Mariah opens a savings account to save money for a new car. The value of her savings account can be modeled by the function y=2,000(1.065)x, where y is the value of the account, and x in the number of months since opening the account. what is the rate of growth(interest rate) that Mariah's account is receiving A. 65%
B.0.65%
C.6.5%
D.165%

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

y-y1=m(x-x1)

y-1=1(x-8)
