2y²)=4(y²+5y+6)

divide both sides by 4

2y²=y²+5y+6

y²-5y-6=0

(y-6)(y+1)=0

So the answer must be either 6 or -1.  Since it can't be a negative number, it must be 6.

CA=2(6)+4+4(6)

CA=12+4+24

CA=40

Lines AB and CD are parallel. If 1 measures (2x + 15)°, and 4 measures 101°, what is the value of x?
Sloan [31]

Answer:

x = 32°

Step-by-step explanation:

Given:

Line AB║CD

Angle 1 = (2x + 15)°

Angle 4 = 101°

Find:

Value of x = ?

Computation:

We know that Angle 1 and Angle 4 stay on same line , so Angle 1 and Angle 4 are liner pair.

∴ Angle 1 and Angle 4 = 180°

⇒ (2x + 15)° + 101° = 180°

⇒ 2x + 116° = 180°

⇒ 2x = 180° - 116°

⇒ 2x = 64°

⇒ x = 32°

Therefore value of x 32°
