A) it represents trough fill rate. It basically states after 8 minutes, the water level raised 28 cm.
B) for every 1 minute of pouring, the water level rises 3.5 centimeters.
C) if you look at those points as proportions
6/21 = 1/3.5
Or 8/28 = 1/3.5
They both can be proportionate.
ANSWER- (1,-2)
VERTEX is the highest point of the parabola (the U shaped graph)
Cross multiply (multiply 18 on both sides to get rid of the 18 in the denominator, and multiply "x" on both sides to get rid of the x in the denominator
36 = x² Square root both sides to get rid of the ², and to get "x" by itself
√36 = √x²
±6 = x Your answer is 6
You could have just done this too:
2(18) = x(x)
36 = x²
√36 = √x²
±6 = x
