Answer:
This is a fairly straightforward piecewise function. The functions can be determined if you give me the vertex and one additional point of the dip in the graph. I also need 2 points in the green line. I can help you better if you provide me with these details because the pic is not very clear. Hope this helped a little.
Step-by-step explanation:
1) Use the vertex formula y=a(x-h)+k where h and k is the vertex and solve for a with additional point you can plug in.
2) find the green line by using the y=mx+b formula
3) Use the y= some number formula for blue line.
The only two usable numbers that make up 63 are 9 and 7 and 21 and 3 in some form. So that's how you start the question.
(x 9)(x 7) is what you can get. The 2x is very small, so it suggests that 21 and 3 are not the right factors.
You have a plus 2 as the middle term. That is exactly the difference between 9 and 7. That tells you the sign on 9 because it is larger than 7.
(x + 9) ( x 7) is what you have so far. Since 63 is minus, the 7 must be minus. Now what you have is
(x + 9)(x - 7) and that is the final answer.

Answer: $580.38 (Choice B)</h3>
===================================
Work Shown:
A = P*(1+r/n)^(n*t)
A = 500*(1+0.05/4)^(4*3)
A = 580.3772588615
A = 580.38
Answers:
- Cold climates favor mechanical weathering.
- Lower precipitation levels lead to more chemical reactions.
- The chemical reaction rates of minerals are not impacted by temperature.
