1. How many milliliters of a 1:20 w/v solution of copper sulfate should be used to prepare 1 L of a 0.50% w/v solution?

2. How many grams of lidocaine should be added to a 2 % lidocaine ointment to prepare 1000 g of 5% of lidocaine ointment? (Mixing pure lidocaine and 2% lidocaine ointment)

Endotracheal and Tracheostomy Suctioning

1.Make a table and indicate ‘When To Perform Suction and in Whom’, then the other column would include ‘When NOT To Perform Suction.’

2. Watch the following videos:

a.https://www.youtube.com/watch?v=jOkO2lfny5A

b.https://www.youtube.com/watch?v=ern1Z77DUVo

Make a reflection about these two procedures by writing a minimum of 200-300 words essay.

1. Vector u =< 0,−1,3 > is given. Find a non zero vector v which is perpendicular to u. Then find a vector w which is perpendicular to both u and v. Explain the reason for your selection clearly.

2. Find the slope of the tangent line to the parametric curve x = 5 + sin(3θ) and y = −3 + 2tanθ at θ = π.

1.) Find the sum V in cartesian and polar coordinates of V1=1000 m/s, V2=1800 m/s 2.) Find the difference of V in polar and cartesian coordinates for V3= 800 m/s and V4= 1400 m/s. The angles are angle1= 35 deg, angle2= 60 deg, angle3= 130 deg, angle4= 340 deg.

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?

Express your answer to two significant figures and include the appropriate units.

A small mailbag is released from a helicopter that is descending steadily at 1.69 m/s.

(a) After 3.00 s, what is the speed of the mailbag?

v =  m/s

(b) How far is it below the helicopter?

d =  m

(c) What are your answers to parts (a) and (b) if the helicopter is rising steadily at 1.69 m/s?
