We need Vector ST which is just T - S
(7-3.4-2) = (4,2)
So now we need the perpindicular. The easiest way to do this, is to know that , in R2 that the perindicular is just the negatice inverse. So its (2,-4)

Answer:
k=0
Step-by-step explanation:
R(x)=kx-2x²
R(1/4)=k(1/4)-2(1/4)²=k/4-1/8
R(-1/4)=k(-1/4)-2(-1/4)²=-k/4-1/8
R(1/4)=R(-1/4)
k/4-1/8=-k/4-1/8
k/4+k/4=1/8-1/8
2k/4=0
2k=0
k=0
Answer:
-10.4
Step-by-step explanation:
You add all of the temperatures together and then divide the total by 4 (because there are four temperatures) and you get 10.35. You round that up to 10.4
