A researcher at the Centers for Disease Control and Prevention is studying the growth of a certain bacteria. He starts his exper

steposvetlana [31]

The population of the bacteria after 8 hours is 1639 bacteria.

An exponential function is given by:

y = abˣ

where y, x are variables, a is the initial value of y and b is the multiplier.

Let y represent the population of bacteria after x hours.

Given that he starts his experiment with 500 bacteria, hence

a = 500

The bacteria grow at a rate of 16% per hour, hence:

b = 100% + 16% = 1.16

The exponential equation becomes:

y = 500(1.16)ˣ

After 8 hours:

y = 500(1.16)⁸ = 1639

The population of the bacteria after 8 hours is 1639 bacteria.

PLEASE HELP ME OUT

liubo4ka [24]

Answer:

18.84 ft

Step-by-step explanation:

The formula for the circumference of a circle is C = πd or C = 2πr

We will use C = 2πr since we have r given in the photo

We just need to substitute our values into the formula:
C = 2(3.14)(3) = 18.84 ft

a 12-ft ladder leans against a building so that the angle between the ground and the ladder is 74°. how high does the ladder rea

WINSTONCH [101]

Answer:

12 feet

Step-by-step explanation:

Sometimes, a simple drawing is a great way to start! In the attached drawing, the red line represents the ladder, the brown represents the ground, and the black represents the building!

We want to find the side of the triangle from where the ladder meets the building to where the building meets the ground. This can be found using trigonometric identities, namely sine:

$sin\theta=\frac{opposite}{hypotenuse}$

Plug in known values:

$sin(74^o)=\frac{x}{12}$

Rearrange to isolate the variable:

$x=12sin(74^o)$

Simplify!

$x=11.535140... ft$

Round to the nearest foot:

$x=12ft$

Graph 7/4 on the number line

MakcuM [25]

Answer:

Step-by-step explanation:

First you have to change your fraction:

Change 7/4 into a mixed number

7/4 = 1 3/4

Then you 'guestamate' about 3/4 of the distance between 1 and 2 and mark your point. Like this:
