Answer:
Average speed is 3 kilometers an hour
Look up what is mean and calculate it.
Answer:
V'(t) = ![-250(1 - \frac{1}{40}t)](https://tex.z-dn.net/?f=-250%281%20-%20%5Cfrac%7B1%7D%7B40%7Dt%29)
If we know the time, we can plug in the value for "t" in the above derivative and find how much water drained for the given point of t.
Step-by-step explanation:
Given:
V =
, where 0≤t≤40.
Here we have to find the derivative with respect to "t"
We have to use the chain rule to find the derivative.
V'(t) = ![2(5000)(1 - \frac{1}{40} t)d/dt (1 - \frac{1}{40}t )](https://tex.z-dn.net/?f=2%285000%29%281%20-%20%5Cfrac%7B1%7D%7B40%7D%20t%29d%2Fdt%20%281%20-%20%5Cfrac%7B1%7D%7B40%7Dt%20%29)
V'(t) = ![2(5000)(1 - \frac{1}{40} t)(-\frac{1}{40} )](https://tex.z-dn.net/?f=2%285000%29%281%20-%20%5Cfrac%7B1%7D%7B40%7D%20t%29%28-%5Cfrac%7B1%7D%7B40%7D%20%29)
When we simplify the above, we get
V'(t) = ![-250(1 - \frac{1}{40}t)](https://tex.z-dn.net/?f=-250%281%20-%20%5Cfrac%7B1%7D%7B40%7Dt%29)
If we know the time, we can plug in the value for "t" and find how much water drained for the given point of t.

Answer:
and ![[6,9,8,7]](https://tex.z-dn.net/?f=%5B6%2C9%2C8%2C7%5D)
Step-by-step explanation:
GIVEN: an array of ten integers
.
TO FIND: If we partition this array using Quick sort's partition function and using
for the pivot. List the elements of the resulting array after the partition finishes.
SOLUTION:
quick sort is a divide and conquer algorithm in which an array is partitioned into sub-arrays about an pivot element by checking whether elements are greater than pivot or and then sub arrays are sorted recursively.
Here
is the pivot element.
two arrays will be created, in first array element less than or equal to pivot element are stored in other elements greater than pivot element are stored.
Starting from first element of array
elements in first array will be ![=[4,0,3,1,2,5]](https://tex.z-dn.net/?f=%3D%5B4%2C0%2C3%2C1%2C2%2C5%5D)
elements in second array will be ![=[6,9,8,7]](https://tex.z-dn.net/?f=%3D%5B6%2C9%2C8%2C7%5D)
Hence the resulting array after the partition finishes are
and ![[6,9,8,7]](https://tex.z-dn.net/?f=%5B6%2C9%2C8%2C7%5D)
