Line p had a slope of 5/4. line q is perpendicular to line p. what is the slope of line q?

1 answer:

6 0

Answer: -4/5

Step-by-step explanation: It's important to understand

that perpendicular lines have negative reciprocal slopes.

"Negative reciprocal" is just a fancy way

of saying flip the fraction and change the sign.

So if we flip the fraction 5/4 we get 4/5 and

if we change the sign we get -4/5.

Since beta is in the first quadrant, the final answer will be positive.

To find cos(beta) so we can use the half angle identity, we can substitute into the Pythagorean identity. Doing so gives us that

$\sin( \beta ) = \frac{ \sqrt{17} }{5}$

So, this means that

$\sin( \frac{ \beta }{2} ) = \sqrt{ \frac{1 - \frac{ \sqrt{17} }{2} }{2} } = \sqrt{ \frac{2 - \sqrt{17} }{4} } = \frac{ \sqrt{2 - \sqrt{17} } }{2}$

Number 3 would be y=4x.
Number 5 would be 9 1/24 for the left side and 133/8 for the right side.
