Answer : 54
-2(-3^3)
Calculate within parenthesis : (-3^3) = -27
Multiply and divide left to right : -2(-27) = 2*27 = 54
I hope this helps
This is the answer 46.87016903609025
Answer:
<u>Given is the piecewise function</u>
<h3>The first interval</h3>
<u>Domain:</u>
<u>The function</u>
<h3>The second interval</h3>
<u>Domain</u>
<u>The function</u>
- The slope is m = (0 - (-4))/(0 - (-2)) = 4/2 = 2
- The y-intercept is 0
- y = 2x
<h3>The third interval</h3>
<u>Domain</u>
<u>The function</u>
- The slope is m = (0 - 2)/(4 - 0) = - 1/2
- The y-intercept is 2
- y = -1/2x + 2
I'm going to put this into vertex form, which is y=a(x-h)^2+k
To do this, you use completing the square. Start by subtracting 1 from each side
-1+y=x^2+2x
Then, divide b (2) by 2 and square it. Add that number to each side. (normally when you complete the square, you take out the gcf of the right side of the equation before you do this. Then, you would multiply (b/2)^2 by the gcf before adding it to the left side. Since there is no gcf, we do not have to worry about this)
2/2=1
1^2=1
-1+1+y=x^2+2x+1
Next, simplify the left side and factor the right side.
y=(x+1)^2
This is vertex form. a=1, h=-1, and k=0
The vertex is (h,k) so it is (-1,0)

1st Avenue would be more difficult because it’s rise and run is for every one foot forward it is 3 feet up. Meanwhile avenue 16th would start at (3,1) and the rise and run would be for every 3 feet it would go up 1 foot.
