Answer:
11.25 ft/sec
Step-by-step explanation:
Given that a jogger runs around a circular track of radius 55 ft.
. Let (x,y) be her coordinates, where the origin is the center of the track.
Then we know x,y satisfies the equation of the circle as
Let us differentiate this implicit function with respect to t
At this point, dx/dt 15 and x=33. y =44
Substitute to have
dy/dt = 11.25 ft /s
Answer:
648
Step-by-step explanation:
We know that
total toppings=15
<span>meat toppings=5
</span>
<span>The first person has a
5/15 chance of getting a meat topping.
The second person has a
4/14 chance because there are no repeats,
The third person would have a
3/13 chance.
Since there are three multiply
5/15 * 4/14 * 3/13.=60/2730
</span>60/2730-------> divide by 30 both members------> 2/91
the answer is
2/91
