20% have an A because 1/5 of 100 is 20
Answer:
A=640.88
Step-by-step explanation:
if the diameter is 12, the radius , r=12/2=6
we have r=6, h=11
Surface area, A= 2πrh+2π r^2
A=2*3.14*6*11+2*3.14*(6)^2=640.88
A polynomial function with all even exponents is so-called even function.
Even functions are symmetric across the y-axis.
Answer: Only one that is symmetric across the x-axis is the function C ).
Answer:
(x-4)^2 / 16 + (y+2)^2 / 7 = 1 or 7x^2-56x+16y^2+64y+64=0
Step-by-step explanation:
Either one should be right I think. Hope this helps.
No, it is not a function because that is for any y single value.
