Answer:
The ball is 3.86 meters from the wall when it stops rolling.
Step-by-step explanation:
Representation of the situation:
This situation can be represented by a right triangle:
The hypotenuse is the distance the ball traveled, of 6 meters.
The distance from the wall is the side opposite to the angle of 40º.
We have that:
Sine of an angle is the length of the opposite side divided by the hypotenuse. So, in this situation.
Sine of 40 degrees = Distance from the wall/6
Sine of 40 degrees is of 0.64278760968.
Distance = 6*0.64278760968 = 3.86.
The ball is 3.86 meters from the wall when it stops rolling.
Answer:
45x and 90
Step-by-step explanation:
Answer:
y=2
Step-by-step explanation:
-(3y+2) -(-2y-4)=0
Distribute the minus signs
-3y -2 +2y +4 = 0
Combine like terms
-y +2 = 0
Add y to each side
-y+y +2 = 0+y
2=y
Check
-(3*2+2) -( -2*2-4) =0
-(6+2) -(-4-4)=0
-8 - (-8) =0
-8+8 =0
0=0
I believe its 12?... Maybe not.
If so delete this answer.
