find real numbers a, b, and c so that the graph of the function y=ax^2+c contains the points (-1,6), (2,7), and (0,1)
1 answer:
This gives you three simultaneous equations: 6 = a + c 7 = 4a + c 1 = c <u>c = 1 </u> <u /> <u /> If c =1, 6 = a + 1<u>a = 5 </u> <u /> <u /> This doesn't work in the second equation, so the quadratic that goes through these points is not in the form y = ax^2 + bx + c Was there supposed to be a b in the equation?

Answer:
139.888 $
Step-by-step explanation:
Data :
15 ft = 24.98$
So
1 yard = 3 ft
15ft / 3 ft = 5 yard
So
5 yard = 24.98$
28 yd / 5yd = 5.6
5.6 × 24.98 = 139.888
