Collete mapped her vegetable garden on the graph below. Each unit represents 1 foot.
1 answer:
Answer:
<h2>(-4,-1) and (-4,7)</h2>Step-by-step explanation:
If Collete planted a row of lettuce, that means their coordinates must have the same vertical coordinate, or the same horizontal coordinate. Another important characteristic is that between those points, there must have 8 units of separation, because it's an 8-foot row.
Only the first choice offers these characteristic to properly represent the row of plants with 8 feet distance between the first and the last plant.
Therefore, the answer is (-4,-1) and (-4,7)

<u>Answer:</u>
<u>Step-by-step explanation:</u>
The function is defined as:
To calculate the value of , we have to replace the
in the definition of
with -2:
=
⇒
⇒ -96 - 15
⇒ -111
Start by setting the function equal to 0 and then moving the -5.4 over to the other side of the equals sign. 
. The first rule for completing the square is that the leading coefficient be a +1. Ours is a -.2. So we need to factor it out. 
. Now we will take half the linear term, square it, and add it to both sides. Our linear term is 14. Half of 14 is 7, and 7 squared is 49. So we add 49 in to the left side just fine, but we cannot forget about that -.2 hanging around out front as a multiplier. What we have actually "added" in is -.2*49 which is -9.8. Now here's what we have after all that: 
. In that process, we have created a perfect square binomial on the left. Along with expressing that binomial we will do the math on the right: 
. Now we will move the -4.4 back over by addition, and it will then be apparent as to what our vertex is. The y coordinate of the vertex will give us the max height of the water. 
. As you can see, our work matches choice C from above.
