Question 228506: Brenda the Brave sets off to climb a mountain which is 12,000 feet high. She plans to climb 3000 feet each day, before taking overnight rests. A mischievous mountain spirit, however, decides to test Brenda's resolve. Each night, Brenda’s sleeping bag, with her soundly asleep in it, is magically moved 2000 feet back down the mountain, so that when Brenda awakes in the morning she finds herself only 1000 feet higher than she was the morning before! Not one to give up, Brenda eventually succeeds. But how many days does it take her to reach the summit? Give an explanation with your answer

Question 230225: Can you help with this question?
An athelete whose event is the shot put releases a shot. When the shot whose path is shown by the graph is releases at an angle of 45 degrees, its height, f(x), in feet, can be modeled by f(x)=-0.02x^2+1.0x+6.5, where x is the shots horizontal distance, in feet, from its point of release.
a. Where is the maximum height of the shot and how far from the point of release does this occur
b. What is the shots maximum horizontal distance to the nearest tenth, of a foot or the distance of the throw.
c. From what height was the shot released?

Question 231183: Please help me with this question: "M is the midpoint of YZ. If YM=x+3 and YZ=3x-1, find MZ.
We know ym = 1/2(yz) Plug in teh numbers we know
x + 3 = 1/2(3x - 1) Solve
x + 3 = 1.5x - .5 Subtract 1.5x on both sides and subtract 3.
-.5x = -3.5 Divide -.5 on both sides
x = 7 Plug 7 into x + 3 and you have 10 = YM since It is the midpoint then MZ is also 10
