To find the answer you simply find the square root of -169 which is 13 so x=13
The probability would be B because it is 8 cubed.
In the step after -6x+10=4x+20, he moved the terms incorrectly. you have to add 6x to both sides so it would be 10=4x+6x+20 which simplifies to 10=10x+20. subtract 20 from both sides to get -10=10x. divide both sides by 10. the answer is x=-1
Answer:
sin -115° = -0.91
Step-by-step explanation:
Point A is (cos 115°, sin 115°). Since cos 115° = -0.42 and sin 115° ≈ 0.91, it means that the coordinates at point A is (-0.42, 0.91).
As for point B which was revolved around -115°,
the coordinates will be similar to point A but you just have to change the negative.
B(cos -115°, sin -115°) = B(0.42, -0.91)
Answer:
$27.87
Step-by-step explanation:
if it is 1 by 2 you would multiply 1 x 2 and get 2 then multiply 13.87 x 2 to get 27.87 and it leaves you with $27.87
