The circumference of a circle is approximately 3.14 times the length of its diameter. Which inequality can be used to find al
possible diameter lengths, d, if the circumference of a circle is more than 50 cm?
O 3.140 < 50
O 3.14d> 50
O 50d> 3.14
O 50d <3.14

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

(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.
