Five times Five equals twenty-five.
Step-by-step explanation:
The cartesian graph consists of x and y axes, while the cosine graph is made of and y axes. This means that each value of x has to be converted in to represent a corresponding point in cosine graph.
Thus,
x = cos
or,
For point (1, 0)
y = cos
y = cos(0)
y = 1
Point in cosine graph = (0, 1)
For point (0, 1)
y = cos
y = cos(90)
y = 0
Point in cosine graph = (90, 0)
For point (-1, 0)
y = cos
y = cos(180)
y = -1
Point in cosine graph = (180, -1)
For point (0, -1)
y = cos
y = cos(90)
y = 0
Point in cosine graph = (90, 0)
So, the first thing you want to find out is how many seconds each person adds to the wait time. Find out how many seconds are in 20 minutes.. 20*60=120. 120/150=0.8 seconds. Each person adds 0.8 seconds to the wait time. Now, multiply that by 240.. 240*0.8=192 seconds. Lastly, find out how many minutes 192 seconds is... 192/60=32 minutes.
I hope I did that right! And if I did, I hope that helped!
A rational number is any number that can be represented as a fraction. (7=7/1 or 52 = 26/1 ).
An irrational number is a number like 3.14159 (pi) or anything like that.
