Step-by-step explanation:
Area of a rectangle is given by:
....[1]
where
A is the area of rectangle
l is the length of a rectangle
w is the width of a rectangle.
As per the statement:
A certain rectangle has an area of 
⇒
Now factor this trinomial :

⇒
⇒
unit square
On comparing with [1] we have;
unit and
unit
Therefore,the length and width of the rectangle are:
unit and
unit
No because you need another angle. angle QRP and TRS are congruent because they are vertical angles. if you add that then you will get ASA which proves congruency
Answer:
V(r) represent the volume of air inside a basketball in cubic units for a given radius r in units
Step-by-step explanation:
we have the function

where
V is the volume of a sphere (dependent variable or output function)
r is the radius of the sphere (independent variable or input variable)
therefore
V(r) represent the volume of air inside a basketball in cubic units for a given radius r in units
Answer: c) increase
Step-by-step explanation:
- A sample is a finite subset of the entire population on which research statistical test regarding his/ her objective .
As the sample size increases it comes closer to the population size, and so converge to a better result of researcher's analysis.
It means the size of the sample is proportional to the power of their statistical tests.
∴ As the size of the sample increases the power of statistical test increases.
Hence, If a research team increases the sample size for a study, the power of their statistical tests will <u>increases</u>.
Therefore , the correct answer is : c) increase
