Step-by-step explanation:
A=140sq. units
Answer:
Step-by-step explanation:
52√3 ft²
Answer: k= 19,800
Step-by-step explanation:
It’s right on edge
For this case, the first thing we must do is define variables.
We have then:
n: number of journals.
We now write the equation for the profits.
We have then:
P (n) = (6-1.50) n - 600
Rewriting:
P (n) = 4.50n - 600
Answer:
An equation that represents the profit function of the newsstand is:
P (n) = 4.50n - 600
Answer:
720/1681
Step-by-step explanation:
First quadrant so everything is positive for a trig function of just the angle. I would suggest just drawing a right triangle using tan(x)=40/9 (opp/adj). Find the hypotenuse which is sqrt(40^2+9^2)=sqrt(1600+81)=sqrt(1681)=41. So sin(x)=40/41 and cos(x)=9/41.
Therefore sin(2x)=2sin(x)cos(x)=2(40/41)(9/41)=720/1681
