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.

I need help with this problem! I'll give brainlist! ​
aliya0001 [1]

Step-by-step explanation:

use CAH method (Cos angle = adjacent/hypotenuse)

Given adjacent = 5

Hypotenuse = 12,

\cos(x) =  \frac{adjacent}{hypotenuse}  \\  \cos(x)  =  \frac{5}{12}  \\ x =  {cos}^{ - 1} ( \frac{5}{12} ) \\  = 65.4deg(nearest \: tenth)

What is the measurement of angle 1?
Andrei [34K]

Answer:

<u>Angle 1</u>= 180 - 110 = 70 (straight angle)

<u>Angle 2</u> = 180 - 115 =65 (straight angle)

<u>Angle 3</u>= angle 2 =65 (corresponding alternating angles)

<u>Angle 4</u> =180 - angle3 = 180 - 65 = 115 (straight angle)

<u>Angle 5</u> = 180 - angle 1 - angle 3= 180 - 70 - 65 = 45 (sum of triangle angles is equal to 180)

<u>Angle </u><u>6</u> = angle 5= 45 ( interior alternating angles)

<u>Angle</u><u> </u><u>7</u><u> </u>= angle 6= 45 (vertical opposite angles)
