Answer:
gradient = 5
Step-by-step explanation:
you can do this by subbing points into the slope formula or you can just do rise over run
Number of copies made in 1 minute or 60 seconds =44
Number of copies made in 1 second =44/60
1 minute = 60 seconds
4 minutes = 4*60 = 240 seconds
total time = 240 + 45= 285 seconds
Number of copies made in 285 seconds =(44/60) *285 =209 copies
Answer:
6 seconds
Step-by-step explanation:
Total distance between the 2 rear cars =
we are given the ordinary differential equation of dy/dx = 2y+1. The ODE is variable separable which means x and y can be grouped altogether explicitly. In this case, the equation becomesdy / 2y + 1 = dx
1/2 ln (2y + 1) = x + ln Cln (2y + 1) = 2x + ln C2y + 1 = C e 2x y = (C e 2x - 1)/2
The ODE y' + xy = x can be grouped into y' + x(y-1) = 0 'y' / y-1 = -xThis is variable separable
