Answer:
refer to the picture attached for steps
From this equation C°=[F°-32]÷1.8
F°=158×1.8 +32=316.4°
Answer:
Step-by-step explanation:
I'm not exatcly sure what is meant by magnitude but if it is the slope it is simply -7 if it is asking about the actual magnitude or length of the vector then we use pthagorean theorum which is:

when adjusted to solve for the answer is

which is c = sqrt (1^2) + (-7)^2 =
would be the exact answer
