Answer:
let the time be "x" minutes for both
after x minutes,
the first pool will have 1660l + 30.75x
and the second pool will have 1900+ 23.25x
note: both pool Will have equal volume of water
1660+ 30.75x=1900+23.25x
30.75x-23.25x= 1900-1660
7.5x=240
x = 240/7.5
x= 40minutes
Step-by-step explanation:
First find the gradient. Then, find out the y-intercept then substitute into y=mx+c
X = 25
a^2 + b^2 = c^2
19^2 +16^ = c^2
617 = c^2
(Square root 617)
x=24.83
x=25
When you are doing derivatives, you don't want to do it right away because there is still ( ) we need to remove that first get,
g(x)=3x^4-6x
Now we can do the derivatives!
g(x)=12*x^3 - 6
I hope this helps!
The new perimeter would be 60. because the width and the height are doubled.
