Step-by-step explanation:
The directrix of the parabola is the horizontal line with the eqaution The focus of the parabola is at point (-4,10), than the axis of symmetry of the parabola is the perpendicular line to the directrix passing through the focus. Its equation is
The distance between the directrix and the focus is so
and the vertex is at point
Parabola goes in positive y-direction, hence its equation is
where is the vertex, so the equation of this parabola is
Answer:
Both will leave their homes to meet on time at 9 am
Step-by-step explanation:
Given as, Distance between Jack and Jill = 126 km
Speed of Jack rides = 18 kilometers per hours
Speed of Jill rides = 24 kilometers per hours
Let the distance travel by Jack = x km
And the distance travel by Jill = (126 - x ) km
Time taken by Jack and Jill = T hours
Now , Distance = Speed × Time
So, x = 18 × T
And 126 - x = 24 × T
Or, 126 - x = 24 ×
Or, 126 - x = x ×
Or, 378 - 3x = 4x
Or, 378 = 7x
i.e x = = 54 km
And distance travel by Jill = 126 - 54 = 72 km
So, time taken by Jack = =
Or, Time taken by Jack = 3 hours
Similarly Time take by Jill = = 3 hours
∵ Both Jack and Jill will take 3 hours to meet at 12 : 00 pm
Hence, Both will leave their homes to meet on time at 9 am Answer
