From the points you get a slope of -1 using the slope in y=mx+b you get b=1 so y=-x+1
use the Pythagoras theorem method
a squared plus b squared equals c square
The answer would be c because the absolute value of both numbers would be the distance between them
Sin^(1/2) x cos x - sin^(5/2) cos x
= sin^(1/2) x cos x - sin(1/2)x sin^2 x cos x
factoring we get:
cos x sin^(1/2) x ( 1 - sin^2 x)
Now 1 - sin^2 x = cos^2 x so we have
cos x sin^(1/2) x * cos^2 x
= cos^3 x sqrt sin x
Answer:
8.3 L/s
Step-by-step explanation:
To find the answer you need to find the slope also known as the rate of change. When you find slope it is always change in y over change in x.

Then simplify

Then divide to get your slope/average rate of change
= 8.3
