Answer:Explanation: The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

Answer:
C
Step-by-step explanation:
When we talk of rate of change, we talk of the slope of the line
If we had a line;
y = mx + b
m is the slope ( which is the rate of change)
To get the slope of the line, we select any two points on the line and apply the slope formula
m = y2-y1/x2-x1
let us take points (0,0) and (3,9)
m = 9-0/3-0 = 9/3 = 3
The slope here is 3
so from the option, we can see that the third option is the correct answer
9a-4+3a-33=23
9a+3a-29=23
+29 +29
9a+3a=52
-3a -3a
9a=52-3a
9a/9=52/9- 3a/9
a=52/9-1/3a
Answer:
363
Step-by-step explanation:
11x11=121
((11x11)÷2)x4=11x11x2=121x2=242
121+242=363
