Step-by-step explanation:
y/2=2/5
5y=4
y=4/5
so, y=4/5
Basically it's just asking you to draw a picture with an explanation of what you drew or why you drew it.
Hope that this helped. (;
Cos
θ
=
√
5
3
or it could be cos
θ
=
√
5
−
3
Explanation:
Since sin
θ
is negative, it can be in the third or fourth quadrant
Drawing your right-angled triangle, place your
θ
in one of three corners. Your longest side will be 3 and the side opposite the
θ
will be -2. Finally, using Pythagoras theorem, your last side should be
√
5
Now, if your triangle was in the third quadrant, you would have
cos
θ
=
√
5
−
3
since cosine is negative in the third quadrant
But if your triangle was in the fourth quadrant, you would have
cos
θ
=
√
5
3
since cosine is positive in the fourth quadrant
Answer:
87.92 square inches
Step-by-step explanation:
Surface area for cylinder is given by 
where r is the radius and h is the height of cylinder.
Given that candle is cylindrical in shape
Thus, Surface area for candle is calculated as given below\\

Thus, total surface area for candle is 87.92 square inches.
Experiental probability is the correct choice because you will have actual data from an experiment that you are using to create the ratio of outcomes to attempts. This is the scientific and mathematical name for a tested ratio. Theoretical probability, on the other hand, is what you would expect to happen if you were to perform the test.
