Complete Question:
Which statement about the following equation is true?
A) The discriminant is less than 0, so there are two real roots
B) The discriminant is less than 0, so there are two complex roots
C) The discriminant is greater than 0, so there are two real roots
D) The discriminant is greater than 0, so there are two complex roots
Answer:
C) The discriminant is greater than 0, so there are two real roots
Step-by-step explanation:
The given equation is which by simplification becomes
For a quadratic equation of the form , the discriminant is given by the equation,
If the discriminant D is greater than 0, the roots are real and different
If the discriminant D is equal to 0, the roots are real and equal
If the discriminant D is less than 0, the roots are imaginary
For the quadratic equation under consideration, a = 2, b = -9, c = 3
Let us calculate the discriminant D
D = (-9)² - 4(2)(3)
D = 81 - 24
D = 57
Since the Discriminant D is greater than 0, the roots are real and different.
The percentage of the payments made were due to interest is 32.6 %. Then the correct option is B.
<h3>What is the percentage?</h3>The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
The following table shows a portion of a five-year amortization schedule.
A 5-year amortization schedule.
Loan amount or principal: 10,900 dollars.
The interest rate on loan: 10. 95 percent.
The table will be
Month Payment Principal Interest Balance
15 236.72 155.87 80.85 8704.27
16 236.72 157.29 79.43 8546.98
17 236.72 158.73 77.99 8388.25
18 236.72 160.18 76.54 8228.07
19 236.72 161.64 75.08 80.66.43
20 236.72 163.11 73.61 7903.32
Total payment = 6 × 236.72 = $ 1420.32
Total interest = 80.85 + 79.43 + 77.99 + 76.56 + 75.08 + 73.61
Total interest = $ 463.38
Then the percentage will be
