Answer:
Step-by-step explanation:
Assuming a perpendicular line(apotherm) is extended from the midpoint of the polygon to the midpoint of one of its sides, then we can determine the length of the apotherm by applying Pythagorean theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Let a represent the apotherm
Hypotenuse = 4
Apotherm = a
Opposite = a(apotherm = length of each side/2)
Therefore,
4² = a² + a²
16 = 2a²
a² = 16/2 = 8
a = √8 = 2√2
The formula for determining the area of a polygon is expressed as
Area = a² × n × tan 180/n
Where n represents the number of sides of the polygon.
n = 6
Therefore,
Area = (2√2)² × 6 × tan(180/6)
Area = 48 × tan 30
Area = 27.2
Answer:
The critical value of F for this situation is 2.975.
Step-by-step explanation:
A test is being performed to determine if a particular drug, smartozine, affects maze learning in rats.
The groups are divided as follows:
- Three groups of 8 rats each are injected with one of three different doses of smartozine.
- The fourth group of 6 rats is injected with a saline solution as a control.
So, there were in total <em>k</em> = 4 groups with <em>n</em> = 30 rats.
The significance level of the test is, <em>α</em> = 0.05.
Compute the critical value of <em>F</em> as follows:
*Use the <em>F</em>-table.
Thus, the critical value of F for this situation is 2.975.
Answer:
x^2y^2 +9xy^2-xy-27y-6
Step-by-step explanation:
(xy+9y+2) (xy-3)
Each term of second bracket will be multiplied with the terms of first bracket
= xy(xy+9y+2) -3(xy+9y+2)
= x^2y^2+9xy^2+2xy-3xy-27y-6
=x^2y^2+9xy^2-xy-27y-6
