Answer:
the diameter of a tube is 1 3/4. How much is radius
A parabola with an equation, y2 = 4ax has its vertex at the origin and opens to the right.
It's not just the '4' that is important, it's '4a' that matters.
This type of parabola has a directrix at x = -a, and a focus at (a, 0). By writing the equation as it is, the position of the directrix and focus are readily identifiable.
For example, y2 = 2.4x doesn't say a great deal. Re-writing the equation of the parabola as y2 = 4*(0.6)x tells us immediately that the directrix is at x = -0.6 and the focus is at (0.6, 0)
Answer:
About $3, 333.30
Step-by-step explanation:
If Karen makes $40,000 a year, that means she makes about $3,333.30 a month (12 months in a year, divide 40,000 by 12 to get the answer) this means she can budget about $3,333.30 a month.
(I rounded to make the answer more realistic the full number is 3333.3333333333333333333333333333)
32 = 2x2x2x2x2
99 = 11x3x3
100 = 5x5x2x2
400 = 2x2x2x2x5x5
39 = 3x13
35 = 5x7
80 = 2x2x2x2x5
42 = 2x3x7
5 = 1x5
78 = 2x3x13
