<u>Answer</u>
-3/√13
<u>Explanation</u>
We are going to take angle ∅ to be at the origin (point (0,0)).
The point at (-2, -3) means, 2 units to the left (negative side of x-axis) and 3 units downwards (negative side of y-xis).
This will make a right triangle with a hypotenuse of √(2²+3²) = √13
The angle ∅ is in the 3rd quadrant where cosine is negative.
cosine = adjacent/hypotenuse
The exact answer for cos ∅ = -2/√13
Answer:
-1
Step-by-step explanation:
Using the slope-intercept form equation, you know that y=mx+b.
m is the slope of the line and b is the y intercept. The y intercept is where the point is when x=0. If you look at your equation and replace x with 0, you'll see that the y intercept (b) is 9.
You're looking for the slope of Line Q which is m in the equation. In this equation the slope is - 1.
Since Line R is supposed to be parallel to Line Q, then they must have the same slope. So both lines have a slope of - 1.

Find h, when BSA = 1.5 and w = 50
We have:
Substitute 1.5 for BSA and 50 for w
Multiply both sides by 60
Square both sides
Divide both sides by 50
<em>Hence, the patient's height is 162.0cm</em>
