Answer:
(x+1)² + (y-4)² = 10
Step-by-step explanation:
The diameter of a circle has the endpoints at (2,3) and (-4,5).
Therefore, the length of the diameter is given by
= 2
Hence, the radius of the circle is √10.
Now the midpoint of the line joining (2,3) and (-4,5) will be the center of the straight line.
Hence, the center will be at (
Therefore the equation of the circle is
(x+1)² + (y-4)² = (√10)²
⇒ (x+1)² + (y-4)² = 10 (Answer)
Answer:
x = 9.9
y= 11
Step-by-step explanation:
using sin(45)21 = 29.698
3x = 29.698. Divide both sides by 3
x = 9.899. Round to 9.9
In a Right triangle with 45° angles, the legs of the 90° angle are equal. Given 21,
to find the value of y, the equation is
2y -1 = 21. Add 1 to both sides
2y = 22. Divide both sides by 2
y = 11
Writing it as a decimal would be 3.85 you just divide it
Answer:
3.5x + 2.50y = 1237.50
425 = x + y
Step-by-step explanation:
number of adult tickets: x
number of student tickets: y
3.5x + 2.50y = 1237.50
( value of adult ticket [3.50]* number of adult tickets [x]) + (value of student ticket [2.50] * number of student tickets [y]) = total value (1237.50)
425 = x + y
(number of adult tickets [x]) + (number of student tickets [y]) = total (425)
The answer is B
