We know that the area of a semicircle = 1/2(πr^2)
r = the radius
We also know that the area of a rectangle = xy
x = width
y = length
In our problem,
r = w
x = w
y = w + 5
A(w) = w(w + 5) - 1/2(πw^2)
Let's simplify the right side of the function.
A(w) = w^2 + 5w - 1/2πw^2
Answer:
- 4
Step-by-step explanation:
Step 1:
4 ( 2 - w ) + w = 20 Equation
Step 2:
8 - 4w + w = 20 Multiply
Step 3:
8 - 3w = 20 Combine Like Terms
Step 4:
- 3w = 12 Subtract 8 on both sides
Answer:
w = - 4

Answer: If you plot a point in the y-axis at -6, you can plot two more points by using the slope "rise over run" Then draw a line connecting the points.
The coordinate of the y intercept is (0.-6) To find the first x values of the first 2 coordinates, add 1 then 2 to 0. To find the y values, add 2 then 4 to the -6
Step-by-step explanation:
From -6 go up 2 over 1 and plot at (1, -4 ) then up 2 over 1 again to (2, -2)
The x- intercept will be at (3,0)
Answer:
Step-by-step explanation:
2/3 x - 4 = - 92
add 4 to both sides
2/3 x = - 88
multiply both sides by 3
2 x = - 264
divide both sides by 2
this is ur answer
Good luck
Hope this helps!
