When we use arcsine, we are finding the angle while giving the trigonometric ratio.
Arcsin(u) = theta can be rewritten as:
sin(theta) = u
Sine is opposite over hypotenuse, so u/1 means that the side opposite to theta (the y value) is u, and the hypotenuse is 1.
We can use Pythagorean Theorem to find the adjacent (x value).
1^2 - u^2 = x^2
x = sqrt(1-u^2)
Back to the original question, we are trying to find cos(arcsin(u)). We just solved all the sides for our triangle using arcsin(u). Now we need to do cos(u).
Cosine is adjacent over hypotenuse.
So our answer is sqrt(1-u^2)/1
Or just sqrt(1-u^2)
True. Because two even numbers weather you Add Subtract or Multiply them they will always be Even
She is correct because a negative subtracted by a negative is positive.
Answer:
12
Step-by-step explanation:
collected can=18pound
total can to collect=42
collected can per week=2
now,
42-18 =24
so, remaining cans to collect is 24pound
and,
24/2
=12
so, Rufus have to collect for 12 weeks for 42pound of cans in total
Answer:
option (a) $250
Step-by-step explanation:
Data provided in the question:
Fixed cost = $500
For 100 units produced Total cost = $3,500
For 101 units produced, Total cost = $3,750
Now,
Marginal cost is calculated as:
Marginal cost = 
thus,
Marginal cost = 
or
Marginal cost = 
or
Marginal cost = $250
Hence,
The correct answer is option (a) $250
