The standard form of the equation of a circle of radius r, with (assuming centre h, k) is given as:
(X-h)^2 + (y-k)^2 = r^2
As we are required to write an equation in standard form for the circle with radius 9 centred at the origin.
Centre(h,k)=(0,0), r=9
Substituting these values into the standard form of the equation of a circle given above:
(X-0)^2 + (y-0)^2 = 9^2
X^2 + y^2 =81
The standard form is x^2 + y^2 =81
I’m pretty sure this is right
Answer:
see explanation
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 6)² + (y + 1)² = 40 ← is the equation of a circle in standard form
centre = (6, - 1) and r = = 2
Answer:
Residual = Observed Value - Predicted Value
A residual plot is a graph that shows the residual values in the vertical axis and the independent variable or values of x in the horizontal axis. So the coordinates would be (x, corresponding residual of x)
The points in a residual plot of the data based on the table will be:
(1,-0.4)
(2,0,7)
(3,-0.2)
(4,-0.6)
Step-by-step explanation:
It would be a straight line
Answer:
Your answer would be 26.64cm.
A step-by-step explanation for you, peabrain:
For all four sides:
1.8cm x 2.7cm = 4.86cm
4.8cm x 4 sides = 19.44cm
For the top and bottom:
1.8cm x 1.8cm = 3.6
3.6cm x 2 sides = 7.2cm
For the complete LSA (lateral surface area):
19.44 + 7.2cm = 26.64cm
Do not forget to round, if that is in your homework instructions :-)!
