Answer:
2/π ≈ 0.637 m/s
Step-by-step explanation:
The rate of change of area with respect to time is ...
A = πr²
dA/dt = 2πr·dr/dt
Filling in given values in the above equations, we can find r and dr/dt.
25π = πr² ⇒ r = 5
20 = 2π·5·dr/dt
dr/dt = 20/(10π) = 2/π . . . . meters per second
The radius is increasing at the rate of 2/π ≈ 0.637 meters per second.

Answer: √32
Step-by-step explanation: so the displacement is north 4 and west 4 and it becomes a right triangle so the hypotenuse is the distance for segment AB
So Drawn out should like straight lines up,down,left,and right. So east is positive while west is negative same for North(+) and South(-)
I recommend sticking with 2 directions first. Starting with north and south right. First you go south 1 mile but then you go north 5miles in math terms
-1+5=4 or down one is one less than 5
Same for east and west. 3+-7 = -4
So we went positive 4 miles up and 4miles to the left
So (-4)^2+4^2= hypotenuse or AB segment in this case
Answer:
Step-by-step explanation:
Percentile Formula
P = (n/N) × 100
Where,
n = ordinal rank of the given value or value below the number
N = number of values in the data set
P = percentile
Or
Percentile = (Number of Values Below “x” / Total Number of Values) × 100
