A metric space X is said to be locally path-connected if for every x ∈ X and every open neighborhood V of x in X, there exists a path-connected open neighborhood U of x in X with x ∈ U ⊂ V.
(a) Show that connectedness + local path-connectedness ⇒ path-connectedness
(b) Determine whether path-connectedness ⇒ local path-connectedness.

The inverse demand function for a product by a company that montizes the market is given by v = 200 - 0.03m and supply is given by v = 0.05m
a) Draw and calculate market balance (show price & quantity and a picture)
b)The product damage to society is 70$ per unit. The government uses Pigovjan tax on the production of the company. Update the picture from a) in regards to the Pigovjan tax/1b.

After watching the selected videos, discuss the importance of "keeping score" in business. Discuss what information should be shown and to whom it should be shown. Why did the man in the first video look through the wall? Are employees like that? How can management maintain that level of excitement?

An electron is accelerated horizontally from rest by a potential difference of 2100 V . It then passes between two horizontal plates 6.5 cm long and 1.3 cm apart that have a potential difference of 200 V
At what angle θ will the electron be traveling after it passes between the plates?

The concentration of NO3– in a water sample is determined by a onepoint standard addition using a NO3– ion-selective electrode. A 25.00-mL sample is placed in a beaker and a potential of 0.102 V is measured. A 1.00-mL aliquot of a 200.0-mg/L standard solution of NO3– is added, after which the potential is 0.089 V. Report the mg NO3–/L in thewater sample.
