Answer:
c. sin 30 is positive and sin -30 is negative
Step-by-step explanation:
Picture the unit circle (which is attached). <u>Sine is like the y-coordinate.</u> And -30 and 30 on the unit circle both form equally-sized triangles, but -30 is underneath the x-axis, so it has a <u>negative y-coordinate.</u> 30 is above the x-axis, so it has a <u>positive y-coordinate.</u>

D) neither the relation (length, volume) nor the relation (volume, length) is a function.
<u><em>Explanation: </em></u>
A function is a relation in which each element of the domain is mapped to no more than <u>1 element</u> of the range.
For (length, volume), the domain would be length and the range would be volume.
There could possibly be a length value that is mapped to more than one volume value, depending on the height of the pool. This means that (length, volume) is not always a function.
For (volume, length), volume is the domain and length is the range.
There could possibly be a volume that is mapped to more than one length, depending on the height of the pool. This means that (volume, length) is not always a function either.</span>

Answer:
560
Step-by-step explanation:
you listed the first 3, so it's 53 - 3 = 50 and you multiply 50 and 11 (the sequence is +11) to get 550. Add 10 and you get 560!
