Answer:
The distance between them changing after 10 minutes will be 9.553 mph.
Step-by-step explanation:
The paths of two runners cross at a stop sign (O). One runner is heading south at a constant rate of 6.5 miles per hour towards A while the other runner is heading west at a constant rate of 7 miles per hour towards B.
So, after 10 minutes the first runner covers a distance of miles and the second runner covers a distance of miles.
Therefore, after 10 minutes their distance will be miles.
Now, the distance between them is given by
AB² = OA² + OB²
Now, differentiating this equation with respect to time t (in hours) we get
⇒
⇒
⇒ mph.
Therefore, the distance between them changing after 10 minutes will be 9.553 mph. (Answer)
Answer:
<h2>
y+9=-10(x-6)</h2>
Step-by-step explanation:
First you find the slope by setting your y2-y1 over your x2-x1 and that gives you -9-1 / 7-6.
simply that and it gives you -10/1 =-10
then you use the formula y-y1= m(x-x1) . So basically you filling in the blanks
and that gives you y+9=-10(x-6)
