Answer:
Amplitude = 3.5
Step-by-step explanation:
The amplitude of a sinusoidal function is one-half of the positive difference between the maximum and minimum values of a function.
Given the cosine function
The maximum and the minimum values of the function are 1 and -1, so the maximum and the minimum values of the function are 3.5 and -3.5.
Positive difference:
Half of the difference:
The cost she needs to pay is $292.55
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Cost for first month= 55
Cost for other months= 47.5
Now she has to pay for six month
=$47.50(5)+$55
=$237.50+$55
=$292.55

y=$47.50(5)+$55
y=$237.50+$55
y=$292.55
y=total
m(47.50+ amount increased by after the starting $55
b=$55; the start.
