Step-by-step explanation:
If the triangle is right then the square of the longest side (hypotenuse) will equal the sum of the squares of the other 2 sides.
longest side is x² + 1, then
(x² + 1)² = 
+ 2x² + 1
The sum of the square of the other 2 sides
(x² - 1)² + (2x)²
= - 2x² + 1 + 4x² = + 2x² + 1
Hence triangle is right
The best way to think about this value is to picture the graph of the "normal" sin wave. One period starts at (0, 0), goes up to a y value of 1 at an x value of
, goes back down to a y value of 0 at x =
, goes down to a y value of -1 at x =
and ends up completing one period at a y value of 0 and an x value of
. We can see from that what the sin ratios are at each one of those x values. When x = 0, y = 0, so the sin of 0 is 0. Check your calculator to see that this is true, but understanding the graph tells you WHY it is true.
2/3n = 8
divide 2/3 on both sides
n = 11.9999999 (11.99)
So the answer is n=11.99
From the given graph, we can say that the equation of the graph is
which can also be written as
Comparing it with slope intercept form, that is
we will get slope equals to 0 .
So the correct option is the third option .
