1. identify all correct answers (there may be more than one). in the expression a^b, a. the value b is an exponent. b. the value a tells you how many times to multiply b by itself. c. the value a must be > 1. d. the value b tells you how many times to multiply a by itself. e. the value b must be an integer.

multiple all that

step-by-step explanation:

27×17

(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.
