FromTheMoon [43]

Answer:

No, because 1.25% times 3 is 3.75% which is less than 6%

Step-by-step explanation:

Quarterly is every 3 months

6% interest is 1.06, 6 cents on the dollar

Monthly interest rate is 1.25% so 1.25 × 3 is 3.75

So, 1.25% times 3 is 3.75% which is 2.25% less than 6%

Hope this helps!

Have a great day!

f(x)=−7x 2 +8x+2f, left parenthesis, x, right parenthesis, equals, minus, 7, x, squared, plus, 8, x, plus, 2 What is the value o
vlada-n [284]

The discriminant of the function is 120, and the function has 2 different x-intercepts

<h3>How to determine the discriminant?</h3>

The function is given as:

f(x) = -7x^2 + 8x + 2

The discriminant (d) is calculated using:

D =b^2 - 4ac

So, we have:

D = 8^2 - 4 * (-7) * 2

Evaluate

D = 120

Because the value of D is greater than 0, then the function has 2 different x-intercepts
