Erin and her friends are taking a road trip. she has agreed to drive between hours 3 and 6 of the trip. if h represents the hours of the trip erin will be driving, then h ? 3 and h? 6 represents her portion of the driving. while she is driving, her distance and time are modeled by the inequality d < 70h. what are the possible hours and distances erin could be driving?

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
