Study the work shown below and compare the results to the product of –2i(6 – 7i).
(0 – 2i)(6 – 7i)
= (0)(6) + (0)(–7i) + (–2i)(6) + (–2i)(–7i)
= 0 + 0 –12i + 14i2
= –12i – 14
= –14 –12i
the products are
.

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

okay..i will pick 8!

(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.
