Draw resonance structures for the following compound: Step 1 First, add curved arrow(s) to show the resonance using the following pattern: a pi bond between two atoms of differing electronegativity. Modify the second structure given to draw the new resonance structure. Include relevant formal charges in your structure. Use the + and - tools to add/remove charges to an atom, and use the single bond tool to add/remove double bonds. Edit Drawing

Imagine Fish #1 (on the left) is making fish noises, hoping to be heard by Fish #2 (on the right). However, the water is flowing to the left rather quickly. Match the speed of the water with what Fish #2 hears. The water is flowing slower than the speed of sound in water. The water is not flowing at all. The water is flowing faster than the speed of sound in water.
What is the branch of statistics that refers to methods for summarizing the collected data
Question 1 A fan blade rotates with angular velocity given by ωz(t) = γ - βt². Constants Part A Calculate the angular acceleration as a function of time. Express your answer in terms of the variables β, γ, and t. az(t) = Submit Request Answer Part B If γ = 5.40 rad/s and β = 0.835 rad/s³, calculate the instantaneous angular acceleration αz at t = 2.90 s. Express your answer in radians per second squared. αz = rad/s²
Assume cars and motorcycles are substitute goods in consumption. If the cost of car production increases we would expect the equilibrium price of motorcycles to ______ and the equilibrium quantity ______.
The process of financial intermediation increases the economy's ability to produce, is always used when a borrower needs to obtain funds, creates a net cost to an economy, and is used primarily in underdeveloped countries.
W(x, y, z) = xy + yz + zx, x = u - v, y = uv, z = u + v, u, v \in \mathbb{R}.\newline Find \frac{\partial W}{\partial u}, \frac{\partial W}{\partial v} and evaluate them at (1/2, 1).
