You want to know how long it'll take for the bacteria to grow
to (800/500) = 1.6 times their initial population.

The number of double-times it'll take is 

                         [ log(1.6) / (log(2) ]  =  0.6781 .

The double-time for these particular critters is 12 hours,
so it'll take them

                             0.6781  x  12 hours  =  8.137 hours

                                                                =  8 hours  8.2 minutes .

Write an equation for the line passing through the points (0,3) and (-9,0) using Y=mx+b format.
Valentin [98]

Answer:

y = \frac{1}{3}x + 3

Step-by-step explanation:

y = mx + b

y = mx + 3 (the y-intercept was given (0,3))

\frac{3 - 0}{0 + 9} = \frac{3}{9} = \frac{1}{3}

y = \frac{1}{3}x + 3

Simplify the expression IabI if a>0 and b>0
Brums [2.3K]

Answer:

Step-by-step explanation:

The "ab" inside absolute value has to go out positive, such as |-2|=2

Since both the a and b values are positive, the value of |ab| should be "ab"

For example:

a=2

b=3

|ab| = |2*3| = |6| = 6
