136 = 2x^2 + 8
128 = 2x^2
64 = x^2
8 = x
Answer:
The correct option is D.
Step-by-step explanation:
It is given that the population of bacteria begins with 1 bacterium and triples every hour.
Let initial population be 1.
The population of bacteria after 1 hour is
The population of bacteria after 2 hour is
Similarly the population of bacteria after n hour is
If x is number of hours and y is the population of bacteria after x hour, then
The other way to find the population model is shown below.
The population model is defined as
Where, a is initial population and (1+b) is growth factor.
In the given situation the initial population is 1 and growth factor is 3, therefore
Therefore option D is correct.
Answer:
45°
Explanation:
AngleMR is 90° which means Angle MP and angle X have to be equivalent and all three angles add up to 180°, making angle X equal to 45°
The coordinates (abscissa and ordinates) of the midpoint of the line segment is the average of the abscissas and the ordinates, respectively. Therefore, the x - coordinate of the midpoint is equal to -20 + 20 or 0 by 2 which is zero. The answer is letter E.
