if you deposit $8000 into an account paying 9% annual interest compunded semi anually how long will it take for your money to do

Anna007 [38]

Answer:

7.87 years

Step-by-step explanation:

#First we determine the effective annual rate based on the 9% compounded semi annual;

$i_m=(1+i/m)^m-1\\\\=(1+0.09/2)^2-1\\\\=0.09203$

#We then use this effective rate in the compound interest formula to solve for n. Given that the principal doubles after 2 yrs:

$A=P(1+i)^n\\\\A=2P, i=i_m\\\\16000=8000(1.09203)^n\\\\2=1.09203^n\\\\n=\frac{log \ 2}{log \ 1.09203}\\\\=7.87324\approx7.87 \ yrs$

Hence, it takes 7.87 years for the principal amount to double.

20 points!!! first answer gets brainliast. Don't need too much explanation thank you!

Answer:

The answer to your question is below

Step-by-step explanation:

2. $\sqrt{-128}$ Just find the prime factors of 128 and simplify

$\sqrt{-2^{7}} = \sqrt{-2^{6} 2} = 2^{3}i \sqrt{2}$

$8i\sqrt{2}$

3.- $\sqrt{-9} + \sqrt{-16}$ Get the square roots and simplify

3i + 4i

4.- None of the choices is equal to one, because the exponents are pair.

5.- 1/3x² + 10 = 7

1/3x² = 7 - 10

1/3x² = -3

x² = -3(3)

x² = -9

x = ±3i

REY [17]

Answer:

Y= 1 (x^2-2)-5

Step-by-step explanation:

Use vertex form: y= a(x-h)+<u>k: k is what shifts the parbola up or down. Positive shifts it up while negative shifts it down.</u>
