List the four types of organic macromolecules. Provide specific molecular examples of each.
Answer:
The ball will be 84 feet above the ground 1.125 seconds and 4.5 seconds after launch.
Step-by-step explanation:
Statement is incorrect. Correct form is presented below:
<em>The height </em>
<em> of an ball that is thrown straight upward from an initial position 3 feet off the ground with initial velocity of 90 feet per second is given by equation </em>
<em>, where </em>
<em> is time in seconds. After how many seconds will the ball be 84 feet above the ground. </em>
We equalize the kinematic formula to 84 feet and solve the resulting second-order polynomial by Quadratic Formula to determine the instants associated with such height:
![3+90\cdot t -16\cdot t^{2} = 84](https://tex.z-dn.net/?f=3%2B90%5Ccdot%20t%20-16%5Ccdot%20t%5E%7B2%7D%20%3D%2084)
(1)
By Quadratic Formula:
![t_{1,2} = \frac{90\pm \sqrt{(-90)^{2}-4\cdot (16)\cdot (81)}}{2\cdot (16)}](https://tex.z-dn.net/?f=t_%7B1%2C2%7D%20%3D%20%5Cfrac%7B90%5Cpm%20%5Csqrt%7B%28-90%29%5E%7B2%7D-4%5Ccdot%20%2816%29%5Ccdot%20%2881%29%7D%7D%7B2%5Ccdot%20%2816%29%7D)
,
The ball will be 84 feet above the ground 1.125 seconds and 4.5 seconds after launch.
