Answer:
She has 42 pieces of wood each of 1 inch of length.
Step-by-step explanation:
Amy has 42 inches piece of wood.
She has to cut an inch.
After cutting pieces of inch each she counts the pieces to be 42.
Mathematically
Total length / unit lenght = Number of pieces
42 inches/ 1 inch= 42 pieces.
She has 42 pieces of wood each of 1 inch of length.
C. All of the above. Both formulas represents in calculating the slope.
<u>Step-by-step explanation:</u>
The slope(m) can be identified by the formula rise over run.
i.e.
.
Rise is how much the line gone vertically ( y-axis) from the origin.
Run is how much the line gone horizontally (x-axis) from its origin.
∴ Rise = 
And Run =
.
⇒
.
Thus both equations can be used to find the slope of the line intercept.
If the points are given you can chose them yourself from the graph. Just consider any two points on the line.
Answer:
-x²-2
Step-by-step explanation:
x² = the curve faces upwards
but
-x² the curve faces downwards.
also
the downward curve touches -2 on the y axis.
therefore gx = -x²-2
for this question you would need to utilize ratios to find the side lengths. For example, set up a ratio between the big triangle with the small triangle to find a side length
