2010-2011 TMSCA TEST 4

[sxk1693]

11M-7. A football field's length was accurately measured to be 99 yd 2 ft 8.5 in.. What is the percent error? SD.

11M-38. A quarterback throws a 50 yd pass caught by a receiver on the run. If the maximum vertical height of the football trajectory was 8 yards above the release point, what was the football's initial velocity?

11M-40. There is a circle with an isoceles triangle inscribed in it. Two of the sides both have a length of 1.39. The radius of the circle is 0.731. The question asks to find the third side of the triangle. Hope that's enough info/

11M-60. Cant describe. If anyone has the test, can you look at the problem.

Those are all the ones I don't know how to do from #1-65.
I only missed 3 NC's...But I spent 20 minutes doing them :(.

I can't find the test in downloads, but I will give these a shot. What is M? I hope I don't mess up, because I am working without a key.

7. Just search percent error.

For the SDs I would guess 3, but someone else could answer that part.

38. Projectile motion. Might be a better way to do it, but I just use a handful of equations.

I haven't done this type of problem in awhile if the answer is something else please let me know.
40. Big circle little triangle with two sides given and R. Draw the radii from the center to the vertices of the triangle. That is one method if you want to see it worked: http://www.algebra.com/algebra/homework ... 88780.html
Basically system solve:

double to get whole bottom

I would just use this though, because I solve all circle problems using only two formulas R=a*b*c/4k

60. Link and maybe

No guarantees as to accuracy, please post answers in the future or a link to the test.

I really need to learn how to format my latex to not look so lousy....
Edit: Did the projectile motion problem in yard not feet....
