Answer: y = x^2 + 6x+ 9 = 0. (X+3)^2= 0 when x=3. This has one root.
X^2-2x -24 = 0 a= 1 b=-1 and c= -24 x = {-(-1) +/- sqrt((-1)^2 -4 x 1 x (-24)}/2
X = [1 +/- sqrt(97)]/2
Step-by-step explanation:
I'm guessing the answer is B? I tried to isolate r and I got that result. Sorry if it's wrong!
By critically observing the cross-sections of the three-dimensional object I used, a cone is the cross-sectional shape I find most surprising.
<h3>The cross-section of a three-dimensional object?</h3>
In this exercise, you're required to use an online tool to investigate and determine the cross-sections of three-dimensional objects such as pyramids, cylinders, cones, etc., by passing different planes through them.
By critically observing the cross-sections of the three-dimensional object I used, a cone is the cross-sectional shape I find most surprising because rotating the slice around Y produced a circular curve that transitioned into a parabolic curve.

Given:
The radius of the sphere is 6 in.
To find:
The volume of the sphere.
Solution:
We know that, the volume of a sphere is

Where, r is the radius of the sphere.
Putting r=6, we get




The volume of the sphere is 904.78 inches cubed.
Therefore, the correct option is C.
1 hundredth is equal to 0.01 therefore 20 hundredths is equal to 0.2. 1
thousandth is equal to 0.001 therefore 2 thousandths is equal to 0.002.
Clearly these are not equivalent.
