I’ll try, hopefully I get it right
The maximum value attained by the function will be 4
4 = 4cos(2x - π)
cos(2x - π) = 1
2x - π = 0
x = (nπ)/2
From x = 0 to x = 2π, n = 1, 2, etc
The equation will yield +4 for odd values of n and -4 for even values of n
Answer:
A. Width = 25 Length = 15
Step-by-step explanation:
Length = L = Width - 10
Width = W
Perimeter of a rectangle
=> 2 (L + B) = 80
=> 2 (W - 10 + W) = 80
=> 2 (2W - 10) = 80
=> 4W -20 = 80
=> 4W -20 + 20 = 80 + 20
=> 4W = 100
=> 4W/4 = 100/4
=> W = 25
Width = 25
Length = 25 - 10 = 15
So, the answer is A.
<h3>Answer:</h3>
4 m
<h3>Explanation:</h3>
If we let h represent the height of the sail, then its width is h/2. The area of the sail is given by ...
... A = (1/2)wh
Filling in the given information, we have
... 4 m² = (1/2)(h/2)h
... 16 m² = h² . . . . . . multiply by 4
... 4 m = h . . . . . . . . take the square root
