The total number of people, P, who have been infected with a contagious virus t weeks after the epidemic began is given by the following formula. 1620 1+4(0.5) Complete parts a through d below a. How many people originally had the virus? Originally people were infected.

Originally 324 people were infected.

Step-by-step explanation:

Given the function

P = 1620/(1 + 4(0.5)^t)

Where;

P is the total number of people, who have been infected with a contagious virus t weeks after the epidemic began.

t is the number of weeks after the epidemic began.

To determine the number of people who originally have the virus. At this time

t = 0

Therefore, substituting t = 0 into the function of P

P = 1620/(1 + 4(0.5)^0)

P = 1620/(1 + 4)

P = 324 people.

Originally 324 people were infected.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
