Answer:
(x - h)^2 + (y - k)^2 = 3^2
Step-by-step explanation:
The most general standard form here is
(x - h)^2 + (y - k)^2 = r^2. Since we know the center is at (-2, -3), we rewrite this equation as
(x + 2)^2 + (y + 3)^2 = r^2.
Note that the center (-2, -3) and the point (-2, 0) lie on the same vertical line, and that the vertical distance from the center to this point is 3. This is also the radius of the circle. Thus, the equation of this circle is:
(x - h)^2 + (y - k)^2 = 3^2
- f (x) = 3x² + x
- Find f (-5).
Given,
Now, we have to find f (-5). To find this, we just need to substitute -5 in the place of x.
So,
Answer:
32 school hrs in a week.
Step-by-step explanation:
The reduction percentage =
80 x 0.80 = 64 (hrs)
The distribution =
64/2 = 32hrs
Answer: The answer is y=-4/3x-10.
Step-by-step explanation:
-6=-4/3(-3)+b
-6=4+b
-4 -4
-10=b
y=-4/3x-10
Answer:
512ft³
Step-by-step explanation:
If the cube its sides of all 8 feet, then the length, width, and height is 8 feet. Then, multiply 8 by 8 you get 64 and then multiply 64 by 8 to get 512.
