Answer:
p <= 19
Step-by-step explanation:
We have that the area of a sheet of paper is:
8.5 ft * 11 ft = 93.5 ft ^ 2
So the area of the bulletin board would come from:
1728 / 93.5 = 18.48 pieces of paper.
What it means is that the solution is a number greater than 18.48, an inequality this case represents would be:
p <= 19
Which means, as long as it's under 19, I could hang it up. It is approaching 19 because this type of situation approaches the largest number.
It is the first graph on e2020 :)
The equation for the sin function is: Asin(BX-C),
A is the amplitude.
The period is: 2pi/B
The phase shift is: C/B
So, if we know the amplitude A, the period and the shift, we can calculate B from the period: B=2pi/period and we can in the next step calculate C= B*phase shift.
