In a lab experiment, 80 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 17 hours. How many bacteria would there be after 20 hours, to the nearest whole number?
Answers
Answer:
y = 181
Step-by-step explanation:
Doubling Formula:
[tex]y = a(2)^\frac{t}{d}[/tex]
y=80
d=17

D) [tex]8g^{6} h^{4} k^{12} -h^{25}k^{15}[/tex]
Step-by-step explanation:
You have to use the laws of exponents to solve this:
Power of a Power: [tex](a^{m} )^{n} = a^{mn}[/tex]. In this case, [tex](4g^{3} h^{2} k^{4} )^{3}[/tex], all of the numbers in the parenthesis need to be multiplied to the power of 3: [tex]4^{3} g^{9} h^{6} k^{12}[/tex].
Quotient of Powers: [tex]\frac{a^{m} }{a^{n} } = a^{m-n}[/tex]. In this case, [tex]\frac{4^{3} g^{9} h^{6} k^{12}}{8g^{3} h^{2} }[/tex], all of the exponents need to be subtracted (but the 4³ (64) and 8 need to be divided): [tex]8g^{6} h^{4} k^{12}[/tex].
Use the Power of a Power again for the expression at the right: [tex](h^{5} k^{3} )^{5}[/tex]. You get: [tex]h^{25} k^{15}[/tex]. Keep the subtraction/negative sign where it is.
Together, you get: [tex]8g^{6} h^{4} k^{12} -h^{25}k^{15}[/tex].
Hope it helps!
Determine if the graph is a function then state the domain and range.
Answers
A function is a set of relation that doesn't have repetitive domain. If we want to know if a graph is function or not, we have to do the line test.
Line Test
Draw a vertical line. Make sure that a line passes through a graph.See if a line intercepts a graph more than one point or just only one.Result
If a line intercepts a graph more than one point, it is not a function.
However, if a line only intercepts a graph just one point, it is indeed a function.
The given graph from the question is a function because it passes line test.
Domain and Range
Domain is the set of all x-values, meaning we only focus on x-axis or x-value only.
Range is the set of all y-values. We only focus on y-value or y-axis for Range.
Determine Domain from Graph
We can simply say that the domain is from starting domain or x-coordinate point to end x-coordinate point. For example, if a graph starts at x = -4 and ends at x = 2, we can say that - 4<=x=2.
Determine Range from Graph
Similar to Domain except Range starts from the minimum value or point to the maximum point or value. For example if a graph starts at min point = 6 and max point = 9. We can say that 6<=y<=9.
From the graph, the domain starts from negative infinity to positive infinity. Meaning that x can be any numbers. Hence, the domain is set of all real numbers. For range, the minimum value is 0 and max value is positive infinity. Therefore we write y>=0.
Answer[tex] \begin{cases} x \in \mathbb{R} \\ y \geqslant 0 \end{cases}[/tex]
Domain is set of all real numbers.
Range is greater or equal to 0.

Step-by-step explanation:
At midnight, the temperature in a city was 5 degrees Celsius. The temperature was dropping at a steady rate of 2 degrees Celsius per hour.
Write an inequality that represents t, the number of hours past midnight, when the temperature was colder than -4 degrees Celsius. Explain or show your reasoning.
Show all the values of t that make your inequality true on a number line, like the one shown below.
A number line with the numbers negative 4 through 10, in increments of 2, indicated.
Answers
Answer:
(5-2t)<-4
Step-by-step explanation:
The temperature is 5 °C at midnight, and it is dropping at a speed of 2 °C each hour. If it's past midnight, the temperature will be t degrees after t hours ( 5 - 2t ). If the temperature is below - 4 ℃, the inequality can be ( 5-2t ) - 4

To determine the number of deer in a forest, a naturalist catches, tags, and releases 15 deer. Later, 20 deer are caught, and 6 have tags. Estimate the number of deer in the forest.
Answers
Answer:
50 deer in the forest.
Step-by-step explanation:
Since this is a ratio problem and we are given three values and a single unknown (total number of deer) we can use the Rule of three to solve for the variable. We do this by multiplying the diagonal values and then dividing by the last available value. That will give us the value of the variable which in this case would be represented as x.
20 deer <======> 6 tagged
x deer <======> 15 tagged
(20*15) / 6 = x
300 / 6 = 50 total deer
Based on these values we can estimate that there are a total of 50 deer in the forest.
a reflection of the pink triangle is shown. which transformation makes this reflection
Answers
Answer:
A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a fixed line.

Cora bought 80 feet of cable for $18.40. She needs 20 more feet. If the unit price is the same, how
much will she pay for the extra 20 feet of cable?
She will pay an extra $
Answers
Answer:
Step-by-step explanation:
20ft($18.40/80ft)=$4.60
Answer:
$4.6
Step-by-step explanation:
Use 18.40 and 80. if $18.40 is 80 feet, divide 18.40 by 4 to get 4.60. Now you know that you got 4.60, see if you can add 4.6 four times to get to 18.4. (You can.) So, 20 feet is $4.60 or $4.6.

Mariam is a waitress at a restaurant. Each day she works, Mariam will make a guaranteed wage of $30, however the additional amount that Mariam earns from tips depends on the number of tables she waits on that day.

How much would Mariam expect to make in a day when waiting on t t tables?
Answers
Answer:
19 tables = $201
t tables = 9t+30
Step-by-step explanation:
the slope would be 9 because she gets $9 for each table (t), 30 would be the y-intercept because she will always get that amount each week.
Insert 19 to equation:
y(t) = 9(19) + 30

201

Would it be better to have a loan with 5% interest payback in 2 years, or a loan with 2% interest paid back in five years? Explain. Show work to justify your answer.
Answers
Step-by-step explanation:
If the interest on the loan is simple interest. Both the situation will have equal amount of interest ( 5*2 =10% of total amount). Therefore, it would be better to pay back with 2% interest paid back in five years. However, if the interest is compounded annually, 5% in 2 years will have lesser interest than 2% in 5 years. Hence, Former option would be better.
