The number of bacteria on a microscope slide doubles every hour . There are initially 4 bacteria present . Create an explicit function fto model the growth after n hours .

Answers

Answer 1

Answer:

I think a possible equation can be; f(n) = 4(2)ⁿ

f(n) = a * bˣ

Where;

f(n) = the function of f for every n value

a = Initial value (in this case it would be 4)

b = Rate of change (in this case it would be 2, since the bacteria doubles)

x = exponent (in this case it would be n)

So our final equation would be:

f(n) = 4(2)ⁿ

Hope this helps!

ABC is equilateral, each angle has a measure of 9x-12

Answers

Answer:

x=8

Step-by-step explanation:

Angles in a Triangle always add up to 180

So,  3(9x-12)=180

27x-36=180

216=27x

x=8

The angle of the equilateral triangle is 60° and x is 8.

What is a Triangle?

A triangle is a polygon with three sides and three vertices.

The triangle's total number of angles comes to 180°.

Given, measure of angle of an equilateral triangle 9x-12.

The sum of all the angles of the triangle is 180°.

That means,

3(9x-12) = 180°

27x = 180+36

x = 216 / 27

x =8

Therefore, the value of x is 8.

2x         [tex]\huge\checkmark[/tex]

(x - 2)    [tex]\huge\checkmark[/tex]

(x + 6)   [tex]\huge\checkmark[/tex]

Step-by-step explanation:

x² + 4x - 12 = x² - 2x + 2x + 4x - 12

                  = x² - 2x + (6x - 12)

                  = x(x - 2) + 6(x - 2)

                  = (x - 2)(x + 6)

2x² - 4x = 2x(x - 2)

We get

2x² - 4x = 2x(x - 2)

x² + 4x - 12 = (x - 2)(x + 6)

then

The least common denominator is 2x(x - 2)(x + 6)

Answer:

2nd, 3rd and 6th

Step-by-step explanation:

Factorise the denominators of both fractions

x² + 4x - 12 = (x + 6)(x - 2)

2x² - 4x = 2x(x - 2)

The least common denominator is then

Both circles have the same center. The
circumference of the inner circle is
249.944 meters. What is the area of the
shaded region?

Answers

Pretty much to find the area of the shaded region, you have to take the area of the smaller circle, and subtract it from the bigger circle.

First, to find the area of the smaller circle, you can use the circumference given to help you find that. Since the formula for Circumference is C=2rpi, you can solve for the radius by doing 249.944/(2*3.14).

The radius of the smaller circle will end up being 398/15 m as a fraction, and 26.53 rounded to the nearest hundredth.

Now since you have that, you can use the are of a circle formula to find the bigger and smaller circles.

A=pi(r)^2

For the smaller circle: 3.14*(26.53)^2
= 2210.06 meters squared

For the bigger circle: 3.14*(49+26.53)^2
= 17913.01 meters squared


Now subtract them:
17913.01-2210.06 = 15702.95

The area of the shaded is 15702.95

Which property of addition is shown below? a bi c di = a c bi di identity property associative property commutative property inverse property

Answers

The commutative property of addition is shown here a+bi+c+di = a+c+bi+di which is the correct answer.

What is commutative property?

The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the result.

This property applies to multiplication also.

We have the given expression:

a+bi+c+di = a+c+bi+di

We have to identify the property of addition in the above expression.

Since we can say here that (bi+c) is expressed as (c+bi).

The commutative property of addition states that the numbers can be added in any order.

Mathematically, it states that a+b = b+a.

Here, (bi+c) can be replaced by (c+bi), whether 'b' is added to 'ci' or 'ci' is added to 'b', the result is always the same.

Therefore, the commutative property of addition is the correct answer

what is the first step to 11-3x=44 ?

Answers

Answer:

Subtract 11 both sides to isolate the variable and it's cooeficient.

Step-by-step explanation:

Given equation:

11 - 3x = 44

The main goal to determine the solution of the equation is to isolate the variable that is present in the equation.

(1) Subtract 11 both sides to isolate the variable and it's cooeficient.

(2) Simplify if possible.

(3) Divide the cooeficient (-3) both sides to remove the cooeficient from the variable.

Once the variable has been isolated, the opposite side of the variable will be the solution to the variable.

⇒ 11 - 3x = 44

Step-1: Subtract 11 both sides

⇒ 11 - 3x - 11 = 44 - 11⇒ -3x = 44 - 11

Step-2: Simplify (if possible)

⇒ -3x = 44 - 11⇒ -3x = 33

Step-3: Divide the cooeficient of x (-3) both sides

⇒ -3x = 33⇒ -3x/-3 = 33/-3⇒ x = -11

Therefore, the first step in simplifying the expression (11 - 3x = 44) is to subtract 11 both sides to isolate the variable and it's cooeficient. When the expression is simplified, we get the solution x = -11.

Answers

The probability that the first three cards that he deals are all hearts if none of them are replaced will be [tex]\rm P = \frac{13}{52} \times \frac{12}{51} \times\frac{11}{50}[/tex].

What is probability?

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.

Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

The given data in the problem is ;

Total number of the card in the deck = 52

No of hearts = 13

If one heart is taken out one at a time we will get the probability that the first three cards that he deals are all hearts if none of them are replaced

From the total card one by one the cards is taken out without the replacement;

Without replacement, the card will be reduced by 1Also the heart card will also be decreased by one.

The probability that the first three cards that he deals are all hear will be;

[tex]\rm P = \frac{13}{52} \times \frac{12}{51} \times\frac{11}{50}[/tex]

What is Histogram?

A histogram is a graph that depicts the frequency distribution of a few data points from a single variable. Histograms frequently divide data into "bins" or "range groups" and count the number of data points that belong to each of those bins.

The bar graph graphically represents category data. A histogram is a graph that represents quantitative data. Each pair of consecutive bars is separated by an equal amount of space.

The data from the Histogram can written as

Age group   Number of Children

 1 - 3                         5

 3 - 5                         3

What is a standard deviation?

The standard deviation is the maximum and the minimum variation in the data set from the mean.

Given that the mean shoe size is 7.5, while the size of shoe for the entire class is only 1 deviation, and the value is 6 and 9. Therefore, the equation of the standard deviation and the mean can be written as,

[tex]\mu -\sigma < x < \mu +\sigma \\6 < x < 9[/tex]

Now, the value of the standard deviation can be written as,

[tex]\mu - \sigma = 6\\\\-\sigma = 6-7.5\\\\-\sigma = -1.5\\\\\sigma = 1.5[/tex]

or the value of the standard deviation can be written as,

[tex]\mu + \sigma = 9\\\\ \sigma = 9-7.5\\\\ \sigma = 1.5[/tex]

Hence, the value of the standard deviation is 1.5.
