Answer:
Step-by-step explanation:
In a quadratic equation in the Standard form
You need to remember that "a", "b" and "c" are the numerical coefficients (Where "a" is the leading coefficient and it cannot be zero: 
).
You can observe that the given quadratic equation is written in the Standard form mentioned before. This is:
Therefore, you can identify that the values of "a", "b" and "c" are the following:
Answer:
10.25
Step-by-step explanation:
Using the pythagorean theorem
13^2 = 8^2 + (ML)^2
169 = 64 + (ML)^2
Subtract 64 from both sides
105 = (ML)^2
Take the square root of both sides
10.25 = ML

Answer:
5
Step-by-step explanation:
Distance from B to B' is equal to the distance from A to A', AA'=5 so BB'=5
We use the ratio x:360 to find portions of the circle (again, through the ratio)
so we use 60/360 = x/30 in^2
1/6 = x/ 30
x = 5.
The answer is 5 in^2
