MULTI-STEP PROBLEM A scientist performed an
experiment to study the effects of gravitational

experience twice Earth's gravity, they were
placed in a centrifuge 58 feet long and spun
at a rate of about 15 revolutions per minute.
a. Through how many radians did the people
- rotate each second?
b. Find the length of the arc through which the
people rotated each second

Astudent found the solution below for the given inequality. |x-9|< -4 x-9> 4 and x-9< -4 x> 13 and x< 5 which of the following explains whether the student is correct? -the student is completely correct because the student correctly wrote and solved the compound inequality. -the student is partially correct because only one part of the compound inequality is written correctly. -the student is partially correct because the student should have written the statements using “or” instead of “and.” -the student is completely incorrect because there is no solution to this inequality.
