Answer:
f(1) = 81
Step-by-step explanation:
given is f(n + 1) = 1/3f(n)
f(3) = 9
ayou need to find f(0) before you can answer what is f(1).
Just start by applying for...
n=0
f(0+1) = 1/3 * f(0)
f(1) = 1/3 * f(0)
n=1
f(1+1) = 1/3 * 1/3*f(0)
f(2) = 1/9 * f(0)
n=2
f(2+1) = 1/3 * 1/9* f(0)
f(3) = 1/27 * f(0)
But it is given that f(3) = 9 so substitute this in the line above to calculate the value of f(0)....
9 = 1/27 * f(0)
Multiply left and right of the = sing by 27 gives
f(0) = 27 * 9
f(0) = 243
We already know this next line because we started with n=0
f(1) = 1/3 * f(0)
Substitute f(0) = 243 in the line above to finally calculate the value of f(1).
f(1) = 1/3 * 243
f(1) = 81
Answer:
18.4 ft per second.
Step-by-step explanation:
Bungee jumped off the Tallahatchie Bridge, which is 100 ft above the water surface.
And after 5 seconds he was at 8 ft above the water surface.
Therefore, in total 5 seconds, he descends by total ( 100 - 8 ) = 92 ft altitude.
Hence, the average rate of change of his altitude is given by
feet per seconds. (Answer)
a. At t=0, the pumpkin is 25 feet above the ground (Plug 0 into the equation and solve)
b. If you plug the equation in a graphing calculator and find the rightmost zero, you get t = 10.15 seconds.
c. The vertex (maximum point) of the graph is (5, 425). Therefore, the pumpkin reaches its maximum height of 425 feet after 5 seconds in the air.
