What is the sum of the first 47 terms of the sequence?
-215,-201,-187,-173,...

Answers

Answer 1

Answer:

5029

Step-by-step explanation:

There is a common difference between consecutive terms, that is

d = - 201 - (- 215) = - 187 - (- 201) = - 173 - (- 187) = 14

This indicates the sequence is arithmetic with sum to n term

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Here a₁ = - 215 and d = 14 , then

[tex]S_{47}[/tex] = [tex]\frac{47}{2}[/tex] [ (2 × - 215) + (46 × 14) ]

     = 23.5 (- 430 + 644)

    = 23.5 × 214

    = 5029

How to subtract two complex number?

For the subtraction of two complex numbers we subtract real part from the real and imaginary from imaginary.

According to the given question.

We have two complex numbers

t = 4 + 0i and u = 6 + 2i

Therefore,

[tex]t - u = 4+ 0i - ( 6 + 2i)[/tex]

⇒[tex]t - u = 4 + 0i - 6 - 2i[/tex]

⇒[tex]t - u = -2 -2i[/tex]

⇒[tex]t - u = -2(1+i)[/tex]

Hence, t - u = -2(1 + i).

Can someone explain how to do this? I keep getting it wrong

Answers

Answer:

Step-by-step explanation:

in order to find the measurements of all the angles you must find x and to find x you have to realize that the total sum of a triangle inner angles is 180 so you add all those together (48+x+x-44=180) and then if you solve that it gives you 2x+4=180 and then simplify 2x=176 and then x=88

then you plug x into the angles in order to find out the actual measurements

so a is obviously 48 but then b is equal to x which isequal to 88

and then for c it will be x-44 so its 88-44 which equals 44 and that is your answer

if you want to double check take all of your answers and see if they add up to 180

Use inequalities symbols to order the numbers -7,7, 1 and -1 from least to greatest.

please hurry i need to pass this class

who ever answers this i will give u 100 points

Answers

If we are ordering these from least to greatest, it would be as follows:

-7, -1, 1, 7

Remember that the 'smaller' negative numbers are those that are further away from 0.

Then, if we need to add inequality signs, it would be as follows:

-7 < -1 < 1 < 7

Basically, we are saying that -7 is less than -1, which is less than 1, which is less than 7.
