Answer:
none
Step-by-step explanation:
any value on y cancel 4y and then we will have -12=12 which is not true.
That is words not question. lol i feel u
Set the equations to equal each other:
-2x²+1=-2x+1
Solve for x:
-2x²+1=-2x+1
-2x²+2x+1=-2x+2x+1
-2x+2x+1-1=1-1
-2x²+2x=0
2x (-x+1)=0
2x=0 and -x+1=0
2/2x=0/2 -x+x+1=0+x
x=0 1=x
There are two solutions, x=0,1
Vertex = (0, 0)
focus = (-2, 0)
p = -2 - 0 = -2
Required equation is (y - k)^2 = 4p(x - h); where (h, k) = (0, 0), the vertex
(y - 0)^2 = 4(-2)(x - 0)
y^2 = -8x
Required equation in standard form is x = -1/8 y^2
Answer:
(if its a true or false question) True
Step-by-step explanation:
<u>We know-</u>
<u>Area of a circle = </u>
A=(π)r2
<u>Circumference of a circle = </u>
C=2(π)r
<u>Where pi is a constant and r is the radius of the circle.</u>
<u>Using these two formulas we can express A in terms of C as follows:</u>
<u />
c2=[2(π)r]2
⇒ c2=4[(π)2]r2 ⇒ c2=4(π)[(π)r2]
As (π)r2=A ⇒c2=4(π)A
<u>Therefore:</u>
A=c2/4(π)
