Answer:
4.5
Step-by-step explanation:
1000000 times larger
Step-by-step explanation:
2x10^2 is 200.
2x10^8 is 200000000
2x10^8 is 1000000 times larger that 2x10^2
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:
E
Step-by-step explanation:
First lets understand what a quarter to 4 is, a quarter to 4 is 15 minutes before the stated hour. This mean it is currently 3:45.
3:45 + 30 minutes = 4:15
4:15 + 2 hours = 6:15.
The game ends at 6:15
