Answer:
Correct answer: sin 2Θ = - 24/25
Step-by-step explanation:
If under the standard position you think that the first arm (side) belongs to the positive direction of the x axis and the second one passes through a given point then it is:
if we form a right triangle with sides 3 and 4 then the hypotenuse is 5.
sin Θ = 4/5 and cos Θ = - 3/5
we know that the formula for double the value of the angle is:
sin 2Θ = 2 sinΘ cosΘ = 2 · 4/5 · ( - 3/5) = - 24/25
sin 2Θ = - 24/25

Answer:
Option B, (-9, -5), 3
Step-by-step explanation:
<u>The point slope form in: y - y1 = m(x - x1)</u>
m is the slope
(x1, y1) is the point
<u>Step 1: Determine what the slope and point is their equation</u>
y + 5 = 3(x + 9)
3 is the slope
(-9, -5) is the point
Answer: Option B, (-9, -5), 3
Answer:
A
Step-by-step explanation:
Answer:
x = 11
y = 3
Step-by-step explanation:
4y+1=6y-5
-4y -4y
+1 =2y-5
+5 +5
6/2=2y/2
3=y
2x-4= 18
+4 +4
2x/2 = 22/2
x=11
