$800 is deposited in an account

Sergeeva-Olga [200]

Answer:

The balance after four years is $1129.27

Step-by-step explanation:

The formula for compound interest, including principal sum, is $A=P(1+\frac{r}{n})^{nt}$

A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = the time the money is invested or borrowed for

∵ $800 is deposited in an account

∴ P = 800

∵ The account pays 9% annual interest

∴ r = 9% = 9 ÷ 100 = 0.09

∵ The interest is compounded annually

∴ n = 1

∵ The time is 4 years

∴ t = 4

- Substitute the values of P, r, n, and t in the formula above

∵ $A=800(1+\frac{0.09}{1})^{(1)(4)}$

∴ $A=800(1.09)^{4}$

∴ A = 1129.265

∴ The balance after four years is $1129.27

Kate has a kite with the dimensions shown below. What is the value of X?

sergij07 [2.7K]

Hey there! :D

We will use the properties of similar triangles to figure this out.

We will use two triangles inside the kite, with sides with the value of "x".

Smaller triangle:

Smaller side= 11

Bottom side= x

Bigger triangle:

Smaller side= x

Bottom side= 25

$\frac{11}{x} = \frac{x}{25}$

Cross multiply.

25*11= 275

x*x= $x^{2}$

Find the square root.

√275= 16.583....

Or 5√11.

I hope this helps!
