Answer:

The answers are...:

The common ratio is -3

the sequence of the function is 2,-6, 18, -54, 162

and

the sequence of the function model is geometric

I hope this helps ^^"

Step-by-step explanation:

the common ratio is just from the -3 itself

the sequence model is just plugging n for every term so

a(1) would equal to 2, a(2)=-6 , a(3) would equal to -18, etc

and the geometric is bc it has the exponential that has (n-1), thus it is a geometric sequence

Solve for the Simplest form
tino4ka555 [31]
How to solve:

\frac{5}{6} - \frac{3}{8}

Write all numerators above the least common denominator which is 24 in this case.
\frac{20-9}{24}

Subtract the numbers
\frac{11}{24}

Alternate form: 0.458333

The final, simplified, fraction answer is: \frac{11}{24}

I need help solving this pls
Oksana_A [137]

Answer:

Adding them together. x = 3/2, y = 8

Step-by-step explanation:

Adding because we want to get rid of a variable. If we add, 2x + 6x = 8x, 1/2 * y + (-1/2 * y) = 0, and 7 + 5 = 12. Adding gets rid of the y variable.

By adding we get that 8x = 12 which gives us x = 12/8 = 3/2

Substituting this back into either equation will give us y = 8.

Is anybody able to help me get number ten? (Geometry)
Nikitich [7]

Answer:

Aha..our nemesis problem. :)

The area is 129.90 ft ^2.

Step-by-step explanation:

First, use a 30-60-90 triagle to find the apothem.

5\sqrt{3} =8.66\\8.66*5=43.30\\43.30/2=21.65\\

That is the area of 1 triangle. There are 6 of them in a hexagon, so multiply that number by 6:

21.65*6=129.90 ft ^2

Have a great day!
