I understand how to find the equation of a tangent and a normal line at a given point by using the first derivative, and I know how to find the distance from x,y to 2,1 using the distance formula, but I don't see how to put it together. The book says: Use the distance formula ^2 = + ^2 and...

A state police officer is chasing a car he believes is speeding. The officer is traveling at 70mph to try and catch up with the car. But he can't say later that the other car was going 70mph because the driver could ask, "If we were going the same speed, how did you catch up? Obviously I was going...

I have to find the slope-intercept of an equation... 1. slope=2 passes through (1,5)... 2. passes through (-1,-5) and (3,2) 3. passes through (0,3) and is perpendicular to a line whose equation is y-7x=4?

Is critical distance measurement based on the literal distance from a trap to the vent stack, or the total length pipe from the trap to the vent? In other words, if the trap is 4 feet from the vent, but the drain pipe from the trap to the branch that has the vent connected to it is 10 feet, is the...
