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.
I will assume you meant D(x)=23(1.0032)^x, if so:
The growth rate as a percentage is 100(.0032)=0.32% (about 1/3 of 1%)
Answer:
decrease by 35%
Step-by-step explanation:
0.65 is only 65% of a whole number, so it decreases the original number by 35%
Internal angles sum: 180(sides-2) = 180
5x = 180 - (48 + 90 + 17)
x = 25/5
x = 5
answer: 5
proof:
(90 + 48) + (5(5)+17) = 180
