Answer:
0.039
Step-by-step explanation:
Hello,
The graph of y = x² + 1 most certainly is a function.
It is a function because for every value of x, there is only one value of y.
The domain of y = x² + 1 is the set of all real numbers and the range is y ≥ 1.
Answer: The sphere is 0.002548 cm travel up the plane.
Step-by-step explanation:
Since we have given that
Inclination angle = 30°
Translational speed = 0.25 m/s
As we know that

and
Length of solid sphere is given by

So, it becomes,

And 
So, it becomes,

Hence, the sphere is 0.002548 cm travel up the plane.
Answer:
1/4
Step-by-step explanation:
take the negative reciprocal when finding the slope of a perpendicular line.
So, -4 can be written as -4/1
flip it to make -1/4
and remove the negative to make 1/4
