Facctore each
5y^2=5*y*y
80=5*2*2*2*2
lcm of those are
5
5(y^2-16)
we can factor this difference of 2 perfect squares
5(y-4)(y+4)
y+4 is the other one
so the lcm is 5y^2-80
Answer:
B
Step-by-step explanation:
sure thank you
hope it help
What you have to do is to write your equation in the following form: (x-h)^2 + (y-k)^2 = r^2 , this is the equation that represent the circle.where (h,k) represents the center and r radius.
This is just an example to solve the center and radius of a circle.
To complete the squares, here is how to do it:
x^2 + 2*4*x + 4^2 +y^2-2*3*y+3^2 - 4^2-3^2 = 0 x^2 + 8x + 16 +y^2-6y+9 - 25 = 0 (x-4)^2 +(y-3)^2 = 25
Now h = -4 k = 3 and r = 5 . Center is (-4,3) and radius r = 5.
But then you are are looking for the equation that represent the circle describe. The answer is C. (x – 4)2 + (y – 3)2 = 2²
Answer:
The volume of the cylinder is 163.3 m³.
Step-by-step explanation:
Given that,
Height = 13 cm
Base = 4 cm
So, radius = 2 cm
We need to calculate the volume of the cylinder
Using formula of cylinder
Where, r = radius
h = height
Put the value into the formula
Hence, The volume of the cylinder is 163.3 cm³.
