Answer:
$323
Step-by-step explanation:
The monthly payment can be calculated using the formula:
![M=\frac{P(\frac{r}{12})(1+\frac{r}{12})^n}{(1+\frac{1}{12})^n-1}\\\\](https://tex.z-dn.net/?f=M%3D%5Cfrac%7BP%28%5Cfrac%7Br%7D%7B12%7D%29%281%2B%5Cfrac%7Br%7D%7B12%7D%29%5En%7D%7B%281%2B%5Cfrac%7B1%7D%7B12%7D%29%5En-1%7D%5C%5C%5C%5C)
where:
- M=monthly payment
- P=amount borrowed
- r=annual interest rate
- n=total number of monthly payments:
Our parameters are defined as:
![n=60\\P=21000-4000=17000\\r=5.3%\\\\](https://tex.z-dn.net/?f=n%3D60%5C%5CP%3D21000-4000%3D17000%5C%5Cr%3D5.3%25%5C%5C%5C%5C)
We plug our parameters in the equation to solve for M;
![M=M=\frac{P(\frac{0.053}{12})(1+\frac{0.053}{12})^n}{(1+\frac{0.053}{12})^{60}-1}\\\\\\\\](https://tex.z-dn.net/?f=M%3DM%3D%5Cfrac%7BP%28%5Cfrac%7B0.053%7D%7B12%7D%29%281%2B%5Cfrac%7B0.053%7D%7B12%7D%29%5En%7D%7B%281%2B%5Cfrac%7B0.053%7D%7B12%7D%29%5E%7B60%7D-1%7D%5C%5C%5C%5C%5C%5C%5C%5C)
![=\frac{P(\frac{0.053}{12})(1+\frac{0.053}{12})^{60}}{(1+\frac{0.053}{12})^{60}-1}\\\\\\=323.15](https://tex.z-dn.net/?f=%3D%5Cfrac%7BP%28%5Cfrac%7B0.053%7D%7B12%7D%29%281%2B%5Cfrac%7B0.053%7D%7B12%7D%29%5E%7B60%7D%7D%7B%281%2B%5Cfrac%7B0.053%7D%7B12%7D%29%5E%7B60%7D-1%7D%5C%5C%5C%5C%5C%5C%3D323.15)
![=323.15\approx\$323](https://tex.z-dn.net/?f=%3D323.15%5Capprox%5C%24323)
Hence, the monthly payment is $323
Sin 45 = 62.5/h
h = 62.5 / sin 45
h = 88.3 cm
Answer:
Step-by-step explanation:
the first one is 9 and the third one is -3 so you minus 9 and you get zero but then you have to get -3 so you minus another 3 and then you get 12 the different is 12
