In a petri dish, a certain type of bacterium doubles in number every 45 minutes. There were originally 32, or 2^5 bacteria in the dish. After 180 minutes, the number of bacteria has doubled 4 times, multiplying by 2^4. Now the population of bacteria is 2^5 • 2^4. Expressed as a power, how many bacteria are in the petri dish after 180 minutes?

A.) 2^4
B.) 2^20
C.) 4^9
D.) 2^9​

Answer:

1x + 4

Step-by-step explanation:

-5x- 3x+ 4+ 9x

first you add -5x and -3x

which is

-8x

-8x + 4 + 9x

now you add -8x and 9x

which is

1x

final answer is

1x + 4

Answer:

-5x,-3x, and 9x

Step-by-step explanation:

these are like terms because they all have an x at the end. say there was a number like 7xb and 6xb, they would be like terms, however, if you have 3x and  3xb, they would not be like terms. When you have like terms you can combine them together. So for this, it would be

1x+4

Answer:

#1 is the only relation that is a function.

Step-by-step explanation:

The definition of a function is that every x value (within the interval; for continuous functions) has one y value.  This means that one x value CANNOT have two y values and still be a function.  You can use the vertical line test, do this by imagining a vertical line going up and down the graph.  If that line touches two or more points, then that means there are more than 1 y value for at least one of the x values.  That is a quick way to determine if it's a function.  Only #1 passes this test.

Answer:

28/9

Step-by-step explanation

The solution of the inequality 5 - (3/2)x > 1/3 for x will be x < 28/9.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

As per the given inequality,

5 - (3/2)x > 1/3

5 > 1/3 + (3/2)x

(3/2)x < 5 - 1/3

(3/2)x < 14/3

x < 28/9

Hence "The solution of the inequality 5 - (3/2)x > 1/3 for x will be x < 28/9".

Answer:

0.4

Step-by-step explanation:

Put 40 over 100 and simplify = 4/10, divide both by 2 = 2/5

now divide 2 by five which equals 0.4

Answer:

See explanation

Step-by-step explanation:

Given that the correct point-slope form is;

y - b = m(x - a)

So she made an error in writing y + 1, that part is wrong.

So the equation that was written wrongly is;  y+1=1/2(x−3)

We have to rewrite the entire equation;

y - 1 = 1/2(x - 3)

If they are growing at a rate of 25% every day you can expect to have approximately 100 cockroaches in your living room.

Growth rate refers to the rate at which something (such as a population, a quantity, or a value) increases or decreases over a certain period of time.

Assuming that the growth rate is compounded daily, we can calculate the number of cockroaches you will have after three days using the formula for exponential growth:

[tex]N = N_0(1 + r)^t[/tex]

Where:

N₀ is the initial number of cockroaches (64 in this case)

r is the growth rate (25% or 0.25 in decimal form)

t is the time in days (3 in this case)

N is the number of cockroaches after t days

Plugging in the values, we get:

[tex]N = 64(1 + 0.25)^3[/tex]

[tex]N = 64(1.25)^3[/tex]

N = 64(1.5625)

N = 100

Thus, after three days, you can expect to have approximately 100 cockroaches in your living room.

Answer:

806 million years

Step-by-step explanation:

From the information given:

Firstly, we need to determine the no. of ways we can choose n many words in the dictionary & array them in [tex](^{171476}_{n}) * n![/tex] ways.

Thus, the no. of unique books possible of length till K is:

[tex]\sum \limits^k _{n=0} ( ^{171476}_{n}) * n! \\ \\ = \sum \limits ^k_{n=0} \dfrac{171476!}{(171476-n)!}[/tex]

where K = 6, we have the value to be:

= 25420530373932821216635722990977

Thus, the time required to write all possible texts of 6 is:

=  (25420530373932821216635722990977)/10⁶

≅ 806 million years.

Answer:

There isnt a possible answer because there is no whole

Step-by-step explanation:

if it was for example 5(y+3)=55

then you could simplify it to 5y+15=55

then 5y=40

y=8

Answer: 14.29 shops

Step-by-step explanation:

Total number of shops:

= 30 + 28 +16 + 14 + 10 + 7 + 3

= 108 shops

Median position = 108/2 = 54

Median is in range where cumulative number of shops is 54.

Range is: More than or equal to 10

Median = Lower limit of median range + range of median range * (median position - cumulative frequency up to median range) / frequency of median range

=  10 + 5 * (108/2 - 30) / 28

= 10 + 4.29

= 14.29 shops

Answer:

Step-by-step explanation:

(x₁, y₁)  = (-9, 7)    & (x₂ , y₂) = (9 , -3)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

          [tex]= \frac{-3-7}{9-[-9]}\\\\= \frac{-3-7}{9+9}\\\\=\frac{-10}{18}\\\\= \frac{-5}{9}[/tex]

Answer: The factory owner would want to use Graph B to show the rapid rise in his employees wages because Graph B shows greater increase in slope

Step-by-step explanation:

The question and the options are mismatched. Answer to the question is given above.

The factory owner would like to show that worker's wages are rising rapidly even though they are not.

The factory owner's best bet therefore is to use Graph B because it has a greater slope which might fool people into believing that the wage rates are rising rapidly which is what led to the greater increase in slope size.

The options most probably allude to a question asking what graph an employee representative would use to show that the wages are not increasing rapidly and the answer to that would be option D because graph A has a smaller slope.
