I was stuck on the same thing in my class test. I ended up failing but if I get the answers to it I’ll totally send them to you!!!
To me, it looks like you got everything right, but one serving of grapefruit has 41 mg more vitamin c per serving than the tomato juice.
here’s my work.
Tomato: 247.5 / 5.5 = 45
Grapefruit: 258 / 3 = 86
86 - 45 = 41.
Answer:
Period of the function is 4π
Step-by-step explanation:
Given is a graph:
It oscillates between -1 and +1
The graph shows angles on x axis and trig values on y axis.
The graph has value +1 when x=0 and reaches minimum -1 when x =2pi and again reaches y=1 when x =4 π
Thus we find that this is a periodic function with amplitude 1 and phase shift 0 and period 4π
So we get the period of the trignometric funciton is 4π
So option 1 is right
Verify:
Given function is y = cos
Since parent function y =cosx has a period of 2pi, we have
here period = 2pi/coefficient of x in cos
=2pi/(1/2)
=4pi
Answer:
C) They are parallel, but not opposites
Step-by-step explanation:
They would be opposites if they had the same magnitude. As is, they are simply parallel with opposite directions.
