Write a discussion post that contains the following:
Information about the magnetic field from the three websites you used.
What each author believes about the magnetic field.
What you believe about the magnetic field.
Citations for your three websites.
Answer:
f(x)=a(x - h)2 + k
Much like a linear function, k works like b in the slope-intercept formula. Like where add or subtract b would determine where the line crosses, in the linear, k determines the vertex of the parabola. If you're going to go up 2, then you need to add 2.
The h determines the movement horizontally. what you put in h determines if it moves left or right. To adjust this, you need to find the number to make the parentheses equal 0 when x equals -2 (because moving the vertex point to the left means subtraction/negatives):
x - h = 0
-2 - h = 0
-h = 2
h = -2
So the function ends up looking like:
f(x)=a(x - (-2))2 + 2
Subtracting a negative cancels the signs out to make a positive:
f(x)=a(x + 2)2 + 2Explanation:
A student is studying the ways that different elements are similar to one another. Diagrams of atoms from four different elements are shown above. Which two atoms are of elements in the same group of the periodic table?
Answer:
Atom 1 and Atom 4
Explanation:
On each group, the number of atoms on the outer shell is always the same as the number of the group. In atom 1 and Atom 4 there is 4 electrons on the outer shell, meaning that they are both in group 4.

i know that when wind blows aginst a sail and propels the boat but if you had a whole bunch of leaf blowers blowing at the sail would it move?
Answer:
Yes
Explanation:
Since the sail boat uses wind to move, and since you have a whole bunch of leaf blowers which are producing wind, then yes it will move.
Plants give off oxygen as part of photosynthesis. Explain the impact of this process on humans.
Answer:
Humans breathe in the oxygen that the plants produce, in return we breathe out carbon dioxide which is what plants breathe in so in total, we both are helping each other.
The process of photosynthesis is helpful for humans because it involves production of oxygen, essential for human lives.
The given problem is based on the process of photosynthesis and the effect of photosynthesis on humans.
The photosynthesis is the process by which the green plants and other organisms utilize the sunlight to prepare nutrients from carbon dioxide and water.Photosynthesis in plants involve the green pigment known as Chlorophyll, which is responsible for the production of oxygen into the atmosphere.And humans breathe in the oxygen that the plants produce, in return we breathe out carbon dioxide which is what plants breathe in so in total, we both are helping each other.Thus, we can conclude that the process of photosynthesis is helpful for humans because it involves production of oxygen, essential for human lives.
