At a contest for jumping frogs, the flight of the frogs followed a parabolic path. one frog jumped and landed 9 feet from the starting point. when it had traveled a horizontal distance of 6 feet, it was 2 feet off the ground. a) on graph paper, draw a graph that illustrates this information with the frog starting at the origin. b) what was the maximum height reached by the frog? c) what horizontal distance had the frog traveled when it reached its maximum height?

circumference divided by 3.141592654 then timesthe radius twice

step-by-step explanation:

  b:   ∠x = 28.6°, ∠y = 31.2°, ∠z = 120.2°

step-by-step explanation:

this is one of those questions where "test taking skill" is all you need. the only answer that has angles that sum to 180° is the one shown above. the remaining choices do not describe the angles of a triangle.

if you want to do more work than simply adding the offered numbers, you can also check them against the law of sines. it should be true that

  x/sin(x) = y/sin(y) = z/sin(z)

and all of these ratios must be greater than 15, the longest side length.

if you want to solve the triangle from scratch, i'd suggest solving for the largest angle using the law of cosines.

  z² = x² +y² -2xy·cos(z)

  z = arccos((x² +y² -z²)/(2xy)) = arccos(-75.11/149.4) = 120.182°

now you can find y from the law of sines

  y = arcsin(y/z·sin(z)) = 31.242°

i dont understand the question
