A surveyor in an airplane is flying toward the lake. Shw observes the angle of depression to the side of the lake are 45 degree and 32 degree. At the moment the airplane is 9750m from the near side of the lake. Find the width

about 0.75 hours

step-by-step explanation:

you have to put the graph on here with the question

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.

ƒ = 0.03b
