Answer:
x² + y² = 144
Step-by-step explanation:
The general equation of a circle is given as
(x - a)² + (y-b)² = r²
where a and b are the center of the circle along the x and y axis respectively and r is the radius of the circle.
Hence a circle that has its center at the origin and has a diameter of 24 units, we can deduce that the values of a,b are 0,0. Also,
radius = diameter/2
= 24/2
= 12 units
Hence the standard equation of the circle
(x - 0)² + (y - 0)² = 12²
x² + y² = 144
A. is 10! you multiply the scale (2.5) times the length (4)
b. is 6, you divide 15 by 2.5
c. is 5. you do what you did with a but with 2 inches instead of 4
d. is 1.5 you divide 378 by 250

Step-by-step explanation: 210-5=205
41,790+205=41995
Answer:
1/5
Step-by-step explanation:
We can find the slope using the slope formula
m = (y2-y1)/(x2-x1)
= (3-2)/(4 - -1)
(3-2)/(4+1)
1/5
