Find the dimensions that give the largest area for a rectangle lying evenly between the first and second quadrant. Its base is on the x-axis and its other 2 vertices are above the x-axis and lying on the parabola y = 8 - x^2. I have no idea where to start. Try to explain why I would do a...

A rectangle is inscribed in a semi-circle of radius 10. Find that function that models the area A of the rectangle in terms of its height h. Please show work, I need to see how this is calculated. I already have the answer.

distance d and then another distanc? A car travels along a straight line at a constant speed of 43.0 mi/h for a distance d and then another distance d in the same direction at another constant speed. The average velocity for the entire trip is 33.5 mi/h. (a) What is the constant speed with...

...sprints to a speed of 9.1 m/s? In getting ready to slam-dunk the ball, a basketball player starts from rest and sprints to a speed of 9.1 m/s in 1.7 s. Assuming that the player accelerates uniformly, determine the distance he runs. ________m

One of my HW problems says there is no reaction between a primary Bromoalkane and Methanol. According to a table in my textbook, primary haloalkanes do not react when treated with a poor nucleophile (such as H20). Why is Methanol a poor nucleophile?

Two stones are thrown off a cliff with the same velocity (20 m/s) at the same time. The first stone is thrown at an angle 40 degrees upward from the horizon and the second is thrown 30 degrees downward from the horizon. both are thrown in the same compass direction, only the angles of elevation...

A tight uniform string with a length of 1.80 m is tied down at both ends and placed under a tension of 100 N. When it vibrates in its third harmonic, the sound given off has a frequency of 72.5 Hz. Round to two significant figures. What is the mass of the string?
