Answer:
The maximum height of the ball was 2.5 seconds after it was thrown.
For these types of questions you normally do the new amount - original amount / the original. So 1075-620/620 which gives you 73.39%.
Answer:
sec(60) = 2
Step-by-step explanation:
sec(theta) = 1/cos(theta)
theta = 60o
cos(60) = 1/2 = 0.5
sec(theta) = 1/0.5 = 2
Answer:
<h3>5 inches</h3>
Step-by-step explanation:
A can is cylindrical in nature and volume of a cylinder is expressed as;
V = πr²h where;
r is the radius of the cylindrical can
h is the height of the can.
Given parameters
Volume of the can of soup = 20πin³
diameter of the can = 4inches
Since diameter = 2r
radius = d/2 = 4/2 = 2inches
Required parameter.
Height of the can
Substituting the given parameters into the formula to get the height h will give;
20π = πr²h
20 = r²h
20 = 2²h
20 = 4h
Divide both sides by 4:
4h/4 = 20/4
h = 5inches
<em>Hence the heighr of the can is 5 inches</em>
Answer:
0.1667
Step-by-step explanation:
There are 6! ways to arrange the hats. The number of ways for which no guest will receive the proper hat is 5! (since there are 5 wrong hats for the first guest, 4 for the second guest, and so on). The probability that no guest will receive the proper hat is:
![P=\frac{5!}{6!}=0.1667](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B5%21%7D%7B6%21%7D%3D0.1667)
The probability is 0.1667.
