Point form would be (1,-2)
For this case we must find an expression equivalent to the following:
![5 \sqrt {13 ^ 3}](https://tex.z-dn.net/?f=5%20%5Csqrt%20%7B13%20%5E%203%7D)
By definition of properties of powers and roots we have:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
In addition, we know that:
![13 ^ 3 = 13 ^ 2 * 13](https://tex.z-dn.net/?f=13%20%5E%203%20%3D%2013%20%5E%202%20%2A%2013)
Rewriting the given expression we have:
![5 \sqrt {13 ^ 3} = 5 \sqrt {13 ^ 2 * 13} = 13 * 5 \sqrt {13} = 65 \sqrt {13}](https://tex.z-dn.net/?f=5%20%5Csqrt%20%7B13%20%5E%203%7D%20%3D%205%20%5Csqrt%20%7B13%20%5E%202%20%2A%2013%7D%20%3D%2013%20%2A%205%20%5Csqrt%20%7B13%7D%20%3D%2065%20%5Csqrt%20%7B13%7D)
Answer:
![65 \sqrt {13}](https://tex.z-dn.net/?f=65%20%5Csqrt%20%7B13%7D)
I= PRT
I= 1400 X 0.015 X 0.5
I= 21 X 0.5
I= 10.5
if it was a full 12 months it would be
21 x 1= 21
if it was 1/5 years it would be
21 x 1.5 = 31.5 and so on
Answer:
picture no 1 is not a function.
picture no 2 is a function.
