The bacteria population doubles in 4 hours.
So, in 1 hour it increases by x/4 of its population, where x is population.
So in 1/2 hours or 30 minutes, the increase will be x/4 × 1/2 = x/8
=> if we start with 4000 bacterias, population increase after 30 minutes is 4000× 1/8 = 500
So, 500 more bacterias were added
Total bacterias = 4000+500 = 4500 bacterias
It should be x=-4 and y= -12
restrict the domains of quadratic functions and absolute value functions, because these functions are
functions. For instance, the quadratic function f(x) = x^2 pairs both −2 and 2 with 4, and the absolute value function f(x) = |x| pairs both −2 and 2 with 2.
Linear functions (excluding constant functions) and exponential functions are
functions, so their domains
to be restricted.
_________________
An absolute value function, without domain restriction, has an inverse that is NOT a function.
In order to guarantee that the inverse must also be a function, we need to restrict the domain of the absolute value function to make it a one-to-one function.
Answer:
18
Step-by-step explanation:
1.5 x 0.25= 6 (for 1 side)
6 x 3= 18 packages.
