The depreciating value of a semi-truck can be modeled by y = Ao(0.85)x, where y is the remaining value of the semi, x is the tim

e in years, and it depreciates at 15% per year. An exponential function comes down from the positive infinity and passes through the points zero comma seventy-five thousand. The graph is approaching the x-axis. What is the value of the truck initially, Ao, and how would the graph change if the initial value was only $65,000?

Answer:

Step-by-step explanation:

Given that the  depreciating value of a semi-truck can be modeled by

y = Ao(0.85)^x

Since it crosses (0,75000) we find that when x =0 y = 75000

Substitute to get

A_0 = 75000

So equation would be

y = 75000(0.85)^x

If initial value is changed to 65000, the y intercept would be shifted down to

65000.  The whole curve would be a bit vertical down than the previous curve.

We are given the equation
y = Ao (0.85)^x

Initially, at x = 0, the value of y is
y = Ao (0.85)^0
y = Ao

If the initial value was $65,000 at the same rate of depreciation, the equation would be
y = 65000 (0.85)^x

Kelly uses cruise control to drive at a constant speed. She travels first 192 miles in 3 hours. At the rate, how long will it ta
ioda

Answer:

Step-by-step explanation:

rate = d / t

rate = 192 / 3

rate = 64 miles / hour

Now you want to know how long it can take to get 448 miles

d = r * t

t = d / r

t = 448/64

t = 7 hours.

You could actually do it using proportions.

192/3 = 448/x                   Cross multiply

192*x = 448*3

192*x = 1344                    Divide by 192

x = 1344/192

x = 7

Do this the way you feel is the best way.
