Apilot wishes to fly from bayfield to kitchener, a distance of 100 km on a bearing of 105°. the speed of the plane in still air is 240 km/h. a 20 km/h wind is blowing on a bearing of 210°.
remembering that she must fly on a bearing of 105° relative to the ground (ie the resultant must be on that bearing), find
a) the heading she should take to reach her destination.
b) how long will the trip take

a

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

(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.
