When Gavin left his house in the morning, his cell phone battery was partially charged. The charge remaining in Gavin's battery, as a percentage, can be modeled by the equation B=28-7t, B=28−7t, where tt is the number of hours since Gavin left his house. What is the yy-intercept of the equation and what is its interpretation in the context of the problem?

6 meters

step-by-step explanation:

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

i think the answer would be c

(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.
