Please provide a step-by-step instruction: You deposit $6,900 in a 2-year certificate of deposit (CD) earning 2.2% annual intere

st compounded daily. At the end of the 2 years, you reinvest the compound amount plus an additional $6,900 in another 2-year CD. The annual interest rate on the second CD is 2.7%, compounded daily. What is the compound amount (in dollars) when the second CD matures? (Enter a number. Round to the nearest cent. Assume all years have 365 days.)

Answer: the compound amount when the second CD matures is $14889.9

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = 6900

r = 2.2% = 2.2/100 = 0.022

n = 1 because it was compounded once in a year.

t = 2 years

Therefore,.

A = 6900(1 + 0.022/1)^1 × 2

A = 6900(1.022)^2

A = 7206.9396

The amount reinvested in the second account is

7206.9396 + 6900 = $14106.9396

r = 2.7% = 0.027

t = 2 years

n = 365 because it was compounded daily . Therefore,

A = 14106.9396(1 + 0.027/365)^2 × 365

A = 14106.9396(1.000074)^730

A = 14106.9396 × 1.0555

A= $14889.9

How many seconds equal 3.6 hours?

MAXImum [283]

12960 seconds equals 3.6 hours.

since its 3.6 hours we need to calculate it so one minute = 60 seconds and 60 minutes = a hour so those are the basics to solve this. now u have add 1 minute of 60 minutes to equal just one hour which gets u 3 if u do it 3 times.

Find the equation of the line that passes through point (6, 1) with the x-intercept of 2.

34kurt

<u>Answer:</u>

○ $y = \frac{1}{4}x - \frac{1}{2}$

<u>Step-by-step explanation:</u>

To find the equation of the line, let's first consider the points whose coordinates we have been given:

• (6, 1)

• (2, 0).

The point (2, 0) is what is called the x-intercept, which is the point where the line crosses the x-axis. This means that at this point, the y-coordinate of the line is 0.

Next, let's calculate the slope (gradient) of the line using the formula:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

where:

m = gradient,

$(x_2, y_2)$ and $(x_1, x_2)$ = points on the line.

Using the formula:

$m = \frac{1 - 0}{6 - 2}$

⇒ $m =\bf \frac{1}{4}$

Finally, now that we have two points on the line as well as the line's slope, we can use the following formula to find the equation of the line:

$\boxed{y - y_1 = m(x - x_1)}$

You can use any of the points on the line as $y_1$ and $x_1$ .

Using (2, 0):

$y - 0 = \frac{1}{4}( x - 2)$

⇒ $y = \frac{1}{4}x - \frac{1}{2}$

Therefore the equation of the line is $y = \frac{1}{4}x - \frac{1}{2}$ .
