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:
(1)
By Quadratic Formula:
,
The ball will be 84 feet above the ground 1.125 seconds and 4.5 seconds after launch.
Answer: 24 in³
Step-by-step explanation:
You know that the dimensions of the box are:
3 inches.
4 inches.
2 inches.
As each face of the cardboard box is a rectangle, you can conclude that it has the form of a rectangular prism.
Therefore, to calculate the volume of the box, you must multiply the dimensions given in the problem.
Therefore, you obtain that the volume of the box is:
Answer:
Step-by-step explanation:
If you want to make
into a perfect square binomial, take half the linear term, square it, then add it to both sides. Our linear term is 12. Half of 12 is 6, and 6 squared is 36.
The value that makes this a perfect square binomial is 36.
Writing the expression as a square of the binomial is:
