RideAnS [48]3 years ago

4 0

Answer:

x = 30

y = 2

Step-by-step explanation:

Please note: the value for x is correct only if this triangle is a right triangle.

This can be solved because 2(5y) = 20 and because if a triangle has all congruent angles then its side lengths are also congruent.

State whether the decay is linear or exponential, and answer the associated question. The value of a car is decreasing by 9% p

Sunny_sXe [5.5K]

Answer:

Exponential
A(2)=$9109.10

Step-by-step explanation:

Since the value of the car decreases by a common factor each year, the decay is exponential.

An exponential decay function is of the form

$A(t)=A_0(1-r)^t$ where:\\Initial Value, A_0=\$11,000\\$Decay Factor, r=9%=0.09$

Therefore, the function modeling the car's decay is:

$A(t)=11000(1-0.09)^t$

We want to determine the car's value in two years.

When t=2

$A(2)=11000(1-0.09)^2\\A(2)=\$9109.10$

The value of the car in 2 years will be A(t)=$9109.10
