Answer:
15 percent
Step-by-step explanation:
- 30/200=15/100
- 15/100=0.15
- 0.15=15 percent
(x^m) times (x^n)=x^(m+n)
(1/8)^5 times (1/8)^3=(1/8)^(5+3)=(1/8)^8=1/(8^8)
Answer:

Step-by-step explanation:
We are given the following;
- Vertex of a quadratic function = (5,3)
- A point where the function passes through (-1, -9)
Required to determine the equation of the function;
- We need to know the vertex form of a quadratic function is;
, where h and k correspond to the vertex (h,k)
- Therefore, we can replace the variables h and k of the vertex in the equation;
That is;

Then we use the equation and the point given to solve for a
x = -1 and y = -9
We get;

Substituting the values of a, h and k in the equation, we get;

Thus, the equation of the function in the vertex form is 
Answer: 12.50$
Explanation: 5.25$ (per pound) and he wants 3 pounds so we multiply 5.25x3 which equals 15.75 and then we subtract 3.25 (because of the coupon) which makes your final answer 12.50$
