We have that
<span>f(x)=2x</span>²<span>+12x+16
using a graph tool
see the attached figure</span>
With wat?
Yes
Step by step explanation
Answer: In the exact order up to down: 80, 74, 110, 96, 80
Step-by-step explanation:
Do the equation
360=(x-6)+(x+30)+1.2x+x
we can simplify by doing
360=(x-6)+(x+30)+2.2x
=360=x-6+x+30+2.2x
=360=4.2x+24
=336=4.2x
=80=x
x=80

<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
