Answer:
Step-by-step explanation:
The equation of a circle is: 
, where x_1 is the x coordinate of the center, y_1 is the y coordinate of the center, and r is the radius.
In this case, x_1 = -8, y_1 = 14, and r = 4.3589. Plugging these into the equation, we get:
If you want, you can round 4.3589^2 to 19.
Then, the answer would be: .
Hope this helps!
Answer:
ok ok so its the first one at the top(least), then the third one, then the second one, then the fourth one at the bottom(greatest)
Step-by-step explanation:
1= 88/63 least
2= 95/18 third
3=70/27 second
4= 95/4 greatest
Answer:
1. sin and cos 2. complementary 3. sinA = cosB 4. 80° 5. 17
Step-by-step explanation:
1. cofunctions: having the same value at complementary angles
sin θ = cos (90 - θ), <em>or </em>cos θ = sin(90 - θ)
2. complementary: two angles sum to 90°, supplementary: two angles sum to 180°
one of the angle in a right triangle must be a right angle = 90°
180°<em>(sum of angles of a triangle) - </em>90° = 90°<em>(the sum of the other two angles)</em> => which is complementary
3. sinA = cosB
4. cos θ = sin(90 - θ)
=> cos 10° = sin(90 - 10°)
=> cos 10° = sin(80°)
5. sin θ = cos (90 - θ)
=> sin 73° = cos (90 - 73°)
=> sin 73° = cos (17°)
<u>Answer:</u>
The sale price per piece of chicken was $0.69
<u>Step-by-step explanation:</u>
• We have to first calculate the price of 1 piece of chicken when 12 pieces cost $9.48.
Original price per piece = $9.48 ÷ 12
= $0.79
• According to the question the price per piece decreased by $0.10 during the sale.
∴ Sale price per piece = $0.79 - $0.10
= $0.69
