Answer: C(t) = 28000(0.811)^t
Step-by-step explanation:
it begins to depreciate at a rate of 18.9% annually. This means that the rate at which the value is decreasing is exponential. We would apply the formula for exponential growth which is expressed as
y = b(1 - r)^ t
Where
y represents the value of the car after t years.
t represents the number of years.
b represents the initial value of the car.
r represents rate of depreciation.
From the information given,
P = 28000
r = 18.9% = 18.9/100 = 0.189
Therefore
y = 28000(1 - 0.189)^t
y = 28000(0.811)^t
Where C(t) represents y, the function becomes
C(t) = 28000(0.811)^t
Just switch ur x's and y's
(5,1), (6,2) , (7,1), (8,4) <== the inverse
Tan(angle) = Opposite Leg / adjacent leg
tan(37) = x / 10
x = 10 *tan(37)
x = 7.5
Exact form: (8.3+6.3)^2-66.138
Decimal Form: 147.022
I don't really think that this is the answer to what you're looking for but I do think you made an error on your question.
Answer:
answers!
for the problem: 36 + 8 = 44 (keep in mind)
Step-by-step explanation:
1st one: 4 × (9 + 2) = 54
9 + 2 = 11
4 x 11 = 44
2nd: 4 x 11 = 44
