Answer:
I think it's A, y = 1/2 cos(x + π/4)
<h3>
Answer: f(x) = (-1/2)x+1, choice B</h3>
=================================================
Explanation:
The diagonal line passes through 1 on the vertical y axis. So the y intercept is b = 1. This means the location of the y intercept is (0,1).
Start at (0,1) and move down 1 and to the right 2 to arrive at (2,0). This is another point on the diagonal line. The motion of "down 1 and right 2" is effectively the slope
slope = rise/run = -1/2
rise = -1, run = 2
The rise being negative means we have gone downhill as we move to the right.
With m = -1/2 as the slope and b = 1 as the y intercept, we go from y = mx+b to y = (-1/2)x+1
The last thing to do is replace y with f(x) to get f(x) = (-1/2)x+1 as the final answer.
0.9 should be correct
hope this helps:)
Answer:
1273.4
Step-by-step explanation:
1273.39
thousands, hundreds, tens, ones . tenths hundredths
We are rounding the 3 so we look at the 9
9 is greater than or equal to 5 so we will round the 3 up
1273.4
