Answer:

Step-by-step explanation:
Vertex form is

We know that h and k are both -4. Let x be -2 and y be -16.





So the equation in vertex form is

Answer:
μ = 0.169
ME = 0.051
Step-by-step explanation:
The confidence interval is:
CI = μ ± ME
So the mean is the middle of the confidence interval, and the margin of error is half the difference.
μ = (0.118 + 0.220) / 2 = 0.169
ME = (0.220 − 0.118) / 2 = 0.051
The area of a triangle is

(4.5feet)(5.75feet) and that would equal 12.9375 feet²
