An arrow is shot upward, with an initial velocity of meters per second, at an angle of with respect to the horizontal. The arrow is shot from a height of meters above the ground. The horizontal distance from the starting point and the height above the ground of the arrow seconds after it is shot are given by the parametric equations below. Here is the initial velocity, is the initial angle with respect to the horizontal, and is the initial height. Use the equations to answer the following questions. (a) How long is the arrow in the air before it first touches the ground? Do not round any intermediate computations. Round your answer to the nearest hundredth.
(b) What is the horizontal distance the arrow travels before it first touches the ground?

step-by-step explanation:

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
