Answer:
(x + 4)² + (y - 3)² = 49
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 4, 3) and r = 7 , thus
(x - (- 4))² + (y - 3)² = 7² , that is
(x + 4)² + (y - 3)² = 49
Answer:
Im pretty sure the answer is B) f=2.5b
This is completing the square.
So x^2-6x-12=0
Add 12 to both sides so x^2-6x=12
Now take half the x term and square it. Add this number to both sides.
So x^2-6x+9=12+9
Which is the same as (x-3)^2=21
This is answer 2.

Step-by-step explanation:
Answer:
The area of the figure is 86.13
Step-by-step explanation:
First, solve for the area in the triangle using the equation A = h*b/2
We have the height and the base which is 6. Plug in for the equation and solve.
A = 6*6/2
A = 36/2
A = 18
Next, solve the area for the rectangle using the equation A = w*l
The width is 6 and the length is 9. Plug in for the equation and solve.
A = 6*9
A = 54
And finally, solve for the area of the triangle using the equation A = pi*r^2
We know that pi is around 3.14 and the diameter is 6. We know that a diameter is twice the length of the radius, so we can divide the diameter by 2 and get the radius.
r = 6/2
r = 3
Now plug in the equation and solve.
A = 3.14*3^2
A = 3.14*9
A = 28.26
Since this is the area of a full circle, we need to divide the area of it by 2 to get the area of a half circle.
A = 28.26/2
A = 14.13
Next, add them all up and you will get your answer.
18 + 54 + 14.13 = 86.13
Hope this helps.
