Answer: [c, ∞)

Step-by-step explanation:

Range is all of the y-coordinates.

The parabola is upright (∪) because the coefficient of x² is positive.

So the minimum value is at "c" and the parabola tends toward infinity.

Range: y ≥ c in Interval Notation: [c, ∞)

Answer:

The size of the sample after four hours is of 3158 bacteria.

Step-by-step explanation:

The population after t hours can be modeled by the continuous exponential growth model, which is:

$P(t) = P(0)e^{rt}$

In which P(0) is the initial population and r is the growth rate paremeter.

A growth rate parameter of 17% per hour.

This means that $r = 0.17$

Suppose also that a sample culture of 1600 is obtained from this population.

This means that $P(0) = 1600$

Find the size of the sample after four hours.

This is P(4).

$P(t) = P(0)e^{rt}$

$P(t) = 1600e^{0.17t}$

$P(4) = 1600e^{0.17*4}$

$P(4) = 3158.2$

Rounding to the nearest integer

The size of the sample after four hours is of 3158 bacteria.

7.8 X 103 -------------- 1.2 X 104

Strike441 [17]

;-;

Let's just do a bunch of math below.

7.8 X 103 ?

-------------- = ------

1.2 X 104 ?

So, first, we're gonna do 7.8 multiplied by 103 to get 803.4.

Thus....

7.8 X 103 803.4

-------------- = -----------

1.2 X 104 ?

Then we would do 1.2 multipied with 104 to get a product of 124.8.

Therefore....

7.8 X 103 803.4

-------------- = -----------

1.2 X 104 124.8

Dividing 803.4 by 124.8 would get you a quotient of 6.4375.

Your answer is 6.3475.~

Have a nice day~
