Answer:

$\frac{1}{2}$

Step-by-step explanation:

sin45° = $\frac{1}{\sqrt{2} }$ ← exact value , then

sin²45° = $\frac{1}{\sqrt{2} }$ × $\frac{1}{\sqrt{2} }$ = $\frac{1}{2}$

Construct a linear function, f(x), to model the ordered pairs (6, 2) and (7, −5). f(x) = 7x + 44 f(x) = x + 4 f(x) = −44x + 7 f(

First we find the slope between the two given points.

m = (y2 - y1)/(x2 - x1) = (-5 - 2)/(7 - 6) = -7/1 = -7

Now we use the slope-intercept equation of a line.

y = mx + b

We use one point as x and y, and we solve for b.

2 = -7(6) + b

2 = -42 + b

b = 44

The equation is

y = -7x + 44

Answer: f(x) = -7x + 44

Line r has a slope of -5/2 line s has a slope of 2/5 are line r and line parallel or perpendicular

Elis [28]

Vocab:
Parallel = same slope
Perpendicular = opposite sign and reciprocal slope

-5/2 opposite and reciprocal = 2/5

Solution: they are perpendicular
