Guided Practice Write the equation of the parabola in vertex form. The vertex is (−4, −3) and the parabola passes through the point (−1, −48). Create a rough sketch of the graph to use as a visual aid.

A.
y = −16(x + 3)^2 + 4

B.
y = −5(x + 4)^2 − 3

C.
y = −(x − 4)^2 − 3

D.
y = −5(x − 4)^2 − 3

Describe in detail how you would construct a 95% confidence interval for a set of 30 data points whose mean is 20 and population standard deviation is 3. be sure to show that you know the formula and how to plug into it. also, clearly state the margin of error.

Choose the point slope form of the equation below that represents the like that passes through the points (-6,4) and (2, 0)

Which situation can be modeled by the inequality 5 + 10w ≥ 45? a. you start with $5 and save $10 a week until you have at least $45. b. you start with 5 baseball cards and purchase 10 cards every week until you have at most 45 cards. c. you start with 5 water bottles and purchases cases of 10 water bottles each until you have a total of 45 water bottles. d. you spend $5 plus $10 per week until you have less than $45.
