A scientist changes the temperature of a solution at a rate of -8°C per minute. How many minutes will it take for the
solution's temperature to change from 0°C to -88°C?

11 minutes

Step-by-step explanation:

I may be missing something. This is too simple.

88 degree change at 8 degrees per minute = 11 minutes.

(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.
