Answer:
79 °F
Step-by-step explanation:
Newton’s Law of Cooling:

Data
- The initial temperature of a liquid is 160 °F
- The temperature in the room (c) is 76 °F
- Then a = 160 - 76 = 84 °F
Replacing into the equation:

y = 79 °F
Answer:
Step-by-step explanation:
Cos θ =<u> u*v </u>
IuI *IvI
u * v = 7*(-1) + (-2)*2
= -7 - 4
= -11
IuI = 
= 
= 
I vI = 
= 
= 
Cos θ = 
= 
Cos θ = -0.68
θ = 132.5°
