Answer:
172.05 Rounded to 172.1
Explanation:
Using the following formula for the area of a regular pentagon
[tex]A=\frac{1}{4} \sqrt{5(5+25)}a^2[/tex]
[tex]A=\frac{1}{4} \sqrt{5(5+25)}10^2[/tex]
The Area of a regular pentagon will be "172.1 cm³". To understand the calculation, check below.
Regular PentagonAccording to the question,
Side length (a) = 10 cm
We know the formula,
Area of Pentagon = [tex]\frac{1}{4} \sqrt{5(5+25) a^2}[/tex]
By substituting the values, we get
= [tex]\frac{1}{4} \sqrt{5(5+25) (10)^2}[/tex]
= [tex]\frac{1}{4} \sqrt{5(30) 100}[/tex]
= [tex]\frac{1}{4} \sqrt{150\times 100}[/tex]
= 172.05 or,
= 172.1 cm³
Thus the above answer is correct.

in an experiment exploring the effects of sleep deprivation on memory, the factor of memory would be the...
a.) independent variable
b.) confounding variable
c.) dependent variable
d.) hypothesis
e.) control group
Answer:
Dependent variable
Explanation:
Memory is the dependent variable in this context, since the researcher is trying to test the effect of sleep deprivation (independent variable) on memory (dependent variable). Thus, the variation of the experimental treatment would be applied to the sleep deprivation - perhaps by using a control group (people who did not experience sleep deprivation), or creating different sleep deprivation length to test if there are differences in the quality of memory encoding, storage, or retrieval.
