The square root of 64 is 8 but put 8 to the 1/2 power
The answer is 4
Answer: sin u = -5/13 and cos v = -15/17
Step-by-step explanation:
The nice thing about trig, a little information goes a long way. That’s because there is a lot of geometry and structure in the subject. If I have sin u = opp/hyp, then I know opp is the opposite side from u, and the hypotenuse is hyp, and the adjacent side must fit the Pythagorean equation opp^2 + adj^2 = hyp^2.
So for u: (-5)^2 + adj^2 = 13^2, so with what you gave us (Quad 3),
==> adj of u = -12 therefore cos u = -12/13
Same argument for v: adj = -15,
opp^2 + (-15)^2 = 17^2 ==> opp = -8 therefore sin v = -8/17
The cosine rule for cos (u + v) = (cos u)(cos v) - (sin u)(sin v) and now we substitute: cos (u + v) = (-12/13)(-15/17) - (-5/13)(-8/17)
I am too lazy to do the remaining arithmetic, but I think we have created a way to approach all of the similar problems.
The statement that: pairs of corresponding points lie on parallel lines in a reflection, is false.
<h3>What are reflections?</h3>
When a point is reflected, then the point is flipped across a point or line of reflection
When a point is reflected, the following highlights are possible
- The corresponding points can line on the same line
- The corresponding points can line on parallel lines
Using the above highlights, we can conclude that the statement is false.
This is so because, corresponding points are not always on parallel lines

Answer:
J 672 cubic inches
Step-by-step explanation:
The volume of a rectangular prism is
V = l*w*h
V = 14 inches * 8 inches * 6 inches
V =672 inches^3
Answer:
The answer is option C
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the line first find the slope
The line has a y intercept of 2 which is
(0 , 2)
Slope of the line using points
( 1 ,1) and (0,2) is
So the equation of the line using point (1,1) is
y - 1 = - 1(x - 1)
y - 1 = - x + 1
x + y - 1 - 1 = 0
We have the final answer as
<h3>x + y - 2 = 0</h3>
Hope this helps you
