Hello :
<span>x-coordinates for the maximum points in the function f(x) = 4 cos(2x − π) from x = 0 to x = 2πis solutions of : f'(x) =0
f'(x) = - 2sin</span><span>(2x − π)
</span>- 2sin(2x − π) =0
sin (2x − π) =0
2x − π = kπ ... k in Z
x=(k+1)π/2....(general solutions in R)
<span>from x = 0 to x = 2π :
</span>k =0 : x = π/2
k=1 : x= π
k=2 : x= 3π/2
k = 3 : x=2π
Remains to be determined whether it is a maximum or minumum
1 worker earns 8/hour for 40 hrs.8 times 40=320 dollars in amount for 1st worker.the 2nd worker has the same 8 hrs for 40 hours therefore the same amounts.320+320=640
as a percentage:640 divided by 2000=0.32
0.32 times 100
=32 percent for both workers.16 percent for only 1 worker<span />
2y^2 = x^2
y = x/sqrt(2)
how?
y = (x^2)/(2y)
y(2y) = (x^2)(2y)/(2y)
Answer:
The dimensions of the rectangle are: Length: 17 centimeters, Width: 11 centimeters.
Step-by-step explanation:
From Geometry we remember that the perimeter (), measured in centimeters, of a rectangle is determined by the following formula:
(1)
Where:
- Width of the rectangle, measured in centimeters.
- Length of the rectangle, measured in centimeters.
If we know that , and , then the value of is:
And the length and the width of the rectangle are, respectively:
The dimensions of the rectangle are: Length: 17 centimeters, Width: 11 centimeters.
