So increased weight = 92-80 = 12
so ℅ = 12×100/80 = 15
so his weight is increased by 15℅ !!
Answer:
v = 0
Step-by-step explanation:
12 = 12 + v / 8
0 = 1/8v
v = 0
The equation of a circle with center at (h,k) is
(x-h)^2+(y-k)^2=radius^2
given
(x-(-1))^2+(y-3)^2=9
center is (-1,3)
first option
The simplified expression by rationalizing the denominator is (C)
.First we must simplify the expression:

Then we factor the rational parts and cancel it out:

Then we rationalize the expression:
