Hi
6*3 + (9-3)
= 18 + 3
= 21
I hope that's help !
Explanation is given step by step just below:
tan(theta(t))=y(t)/x(t)
differentiate
sec^2(theta(t))*theta'(t)=y'(t)x(t)-y(t)x'(t)/x^2(t)
thus
theta'(t)=(y'(t)x(t)-y(t)x'(t))
divided by (x^2(t)*sec^2(θ(t))
1) What left

*Obs: remember that left at least 42 dollars. In other words, the left over is equal or more than 42 dollars.
2) At the beginning
Letter C
Answer:
x = 50
