A dorm at a college houses 1600 students. One day, 20 of the students become ill with the flu, which spreads quickly. Assume that the total number of students who have been infected after t days is given by N(t)= 1100/1+19e^-0.65t

a) After how many days is the flu spreading the fastest? (Do not round until the final answer. Then round to two decimal places as needed.)

b) Approximately how many students per day are catching the flu on the day found in part (a)? (Round to the nearest whole number as needed.)

c) How many students have been infected on the day found in part (a)?

Please write out the steps :)

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

d 600 because 15*10*2=300

300+300=600
