Using the given values from the problem and the illustration, three points are known which are (0,0), (6.5,-31), (-6.5,-31). The first step in solving this problem is to determine the equation of the parabola.
y = ax²
-31 = a(6.5)²
-31 = 42.25a
a = -31/42.25
a = -124/169
Therefore, the equation of the parabola is y = (-124/169)x². The value 4.5 is then substituted in the equation as x to get the answer which is 16.14 meters.
Answer:
C
Step-by-step explanation:
Factor: -7x^2 -5x+18
Factor -1 out of 7x^2 -5x +18:
−(7x^2+5x−18)
Factor.
1. 18 is negative, so a negative number multiplied by a postive number.
2. You can't factor 7, so 7x times x.
(7x−9)(x+2)
The answer is D
Because, if there is 50 calories in 4 ounce serving of juice, then you do how many times 4 equals 12. 3 times 4 equals 12. so you will use 3 to multiply by 50 and you get 150 calories in 12 ounces.

Answer:
2 /10
Step-by-step explanation:
The portion of the book that weight 2 1/8
Total number of books = 10
Number of books that weight 2 1/8 = 2
Fraction of book that weigh 2 1/8 = number of books that weigh 2 1/8 / total number of books
Fraction = 2 / 10
