Answer:
The length of the radius of the sphere is 11.0 units
Step-by-step explanation:
we know that
To calculate the radius of the sphere, we can use the distance formula
where
d is the length of the radius
(x_1,y_1,z_1) is the center of the sphere
and
(x_2,y_2,z_2) is one point on the surface of the sphere
we have
substitute in the formula
therefore
The length of the radius of the sphere is 11.0 units

Answer:</h3>
x = 3

Step-by-step explanation:</h3>
Taking the antilog, the equation becomes ...
... 8x/(x^2 -1) = 3
Multiplying by the denominator, you have ...
... 8x = 3(x^2 -1)
Subtracting the left side to put into standard form gives ...
... 3x^2 -8x -3 = 0
This can be factored as ...
... (3x +1)(x -3) = 0
so the values of x that make these factors zero are ...
... x = -1/3 . . . and . . . x = 3
The original equation requires x > 1, so the only viable solution here is ...
... x = 3

We can also solve this graphically to get the same result.
Answer:
22 laps
Step-by-step explanation:
Clara wants to run 5 1/2 miles, and the track is only 0.25 miles long. This is a fairly easy question, you just need to figure out how many times 5 1/2 goes into 0.25, because she wants to run that amount of miles (I could never run that much).
I hope that answers your question so you understand, and I hope you have a great rest of your day! :)
