Answer:
Yes
Step-by-step explanation:
If you can draw a verticle line through any part and it only crosses the line once it is a function
1+4 = 5
2+5 and add 5 = 12
3+6 and add 12 = 21
4+7+21=32
5+8+32=45
6+9+45=60
7+10+60=77
8+11+77=96
X=56°
Because cos =90- sin
2,007.5
Explanation: The round trip to go to the park is 5.5 (2.75 times). Then multiply 5.5 by 365 days and you’ll get 2,007.5
3 / 15 = 1 / 5
5 / 20 = 1 / 4
so no, they are not. we know this because when you turn them into proportions and simplify them, the two rates are not equal
