If B is the midpoint of AC, and AC= 8x-20, find BC.
Semmy [17]

Answer:

BC = 4x-10

Step-by-step explanation:

\because B is the midpoint of AC.

\therefore BC = \frac{1}{2} AC

\therefore BC = \frac{1}{2} (8x-20)

\therefore BC = \frac{1}{2} \times 2(4x-10)

\huge \purple {\boxed {\therefore BC = 4x-10}}

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
