The perimeter of a rectangular pool is 312 m. If the width of the pool is 68 m, what is its length?
Length of the pool:
m

The perimeter of a rectangle is calculated by:

Remember: In a rectangle, opposite sides are equals.

If we know how much is the width, then it's just apply it to the expression:

Therefore, the length of the pool is 88m.

(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.

p - 6

step-by-step explanation

so you know that it cost $6 to see a movie you subtract p - 6 to get your answer

hope this !
