1 It is one because we asume that there needs to be an x. If there is no number before the x it is automatically 1x or up 1 over 1<span />
Answer: (-0.4, 6.8)
The graph is attached
Step-by-step explanation:
We can find the axis of symmetry using the formula x = -b/2a
x = - -4/2(-5)
x = 4/-10
x = 0.04
Substitute for x and calculate y
y = 
y = 6.8
Answer:
infinite solutions.
Step-by-step explanation:
they both represent the same equation.
There are infinite points on a st. line.
Answer: 6 cm, V=48π or V=150.8 cm³
It appears the question is asking for the radius, but below I have shown how to find the volume.
Step-by-step explanation:
The radius is half of the diameter. The diameter of the cone of 12 cm. Half of 12 is 6. Therefore, the radius is 6 cm.
The formula to find the volume of a cone is
. Now that we have the radius from above, we can use that to plug into the equation along with the given height.
