Answer:
x²-6x+y²-4y=-4
Step-by-step explanation:
We know the circle equation stands like this:
(x-a)² + (y-b)² = R²
and (a,b) is center
and R stands for Radius
so in this case:
center = (3,2)
R = 3
So
(x-3)² + (y-2)² = 9
x²-6x+9 + y²-4y+4=9
x²-6x+y²-4y=-4
Answer:
The simplest form of the function is f(x) = x2. The graph is a parabola often called the basic parabola. Notice that the graph is symmetrical about the y- axis. The y- axis is called the axis of symmetry of this function
Answer:
od I'd the correct answer
Using the Pythagoras theorem
8^2 = 5^2 + x^2 where x = 1/2 length of the base
x^2 = 64-25 = 39
x = = sqrt39 = 6.24
so base length = 2*6.24 = 12.5 cm to nearest tenth
