Answer:
two triangles, the top of one figure with the bottom of the other figure, 8 and 4
Step-by-step explanation:
I am not sure if it's right but I hope it is!
Answer: A. 37 feet
Step-by-step explanation:
1. You can find the x value of the vertex of the parabola as following:
![x=-\frac{b}{2a}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7Bb%7D%7B2a%7D)
2. Substitute values:
a=-16
b=45
![x=1.40](https://tex.z-dn.net/?f=x%3D1.40)
3. Substitute the vaue obtained into the equation given in the problem. Therefore, you obtain the following result:
![h=-16(1.40)^{2}+45(1.40)+5\\h=36.64](https://tex.z-dn.net/?f=h%3D-16%281.40%29%5E%7B2%7D%2B45%281.40%29%2B5%5C%5Ch%3D36.64)
4. To the nearest foot:
![h=37ft](https://tex.z-dn.net/?f=h%3D37ft)
Answer:
Dilation by a scale factor of 2 followed by a reflection over the y axis.
Step-by-step explanation:
The Y-axis is the vertical axis. So that cancels out the two about the x-axis. Then I counted the length of both triangles bases. Luckily for this one their bases aren't tilted but just flat. The big one is 6 and the small 3. Since it is going from one to the other you must find what number completes their equation. 3x = 6.

So that's how I got the last part of the problem
Sorry if this doesn't make sense. It seems just like ramble but it should help.
Answer:
$ 14.00
Step-by-step explanation:
10 · 1.75 = 17.50
17.50 · .20 = 3.5
17.50 - 3.50 = 14.00
