-296.2i would be an imaginary number.
Answer:
Step-by-step explanation: If interest is compounded yearly, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12; weekly, then n = 52; daily, then n = 365; and so forth, regardless of the number of years involved. Also, "t" must be expressed in years, because interest rates are expressed that way.

Answer:
The repulsive force is
.
Step-by-step explanation:
Consider the provided information.
The coulomb's law to calculate the repulsive force: 
Where the value of k is 9.00×10⁹ Nm²/C²
Substitute the respective values in the above formula.
![F=\frac{9\times10^9\frac{N\cdot m^2}{c^2} \times(-24\times10^{-9}C)^2}{[(13 cm)(\frac{1m}{100cm} )]^2}](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B9%5Ctimes10%5E9%5Cfrac%7BN%5Ccdot%20m%5E2%7D%7Bc%5E2%7D%20%5Ctimes%28-24%5Ctimes10%5E%7B-9%7DC%29%5E2%7D%7B%5B%2813%20cm%29%28%5Cfrac%7B1m%7D%7B100cm%7D%20%29%5D%5E2%7D)



Hence, the repulsive force is
.
Answer:
1/4 b^9
Step-by-step explanation:
(b^11 b^-7)/4b^-5
We know x^y * x^z = x^(y+z)
b^11 * b^ -7 = b^ (11-7) = b^4
(b^11 b^-7)/4b^-5
b^4 / 4 b^-5
We know x^y / x^z = x^(y-z(
b^4 / b^-5 = b^(4 - -5) = b^(4+5) = b^9
1/4 b^9
