Someone please help me
Troyanec [42]
Pythagorean theorem is a^{2} + b^{2} = c^{2}
and using that sin is opposite/hypotenuse, you can find the third side of the triangle.
11^{2}+(adjacent)^{2} = 61^{2} \\ 121+ (adjacent)^{2} = 3721 \\ (adjacent)^{2}=3600 \\ adjacent = 60
now you know adjacent is 60, so cos=60/61

The spread of a flu virus on a college campus is modeled by y= 5000/(1+4999e^-0.8t), where y is the number of students infected
Darina [25.2K]

Answer:

537 students

11 days

Step-by-step explanation:

       5000

y=  -----------------

    (1+4999e^-0.8t)

a)  after 8 days  means t =8


       5000

y=  -----------------

    (1+4999e^-0.8*8)

       5000

y=  -----------------

    (1+4999e^-6.4)

       5000

y=  -----------------

    (1+8.306)

       5000

y=  -----------------

    (9.306)

y =537.28

Rounding to the nearest student

y = 537 students


b)  1/2 the student population  means y =2500  (The 5000 is the student population)

             5000

2500=  -----------------

        (1+4999e^-0.8t)

Multiply each side by  (1+4999e^-0.8t)

2500 (1+4999e^-0.8t) = 5000

Divide each side by 2500

(1+4999e^-0.8t) = 5000/2500

(1+4999e^-0.8t) = 2

Subtract 1

(4999e^-0.8t) = 2-1

(4999e^-0.8t)=1

Divide by 4999

(4999/4999e^-0.8t)=1/4999

e^-0.8t=1/4999

Take the natural log of each side

ln(e^-0.8t)=ln(1/4999)

-.8t = ln(1/4999)

Divide by -.8

-.8/-8t = -1/.8 *ln(1/4999)

t = -1/.8 *ln(1/4999)

t≈10.6462

Rounding, it will take 11 days
