Given any integers a,b, and c, if a−b is even and b−c is even, what can you say about the parity of 2a − (b + c)? Prove your answer
Use the quotient rule to find the derivative of the following. $y = \frac{9x^2 + 4}{x^2 + 6}$ $\frac{dy}{dx} = \square$
Problem 4: (20 pts) Transform this Moore machine into a Mealy machine.
A new drug product is found to be ineffective after it has decomposed 10% (to shelf-life). The original concentration of one sample was 35.0 mg/mL. When assayed 30 months later, the concentration was found to be 20.5 mg/mL. i)Assuming that the decomposition is first-order, what should be the expiration time on the label?(10 marks)ii) What is the half-life of this product?

8. Relative velocity. In this problem, we'll have the following definitions: B = boat G = ground W = water A river is flowing at 1.5 m/s in the +x direction, as shown. The boat is pointed directly across the stream (perpendicular to the banks). The boat's speed in still water is 2.5 m/s. Summary: $\vec{v}_{WG}$ = 1.5 m/s $\hat{i}$ (velocity of water with respect to ground) $\vec{v}_{BW}$ = 2.5 m/s (velocity of boat with respect to water) $\vec{v}_{BG}$ = ? Find the magnitude and direction of the velocity of the boat with respect to the ground. Make the direction clear by putting it in a diagram. (Viewfromabove) $\vec{v}_{WG}$=1.5 m/s Bank $\vec{v}_{BW}$=2.5 m/s Bank $\hat{y}$ $\rightarrow +x$
