Find the indicated sum.
1 answer:
Answer:
-5
Step-by-step explanation:
The starting point is at 1 and the stopping is at 5(if you want to know where to find these, look at the image attached).
For i=1, we have i-4, which would be 1 - 4, or -3.
For i=2, we have i-4, which would be 2 - 4, or -2.
For i=3, we have i-4, which would be 3 - 4, or -1.
For i=4, we have i-4, which would be 4 - 4, or 0.
For i=5, we have i-4, which would be 5 - 4, or 1.
We would add these 5 values:
-3 + (-2) + (-1) + 0 + 1
This gives us -5

Plug in 70 ft for ,
for
and solve for the volume,
. This gives,
Therefore, the volume of the quarter sphere shaped tank is
The correct answer is D.
As you can see, the exponential function grows by doubling the previous output with each increment of the input: start with 1, you double it to get 2, then you double it to get 4, 8 and so on.
On the other hand, the linear function adds 7 with each step. This means that the exponential function will eventually reach and pass the linear one, and will definitely be grater from that point on. In fact, if we continue the table, we get
and you can see how the exponential growth is much faster than the linear one.
