Recreational time can come before or after school True or False

Complete Question:

You can model the population of a certain city between 1955-2000 by the radical function

P(x) = 55,000 sqrt x-1945

Using this model, in which year was the population of that city 275,000?

Answer:

In 1970 population of that city is 275,000

Solution:

Given that,

You can model the population of a certain city between 1955-2000 by the radical function :

P(x) = 55000\sqrt{x - 1945}

To find: year in which was the population of that city 275,000

Therefore,

x = ?

P(x) = 275000

Thus we get,

275000 = 55000\sqrt{x - 1945}\\\\Divide\ both\ sides\ by\ 55000\\\\\frac{275000}{55000} = \sqrt{x-1945}\\\\5 = \sqrt{x - 1945}\\\\Take\ square\ on\ both\ sides\\\\25 = x - 1945\\\\x = 1945 + 25\\\\x = 1970

Thus, in 1970 population of that city is 275,000

The answer is A. 1970.

Answer:

as being 3 days old

Explanation:

In this specific scenario, the food worker should label the food as being 3 days old. This is because when working in the food industry, the food needs to be labeled with the date of the oldest cooked ingredient. In this case, it would be the chicken.

When foods are unfrozen or cooked, microorganisms begin growing on the foods surface and more enzyme activity begins to take place. This increases the rate at which the food ultimately spoils. Chicken for example is safe to eat, up to 4 days after it has been cooked according to the CDC.

Therefore, the food worker should label the food as being 3 days old to comply with the food industry regulations as well as make sure that the food does not pass its expiry timeframe and is sold. Which can cause someone to become sick.

How the food worker should label the chicken salad

The food worker should label the chicken salad 3 days ago

Labelling of food should be done according to how long the food has been prepared. This is to ensure that food cooked a long time ago is served first before serving food cooked recently.

When cooked food are kept for too long, germs grow on it which causes food poisoning or food wastage.

Answer:

 λ = -47 nC / m  

Explanation:

The missing question is as follows:

" The potential difference between the surface of a 2.2 cm -diameter power line and a point 1.9 m distant is 3.8 kV. What is the magnitude of the line charge density on the power line? Express your answer using two significant figures.  "

Given:

- The Diameter of the power line D = 2.2 cm

- The distance between two ends of power line L = 1.9m

- The potential difference across two ends V = 3.8 KV

Find:

What is the magnitude of the line charge density on the power line?

Solution:

- The derivation of the line of charges for a length L oriented along any axis centered at origin and the potential difference between two ends is as follows:

                                      V = 2*k*λ*Ln( D / L )

Where,

k : Coulomb's Constant = 8.99*10^9

 λ : The line charge density

- Re-arrange and solve for λ:

                                     λ = V / 2*k*Ln( D / L )

Plug in the values:

                                    λ = 3800 / 2*8.99*10^9*Ln( 2.2 / 190 )

                                    λ = -4.74022*10^-8 C / m

                                   λ = -47 nC / m  

Answer:mollusks, echinoderms, chordates, and annelids

Explanation: Cladograms are diagrams made to link different organisms to a common ancestor, with the use of Cladograms the relationship between organisms will be established and organisms will be grouped together based on their common features or characteristics.

Molluscs, Echinoderm,Chordates and annelids are of a common ancestor, they are all invertebrates with COELOM.

Mollusks, echinoderms, chordates, and annelids have a common ancestor.

What is a Cladogram?

This can be defined as diagrams which help to link different organisms to a common ancestor based on common features or characteristics.

The organisms mentioned above are all invertebrates with a Coelom which means they are from a common ancestor.
