Answer:
Ariah needs 2748 kilograms of air to fill the balloon.
Step-by-step explanation:
The coordinates are plotted and connected from one point to the other to see the triangle form. At first, it looks like an isosceles triangle, but after getting the distances, it is a SCALENE triangle.
Let 1993 = time 0 = 0.
Let 1999 = time 6 = 6
Let 2012 = time 19 = 19
So, a = 171 (million). First solve for k.
176 = 171 e^k6
176/171 = e^(k*6)
ln (176/171) = 6k
k = 1/6 ln (176/171)
So, in 2012 we have: P(19) = 171 e^(19k), where k = 1/6 ln (176/171)
Hope this helped!
