Find the value of x if 7,x and 11 are in A.p.​
krok68 [10]

Answer:

x = 9

Step-by-step explanation:

since the terms are in AP then there is a common difference between consecutive terms, that is

a₂ - a₁ = a₃ - a₂ ( substitute values )

x - 7 = 11 - x ( add x to both sides )

2x - 7 = 11 ( add 7 to both sides )

2x = 18 ( divide both sides by 2 )

x = 9

Suppose you invested $1500 in an ac count that paid an annual of 3% compound monthly. How much would you have after 1 year?
Sati [7]

Answer:

1545.62

Step-by-step explanation:

The calculation of compound interests uses this formula:

<h2>A = P (1 + \frac{r}{n} )^{n*t}</h2>

Where  A = total amount, P = principal or amount of money deposited, r = annual interest rate, n = number of times compounded per year  and t = time in years.

So, if we plug-in the numbers of the problem we have:

<h2>A = 1500 (1 + \frac{0.03}{12} )^{12*1}</h2>

Which gives us:

A = 1500 * 1.0025^{12} = 1500 * 1.030416 = 1545.62

For a grand total of 1,545.62 including capital and interests.
