Select the correct answer. what is this series written in sigma notation? 2.5 2.5(1.2) 2.5(1.2)2 ⋯ 2.5(1.2)87 a. ∑ k = 1 87 2.5
Marat540 [252]

<u> ∑ k = 1 88 2.5 ⁢ ( 1.2 ) k</u><u>  is this series written in </u><u>sigma notation. </u>

What is the series written in sigma notation?

  • A series can be represented in a compact form, called summation or sigma notation.
  • The Greek capital letter, ∑ , is used to represent the sum. The series 4+8+12+16+20+24 can be expressed as 6∑n=14n .
  • The expression is read as the sum of 4n as n goes from 1 to 6 .

Given:

2.5 + 2.5(1.2) + 2.5(1.2)2 + ⋯ + 2.5(1.2)87

If we look at the power it is always one less the term i.e., for first term the value of k=0.

So, the series in the form of summation can be written as

∑ k = 1 88 2.5 ⁢ ( 1.2 ) k

Find the size of angel x<br><br><br>​
Juliette [100K]

Answer:

The measurement of x is 56 degrees.

Step-by-step explanation:

Below that angle is a straight line measuring 180 degrees, so if one part of that 180 is 124 you would take 124 from 180.

180-124=x

x=56

Hope this has helped have a great day.
