Answer:
There is 25 1/8 inches left
Step-by-step explanation:
We have a board that is 38 3/4 inches
We cut away 13 1/4
38 3/4
-13 1/4
-----------
25 2/4
The saw takes 3/8
25 2/4
- 3/8
-------------
Get a common denominator of 8 2/4 * 2/2 = 4/8
25 4/8
- 3/8
-------------
25 1/8
There is 25 1/8 inches left
Answer:3/5
Step-by-step explanation:
Hello,
tan KLJ=6/8=3/4
=> mes angle KLJ=36.8698976558...°≈36.87 °
Answer B.
Given that the graph shows tha the functión at x = 0 is below the y-axis, the constant term of the function has to be negative. This leaves us two possibilities:
y = 8x^2 + 2x - 5 and y = 2x^2 + 8x - 5
To try to discard one of them, let us use the vertex, which is at x = -2.
With y = 8x^2 + 2x - 5, you get y = 8(-2)^2 + 2(-2) - 5 = 32 - 4 - 5 = 23 , which is not the y-coordinate of the vertex of the curve of the graph.
Test the other equation, y = 2x^2 + 8x - 5 = 2(-2)^2 + 8(-2) - 5 = 8 - 16 - 5 = -13, which is exactly the y-coordinate of the function graphed.
Then, the answer is 2x^2 + 8x -5
the answer is A, sorry if you can't read it quite well
