Answer:
let's take
y=0
when y=0,
y=x-1
therefore,
0=x-1
when we cross -1 the other side it becomes a positive. so when y=0, x=1.
Answer:
Midpoint =1.5,1
radius 4.71699
C = 29.623
A =69.865
Step-by-step explanation:
To find the midpoint, add the endpoint coordinates together and divide by 2
M = (x1+x2)/2, (y1+y2)/2
= (-1+4)/2, (5+-3)/2
= 3/2 , 2/2
=1.5,1
Once we know the midpoint, we can find the radius from one endpoint to the midpoint
d = sqrt( (x2-x1)^2+ (y2-y1)^2)
sqrt( (1.5--1)^2+ (1-5)^2)
sqrt(( 1.5+1)^2 + (4)^2)
sqrt( 2.5^2 +16)
sqrt(6.25 +16)
sqrt(22.25)
4.71699
The circumference is given by
C = 2*pi*r
= 2* (3.14) * 4.717
= 29.623
The area of a circle is given by
A = pi r^2
= 3.14 * 4.717^2
=69.865
Answer:
Table B will be the correct one.
Step-by-step explanation:
The general form of a parabola equation is given by y = ax² + bx + c
Now, comparing the given equation y = 7x² ......... (1), we have the values of a, b, and c as 7, 0, and 0.
Again, the y-intercept of the given parabola will be at x = 0. So, putting x = 0 in the equation (1) we get y = 0.
Therefore, the y-intercept will be at (0,0) and the parabola opens up.
So, table B will be the correct one. (Answer)
