Answer:
<u>If the amount is P, with the interest rate of 12%, the interest over the year is:</u>
<u>In this case the quarterly interest rate is:</u>
<u>With the same amount and 3% quarterly rate, the yearly interest would be:</u>
<u>The quarterly interest rate in this case is:</u>
If the quarterly interest rate is r, it should be little less than 3% to yield a 12% yearly rate.
So Kraig is wrong.
Answer:
If Discriminant,
Then it has Two Real Solutions.
Step-by-step explanation:
To Find:
If discriminant (b^2 -4ac>0) how many real solutions
Solution:
Consider a Quadratic Equation in General Form as

then,
is called as Discriminant.
So,
If Discriminant,
Then it has Two Real Solutions.
If Discriminant,
Then it has Two Imaginary Solutions.
If Discriminant,
Then it has Two Equal and Real Solutions.
