Given:-

To find:-
The simplified form.
At first we take conjucate and multiply below and above.
The conjucate is,

So now we multiply. we get,

Now we simplify. so we get,

We know the value of,

Substituting the value -1. we get,

So now we split the term to bring it into the form a+ib. so we get,

So the required solution is,
Answer:
5cm
Step-by-step explanation:
Given data
volume = 225π cm³
Height= 9cm
r= ???
Volume of cylinder
v=πr^2h
substitute
225π= π*r^2*9
225= r^2*9
r^2= 225/9
r^2= 25
r= √25
r= 5cm
Hence the radius is 5cm
Answer:
y = 0
Step-by-step explanation:
y = mx + c
M is taken as gradient.
Gradient is equals y difference ÷ x
difference
Y difference = 0
X difference = 0 - (-3) = 3
Hence the gradient here is 0
Let us take the co ordinates (0,0) (you can take any of the coordinates given)
Substitute the equation:
y = mx + c
0 = 0×0 + c
C = 0
Hence y = 0 is the answer
So hence the values of y co ordinates lie on 0
I hope this was the right answer and it helped you
