I think 3 is 4) 3/4, not sure about 4 though sorry
F(x) = 5x - 6 and g(x) = x^2 - 5x + 6
(f - g)(x) = 5x - 6 - x^2 + 5x - 6 = -x^2 + 10x - 12
(f - g)(x) = -x^2 + 10x - 12
If they meet after 8 hours, then the sum of their average speeds is 600/8=75 km per hour. If one is 5 km per hour faster than the other, then if we set the speed of the slower man to x, we have:
2x+5=75
So:
2x=70
x=30
The fastest man is 5 km per hour faster than the slower, so he travels 35 km per hour.
Answer:
In basic mathematics, pi is used to find the area and circumference of a circle. Pi is used to find area by multiplying the radius squared times pi. So, in trying to find the area of a circle with a radius of 3 centimeters, π32 = 28.27 cm.
According to the Ti 83:
MAD for Dataset 2 is 1.4444
And the ratio is 5/4
