a light bulb consumes 6300 watt hours in 3 days and 12 hours. how many watt hours does it consume per day

1800 watt hours

Step-by-step explanation:

6300 watt hours in 3 days and 12 hours

3 x 24 = 72 3 days worthof hours

72 + 12 = 84 total hours

6300/84 = 75 watt hours per hour

75 x 24 = 1800 watt hours per day

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.
