The number of students in an school building that have the flu after t days is given by the function

gulaghasi [49]

Step-by-step explanation:

$p(0) = \frac{800}{1 + 49 {e}^{ - 0.2 \times 0} } = \frac{800}{1 + 49} = \frac{800}{50} = 16$

$200 = \frac{800}{1 + 49 {e}^{ - 0.2t} } \\ 200(1 + 49 {e}^{ - 0.2t} ) = 800 \\ 200 + 9800 {e}^{ - 0.2t} = 800 \\ 9800 {e}^{ - 0.2t} = 600 \\ {e}^{ - 0.2t} = \frac{3}{49} \\ ln( {e}^{ - 0.2t} ) = ln( \frac{3}{49} ) \\ - 0.2t = - 2.793 \\ t = 13.96 = 14$

What is the slope of the line passing through (1, 2) and (3, 8)?

saveliy_v [14]

Answer:

Option C is correct.

Step-by-step explanation:

Points given are

(1,2) and (3,8)

The formula used for slope is:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

x₁ = 1, x₂=3, y₁=2 and y₂=8

$m=\frac{8-2}{3-1}\\m=\frac{6}{2}\\m=3$

So, slope =3

Option C is correct.
