<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>
Your answer would be 2.6 meters per second
390 ÷ 150 = 2.6
Answer:
The width would be 10 inches.
Step-by-step explanation:
To find this, start by labeling the width of the rectangle as x. Now we can express the length as 3x - 5. Now use the perimeter formula and the known perimeter to find x (which is the width).
2l + 2w = P
2(3x - 5) + 2x = 70
6x - 10 + 2x = 70
8x - 10 = 70
8x - 80
x = 10
first solve the one in the bracket
4+6 = 10
now 2×10 = 20
the expression becomes
but
Answer:
1) The numbers 0 and 1 are neither prime nor composite because they represent nothingness (zero) and wholeness (one). Only whole numbers larger than 1 can be classified as prime or composite.
