Speed is distance over time
miles per hour is distance over time
so if it averaged 420 miles an hour
is it not 420 miles per hour?
perhaps i am misunderstanding something?
Answer:
( x-2)^2 + ( y+1) ^2 = 25
Step-by-step explanation:
The equation of a circle is
( x-h)^2 + ( y-k) ^2 = r^2 where ( h,k) is the center and r is the radius
The center is ( 2,-1) and the radius is the difference from the center to a point on the circle
(2,4) and (2,-1)
since x is the same the radius is (4- -1) = 5
( x-2)^2 + ( y--1) ^2 = 5^2
( x-2)^2 + ( y+1) ^2 = 25
The lines have to be the same
Answer:
4.4
Step-by-step explanation:
10/4=2.5
11/2.5=4.4
Answer:
MN=5.5
Step-by-step explanation:
Thales theorem : MJ/LK = MN/ML = JN/JK
So: MN= (JN*ML)/JK
