A bacteria population doubles every 4 hours. There are currently 2,000 bacteria in a restricted area. If t represents the time, in hours, and P(t) is the population of bacteria with respect to time, about how many bacteria will there be in 30 minutes?

Answers

Answer 1

The bacteria population doubles in 4 hours.

So, in 1 hour it increases by x/4 of its population, where x is population.

So in 1/2 hours or 30 minutes, the increase will be x/4 × 1/2 = x/8

=> if we start with 4000 bacterias, population increase after 30 minutes is 4000× 1/8 = 500

So, 500 more bacterias were added

Total bacterias = 4000+500 = 4500 bacterias

The formula W = Fd shows the relationship between work, force, and distance. Solve this formula for distance.

Answers

Answer:

[tex]d = \frac{W}{F}[/tex]

Step-by-step explanation:

To do this, we must isolate the variable d.

W = Fd

To isolate d, we must divide the variable F from both sides.

W ÷ F = Fd ÷ F

W ÷ F = d

Now that we have isolated the variable d, we have successfully solved this formula for distance.

[tex]d = \frac{W}{F}[/tex]

Answer:

d = W/F.

Step-by-step explanation:

You simply divide both sides by F:

W / F = Fd / F

W/F = d.

Please answer ASAP. You begin with 1/2 scoop of ice cream. Since you're hungry, you ask the vendor for 2/7 more scoops of ice cream. Then, you eat 5/8 scoops. How many scoops of ice cream are left on your cone? I will mark Brainliest for first correct answer.

Answers

Answer:

9/56

Step-by-step explanation:

[tex] \frac{1}{2} + \frac{2 }{7} - \frac{5}{8 } = \frac{9}{56} [/tex]

First, let’s get our names straight. We’re dealing with three different size pieces: halves, sevenths, and eighths. The least common denominator (size) between these three is 7 • 8 = 56, and converting our fractions over to this new name gets us

1/2 = 28/56
2/7 = 14/56
5/8 = 35/56

We start with 28/56, and adding 16/56 gets us 44/56. Then, we eat 35/56 of the scoops, giving us 44/56 - 35/56 = 9/56 of our original scoops by the end.

Give a reason to justify the equation. 3 • (10 • 12) = (3 • 10) • 12

Answers

Final answer:

The equation 3 • (10 • 12) = (3 • 10) • 12 is justified by the associative property of multiplication, stating that the grouping of numbers in multiplication does not change the outcome.

Explanation:

The equation 3 • (10 • 12) = (3 • 10) • 12 can be justified using the property of associative property of multiplication. This property states that when three or more numbers are multiplied, the way in which the numbers are grouped does not change the product. In simpler terms, no matter how we place the parentheses in a multiplication equation, the result will always be the same.

For example, let's take three numbers, a, b, and c. The associative property of multiplication tells us that (a • b) • c = a • (b • c). Applying this to the given equation, 3 • (10 • 12) is the same as (3 • 10) • 12 because, according to the property, the grouping of numbers does not affect the outcome. This demonstrates why the original equation holds true.

Which of the following functions will produce the graph shown below?

Answers

ANSWER

The answer is B.

[tex]y = \frac{ {x}^{2} - 1}{ {x}^{2} + 2x - 3 } [/tex]

EXPLANATION

The graph represents a rational function.

This rational function has a hole at x=1 and a vertical asymptote at x=-3.

This implies that the denominator of the rational function in factored form is

[tex](x + 3)(x - 1)[/tex]

When we expand this, we get:

[tex] {x}^{2} + 2x - 3[/tex]

This tells us that the answer must be option B.

This graph also has a horizontal asymptote at y=1.

The numerator must therefore have leading term that is quadratic with the coefficient being unity or 1.

Therefore the function is actually

[tex]y = \frac{ {x}^{2} - 1}{ {x}^{2} + 2x - 3 } [/tex]

The value of Sin θ for a given circle and given condition is (2√5)/5.

What is Circle?

A circle is the set of all points in the plane that are a fixed distance (the radius) from a fixed point (the center). Any interval joining a point on the circle to the center is called a radius.

Here, let the horizontal side be x.

         vertical side be y

then as per the given condition

Vertical distance = 2 X horizontal distance

      y = 2x

By Pythagoras Theorem,

      r = [tex]\sqrt{x^2+y^2}[/tex]

      1 = [tex]\sqrt{x^2+(2x)^2}[/tex]

      1 = x² + 4x²

      5x² = 1

       x² = 1/5

      x = 1/√5

then, y = 2/√5

Now, Sin θ = perp. / Hypo.

         Sin θ = y/1

           Sin θ  = 2/√5

or        Sin θ  = (2√5)/5

Thus, the value of Sin θ for a given circle and given condition is (2√5)/5.

Part A: Describe the data you would expect her to collect from this question. (5 points) Part B: Explain whether this is a statistical question. If this is not a statistical question, then modify the question to make it statistical. (5 points)

Answers

A. You would just get a lot of names back from people, thinking they have the most time playing instruments.

B. This question is not a statistically accurate question if you would like statistical answers back.

Statistical question definition:

A statistical question is one that can be answered by collecting data and where there will be variability in that data. For example, there will likely be variability in the data collected to answer the question,

The question to ask to get statistical answers back would be: How many hours do you play the instrument a day?

Each student would answer and you would see who has the most hours.

Final answer:

Minnie should collect quantitative data on the hours spent playing instruments by her classmates to determine who spends the most time. The original survey question is not statistical because it does not allow for analysis of a group trend, but changing the question to inquire about the typical number of hours spent by students each week would make it statistical.

Explanation:

Part A: Expected Data Collection

The data Minnie would expect to collect from her survey question would consist of quantitative information. Specifically, she should gather the number of hours each classmate spends playing musical instruments per week. This data allows her to determine which student spends the most time practicing.

Part B: Statistical Question Analysis

The question, "Which student spends the most time playing musical instruments?" is not a statistical question because it seeks a singular answer rather than understanding a trend, variation, or distribution within a group. To make it statistical, the question could be modified to: "How many hours do students typically spend playing musical instruments each week?" This revised question allows for the collection, analysis, and interpretation of data, which can lead to conclusions about the musical habits of Minnie's classmates.

Step-by-step explanation:

The diagonal divides the flag into 2 right triangles.

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse (diagonal ) is equal to the sum of the squares on the other 2 sides.

let x be the length, then

x² + 9² = 15²

Find Percent increase or Percent Decrease
Question
The price of a share of one stock rose from $12.50 to $50. Find the percent increase
Provide your answer below:

Answers

300%? Since 50 minus 12.50 equals 37.5 and 12.50 times 300% equals 37.5 so if you add 12.50 and 37.50 it equals 50
Final answer:

The increase in price of the stock is $37.50. To find the percent increase, divide the increase (37.50) by the original price (12.50) and multiply by 100, giving a percent increase of 300%.

Explanation:

The question requires us to find the percent increase in the price of a stock. First, to find the increase, we subtract the initial price from the final price. We get $50 - $12.50 = $37.50. This is the increase in price. To find the percentage increase, we divide this increase by the initial price and multiply by 100 to convert it into percent. Therefore, the percentage increase = ($37.50 / $12.50) x 100 = 300%. Therefore, there is a 300% increase in the stock price.

Type in the correct answer. What is the slope of line m?

Answers

Answer:

[tex]-\dfrac{1}{2}[/tex]

Step-by-step explanation:

In the given graph of straight line to find the slope of the line.

First we choose two points on line and then using formula to find the slope.

Formula:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Point on line from graph: (2,-1)  and (-2,1)

[tex]x_1\rightarrow 2[/tex]

[tex]y_1\rightarrow -1[/tex]

[tex]x_2\rightarrow -2[/tex]

[tex]y_2\rightarrow 1[/tex]

Substitute the points into formula

[tex]m=\dfrac{1+1}{-2-2}[/tex]

[tex]m=-\dfrac{1}{2}[/tex]

Hence, The slope of the line is [tex]-\dfrac{1}{2}[/tex]

The slope (m) of the line passing through the points (-2, 1) and (2, -1) is -1/2.

The slope of a line is a measure of its steepness or incline. It determines how much the line rises or falls for each unit of horizontal change. Mathematically, the slope is defined as the ratio of the vertical change (the difference in y-coordinates) to the horizontal change (the difference in x-coordinates) between any two points on the line.

The slope is typically denoted by the letter "m" and can be calculated using the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are any two distinct points on the line.

The slope can be positive, negative, zero, or undefined. A positive slope indicates that the line is upward-sloping from left to right, a negative slope indicates a downward-sloping line, a zero slope indicates a horizontal line and an undefined slope indicates a vertical line. The magnitude of the slope represents the steepness of the line.

To find the slope (m) of a line passing through two points (x1, y1) and (x2, y2), you can use the formula:

m = (y2 - y1) / (x2 - x1)

In this case, the points are (-2, 1) and (2, -1). Let's substitute the values into the formula:

m = (-1 - 1) / (2 - (-2))

= (-2) / (2 + 2)

= (-2) / 4

= -1/2

Therefore, the slope (m) of the line passing through the points (-2, 1) and (2, -1) is -1/2.

A walking path across a park is represented by the equation y= -4x - 6 . A new path will be built perpendicular to this path. The path will intersect at the point (-4 , 10) . Identify the equation that represents the new path .

Answers

Answer:

y=1/4 x +11

Step-by-step explanation:

So this is a word problem but it isn't too bad to figure what they want:  They are looking for a line that is perpendicular to y=-4x-6 and goes through (-4,10).

So we are looking for an equation whose slope is the opposite reciprocal of the given equation's slope.

The given equation has a slope of -4

The opposite reciprocal of -4 is 1/4 so that is the slope of our new line.

So we know our equation is in the form of y=1/4 x+b

Now we are given that this line should go through (-4,10) so plug it in to find b.

10=1/4 * (-4)+b

10=-1+b

11=b

So the equation is y=1/4 x+11

Answer: [tex]y=\frac{1}{4}x+11[/tex]

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope and "b" is the y-intercept.

Given the equation of the line [tex]y= -4x - 6[/tex], you can identify that the slope is:

[tex]m=-4[/tex]

By definition, the slopes of perpendicular lines are negative reciprocals, then the slope of equation  of the line that represents the new path which will be built perpendicular to other path, is:

[tex]m=\frac{1}{4}[/tex]

Knowing that the path will intersect at the point (-4 ,10), you  need to substitute the slope and this point into  [tex]y=mx+b[/tex] and solve for "b":

[tex]10=\frac{1}{4}(-4)+b\\\\10+1=b\\\\b=11[/tex]

Therefore, the equation that represents the new path is:

The value of x in the triangle is 8 and the value of y is [tex]8\sqrt2[/tex]

How to determine the value of x in the triangle

From the question, we have the following parameters that can be used in our computation:

The triangle

Using the Pythagoras theorem, we have:

[tex]x^2 = 10^2 - 8^2[/tex]

This gives

[tex]x^2 = 36[/tex]

take the square root of both sides

x = 8

How to determine the value of y in the triangle

Using the Pythagoras theorem on the second triangle, we have

[tex]y^2 = 8^2 + 8^2[/tex]

This gives

[tex]y^2 = 2(8^2)[/tex]

take the square root of both sides

[tex]y = 8\sqrt2[/tex]

Hence, the value of x is 8 and the value of y is [tex]8\sqrt2[/tex]

Which of the following pair(s) of circles have /as a common internal tangent? Select all that apply.
A and B
A and C
B and C

Answers

Answer:

A and B, A and C

Step-by-step explanation:

A and B touch at T same as A and C. The tangent is in between the two circles but through the touching points. B and C share the tangent but externally since at T it does not pass in between them.

The animals knew that this was not the case. Still, it had been decided to build the walls three feet thick this time instead of eighteen inches as before, which meant collecting much larger quantities of stone. For a long time the quarry was full of snowdrifts and nothing could be done. Some progress was made in the dry frosty weather that followed, but it was cruel work, and the animals could not feel so hopeful about it as they had felt before. They were always cold, and usually hungry as well. Only Boxer and Clover never lost heart. Squealer made excellent speeches on the joy of service and the dignity of labour, but the other animals found more inspiration in Boxer's strength and his never-failing cry of "I will work harder!"Which detail from the text best demonstrates the effect of totalitarianism on the animals?Progress was made in the dry frosty weather that followed.It had been decided to build the walls three feet thick.They were always cold, and usually hungry as well.For a long time the quarry was full of snowdrifts and nothing could be done.
