Answer:
Step-by-step explanation:
Given that,
...(1)
We need to find the value of .
Put n = 1 to find the first term.
Put n = 2 to find the second term.
Put n = 3 to find the third term.
Put n = 10 to find the tenth term.
It means we need to find the sum of 5,7,9,.....,23.
The formula for the sum of n terms is given by :
We have, n = 10, a = 5 and
So,
So, the value of is equal to 280.
The y intercept of a graph containing the two points (3,1) and (7,-2) is
<em><u>Solution:</u></em>
Given points are (3, 1) and (7, -2)
<em><u>The equation of line in slope intercept form is given as:</u></em>
y = mx + c ------- eqn 1
Where, "m" is the slope of line and "c" is the y intercept
<em><u>Let us first find the slope of line</u></em>
The slope of line is given as:
Here the points are (3, 1) and (7, -2)
Substituting in formula, we get
To find the y intercept:
Thus y -intercept is
