Select the correct answer. Consider functions fand g.
f(x) = x2 + 73
= 31 - 1
What is the value of (f. og)(x);
A.
9.x2 + 151 - 6
OB. 312 + 7x - 1
O C. 3.x2 + 213 + 1
OD. 9x2 + 213 – 1

answer: graph 2

step-by-step explanation:

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

the answer is  

d.

121π mi^2

hope you got it chief
