Looking at the equation, you could see that it is in vertex form. Vertex form looks like this: y=a(x-h)^2+k where a is the slope to find the first point away from the origin and (h,k) is the vertex. So, the vertex is (3,-1). The first point away from the origin is up two, over one, so the slope is 2. This means that a is 2. One way you could check this is by putting 2 in for a. If you put it into standard form, it would be 2x^2-12x+17. To find the x in the vertex when the equation is in standard form we use -b/2a. So it would give us 3 for x. If we put in 3 for x, we get -1 for y, so the vertex is (3,-1). This means that a is 2. Sorry for this lengthy answer, hope it helps.

Airlines have increasingly outsourced the maintenance of their planes to other companies. A concern voiced by critics is that th

irinina [24]

According to the information that is found in a different source, the recent data does not support the concerns of the critics. These are the numbers shown in the data:

Airline / Outsource Percent / Delay Percent

Alaska / 51.0 / 10.35

American / 29.4 / 20.32

Delta / 36.7 / 14.48

Frontier / 46.3 / 21.42

Hawaiian / 78.4 / 5.06

Based on this data, we can see that the critics do not seem to be justified in their concerns. We can see that airlines have outsourced much of the maintenance of their planes, but that there does not seem to be a strong correlation between this outsourcing and the percentage of delays. For example, the airline that outsources the most is Hawaiian (78.4%), yet it has the lowest percentage of delayed flights (5.06%).

Step-by-step explanation:

she crochets at a rate of 1/15 per day but if she can manage to get 3/15 done within maybe a day or two, then she will get 1 blanket done in 5 to 10 days. then 3 blankets could take anywhere from 15 - 30 days which leaves 30 days to spare. this probs isn’t what ur looking for but i have a pointttt
