Step-by-step explanation:
Those lines will never touch.
Original price - discount = sales price
x - 0.3(x) = 63
0.7x = 63
x = 63/0.7
x = 90 <=== original price
Answer:
δx=0.035 m
Step-by-step explanation:
We use the expression of the uncertainty of x:
δx = (x/(vo cosθ))*sqrt((cosθ)² (δV₀)²+(V₀ sinθ)²(δθ)² )
First of all, we need to identify δV₀ and δθ. In our case δV₀ = 0.002 m/s and δθ = 0.0175 rad.
Remember: 1° = 0.0175 rad. This is very important to get the right answer here.
Now, we just need to replace the values we have into the equation δx:
δx = (0.5/(3.49*cos(76)))*sqrt((cos(76))²*(0.02)²+(3.49*sin(76))²*(0.0175)²)
δx = 0.035 m.
Have a nice day!
