Answer:
=−13m−28
Step-by-step explanation:
Let's simplify step-by-step.
2−13m−30
=2+−13m+−30
Combine Like Terms:
=2+−13m+−30
=(−13m)+(2+−30)
=−13m+−28
Step-by-step explanation:
A=P(1+0.084) ^n;

Let the distance traveled by car X be x km
<span>let the distance traveled by car Y by y km </span>
<span>their paths form a right-angled triangle. </span>
<span>Let the distance between them be D km </span>
<span>D^2 = x^2 + y^2 </span>
<span>2D dD/dt = 2x dx/dt + 2y dy/dt </span>
<span>dD/dt = (x dx/dt + y dy/dt)/D </span>
<span>at the given case: </span>
<span>x = 60, y = 80 , dx/dt = 80, dy/dt = 100 </span>
<span>D^2 = 60^2 + 80^2 = 10000 </span>
<span>D = 100 </span>
<span>dD/dt = (60(80) + 80(100))/100 </span>
<span>= 128 </span>
