Find the 11th partial sum of the summation of negative 7i plus 22, from i equals 1 to infinity.
Alinara [238K]
The answer is -220 
What you do is take -7 and multiply that by (1+2+3+4+5+6+7+8+9+10+11) and then after that add 11 again and multiply it by 22. It would look like this. 

-7 x (1+2+3+4+5+6+7+8+9+10+11) +11 x 22

Simplify that to -7 x 66 +11 x 22

now multiply -7 and 66 to get -462 

-462 +11 x 22 

multiply 11 and 22 

-462 + 242 

and your final answer will be -220

A self own company charges $40 per month +0.05 cents for each text message sent.Select expression is there a percent of cost in
kondaur [170]
<h3>The monthly cost of cell phone is A  =  40 + 0.005 m</h3>

Step-by-step explanation:

The monthly fixed charges by mobile company = $40

The cost of sending each text message  = 0.05 cents

Now, 100 cents  = 1 dollar

⇒ 1 cent  =$ (\frac{1}{100} )

⇒ 0.05  cent s =$ (\frac{1}{100}  \times 0.05)  =0.0005

Also, the number of text messages send  =  m

So, the cost of sending m text message  = m x ( cost of 1 text )

= m x ( $ 0.0005) = 0.0005 m

Now, Total bill = Fixed rate + cost of m texts

⇒ A  =$40  +  $ 0.0005 m

Hence, the monthly cost of cell phone is A  =  40 + 0.005 m
