Answer:
a) Q(t) = 89 + 12t
b) Q(3) = 125 millions of bacteria
Step-by-step explanation:
a)
to write a function of the growth of bacteria, we need to consider the initial population and add it to the new bacteria. Also we need to consider that the result of the function is in millions of bacteria, so when we get a result, we express it in millions.
Data
Initial population = 89 just add it to the function given 12t
Q(t) = 89 + 12t
b) Data time = 3 h
Q(3) = 89 + 12(3) substitution
Q(3) = 89 + 36 simplifying
Q(3) = 125 millions of bacteria

Answer:
The answer will be D.y=-2
Step-by-step explanation:
The reflection line is the fixed line that a shape or figure is reflected across of. The problem tells you that the triangle is reflected across y=-2
Parallel lines have the same slope.
We have the line y = 3/4x + 1.
Then the equation of a parallel line is y = 3/4x + b.
The line passes through the point (4, -2). Put the coordinates of the point to the equation of a line:
-2 = 3/4(4) + b
-2 = 3 + b <em>subtract 3 from both sides</em>
-5 = b
<h3>Answer: y = 3/4x - 5</h3>
Answer:
1.1(for infinity) or 0.9
Step-by-step explanation:
it depends if you do 90/100 or 100/90
90/100 = 0.9
100/90 = 1.1(for infinity)
so sorry i couldn't figure out specifically what to divide but i hope both of these answers helped you!
