Answer: 13 is c im pretty sure and 14 is a im think hope fully it helps
Step-by-step explanation:
Answer:
Therefore the period of the sinusoidal wave = 3.14.
The amplitude of the function = 2.
Step-by-step explanation:
The period of a sinusiodal wave is given by the length of x axis which covers one full cycle of the wave, which one positive half-cycle and one negative half cycle.
From the graph we can see that one of the cycles starts at -3.14 / 4 and ends at 3.14 3/4.
Therefore we can sutract the start point value from the end point value to get the period
Therefore period = (3.14 3/4) - (-3.14 / 4) = (3.14 3/4) + (3.14 / 4) = 3.14
Therefore the period of the sinusoidal wave = 3.14.
The amplitude of the function = 2.
We are asked to solve for the interest during the year given that it is compounded monthly, we are given with the formula A = P(1+r)^n. The solution is shown below:
A = P (1+r)^n
A = $5,000 (1+ 3.5/12)^(12*1)
A = $5,000 (1.000292)^12
A = $5,177.84
