Answers

Answer:

s = -43.245

Step-by-step explanation:

First, you move the constant to the right:

-s=44-0.755

Calculate:

-s=43.245

Then, you change the signs:

s=-43.245

To explain your reasoning, you can say that:

To add any complex numbers together, you add the constants to each other and the numbers together.

John has taken out a loan for college. He started paying off the loan with a first payment of $100. Each month he pays, he wants to pay back 1.1 times as the amount he paid the month betore. Explain to Jo howto represent his first 20 payment n sigma notation.Then esplain how to tind the sum of his frst 20 pyments, using complete sentences. Esplain why this series is convergent or divergent

Answers

Since each term of the series is 1.1 times the previous one, the series is geometric. The generic term of a geometric series is
  a_(n)=a_(0)\cdot r^((n-1))

The sum in sigma notation simply adds these terms. The leading factor of 100 can be factored out.
sum=\displayform{100\cdot\sum\limits_(n=1)^(20){1.1^((n-1))}}

The sum can be found by adding the terms or by using the formula for the sum of a geometric series. In the latter case, we have
sum=100\cdot(1.1^(20)-1)/(1.1-1)\approx5727.50

The series is divergent because the common ratio of terms is greater than 1. (Of course, any finite number of terms will have a finite sum.)

4 scarfs 86.4 inch long. Total length of all scarfs put together in feet

Answers

Answer: 28.8ft

Step-by-step explanation:

Start by multiplying 86.4 by 4. You should get 345.6. Since there are 12 inches in a foot, divide 345.6 by 12. You should get your final answer as 28.8ft.

Find the 12th term in the sequence: 1/16, -1/8, 1/4

Answers

Answer:

Step-by-step explanation:

hello :

the sequence is geometric because : (1/4)/(-1/8) = (-1/8)/(1/16)=-2   = r

the nth term is :  An =A1 × r^(n-1)

a common ratio is : r  and A1 the first term

in this exercice :   r =2         A1 = 1/16

when : n =12 you have the  12rd term  A12

A12 = 1/16 × 2^(12-1)  = 1/16 × 2^(11)
