A person invests 3000 dollars in a bank. The bank pays 6.75% interest compounded
stich3 [128]

Answer:

12.1 years

Step-by-step explanation:

We are given that

Principal amount, P=$3000

Rate of interest, r=6.75%  semi-annually

Amount, A=$6700

We know that

When r pays semi-annually

A=P(1+\frac{r}{n\times 100})^{nt}

Where n=2

Using the formula

6700=3000(1+\frac{6.75}{200})^{2t}

\frac{6700}{3000}=(1..03375)^{2t}

2.233=(1.03375)^{2t}

Taking ln on both sides we get

ln(2.233)=2t ln(1.03375)

2t=\frac{ln(2.233)}{ln(1.03375)}

t=\frac{1}{2}\times \frac{ln(2.233)}{ln(1.03375)}

t=12.1 years

JulijaS [17]

Answer:

The amplitude is 4

Step-by-step explanation:

Recall that the amplitude of a harmonic form like this one based on the cosine function is the absolute value of the coefficient that multiplies the function. In our case that coefficient is 4.

So the amplitude of this function is "4".
