Answer:
C (2,-4)
Step-by-step explanation:
You could graph the circle and then graph the points and see...
Or you could them in and see which point makes the left hand less than 4?
So if you wanted to draw it is a circle with center (2,-3) and radius 2.
If you want to do it the other way:
Plug in time!
(2,-5)?
(2-2)^2+(-5+3)^2
0^2+(-2)^2
0+4=4 so not this one
(2,-4)?
(2-2)^2+(-4+3)^2
0+1
1<4 so this one (you can also see this in the drawing:
Answer:
B - 523cm^3
Step-by-step explanation:
Volume of a sphere is
V = 4/3 * π * r^3
V - volume of the sphere
π - 3.142
r - radius of the sphere
We are provided with
π - 3.142
r - 5
Inserting this values to solve for the volume
V = 4/3 * π * r^3
V = 4/3 * 3.142 * 5^3
V = 1.33 * 3.142 * 125
V = 523.67 cm ^3
To the nearest whole number
V = 524 cm ^3
Answer:
b
Step-by-step explanation:
Answer:
a⁴b⁴ - c⁴
Step-by-step explanation:
The difference of squares formula states that (a - b)(a + b) = a² - b². In this case, a = a²b² and b = c² so a² - b² = (a²b²)² - (c²)² = a⁴b⁴ - c⁴.
