Answer:
5 seconds
Step-by-step explanation:
Suppose the front parts of the trains meet at point A. Since both are the same length and traveling the same speed, each will pass point A in time ...
time = distance/speed
time = (1/18 mi)/(40 mi/h) = (1/720 h) × (3600 s)/(1 h) = 5 s
That is, the rear part of each train will be at point A 5 seconds after the front part.
The rear parts will pass each other 5 seconds after the front parts meet.
Answer:
0.0031
Step-by-step explanation:
31/10000=0.0031
you divided by 10000 and it has four zeroes so you should have four numbers after 0

Answer:
x²+y²=16
Step-by-step explanation:
the general equation for a circle is given as :
(x−h)²+(y−k)²=r²
where (h, k) is the coordinate of the center of the circle and r is the radius
in this case h=0, k=0 and r = 4
equation becomes
x²+y²=4²
or
x²+y²=16
<h2>Answer </h2>
negative
<h2>Explanation </h2>
Let's find the slope of our line using the slope formula:
where
is the slope of the line
are the coordinates of the first point on the line
are the coordinates of the second point
From the graph we can get the points (-2, 1) and (2, -1), so , , , and . Let's replace the values in our formula to find :
The slope of the graph of the linear function is ; since is a negative number, the slope of the graph is negative.
