Answer:
Step-by-step explanation:
take 45 degree as reference angle
using sin rule
sin 45 =opposite /hypotenuse
1/
=24/k(do cross multiplication)
24
=k
Answer:
maybe number 2
Step-by-step explanation:
because if 2+k=18 then there is no other k there and where did the additional 2 come from ?and 2k=18 then value of k is 9 + there is balance.I may be wrong correct me but i think it is no.2
$7881.18
Step-by-step explanation:
Let the initial Investment be
. The Interest is compounded on a monthly basis at 12% annual interest rate. After 17 years, the Investment amounts to $60,000.
As the annual interest rate is 12%, the monthly interest rate is 1%.
Since this is a compound interest problem, the total amount can be modeled as follows: ![P(t)=P_{0}(1+\frac{i}{100})^{t}](https://tex.z-dn.net/?f=P%28t%29%3DP_%7B0%7D%281%2B%5Cfrac%7Bi%7D%7B100%7D%29%5E%7Bt%7D)
Here
is the interest rate, i.e
, and t is the number of time periods, i.e
= ![204\textrm{ months}](https://tex.z-dn.net/?f=204%5Ctextrm%7B%20months%7D)
![60,000=P_{0}\textrm{ x }(\frac{101}{100})^{204}](https://tex.z-dn.net/?f=60%2C000%3DP_%7B0%7D%5Ctextrm%7B%20x%20%7D%28%5Cfrac%7B101%7D%7B100%7D%29%5E%7B204%7D)
![P_{0}=7881.18](https://tex.z-dn.net/?f=P_%7B0%7D%3D7881.18)
∴ Initial Investment = $7881.18
