The perimeter of a rectangular playing field is 140 feet. The length of the field is 10 feet more than the width. What are the dimensions of the playing field? (You need to find the
length and the width.)

w=14 h=10

Step-by-step explanation:

is the length 10 and the width is 14 right bc if you multiply 10 by 14 you get 140.

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.
