To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
Answer:
0
Step-by-step explanation:
because we can't multiply anything by 0.
is like saying 0×0×0×0=0
Hope this helps :D
Answer:
5 m
Step-by-step explanation:
The volume (V) of a square based pyramid is
V = Ah ( A is the area of base and h the height ), thus
A × 12 = 100, that is
4A = 100 ( divide both sides by 4 )
A = 25
Hence s² = 25 ← s is the side of square base
Take the square root of both sides
s = = 5
Answer:
The graph should be stretched rather than become narrower.
Step-by-step explanation:
To figure this out, just create some example points.
At x = 0, your y-value will always be 0. But if you were to plug in the value 1, you would get a y-value of 1 in y=x^2, but a value of 0.5 in y=0.5x^2. If you were to plug in a value of 2, you would get a value of 4 in y=x^2, but a value of 2 in y=0.5x^2.
If you continue this pattern for a few more points, then plot them, you will see that adding a coefficient of 0.5 simply stretches the graph
The answer is 180 hope this helps
