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.

Ray ML and MN are perpendicular. ray MP ia an angel bisector. find the value of x .​
bulgar [2K]

Answer: x = 15

Step-by-step explanation:

First, we will have to acknowledge that Angle M is a complementary angle (that means that it is 90 degrees) meaning that 2x° + 4x° will equal 90 degrees. So, let’s set up this equation.

90 = 2x + 4x

90 = 6x

\frac{90}{6} = \frac{6x}{6}

15 = x

Therefore, the x is 15.
