Answer:

Step-by-step explanation:
A = the area of the region outside the semicircle but inside the rectangle
w = the width of the rectangle or diameter of the semicircle
Since "A" is determined by "w", therefore, "A" is a function of "w" = A(w).
A(w) = (area of rectangle) - (area of semicircle)

Where,
lenght of rectangle (l) = w + 5
width of rectangle (w) = w
r = ½*w = 
Plug in the values:


Simplify





Initial equation:
4a / 2 = 5.2
Multiply both sides by 2:
4a = 10.4
Divide both sides by 4:
a = 2.6
Hope this helps!! :)
Answer:
21 feet
Explanation:
Using pythagorean theorem to find the length of the added length of the bottom.
A^2+B^2=C^2 or 4^2+B^2=5^2 or 16+B^2=25
25-16=9 so B^2 is 9 and the square root of that is 3 so B is 3. Then you add 15+3+3 to get 21.

Answer:
c = 5
Step-by-step explanation:
The graph of
f(x) = 3x² -5x -7
is shifted 2 units to the right by the transformation ...
g(x) = f(x -2)
g(x) = 3(x -2)² -5(x -2) -7
g(x) = 3(x² -4x +4) -5x +10 -7
g(x) = 3x² -17x +15
When this is written as a monic polynomial, it is
g(x) = x² -17/3x +5
The value of 'c' is 5.
