45% is 45/100, divide that by 5 and you get 9/20
The equation of the circle that passes through the point (0 , 4) and has a center at the origin is x^2 + y^2 = 16.
Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (0 , 4).
radius = distance = √(x2 - x1)^2 + (y2 - y1)^2
radius = √(0 - 0)^2 + (4 - 0)^2
radius= √0 + 16
radius = 4
The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.
(x - h)^2 + (y - k)^2 = r^2
where (h , k) = (0 , 0)
r = 4
(x - 0)^2 + (y - 0)^2 = 4^2
x^2 + y^2 = 16

Answer:
15
Step-by-step explanation:
Take x as how many pounds you need for the 6000 square feet
7 pounds x pounds
--------------- -----------------------
2800 square feet 6000 square feet
7*6000=42000
42000/2800=15
or you could find how many pounds you would need for 1 square feet.
7 pounds .0025 ponds
---------------- -----------------------
2800 square feet 1 square feet
and then you could just multiply .0025 and 6000
so = 15
Answer:
C) x = ½
Step-by-step explanation:
Using the <em>Distributive Property</em> and combining like-terms will give you this:
-12 + 10x = 2x - 8
- 10x -10x
--------------------
-12 = -8x - 8
+ 8 +8
-------------
-4 = -8x [Divide by -8]
½ = x
