Find the surface area of a sphere with a radius of feet. 35.5 square feet

94.5 square feet

25.1 square feet

100.5 square feet

c.

step-by-step explanation:

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512

(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.

i believe a. 12x≥120 is the answer
