Step-by-step explanation:
Answer:
Step-by-step explanation:
This is horizontal parabola.
It has a directrix at x=-6.
The vertex is (0,0).
The focus is (6,0)
The equation of this parabola is of the form
Where (p,0) is the focus
By comparison, p=6
Therefore the equation of the parabola is
This implies that
If Nathan does 9 minutes of push ups for 3 days, that's 9 divided by 3, which is 3. (9/3=3) So nathan does 3 minutes of push ups each day, so just multiply each day by 3 to find the correlation between the two.
The Table should look like this:
# of days # of Minutes
1 3
2 6
3 9
4 12
5 15
6 18
7 21
Answer:
Dezias' pensil is 5.11-1.09=4.02 inches long
Paul's pencil is 4.02+2.05=6.07 inches long
Miguel's pencil is 5.11+1.75=6.86 inches long
Combined are 5.11+4.02+6.07+6.86=22.06
The fraction is 22.06/12=1.8383333...
