convergent is |r|>1
so the answer would have to be less that 1.
answer is A.
From the second equation y=-1-x so we can write -2x²+3x-1=-1-x.
So -2x²+4x=0, 2x(-x+2)=0, therefore x=0 or 2 and the corresponding y values are -1 and -3.
We can write the answers as ordered pairs (0,-1) and (2,-3).
The solution to the problem is as follows:
<span>We use proportion :
Let the height of building = x ft.
We get x/21 = 15/6
x = 15*21 /6
x = 52.5 ft.
height of bldg = 52.5 ft
