"+-" should always be changed to "-".

You have 3 - 7 - 2.  You may evaluate this from left to right, obtaining -4 -2, or -6.

4 - 16 -2(2) involves multiplication, which must be carried out before addition or subtraction.  Thus, 4 - 16 - 4.  Working from left to right, we get -12 - 4 = -16

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 dy/dx from<br>y=3×^2+5×^4 -10<br>​
Valentin [98]
I’m rewriting it into d/dx so it’s a bit faster for me
d/dx(3x^2+5x^4-10)
=d/dx(3x^2)+d/dx(5x^4)+d/dx(-10)
=6x+20x^3, which is your desired answer
