The first thing you should know for this case is how many years there are from 1997 to 2014.
The number of years is:
x = 2014-1997 = 17
Then, you must replace this value in the given equation:
y = 1.28e ^ 1.31x
y = 1.28 * e ^ (1.31 * (17))
y = 6011018736
answer:
the number of camera phones shipped in millions in 2014 is
y = 6011018736
7 because it is within a week according to my guest
You have no more money in your account, do you have insurance?
2x + 1.5x +20 = 90
3.5 x = 90-20
3.5 x = 70
x = 70/3.5
x = 20
angle DAE = 2*20 = 40
angle CAD = 1.5*20 +20 = 50
