Answer:
Completing the square.
Step-by-step explanation:
ax2 + bx + c has "x" in it twice, which is hard to solve.
But there is a way to rearrange it so that "x" only appears once. It is called Completing the Square
Answer:
The sum of the first 47 terms of the given series = 6016
Step-by-step explanation:
Given the sequence
13, 18, 23, ...
An arithmetic sequence has a constant difference 'd' and is defined by
As the difference between all the adjacent terms is the same.
so
Arithmetic sequence sum formula
Put the values
Thus, the sum of the first 47 terms of the given series = 6016
the first part isn't 90, it's 180.
the whole circle is 360, half of 360 is 180
an acute angle is any angle less than 90 degrees.
