1) The world population in 2000 was approximately 6.08 billion. The annual rate of increase
was about 1.26%. Write and graph an exponential equation to represent this situation. What is
the prediction for the population in the year 2015? If the actual population is 7.347 billion in 2015,
was the growth consistent? What was the actual percent growth from 2000 to 2015?

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
