Given the sequence 8, 16, 32, 64, ..., which expression would give the thirteenth term?
mrs_skeptik [129]
8, 16, 32, 64,…
 ×2  ×2  ×2

a_{n} = a_{1} * r^{n - 1}
a_{n} = 8 * 2^{13 - 1}
a_{n} = 8 * 2^{12}
a_{n} = 8 * 4096
a_{n} = 32768

           First Term: 8
      Second Term: 16
          Third Term: 32
        Fourth Term: 64
           Fifth Term: 128
          Sixth Term: 256
     Seventh Term: 512
       Eighth Term: 1024
         Ninth Term: 2048
        Tenth Term: 4096
   Eleventh Term: 8192
     Twelfth Term: 16384
Thirteenth Term: 32768

The\ expression\ that\ would\ give\ the\ thirteenth\ term\ of\ the\ problem\ would\ be\ the\ equation\ of\ the\ geometric\ sequence,\ which\ is\ equal\ to\ a_{n} = a_{1} * r^{n - 1}.

Jerome found another feather that made the difference between the longest and shortest feather 1 3/4 inches what could be the le
Alchen [17]

Answer:

By assuming that shortest feather has a length of 1/4 inches, the length of the longest feather is 2 inches.

Step-by-step explanation:

A mathematical translation of the statement of the problem is:

x - y = \frac{7}{4}

Where x, y represent the lengths of the longest and shortest feathers, respectively. Let assume that length of the shortest feather is 1/4 inches. Then, the length of the longest feather is:

x = y + \frac{7}{4}

x = 2

By assuming that shortest feather has a length of 1/4 inches, the length of the longest feather is 2 inches.

the function below represents the number of zombies, N, where t is the number of years since the zombies gained control of earth
raketka [301]
There is missing information about this question that I found online.
Given function is:
N(t) = 300\cdot 2^{-\frac{t}{8}}
The question is:
<span>Is this exponential growth or decay? Explain using your understanding of the properties of exponents.
</span>This is an exponential decay. 
In general, we can write down exponential functions like this:
f(x)=b^{ax}
Parameter a is the key parameter that will tell how exponential function behaves. If it is positive we have an exponential growth. If it is negative we can rewrite function like this:
f(x)=b^{-ax}=\frac{1}{b^{ax}}
We can notice that in this case, the denominator will exhibit exponential growth, in other words, the functions rapidly declines. This is an exponential decay.

5/7 = y/6<br> Solve the following proportion for y<br> Round your answer to the nearest tenth
RUDIKE [14]

Answer:

The value of y = 4.3

Step-by-step explanation:

It is given that,

5/7 = y/6

<u>To find the value of y</u>

We have, 5/7 = y/6

(5 * 6) = (y * 7)

y * 7 = 5 * 6

y = (5 * 6)/7

 = 30/7

 = 4.29

 ≈ 4.3

Therefore the correct answer, the value of y = 4.3
