The exponential decay graph shows the expected depreciation for a new boat, sell g for $3500, over 10 years.
Alisiya [41]
Okay, the exponential function is
g = a^{x}
The start price of it in t=0 is 3,500, as we can see on the graph. Then, the function becomes
g = 3500^{x}
Let's see at t=2, where the price is g=2000:
2000 =  3500^{x}
Take natural logarithm:
ln 2000 = ln  3500^{x}
x*ln 3500 = ln 2000
x = \frac{ln 2000}{ln 3500} = 0.93
So, the difference between t=0 and t=2 is
x_{t=0}  -  x_{t=2}  = 1 - 0.93 = 0.07
And then we get the change of x in one year equal to 0.035.
So, the final equation is
g =  3500^{1-0.035t}
You can insert any t and see that it is correct, for example t=7

Start with y=mx+b since it is perpindicular to the slope of -3/4 the new slope is 3/4. so now we have m=4/3 next we subsitute known values in (0,-1). We multiply 0 by 3 next we have -1=0+b so be has to be -1 so your awnser is

y=4/3-1
