Answer:
132.233 ft2
Step-by-step explanation:
Let's call the width of the rectangle 'w' and the length 'x'. So the area of the semicircle is:
And the area of the rectangle is:
If the perimeter of the window is 41 feet, we have:
Now, the equation for the total area of the window is:
To find the maximum area, we can find the x-coordinate of the vertex of the quadratic equation:
So the width that gives us the maximum area of the window is 6.45 feet, and the area will be:
Answer:
90° - COD
Step-by-step explanation:
Because if it's complementary, the mystery angle and COD add up to 90°
Use this equation for all x + given value = 180
Answer:
is the required term.
Step-by-step explanation:
We have been given an arithmetic sequence where we have a common difference which is:
We will use the formula to find the required term:
where, a is first term which is 3 and d is the common difference which is 9
and n =45 which we require to find.
