Answer: 18
Step-by-step explanation:
2(9)=18
The inverse function is f^-1 (x)= -2+(x/3) dont add the parenethese though, i used the parenethese to show that its x over 3. hope that helped! :D
18/90 in simplest form is 1/5
18 and 90 are both divisible by 9
18 = 2
90 = 10
2 and 10 are divisible by 2
2 = 1
10 = 5
18/90 = 1/5
<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

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.
