Question

The function E (t) models the daily electrical output, in kilowatthours, from the solar panels on Agnes's home on the tᵗʰ day of the year E(t)-11.5 sin (2π/365(t-18))+25 What does the solution set for y = 11.5 sin (π/2)+25 represent? Choose 1 answer: A) The minimum daily electrical output of the solar panels B) The set of all days of the year on which the solar panels output their minimum. C) number of kilowatthours The maximum daily electrical output of the solar panels

Answer 1

The solution set y = 11.5 sin (π/2) + 25 represents the days when the daily electrical output from the solar panels is zero.

Step-by-step explanation:

The function E(t) models the daily electrical output from the solar panels on Agnes's home on the tᵗʰ day of the year. The expression E(t) = -11.5 sin(2π/365(t-18)) + 25 represents the daily electrical output in kilowatthours. To find the solution set for y = 11.5 sin (π/2) + 25, we substitute 11.5 sin (π/2) + 25 into the expression for E(t).

This simplifies to E(t) = 0. This means that the solution set y = 11.5 sin (π/2) + 25 represents the days when the daily electrical output from the solar panels is zero.
