D) The following steps show how the equation for the average rate can be transformed so that it is written in terms of only the rates for each leg of the trip. Write an algebraic justification for each step. Think about the number operations and properties that you know.
Sum of fractions in the denominator making cross product:
d / r1 + d / r2
Resulting:
d * r2 + d * r1 / (r1 * r2)
Multiply numerator and denominator by the following expression:
(r1 * r2) / (d * r2 + d * r1)
Take common factor in the denominator of the expression in step 2.
Resulting:
(d * r2 + d * r1) = d * (r2 + r1)
e) Using the equation for average rate above, determine the cheetah’s average rate for the entire trip.

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)
