Answer: and Step-by-step explanation
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(−5,1)(-5,1)
Equation Form:x=−5y=1x=-5y=1
a.
b. For every month the pine tree grows about 0.67 inches.
c. <em> </em>It represents the height of the tree at the moment Ariel started to record the heights.
<h2>
Explanation:</h2>
<h3>PART A.</h3>
In this exercise we have that in July Ariel recorded the height of a pine tree and how quickly it was expected to grow in next several months. From the Table, we can get the following points:
It is obvious that this problem follows a linear equation, so our goal is to find the equation that matches the Table.
The point slope form of the equation of a line is:
Finding (m):
Finally, the equation of the line is:
<h3>
PART B.</h3>
In this case, we have that:
- The x-axis represents the <em>Number of Months </em>the pine tree was expected to grow.
- The y-axis represents the <em>Height of the Tree </em>in inches.
Since the slope o a line is:
Then, this means that<em> every three months the pine tree grows two inches, </em><em>or </em><em>for every month the pine tree grows about 0.67 inches.</em>
<h3>PART C.</h3>
The y-intercept can be found setting . So, from our equation:
So the y-intercept is and<em> represents the height of the tree at the moment Ariel started to record the heights.</em>

Answer: Trigonal planar 120
Step-by-step explanation:
The double bond unit and the two single bonds arrange themselves as far apart as possible in a trigonal planar arrangement. The oxynitrogen ion which is poly atomic is distinctly strange. and there isn't any simple way of working out its shape.
Answer: 142 degrees
Explanation: Since the total angle of rhombus is 360 and
1) 0.000006 In scientific notation = 06x10^-6
2) 5400000. In scientific notation = 5.4x10^6
3) 60 In scientific notation = 6x10^1
4) 0.009 In scientific notation = 9x10^-3
