Find the missing term in the geometric sequence : 8 , 20 , 50, 125 , ____

Mathematics
1 answer:
Solnce55 [7]3 years ago
3 0

Answer:

312.50

Step-by-step explanation:

8 , 20 , 50, 125 , 312.50

First term, a = 8

Second term, ar = 20

Find common ratio, r

Substitute a = 8 into second equation

ar = 20

8r = 20

r = 20/8

r = 2.5

Find the fifth term

ar⁴

= 8 * 2.5⁴

= 8 * 39.0625

= 312.50

Fifth term, ar⁴ = 312.50

<h3>Check if the Sum of the Digits are</h3><h2>Divisible By 3.</h2><h3>Let's check, then.</h3>

5,504.

5 + 5 + 4 = 14.

14 is not divisible by three, therefore,

What is the least common denominator of 9,8,6,5
Alex

Answer:

1

Step-by-step explanation:

LCD = 1

Equivalent Fractions with the LCD

9 = 9/1

8 = 8/1

6 = 6/1

5 = 5/1

Solution:

Rewriting input as fractions if necessary:

9/1, 8/1, 6/1, 5/1

For the denominators (1, 1, 1, 1) the least common multiple (LCM) is 1.

LCM(1, 1, 1, 1)

Therefore, the least common denominator (LCD) is 1.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

9 = 9/1 × 1/1 = 9/1

8 = 8/1 × 1/1 = 8/1

6 = 6/1 × 1/1 = 6/1

5 = 5/1 × 1/1 = 5/1

What are the dimensions of the matrix?
DerKrebs [107]

Answer:

  • The dimensions of a matrix are the number of rows × the number of columns of the matrix.
  • For the example below, the the matrix is 3 × 4.

Explanation:

<em>The dimensions of a matrix</em> is the number of rows × the number of columns of the matrix.

Your matrix is garbled. Thus, to help you I will work with an hypothetical matrix.

Assume the matrix:

        \left[\begin{array}{cccc}1&0&0&0\\2&4&0&3\\0&0&0&9\end{array}\right]

That matrix has four colums and 3 rows.

For instance, the first colum is:

            \left[\begin{array}{c}1\\2\\0\end{array}\right]        Thus, it has 4 columns.

And the second row is:

          \left[\begin{array}{cccc}2&4&0&3\end{array}\right]         Thus, it has 3 rows.

Hence,  the matrix is 3 × 4.

The first number is the number of rows and the second number is the number of columnns.
