The value of n would be 4 because 5 times 4/5 is 4, which would equal n
Answer: $6000
Explanation:
1) Simple interest means that the interests are calcualted over the original amount borrowed and they are the same every year.
2) yearly interest = interest / number of years = $2400 / 10 = $240
3) the yearly interest equals the amount borrowed times the simple intereset rate:
=> $240 = A * 4%
=> $240 = A * 0.04
=> A = $240 / 0.04 = $6000
You can do the same in one step:
interest = A * simple interest rate * number of years
=> A = interest / [simple interest rate * number of years] = $2400 / [4% * 10]
A = $2400 / (0.04 * 10) = $2400 / 0.4 = $ 6000.
And that is the answer: he borrowed $6000

Answer:
x = ln (33)
------------
3 ln (2)
Step-by-step explanation:
2 ^ (3x) = 33
Take the ln of each side
ln ( 2 ^ (3x)) = ln 33
We know ln ( a^b) = b ln a
3x ln (2) = ln 33
3x = ln 33
------------
ln 2
Divide each side by 3
x = ln (33)
------------
3 ln (2)

Answer:
x ≈ 32.4
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between angle, adjacent side, and hypotenuse:
Cos = Adjacent/Hypotenuse
cos(72°) = 10/x
x = 10/cos(72°)
x ≈ 32.4
