Answer:
5sin38
Step-by-step explanation:
Sin = opp/hyp
sin38 = BC/5
5sin38 = BC
If A=Aiden’s weight and J=Jacob’s weight, so A=J-39 or J=A+39.
J>100 so A+39>100, and A>61 pounds.
A+J>>61+100, A+J>>161. Or, A+J=2J-39=2A+39>161.
If A=62, J=101, so A+J=163 pounds.
Therefore we can say their combined weights will 161 pounds, and 163 pounds would be a typical weight.
Answer:
C: (1,3)
Step-by-step explanation:
If we count 1 to the right on the x-axis and count 3 up on the y-axis, we will end up at the point of intersection which is (1,3).
Answer: 
Step-by-step explanation:

Get two coordinates from the graph
(0,1) and (1,3)
Use them to find gradient
(3-1)/(1-0)=2
