Answers

Answer 1

Answer:

B

Step-by-step explanation:

a² + 14a - 51 = 0 ( add 51 to both sides )

a² + 14a = 51

to complete the square

add ( half the coefficient of  the x- term )² to both sides

a² + 2(7)a + 49 = 51 + 49

(a + 7)² = 100 ( take square root of both sides )

a + 7 = ± [tex]\sqrt{100}[/tex] = ± 10 ( subtract 7 from both sides )

a = - 7 ± 10

then

a = - 7 + 10 = 3

a = - 7 - 10 = - 17

Find an equation for the number of fish P(t) after t years.

How many years will it take for the population to increase to 3050

Answers

In light of this, it will take roughly 2.25 years for the populace to reach 3050,that shows growth rate. The equation to calculate the number of fishes in a pond after t years would be equal to t = -ln (0.12125) / r

What is the growth rate?

The logistic development model can be used to calculate an equation for the growth rate of fish P(t) after t years:

Where[tex]: P(t) = K / (1 plus A e(-rt))[/tex]

[tex]r[/tex]= growth rate, where[tex]K =[/tex] carrying capacity [tex]= 6100 A =[/tex] starting population[tex]= 500[/tex]

T equals time in years

Using the given data, we can determine the increase rate:

In the first year, the quantity of fish increased from[tex]500 to 740:[/tex]

[tex]740 = 6100 / (1 + A e^(-r1))[/tex]

We arrive at [tex]A e(-r*1) = 8.24324[/tex] after solving for [tex]A e(-r).[/tex]

Given that P(t) must lie half way between A and K in order for there to be a maximal growth rate, the carrying capacity is [tex]6100:[/tex]

[tex]3050 = (6100 + 500) / 2 = 3300[/tex]

[tex]e(-rt) = 0.12125 -rt = ln = 1 + 8.24324 e(-rt) = 2(0.12125)[/tex]

[tex]t = -ln(0.12125) / r[/tex]

at[tex]t = 3300, P(t).[/tex] When we enter these numbers into the solution, we obtain:

[tex]1.84848 = A e^(-r1)[/tex]

[tex]A = 1.84848 / e^(-r1)[/tex]

We obtain the following equation for t by substituting this value of A:[tex]t = -ln(0.12125) / r t = -ln(0.12125) / ln(1.84848 / e(-r*1))[/tex]

The precise value of r is not required to provide an answer, but we can solve for it using a numerical approach like trial and error or a graphing method.

What is percentage?

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. Percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Equation:

The correct calculations to determine how much James will pay in total are:

First, we need to calculate how much 10% of $38.50 is:

10% of $38.50 = 0.1 × $38.50 = $3.85

So, James will receive a discount of $3.85.

To determine how much James will pay in total, we can use either of the following calculations:

A. James' total cost after the 10% discount would be: 38.5 - 0.9(38.5) = 38.5 - 34.65 = $3.85

B. The 10% discount on the total cost can be calculated as 0.1(38.5) = $3.85, which can be subtracted from the total cost to get James' final cost as 38.5 - 3.85 = $34.65

C. James' final cost after the 10% discount would be 1.1(38.5) = $42.35, which is not the correct answer as it does not take into account the discount.

D. James' total cost after the 10% discount would be: 0.9(38.5) = $34.65, which is the correct answer.

E. The calculation 0.1(38.5) = $3.85 represents the amount of the discount, and is not the final cost.

Therefore, options A and B are both correct. Options C, D, and E are not correct, as they do not take into account the discount that James is receiving.

What is inequality?

Inequality refers to the state of being unequal, or not having equal access to resources, opportunities, or privileges. Inequality can manifest in many different ways, including but not limited to income inequality, wealth inequality, social inequality, gender inequality, racial inequality, and educational inequality.

Inequality can be caused by a variety of factors, including systemic discrimination, unequal distribution of resources, and societal structures that favor certain groups over others. It can have a significant impact on individuals and communities, leading to disparities in health, education, economic opportunities, and overall well-being. Addressing inequality requires a multifaceted approach that involves policies and initiatives aimed at promoting equal access to resources, opportunities, and rights for all individuals.

A spinner has five equal sections marked 1-5. What is the probability of not landing on four?

Answers

Answer: 4/5

Step-by-step explanation:

Five equal sides = 5
4 is just one side, so = 1
Not landing in 4 = 4/5

Answer: 4/5 or 80%

Step-by-step explanation:

Since the spinner has five equal sections, each numbered 1 through 5, the probability of landing on any particular number is 1/5.

To find the probability of not landing on 4, we need to add up the probabilities of landing on all the other numbers and subtract that sum from 1 (since the sum of all possible outcomes must equal 1).

The probability of landing on 4 is 1/5, so the probability of not landing on 4 is:

1 - 1/5 = 4/5

Therefore, the probability of not landing on 4 is 4/5 or 0.8, which is equivalent to an 80% chance.

2.b) 47 percent of the men that cheated on their wife’s in 7 weeks have cheated many times before, how many men have cheated before?


Answers

1) Given that 1789 children visited a Taco Bell in 24 hours. We can calculate the number of students who went every hour by dividing this number by the number of hours:

[tex]1789 / 24 = 74.54\\\frac{1789}{24} = 74.54[/tex]

We get 75 students each hour, rounded up to the nearest whole number.

If 24 children shared, we can calculate the total number of children who shared by multiplying the number of hours by the number of children shared every hour:

24 x 75 = 1800

As a result, 1800 children shared.

How many men cheated on their wives in 7 weeks?

2)If 1638 men cheated on their wives in one week, multiplying by 7 gives us the number of men who cheated on their wives in seven weeks:

1638 x 7 = 11,466

As a result, 11,466 men cheated on their wives in just 7 weeks.

How many men have cheated before?

c) If 47% of the men who cheated on their spouses in 7 weeks cheated numerous times before, we can calculate the number of men who cheated previously by multiplying the total number of men who cheated by the proportion of men who cheated previously:

11,466 x 0.47 = 5,390.02

Rounding to the nearest whole number, we get 5,390 men who have cheated in the past.

The sum of one-fifth of a non-negative integer and one-third of another non-negative integer is 1. What is the maximum value of the sum of these 2 non-negative integers.

Answers

Answer: 7, and it occurs when x = 5 and y = 2

Step-by-step explanation:

1/5 x + 1/3 y = 1 (Equation 1)

x + y = ? (Equation 2)

We want to find the maximum value of x + y, so we need to maximize each of the variables x and y subject to the constraint given in Equation 1.

To solve for one of the variables, we can isolate it in terms of the other variable. Let's solve for y:

1/5 x + 1/3 y = 1

1/3 y = 1 - 1/5 x

y = 3(1 - 1/5 x)

Now we can substitute this expression for y into Equation 2:

x + y = x + 3(1 - 1/5 x)

Expanding the expression, we get:

x + y = x + 3 - 3/5 x

x + y = 3 + 2/5 x

So we can see that x + y is a linear function of x with slope 2/5 and y-intercept 3. To maximize x + y, we want to maximize x. However, x is a non-negative integer, so the maximum value of x occurs when x = 5 (since any larger value would result in a fraction in the expression for y).

Therefore, the maximum value of x + y is:

x + y = 3 + 2/5 x

x + y = 3 + 2/5 (5)

x + y = 5 + 2

x + y = 7

So the maximum value of the sum of these two non-negative integers is 7, and it occurs when x = 5 and y = 2.

Triangle PQR is translated to triangle P'Q'R'.What are the co-ordinates of Q' and R'?

Answers

Triangle PQR is translated to triangle P'Q'R'. (-3,3) and (-1,1) are the co-ordinates of Q' and R'.

The co-ordinates of Q' and R' when triangle PQR is translated to triangle P'Q'R' are (-3,3) and (-1,1), respectively.

A translation is a type of transformation where a shape is moved from one position to another.

However, the shape is not rotated, resized, or reflected in a translation.

Instead, it is moved in a straight line from one position to another.

A translation in a two-dimensional plane is specified by a vector, which specifies the distance and direction of the translation.

The co-ordinates of Q' and R' when triangle PQR is translated to triangle P'Q'R' are (-3,3) and (-1,1), respectively.

To determine these co-ordinates, we can use the following steps:

Determine the vector of the translation.

To do this, we find the difference between the corresponding vertices of the two triangles.

Here, we can take PQ as the base.

Therefore, f(11) can either be -16 or 20, depending on whether we use the recursive or explicit rule.

What is graph?

In mathematics, a graph is a visual representation of the relationship between two or more variables. It is a collection of points (or vertices) that are connected by lines or curves (called edges) to show the relationships between them. Graphs are commonly used in many different fields of study, including mathematics, science, engineering, and social sciences, to represent and analyze data, identify patterns, and make predictions.

Here,

We can observe that this is an arithmetic sequence, where each term is obtained by adding a constant difference to the previous term. To find the recursive rule, we can use the formula:

f(n) = f(n-1) + d

where f(n-1) is the previous term, d is the common difference, and f(n) is the nth term. Using the given values, we can find that the common difference is d = -6. So the recursive rule for the sequence is:

f(1) = 80

f(n) = f(n-1) - 6

To find the explicit rule, we can use the formula:

f(n) = a + (n-1)d

where a is the first term, d is the common difference, and n is the term number.

Using the first two terms, we can find that:

a = 80

d = -6

So the explicit rule for the sequence is:

f(n) = 80 - 6(n-1)

To find f(11), we can substitute n = 11 into either the recursive or explicit rule:

Using the recursive rule:

f(11) = f(10) - 6

= (f(9) - 6) - 6

= (f(8) - 12) - 6

= (f(7) - 18) - 6

= (f(6) - 24) - 6

= (f(5) - 30) - 6

= (20 - 30) - 6

= -16

Using the explicit rule:

f(11) = 80 - 6(11-1)

= 80 - 6(10)

= 20

According to the information of the graph the correct sentences are: D. Dilate ABC by a scale factor of 1/2 centered at the right angle, and E. Dilate ABC by a scale factor of 2 centered at the right angle.

How to find the correct sentences?

To show that two triangles are similar, we need to demonstrate that they have the same shape but not necessarily the same size. This can be done using similarity transformations such as dilation, rotation, and reflection. Statements A, B, and C involve rotations which would change the shape of the triangle, therefore they do not demonstrate similarity.

On the other hand, statement D suggests dilating triangle ABC by a scale factor of 1/2 centered at the right angle. This transformation will change the size of the triangle but maintain the same shape, which is a property of similar triangles. Similarly, statement E suggests dilating triangle ABC by a scale factor of 2 centered at the right angle, which again maintains the same shape but changes the size. Therefore, statements D and E demonstrate that triangle ABC and triangle LMN are similar.

Answers

The upper limit of the confidence interval for the proportion of millennials that care about immigration is 0.20.

In order to find the upper limit of the confidence interval for the proportion of millennials that care about immigration,

we first need to calculate the confidence interval using the margin of error (MOE) and sample proportion.

The formula to find the confidence interval is given by:

Confidence Interval = Sample Proportion ± Margin of Error (MOE)

Where Sample Proportion = Poll Result / 100

Let's first find the Sample Proportion of millennials that care about immigration.

Sample Proportion = Poll Result / 100= 17 / 100= 0.17

Now let's calculate the confidence interval using the MOE.

Confidence Interval = Sample Proportion ± Margin of Error (MOE)

Upper Limit of Confidence Interval = Sample Proportion + MOE= 0.17 + 0.03= 0.20

Therefore, the upper limit of the confidence interval for the proportion of millennials that care about immigration is

0.20.

Here is a point at the tip of a windmill blade. The center of teh windmill is 6 feet off the ground and the blades are 1.5 feet long. Write an equation giving the height h of the point P after the windmill blade rotates by an angle of a. Point P is currently rotated π/4 radians from the point directly to the right of the center of the windmill.

Answers

The equation that gives us the height of point P after the windmill blade rotates by an angle of θ is  h = 1.5 * sin(π/4 + θ).

How to explain the equation

Here, O is the center of the windmill, P is the point at the tip of the blade, and a is the angle through which the blade has rotated. We are given that the center of the windmill is 6 feet off the ground and the blades are 1.5 feet long.

We know that OP is the length of the blade, which is 1.5 feet. To find the angle a, we need to take into account the starting position of P. We are told that P is currently rotated π/4 radians from the point directly to the right of O. This means that if we rotate the blade by an angle of a, P will end up at an angle of π/4 + a from the point directly to the right of O.

where θ is the angle through which the blade has already rotated.

Putting it all together, we have:

h = 1.5 * sin(π/4 + θ)

This equation gives us the height of point P after the windmill blade rotates by an angle of θ.

How many lines can be formed in a cube please help tomorrow na ang deadline nito

Answers

In a cube, a total of 12 lines can be formed.

It has 8 vertices and 12 edges. In geometry, a line is a straight geometric figure that extends indefinitely in both directions. The lines in a cube are the straight lines that connect two vertices or edges of the cube. When two points are connected with a line, it creates an edge. In a cube, there are 12 edges. Each edge is shared by two faces, and the edges are the line segments that make up the sides of the cube.

Thus, the number of lines that can be formed in a cube is 12. When two or more lines meet at a point, it is called a vertex. A cube has eight vertices or corners. When a line is drawn between any two vertices of a cube, it is called a diagonal. In a cube, there are 12 diagonals. A diagonal is a straight line segment that connects two non-adjacent vertices of a polygon. So, the number of lines that can be formed in a cube is 12, which includes the 12 edges.

Find the surface area of each triangular prism.
Also don't mind my writing on the paper

Answers

The surface area of the given triangular prism is approximately 58.26 square units.

what is triangular prism?

A triangular prism is a three-dimensional geometric shape that consists of two congruent parallel triangles as its bases and three rectangular faces that connect the corresponding sides of the two triangles.

In the given question,

To find the surface area of a triangular prism, we need to add the area of all the faces of the prism. A triangular prism has two congruent triangular bases and three rectangular lateral faces.

First, let's calculate the area of the triangular bases. We can use the formula for the area of a triangle:

Area of a triangle = (1/2) * base * height

In this case, the base of the triangle is 5 and the height is 6. To find the height, we need to use the Pythagorean theorem because we are given the slant height of the triangular prism, which is the hypotenuse of the right triangle formed by the base, the height, and the slant height. The Pythagorean theorem is:

slant height² = base² + height²

Substituting the given values, we get:

6.5² = 5² + height²

42.25 = 25 + height²

height² = 17.25

height = √17.25 ≈ 4.15

Now we can calculate the area of each triangular base:

Area of a triangular base = (1/2) * base * height

Area of each triangular base = (1/2) * 5 * 4.15

Area of each triangular base ≈ 10.38

Next, we need to calculate the area of each rectangular lateral face. The length of each lateral face is the same as the base of the triangle, which is 5, and the width is the same as the width of the prism, which is 2.5. The height of each lateral face is the same as the height of the prism, which is 6. Therefore, the area of each rectangular lateral face is:

Area of a rectangular lateral face = length * width

Area of each rectangular lateral face = 5 * 2.5

Area of each rectangular lateral face = 12.5

Finally, we can find the total surface area of the prism by adding up the areas of the two triangular bases and the three rectangular lateral faces:

Total surface area = 2 * area of a triangular base + 3 * area of a rectangular lateral face

Total surface area ≈ 20.76 + 37.5

Total surface area ≈ 58.26

Therefore, the surface area of the given triangular prism is approximately 58.26 square units.
