1. describe two ways the numbers in each proportion are related.
a) 5: 20 = 125: 500 b) 10: 1 = 120: 12 c) 75: 25 = 300: 100
d) 1: 3 = 16: 48
2. multiply between ratios to determine each value of n.
a) 2: 5 = 8: 0 b) 2: n = 6: 9 c) n: 5 = 12: 20
d) 8: n = 4: 15

3. multiply within ratios to determine each value of z.
a) 4: 8 = 3: 7 b) 5: 2 = 6: 18 c) z: 14 = 10: 20
d) 3: 21 = 7: 56

answer: i think one of the answer is $150 and $300?

step-by-step explanation:

2,160 π

step-by-step explanation:

(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.
