I don't think you copied it correctly, but I'll assume that you did.

y = 4x³ - 2x² + 5('x' to the -3.7 power) - 6

"y-prime" (the first derivative) = 12x² - 4x - 18.5('x' to the -4.7 power)

My wife and I are Racing around a 400m track going opposite directions. I am running at 8 m/s and she has a head start of 50 met

Vlad [161]

Answer:

They both meet after 27 s.

Step-by-step explanation:

Length of track = 400 m

speed of man, v = 8 m/s

speed of woman, v' = 5 m/s

Woman is 50 m ahead of man.

Let the time taken to meet is t.

Let the man covered a distance d in time t o the woman covered a distance 400 - 50- d.

$\frac{d}{8}=\frac{400-50-d}{5}\\\\5 d = 8 (350-d)\\\\13 d = 2800\\\\d = 215.4 m$

The time taken is

$t=\frac{215.4}8}\\\\\\t=27 s$
