Answer: 47°C
Step-by-step explanation:
Since we are given the velocity, all we have to do is plug in 358 for v and solve for t.
[divide both sides by 20]
[square both sides to cancel out square root]
[subtract both sides by 273]
Now that we know the temperature is 47.41°C, we know our answer choice is D.
Answer:
( cos40° + isin40°)
Step-by-step explanation:
To divide
= [ cos(x₁ - x₂) + isin(x₁ - x₂)
Given
= ( cos(90 - 50)° + isin(90 - 50)°
= ( cos40° + isin40° )
