Answer:
y = 5 e^r * t
Let y be the population in billions and t the value of elapsed years
7 = 5 e^r * t is the equation being used where t = 15
7/5 = e^r * t
ln 7/5 = r * t taking ln of both sides
r = .336 / 15 = .0224
y = 5 e^(.0224 t) is then our equation
Check - suppose you want y at 2020
y = 5 e^(.0224 * 20) would be the equation
y = 5 e^.449 = 7.83 billion - seems to be a reasonable answer

Answer: x=8
How: 41 the triangles are mirrored, so they have the same angles. You are trying to find the bottom angle of the top triangle, which is the same as the top angle of the bottom triangle since they are mirrored. So, (5x+1) is equal to 41. 41-1 =40. 40/5=8. Boom.
