Step-by-step explanation:
You have found a function r(V(t)). We can see that this function is a one variable function. The variable is time.
So in this specific function we can call r(v(t)), r(t).
So:
If α is the moment that the radius is 10 inches and since the function above gives radius in inches we have to solve the equation:
Which is the same as:
Answer:
b) 158
Step-by-step explanation:
The two horizontal lines are called parallel lines so x is the same as the given angle and the ones diagonal from them would be the same as well.
