Answer:
B. 70
Step-by-step explanation:
We have the sum given by 
Now, we open the summation by substituting the values of 'i',
i.e. = (1+11) + (2+11) + (3+11) +(4+11) +(5+11)
i.e. = 12 + 13 + 14 + 15 + 16
i.e. = 70.
Hence, the sum of is 70.
So, option B is correct.
is equivalent to <span>
That is in the form </span><span>
which is point slope form
In this case,
m = 1/2 is the slope
(x1,y1) = (7,-8) is the point the line goes through</span>
Answer:
y= 3
Step-by-step explanation:
The triangle on the left is a right triangle, so we can use trig functions to solve for the missing side, y.
First, find the length of the side that both triangles are connected to.
tan30=x/9
Isolate the x variable and solve.
9(tan30)=x
x= 5.19615
Now use the Pythagorean Theorem to solve for the side length, y.
a^2+ b^2 = c^2
(5.19615)^2+ b^2= 6^2
c= 3
