<h3>The sum expressed in sigma notation is:</h3>
<u><em>Solution:</em></u>
Given that,
11 + 17 + 23 + 29 + 35 + 41
We have to express the sum in sigma notation
Analyse the series
5 + 6(1) = 11
5 + 6(2) = 17
5 + 6(3) = 5 + 18 = 23
5 + 6(4) = 5 + 24 = 29
5 + 6(5) = 5 + 30 = 35
5 + 6(6) = 5 + 36 = 41
<em><u>Thus the series goes on like this:</u></em>
5 + 6(n) , where n = 1 to 6
<em><u>This can be expressed in sigma notation as:</u></em>
<em><u>We can expand the sigma notation and verify the results</u></em>
Answer:
Step-by-step explanation:
Bus One
speed = x
t = 7 hours
d = ?
Bus two
speed = x + 11
time = 7 hours
d1 = 1015 miles - d
Equations
d = s * t
Bus 1 + bus 2 = 1015
Solution
x * 7 + (x + 11)*7 = 1015
7x + 7x + 11*7 = 1015
14x + 77 =1015
14x + 77 - 77 = 1015 - 77
14x = 938
14x/14 = 938/14
x = 67 miles / hour
x + 11 = 78 miles / hour
Answer:
<h2>
$13,400</h2>
Step-by-step explanation:
Step one:
let us first compute the tuition and books for the two years
we are told that the tuition is $5,500 per year
For the two years,the tuition will be 5,500*2= $11,000
Step two:
we need to calculate the cost of transportation for the two years also
in two years there are 24 months
if Lakita will spend $100 per months
then in 24 months Lakita will spend= 24*100= $2400
Hence her education cost her in total is
=$11,000+$2400
=$13,400
7<n<8 is the right answer
Answer:
