Answer: 23
Step-by-step explanation:
1. Divide the amount Lynn paid for the ribbon, 17.25, by the amount the ribbon cost per foot, 0.75, to get how many feet of ribbon she bought.
17.25 / 0.75 = 23
<span>1800 = -3p^2+70p+988
0 = -3p^2+70p - 812
Using the discriminant means taking the section of the quadratic formula:
âšâ€‹(b^2)â’4ac
And by plugging in the values of our formula we get:
âšâ€‹(70^2)â’4*-3*-812
Which yields:
âšâ€‹4900 â’ 9744
Since this is a square root of a negative number, it says there is no real solution for the formula, which makes sense because the formula is a quadratic that is pointing downwards (a = -3p^2) and underneath the number line (c = -812).
