Answer:
The vertex (h,k) is (-4,-7).
Step-by-step explanation:
I assume you are looking for the vertex 
.
The vertex form of a quadratic is 
where the vertex is (h,k) and a tells us if the parabola is open down (if a<0) or up (if a>0). a also tells us if it is stretched or compressed.
Anyways if you compare to , you should see that 
.
So the vertex (h,k) is (-4,-7).

Answer:
Mai has less variability as compared to that of Priya
Step-by-step explanation:
IQR is the Inter quartile range and is the difference between upper and lower quartiles. It measures the variability as in terms it depicts the middle 50% of values when the values are arranged in ascending order
In case of Priya's median score was 118, and her IQR was 15. IQR = 15 means that there is a difference of 15 between the upper and lower quartiles
While in case of Mai, the IQR is 5 only.
Hence, Mai has less variability as compared to that of Priya

Answer:
81 cubic feet of wood
Step-by-step explanation:
Divide it into 5 sections, each 3 feet long because it is 15 feet long.
(1*3*3) + (2*3*3) + (3*3*3) + (2*3*3) + (1*3*3) =
9 + 18 + 27 + 18 + 9 = 81
