In the value of bonds, the symbol "M" means "thousands.
Therefore, 10 M = 10,000$
So, the customer bought a coupon with 10,000$ and the expected annual interest is 7.5% of the coupon's value.
Calculating the value of interest is simple, just multiply the interest rate (7.5%) by the original value of the coupon to know how much interest she will collect each year.
Interest collected each year = (7.5 / 100) x 1000 = 750$

Move everything to the left by subtracting 25 from both sides:

Both terms are squares:
is the square of
, while 25 is the square of 5. So, we can apply the factoring

To factor the expression as

A multiplication is zero if and only if one of the factors is zero, so we have

2
The discriminant of the quadratic expression
is defined as

So, you have

3
Similarly, we have

Answer:
Step-by-step explanation:
the domain for (2x-1)/(x^2-7) is x not equal to +/- sqrt(7)
Answer:

Step-by-step explanation:
Given the following question:

In order to convert a mixed number into an improper fraction we have to divide the numerator (in this case; 22) by the denominator (in this case; 6) to find your answer.




Let three represent how many times 3 goes into 11, let 2 represent the remainder while of course keeping the denominator the same. Your answer is "3 2/3."
Hope this helps.
