First plug in the numbers 5 x 8 = 40
40-4y+6x8=48
40-4y+48
Answer:
y=-2x-2
Step-by-step explanation:
Recall that
sin²(<em>x</em>) = (1 - cos(2<em>x</em>))/2
so that
sin²(7<em>π</em>/8) = (1 - cos(7<em>π</em>/4))/2
sin²(5<em>π</em>/8) = (1 - cos(5<em>π</em>/4))/2
Then
sin²(7<em>π</em>/8) + sin²(5<em>π</em>/8) = (1 - cos(7<em>π</em>/4) + 1 - cos(5<em>π</em>/4))/2
… = 1 - 1/2 (cos(7<em>π</em>/4) + cos(5<em>π</em>/4))
… = 1 - 1/2 (1/√2 - 1/√2)
… = 1
I think the answer is ur dad
Answer:
<u>Piece-Wise Function</u>
- can have more than one type of function
- holes can exist
- to evaluate, look at the right side to determine which piece of the function to use
<u>Linear Function</u>
- is written in standard form Ax + By = C
- slope is the same for the entire graph
- is written in slope-intercept form y=mx+b
Neither one of these always looks like a parabola.
