<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:
dresses
Step-by-step explanation:
We are given that
Lucy sews dress in 3/4 hours=
of dress
Lucy sews at constant rate.
We have to find the number of dresses sewed by Lucy in hour.
To find number of dress sewed by Lucy in 1 hour we will use unitary method.
By using unitary method
Lucy sews in 3/4 hours=
dress
Lucy sews in 1 hour=
Lucy sews in 1 hour=
Lucy sews in 1 hour=
dresses
Hence, Lucy sews
dresses in 1 hour.
Answer:
1.178
Step-by-step explanation:
(for Jamal)
5 x 2 = 10
6 x 3 = 18
7 x 2 = 14
8 x 1 = 8
10 x 1 = 10
Mean: 10 + 18 + 14 + 8 + 10 = 60/9 = 6.6
6.6 - 5 = 1.6 x 2 = 3.2
6.6 - 6 = 0.6 x 3 = 1.8
7 - 6.6 = 0.4 x 2 = 0.8
8 - 6.6 = 1.4
10 - 6.6 = 3.4
<em>Mean Absolute Deviation:</em> 3.2 + 1.8 + 0.8 + 1.4 + 3.4 = 10.6/9 = 1.178
