1)
area of half of the circle: 628.32
are of parallelogram: 4000
Exact area of shaded: 3,371.68 cm squared.
The answer to the equation under the shape is: A = 4000 - 628.32 π in²
2)
area of both circles added together: 173.18
full area of rectangle: 220.5
Exact area of shaded: 47.32
The answer to the equation under the shape is: A = 220.5 - 173.18 π in²

Answer:
(x, y) ⇒ (-x√3/2 +y/2, -x/2 -y√3/2)
Step-by-step explanation:
The rule for CCW rotation through an angle α is ...
(x, y) ⇒ (x·cos(α) -y·sin(α), x·sin(α) +y·cos(α))
So, for α = 210°, the rule becomes ...
(x, y) ⇒ (-x√3/2 +y/2, -x/2 -y√3/2)
Answer:
See below in bold.
Step-by-step explanation:
The angle below and to the right of 30 degrees = 90-30 = 60 degrees,.
< EAC + 5x + 6x = 180
But m < EAC = the angle found in first line so its 60 degrees.
S0 3x + 5x + 60 = 180
8x = 120
x = 15
So m < CAB = 75 degrees and m < BAH = 45 degrees.
Finally the m < on top left = 90 degrees.
Answer:
Exactly one solution.
Step-by-step explanation:
2x-4y=8
x+2y=4 /*2
<em>2x-4y=8</em>
<em><u>2x+4y=8 (+)</u></em>
4x=16
x=4
4+2y=4
y=0
(x;y)={(4; 0)}
Exactly one solution.
Answer:
x= y-10a/10
Step-by-step explanation:
Multiply 10 by x+a using the distributive property. 10x+10a=y
Subtract 10a from both sides. 10x=y-10a
Divide both sides by 10. 10x/10 = y-10a/10.
Dividing by 10 undoes the multiplication by 10. x=y-10a/10
Divide y-10a by 10.
I hope this helps and I'm sorry if I got this wrong. I tried my best. Thanks for the question :)
