Answer:
C. (X-9)^9 + (y+9)^2= 16
D. (X-9)^2 + (y+5)^2= 9
Step-by-step explanation:
The formula for a circle is
(X-h)^2 + (y-k)^2= r^2
where (h,k) is the center of the circle and r is the radius
The 4th quadrant is where x is positive and y is negative
Add r to the y coordinate of the center and if it is still negative, the circle is still completely in the 4th quadrant
A. (X-12)^2 + (y+0)^2= 72
The center is at 12,0 and the radius is sqrt(72) = 6sqrt(2)
This will be positive so it goes into the 1st quadrant
B. (X-2)^2 + (y+7)^2= 64
The center is at 2,-7 and the radius is 8
-7+8=1 so it goes into the 1st quadrant
C. (X-9)^9 + (y+9)^2= 16
The center is at 9,-9 and the radius is 4
-9+4 = -5 so it is completely in the 4th quadrant
D. (X-9)^2 + (y+5)^2= 9
The center is at 9,-5 and the radius is 3
-5+3 = -2 so it is completely in the 4th quadrant
The answer is 11 becauze the pattern works like this - 18÷2=9 20÷2=10 22÷2=11 Basically the X axis being divided by 2 which equals the Y axis (eg: X÷2=Y
Answer:
Prime number: A prime number has factor of only 1 and itself.
Ex: 3: 1 and 3 are the only ways to compose 3.
A whole number that has factors other than 1 and itself is called a composite number.
Ex: 8: the factors of 8 include 1,2,4,8
Circle 5,7,2,19,3,11
Box 18,20,22,16,15,30,26,38,45,10,21,6,14
To determine the prime factorization of a number, you must break down a number into its factors. (im not sure?)
Continute until all of the factors are (im not sure)
Prime factorization is written exponential form (im not quite sure)
30= 2x3x5
30= 2^1 3^1 5^1
24=2 × 2 × 2 × 3
24= 2^3 x 3
sorry idrk if they are all right
