Step-by-step explanation:

To find the approximate annual growth rate of the stock, we can use the formula for compound annual growth rate (CAGR):

CAGR = (Ending value / Beginning value)^(1/n) - 1

Where n is the number of years.

In this case, the beginning value is $2545.30, the ending value is $4152.57 and the number of years is 6.

So, CAGR = (4152.57 / 2545.30)^(1/6) - 1

The CAGR is approximately 26.8% which is the answer 2.

Similarity is the mathematical property of triangles. Two triangles are called similar if they fulfil wither of the properties: Angle Angle, wherein two angles should be congruent; Side Angle Side, wherein two sides are similar to each other and the angles congruent to each other; and Side Side Side, wherein three sides are similar to each other in ratio.

The triangle ABC and triangle EDF are similar.

The first property is angle,

∠BAC = ∠EDF = 65°

The second property is also angle.

∠ABC = ∠DEF = 48° (∠DEF = 180 - 65 - 67)

Thus, the three angles are same or congruent.

The AA property of similarity makes the two triangles ABC and DEF similar. The option 1 is correct.

The perimeter of the figure, is represented by the expression, 14x + 16.

The perimeter of a figure is the total length of the outer boundaries of the figure. It is the sum of all the sides of the figure.

The perimeter is used to determine the size of a figure and can be calculated by adding the lengths of all the sides together.

Therefore:

Perimeter of the figure = 4(2x - 1) + 2(3x + 10)

To simplify the expression 4(2x - 1) + 2(3x + 10), we can distribute the constants (4 and 2) to the expressions inside the parentheses.

First, we'll simplify 4(2x - 1) using the distributive property:

4(2x - 1) = 4(2x) + 4(-1) = 8x - 4

Next, we'll simplify 2(3x + 10) using the distributive property:

2(3x + 10) = 2(3x) + 2(10) = 6x + 20

Now we can add the two simplified expressions together:

8x - 4 + 6x + 20 = 14x + 16

So, the simplified form of 4(2x - 1) + 2(3x + 10) is 14x + 16.

Answer:

Step-by-step explanation:

Let x be the amount invested in the 6% account.

Since he invested twice as much in the lower-yielding account, the amount invested in the 10% account is 2x.

We know that the annual interest is $3080 dollars, and the interest is calculated on the invested amount at each rate.

The interest in the 6% account is (6/100) * x = 3/50 * x

The interest in the 10% account is (10/100) * 2x = 1/10 * 2x

The total annual interest is 3/50x + 1/102x = 3/50x + 1/5x = (3+1)/5x = 4/5x

Therefore, we can write the equation:

4/5*x = 3080

To find x, we can divide both sides by 4/5:

x = 3080*5/4

x = $2310

So, the man invested $2310 in the 6% account and $2310*2 = $4620 in the 10% account.

Answer:

To find out how many batches of cookies the factory made, we need to divide the total amount of flour used (7 1/2 bags) by the amount of flour used per batch (3 3/4 bags).

We can start by converting 7 1/2 bags of flour to a mixed number: 7 1/2 bags = 7 + 1/2 = 7.5 bags

Next, we can convert 3 3/4 bags of flour to a mixed number: 3 3/4 = 3 + 3/4 = 3.75 bags

Then, we can divide the total amount of flour used by the amount of flour used per batch:

7.5 bags / 3.75 bags/batch = 2 batches

Therefore, the factory made 2 batches of cookies yesterday

Considering the context of the question and the percentage analysis, it is concluded that a 38.64% charge has been hiked in the price of the ticket and if the extra $50 is charged for the baggage fee the hike is 61.36%.

A percentage is a number or ratio indicated as a fraction of 100. To get the percentage of any number, such number will be divided by the number of the whole and multiplied by 100. Hence, the percentage means, a part per hundred

In this case, Cari is searching online for airline tickets. Two weeks ago, the cost to fly from Hartford to Orlando was $220. Now the cost is $305

Hike in price = 305 - 220 = 85

Hike % = 85/220 * 100% = 38.64%

When the extra charge is $50 for extra baggage, the total price = is $355

Hike in price = 355 - 220 = 135

Hike % = 135/220 *100% = 61.36%

Answer: An equation of the line passing through point P(-6, 4) that is perpendicular to y + 8 = 2(x - 14) is:

y = -4x + 20

Step-by-step explanation:

The given equation is in slope-intercept form y = mx + b, where m is the slope of the line and b is the y-intercept. The slope of the line is 2, which means the line has a slope of 2 and is inclined at an angle of tan^-1(2).

To find an equation of a line that is perpendicular to this line, we need to find the negative reciprocal of the slope, which is -1/2. This means the slope of the line passing through point P(-6, 4) that is perpendicular to y + 8 = 2(x - 14) is -1/2.

Now we can use the point-slope form of a linear equation to find the equation of the line passing through point P(-6, 4) and having a slope of -1/2. The point-slope form of a linear equation is:

y - y1 = m(x - x1)

Where (x1, y1) is the given point, and m is the slope of the line. So by substituting the values we get:

y - 4 = -1/2(x + 6)

Which can be written as:

y = -1/2x + 4

So the equation of the line passing through point P(-6, 4) that is perpendicular to y + 8 = 2(x - 14) is:

y = -1/2x + 4

Graphing the equations can confirm that the lines are perpendicular as the slope of the first line is 2 and the slope of the second line is -1/2, the product of these slopes is -1 which means they are perpendicular to each other.

Using the given information, the value of the number is 12

From the given information, we have that
"7 more than twice a number is 5 less than three times the same number"

Let the number be x

7 more than twice a number means

2x + 7

5 less than three times the number is

3x - 5

Thus,

The equation becomes

2x + 7 = 3x - 5

Now, solve for x

Answer:The most general form of a polynomial function of degree n that has real coefficients is:

f(x) = a_nx^n + a_{n-1}x^{n-1} + ... + a_2x^2 + a_1x + a_0

where a_n, a_{n-1}, ..., a_1, a_0 are real numbers, and a_n is not equal to zero.

The number of distinct roots of a polynomial function of degree n can be determined using the fundamental theorem of algebra, which states that a polynomial function of degree n has exactly n roots, counting multiplicities. This means that a polynomial function of degree n can have n distinct roots, n-1 distinct roots, or any integer value in between, depending on the multiplicities of the roots.

Using the factor theorem, it is possible to determine the number of distinct roots of a polynomial function by factoring it into its irreducible factors. If the polynomial function is fully factored, the number of distinct roots is equal to the number of irreducible factors.

However, the nature of the roots (real or complex) and constraints imposed by the discriminant are also important to consider. The discriminant of a polynomial function is the value of the expression b^2-4ac, where a, b, and c are the coefficients of the polynomial function in the form f(x) = ax^2+bx+c. The discriminant determines the nature of the roots of the polynomial function. If the discriminant is positive, the roots are real and distinct. If the discriminant is zero, the roots are real and repeated. If the discriminant is negative, the roots are complex and non-real.

So, the most general form of a polynomial function of degree n that has real coefficients, can be determined by the form of the polynomial, the number of distinct roots by the fundamental theorem of algebra, by factoring the polynomial into its irreducible factors and the nature of the roots is determined by the discriminant.

Logic can be defined as the study of rational thinking. It contains both formal and informal logic. Deductively sound inferences or logical truths are studied in formal logic. It is a formal science that examines the topic-neutral ways in which conclusions flow from premises. As opposed to informal logic, which is connected to argumentation theory, critical thinking, and informal fallacies, formal logic is a branch of logic.

Philosophy, mathematics, computer science, and linguistics are just a few of the disciplines where logic is crucial. A set of premises and a conclusion make up an argument, which is the subject of logic. Arguments can be proven right or wrong. If the premises of an argument support the conclusion, then it is valid.

Answer:

In order to find when the two trains will meet up, we can use the concept of relative speed. The relative speed of two trains is the sum of their individual speeds.

In this case, the relative speed is 30 + 50 = 80km/h

Since we know that the distance between London and Bristol is 100km, we can divide the distance by the relative speed to find the time it takes for the two trains to meet up:

So, the two trains will meet up in 1.25 hours
