Answer:
$16,748
Step-by-step explanation:
we know that
The equation of a exponential decay function is equal to
where
y is the value of the car
x is the number of years
a is the initial value
r is the rate of change
In this problem we have
substitute
For x=3 years
substitute
Grayson: 35h + 35 = y
Ian: 45h + 15 = y
(Substituting first hour in h)
35h + 35 = y
35(1) + 35
y = 70$ in the first hour for Grayson
45h + 15 = y
45(1) + 15
y = 60$ in the first hour for Ian
Grayson charges > Ian charges
(Substituting second hour in h)
35h + 35 = h
35(2) + 35
105$ in the second hour for Grayson
45h + 15 = h
45(2) + 15
135$ in the second hour for Ian
Grayson charges < Ian charges
Answer:
In the first hour Grayson charges more than Ian.
If you are setting it up as a proportion then you would muiltiply the 12 and x to get 12x. Then muiltiply the 80 and 1 to get 80. So 12x=80. Divide the 12 to get your final answer
Answer:
Sin (67°)
Step-by-step explanation:
