I need help A biologist is studying the effects of using a type of bacteria to clear drain pipes. She creates a simulation of a typical kitchen drain system and uses it regularly for three days before introducing the bacteria. She then carries out her simulation for another 15 days. The population of bacteria can be approximated using function b, where d is the number of days since she started the experiment and is the bacteria population in hundreds.

Use this information to complete the statement.

The domain over which the bacteria population increases is ___ _< d _< ___.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
