Answer:
The club must sell 18 jackets to break even
Step-by-step explanation:
Given:
C = 20x + 270
Where,
x = number of jackets
Equation for revenue R in terms of the number of jackets
Revenue = price × quantity
Price of the jacket = $35
Quantity of the jacket = x
Revenue = price × quantity
= 35 * x
R = 35x
Break even point is the point at which cost is equal to revenue, that is, no gain; no loss.
Cost = revenue
20x + 270 = 35x
270 = 35x - 20x
270 = 15x
x = 270 / 15
= 18
x = 18 jackets
The club must sell 18 jackets to break even
2 and 12 both correspond with angle 5

The given sinusoidal function is
This function is of the form:
where
a=|-3.5|=3.5 is the amplitude.
Therefore the amplitude of the given sinusoidal function is 3.5
Answer:
369
Step-by-step explanation:
P(t)=number of sheet of paper after t minutes.
p(t) will have to be equal to 0, wnen the printer use all 100 sheets of paper;
Therefore;
if p(t)=0
Then:
-8t+100=0
We solve this equation.
-8t+100=0
8t=100
t=100/8
t=12.5
Answer: the printer prints 100 sheets of paper in 12.5 minutes.
