<u>Answer</u>:
The correct option is C : x² + (y +3)² = 9 .
<u>Step-by-step explanation:</u>
We know that the general equation for a circle is ( x - h )² + ( y -k )²= r², Where,
- r is the radius.
- (h , k) is the center.
Let the point be ( 0 , -y) , since it is on negative y axis . And the circle passes through the origin that is (0,0) . Hence the center will be 3 units down the y - axis that is ( 0 , -3) .Hence h will be 0 and y = (-3) .
Now its given that the radius of the circle is 3. So on substituting r = 3 , in standard form we have ,
⇒ ( x -h )² + ( y - k )²= r²
⇒ ( x - 0)² + { y - (-3) }² = 3²
⇒ x² + ( y + 3) ² = 3²
⇒ x² + ( y + 3)² = 9

<u>Hence the correct option is C [ x² + ( y+3)² = 9 ] .</u></h3>

Answer:
7. C. 6
8. H. √34
9. A. (1, 3.5)
10. J. 10
Step-by-step explanation:
7. AB = 2y, BC = 6y, AC = 48
AB + BC = AC (segment addition theorem)
Substitute the above values into the equation
2y + 6y = 48
Solve for y
8y = 48
Divide both sides by 8
8y/8 = 48/8
y = 6
8. Distance between P(2, 8) and Q(5, 3):
Let,
9. Midpoint (M) of segment LB, for L(8, 5) and B(-6, 2) is given as:
Let
Thus:
10. M = -10, N = -20
Distance between M and N, MN = |-20 - (-10)|
= |-20 + 10| = |-10|
MN = 10
Answer:
To find the "?" we can just simply subtract the side of the two rectanges and divide it by two
43.18 - 25.4
=17.7
17.7/2 ( We divide it by two becuz it's the sum of the two "?" height)
=18.8
the height of the "?" On the vertical axis is 18.8
27.94 - 20.3
=7.64
7.64/2
=3.82
this the height of the "?" on the horizontal axis is 3.82
hope this helps
