Area of the shaded region is 1397.46 square feet.
<h3>what is area of shaded region?</h3>
The area of the shaded region is the difference between the area of the entire polygon and the area of the unshaded part inside the polygon. The area of the shaded part can occur in two ways in polygons. The shaded region can be located at the center of a polygon or the sides of the polygon.
We are to find the area of the shaded region. For that, we will divide the figure into smaller shapes, find their areas separately and then add them up.
From the given figure, we can see that there are two semi circles or say one whole circle if we combine them at the ends while 2 rectangles at the top and bottom.
Radius of circle = 
= 17
Area of circle = 
= 
= 907.92 square ft.
Area of rectangles =2×(l×b)
= 2×20×35
= 490 square ft
Then,
Area of the shaded region = 907.92 +490
= 1397.46 square ft
Hence,Area of the shaded region is 1397.46 square ft.

all sides are congruent!:)
Answer:
2. increasing when x > 0
the result of root is a positive number
and since there is no value of neg number in roots so it's increasing when x>0
plus in zero it self has a positive number (0,8)
but u cannot find either it's increasing or decreasing in zero bcoz in first derivative test
when x =0
y= not defined

Answer: (3.46, 3.62)
Step-by-step explanation:
The formula to find the confidence interval for population mean is given :-
, where n = sample size.
= Two-tailed t-value for significance level of 
and degree of freedom df= n-1.
= sample standard deviation.
As per given , we have
mm
s= 0.20 mm
n= 25
Significance level 
Since population standard deviation is not given , it means the given problem has t- distribution.
Two-tailed t-value for significance level of 
and degree of freedom df= 24:
95% Confidence interval for population mean:
Hence, the 95% two-sided confidence interval for the mean glass thickness = (3.46, 3.62)
