O A.
neither a relation nor a function
OB.

OC.
function only
OD.
relation only

(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.

b

step-by-step explanation:

this is because the profit is decreasing and turning into debt

the translated point is (5,2)

step-by-step explanation:

tangent z: 4/3

cosine y: 4/5

cotangent y: 4/3
