Equation for parabola is
y = a ( x - h ) ^2 + k where (h,k) is the vertex of the parabola.
Given: vertex (-4, -1) h = -4; k = -1
y = a (x - (-4))^2 + (-1)
y = a ( x + 4)^2 - 1 plug in the values given for x and y. y-value is 0 and x-value is 2
0 = a (2 + 4)^2 -1
0 = a (6)^2 -1 square 6
0 = a 36 - 1 add 1 to both sides to isolate the a
1 = 36 a divide both sides by 36 to isolate the a
1/36 = a the coefficient.
i think you might have typed a number incorrectly if those are your answer choices. Maybe the step by step process can still help you with your correct numbers. :-)
45 yard = 1215 cubic feet
Based on that, i think the answer is : C. The Volume of the prisms stays the same, but the number representing the volume increases
Yard and feet are only unit of measurement. Changing this does not affect the actual volume
hope this helps

Answer:
y = -2/3x + 8
Step-by-step explanation:
Format: y = mx + b
m = slope (rise over run) - 2/3 The graph is negative so the slope is also negative.
b = y - intercept (8)
Answer:
44 marbles.
Step-by-step explanation:
Each received 6 marbles so that is a total of 6*7 = 42 marbles.
As there were 2 left over the total = 42 + 2 = 44 marbles.
