Answer:
We'll use 3.14 as an approximation of pi. So, now we plug the values into the equation. A = 3.14 * 8^2/2.
Step-by-step explanation:
(a) (b) The integral
gives the total amount of water removed.
This is an overestimate since we are using a left Riemann sum on a decreasing function R.
(c) The integral
gives the total amount of water added at the end of 8 hours.
(d) If we have the equation
, then
.
Let
. Then
is continuous as it is a difference of two continuous functions (R(t) being differentiable implies continuity).
We have
.
Therefore, Intermediate Value Theorem says that there is a time
for which
. At this value of
, the rate of water being pumped into the tank will be equal to the rate of water removed.
The current value of the precious metal is $144/oz
-First, you'd want to determine the original value per ounce since that's what the final unit being asked for is.
- Since the original value of the half ounce piece is given, this first step is fairly simple. You just double ninety.
- We now know that the metal was worth $180/oz when the museum first received it.
- We need to determine the current price of the metal now that is has had a twenty percent loss of value.
- My favorite way to factor in 20% is simply to divide by five since it's a lot more simple than finding the ratio of x$/1%
- $180/5=$36
- Thirty-six dollars is the price drop over the course of the museum possessing the precious metal.
- You now take $180-$36=$144
Answer:
32=x+2x+4x
32=7x
x=4.571428571428571428
and,2x=9.142857142857142857
and,4x=18.28571428571428571
