Answer:
the total amount of water supplier per hour to the region within a circle of radius R=110 ( that is from distance r, 0<r<110)
Step-by-step explanation:
if f(r) describes the water supplied at a distance r , the total amount supplied inside a region that goes from 0 until the circle of radius R, is the sum of all f(r) values from 0 until R, that is the integral value over these limits.
The formula deduction can be found in the attached picture
There is an "r" that multiplies e^-r as result of changing from rectangular coordinates to polar ones.(dx*dy --> r*dr*da)
Answer:
Graph 2
Step-by-step explanation:
She first increaces to it will start going up then she maintains it so it will slowly stay and then speeds up again. I can see that the graphs on this arent really good but the best answer would be the second graph since its in 3 parts and starts from zero
Answer:
<h3>The answer is option A</h3>
Step-by-step explanation:
f(x) = (x+1)³ + 4
To find f-¹(x) equate f(x) to y
That's
y = (x+1)³ + 4
Next interchange the terms x becomes y and y becomes x
That's
x = ( y+1)³ + 4
Make y the subject
(y+1)³ = x - 4
Find the cube root of both sides
That's
Send 1 to the right side of the equation
That's
So we have the final answer as

A radius perpendicular to a chord bisects the chord, so the answer is twice 4.5
Answer: C. 9
Answer:
Step-by-step explanation:
9x+5y=35
Step 1: Add -5y to both sides.
9x+5y+−5y=35+−5y
9x=−5y+35
Step 2: Divide both sides by 9.
9x9=−5y+359
x=−59y+359
Answer:
x=−59y+359
Let's solve for x.
2x+5y=0
Step 1: Add -5y to both sides.
2x+5y+−5y=0+−5y
2x=−5y
Step 2: Divide both sides by 2.
2x2=−5y2
x=−52y
Answer:
x=−52y
