The area of the regular octagon is approximately 54 cm2. What is the length of line segment AB, rounded to the nearest tenth?

erastova [34]

Answer:

AB = 3.3 cm

Step-by-step explanation:

The formula to find out area of a regular octagon is given by

$A=2(1+\sqrt{2})a^{2}$

where a is the length of each side of the regular octagon.

Plugin A=54 into the formula

$54=2(1+\sqrt{2})a^{2}$

Divide both sides by 2

$\frac{54}{2} =\frac{2}{2} (1+\sqrt{2})a^{2}$

$27 = (1+\sqrt{2})a^{2}$

Plugin √2 as 1.41

$27 = (1+1.41)a^{2}$

$27 = (2.41)a^{2}$

Divide both sides by 2.41

$\frac{27}{2.41} = \frac{2.41}{2.41} a^{2}$

$11.20 = a^{2}$

Taking square root on both sides

$\sqrt{11.20} = \sqrt{a^{2}}$

a = 3.346

a = 3.3 cm (rounded to nearest tenth)

so, length of side AB = 3.3 cm

Biologists have found that the number of chirps some crickets make per minute is related to temperature. The relationship is ver

pychu [463]

Answer:

points (x, y) = {(124, 68), (172, 80)}

y = 1/4x +37

Step-by-step explanation:

For the variable definitions given, the problem statement gives you the points ...

(chirps, temperature) = (x, y) = (124, 68) or (172, 80)

You are asked to find a linear equation that relates x and y.

The slope can be found using the slope formula:

m = (y2 -y1)/(x2 -x1)

m = (80 -68)/(172 -124) = 12/48 = 1/4

The y-intercept can be found from ...

b = y -mx

b = 68 -(1/4)(124) = 37

Then the equation that models the relationship can be written ...

y = 1/4x +37
