Answer:
B, slope and rate of change
Step-by-step explanation:
Slope and rate of change mean the same thing, as they both mean how a graph will increase/decrease as the change in y over change in x (rise over run)
This relation is a function because each input has only one output
15%=15/100=0.15
'of' means multiply
15% of 32.50=
0.15 times 32.50=4.875
Use the order of operations or PEMDAS
I think it is possible. Like, if the angles are smaller than 90 degrees. I'm not really sure.
