D they are supplementary. because when you add them together they equal 180 degrees
The number of boxes at 3 hours from the opening can be written as:
The term 52 * 3 represents the number of boxes produced in the 3 hours, so b is the initial stock.
As the sum of the boxes produced and the initial stock is 404, b is equal to 248.
To complete the table we use the relation:
Replacing the values for x, we can find the value of y:
Answer: the initial stock is 248 boxes.
I am assuming from What I have found is that a is the base , b is angle between a and x and x is the hypotenuse .
So we know that
cos θ =base/hypotenuse
here θ = 3π/8 =67.5 degree
cos 67.5 =0.38268
so
0.38268=a/x
x=25/0.38268
x=65.32873
I'm certain that part b is essentially the same question as a but it asks for the exact amount of difference in distance which is 28 kilometers. Your estimate would be reasonable since there is no major difference between the estimate and the actual difference.
ans C. the scatter plot has a cluster with a domain from 2 to 4
