Answer:
Step-by-step explanation:
The coefficients of the x terms are {1, 3, -3}, so the discriminant, b^2 - 4ac, is 3^2 - 4(1)(-3), or 9 + 12, or 21. The positive nature of the discriminant tells us that there are two real, unequal roots. Following the quadratic formula, we get:
-3 ± √21
x = -----------------
2

Step-by-step explanation:
Lucy studies one less (-1) than twice the number of hours a week that rose studies (2 * R), lucy studies 11 hours a week. What we do is add 1 hour to lucy's 11, to get 12, then divide by 2 as lucy studies twice the hours. 12 / 2 = 6.
Answer: 123,060
So you multiply 1700 by 12 then add 110 then divide by 12 to see how much you would now pay a year, which would be 1709 (new monthly payment) then multiply that by six years 12 month's time 6 years = 72 months so multiply 1700 times 72 and you get 123060

Answer:
The horizontal distance traveled by the ball before it hits the ground is 550 ft
The graph in the attached figure
Step-by-step explanation:
we have
Using a graphing tool
we know that
The horizontal distance traveled by the ball before it hits the ground is equal to the horizontal distance from the origin to the x-intercept of the graph
so
The horizontal distance is 550 ft
see the attached figure
