Given the vertex of the parabola at point (2, -3):
The quadratic function in vertex form is:
f(x) = (x - 2)^2 - 3
where the vertex (h, k) is the minimum point = (2, -3).
A scale factor of 4. This is a simple dilation problem.
It should be 8473x 38473 93
066666666666667.
I did that question before
Answer:
Step-by-step explanation:
A)
d = r* t Divide both sides by t
d/t = r
r = d/ t
B)
d = 800000
t = 4 hours
r = 800000 / 4
r = 200000 meters/hour
C
r = 200000 meters / hour * [ 1 km / 1000 meters]
r = 200 km / hr
D
I imagine you are more familiar (especially if you live anywhere but the states) with 200 km/ hour. I am very doubtful that any bird can keep that up for 4 hours. 200 km / hour is equal to about 125 miles / hour. There are few places that will allow a car to travel at that speed. You should be using km/hour because you (should) be more familiar with the units.
