If it is geometric then
if the terms are a,b,c,d then
b/a=c/b=d/c
so
-54/-81=-36/-54=-24/-36?
2/3=2/3=2/3

and that is the common ratio

it is geomertic and common ratio is 2/3

A regular hexagon has sides of 2 feet. What is the area of the hexagon? 12 ft2 12 ft2 24 ft2 6 ft2
dimulka [17.4K]

For this case we have that by definition, the area of a regular hexagon is given by:

A = 6 (\frac {L ^ 2 * \sqrt {3}} {4})

Where:

L: It is hexagon side

According to the data of the statement we have:

L = 2 \ ft

Substituting:

A = 6 (\frac {2 ^ 2 * \sqrt {3}} {4})\\A = 6 (\frac {4 * \sqrt {3}} {4})\\A = 6 \sqrt {3}\\A = 10.4

Thus, the area of the hexagon is 10.4 \ ft ^ 2

Answer:

The area of the hexagon is10.4 \ ft ^ 2

Find two fractions with the difference of 1/5 but with neither denominator equal to 5? I know the answer from Google but how is
Bas_tet [7]
Suppose we try to write out this problem symbolically:

a     c      1
-- - --- = --- , b not equal to 5, d not equal to 5
b     d      5

Unfortunately, this equation contains 4 unknowns (too many)


We could do a bit of guesswork here:

a     c      1
-- - --- = --- , b not equal to 5, d not equal to 5
b     d      5

  8     6        2
--- - ----- = -----
10    10      10

This is true, but not all that wonderful, because all 3 fractions could be reduced and would then have denominator 5.

Find the reference angle for -3π/4
kykrilka [37]

Answer:

  π/4

Step-by-step explanation:

The reference angle will be the minimum of the absolute value of the angle, and the difference of that absolute value and pi.

  ref angle = min(|-3π/4|, π -|-3π/4|) = min(3π/4, π/4)

  ref angle = π/4

Given the function h(x) = 4x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3.
morpeh [17]
Section A) The AROC for Part A is 4.
            h(x) = 4 * 1. 4 is your answer.
Section B) The AROC for Part B is 1.
            h(x) = 4 * 1. 4 is your answer.

Part A: (Above)

Part B: There is no greater average change, both X's AROC is 4.


A.R.O.C: (Average Rate of Change)

I think this is right. Not 100% though
