Answer: Last option 155°

Step-by-step explanation:

We have the components of the vectors u and v.

Then, to find the angle between them, perform the following steps:

1) Calculate the scalar product u * v

If [tex]u = 2i + \sqrt{11}j[/tex]  and [tex]v = -3i-2j[/tex]

Then, the product scalar u * v is:

[tex]u * v = (2)(-3) + (\sqrt{11})(-2)[/tex]

[tex]u * v = -6-2\sqrt{11}[/tex]

[tex]u * v = -12.633[/tex]

2) Calculation of the magnitude of both vectors.

[tex]| u | = \sqrt{(2) ^ 2 + (\sqrt{11})^2}\\\\| u | = \sqrt{4+11}\\\\| u | = \sqrt{15}[/tex]

[tex]| v | = \sqrt{(- 3) ^ 2 + (- 2) ^ 2}\\\\| v | = \sqrt{9 +4}\\\\| v | = \sqrt{13}[/tex]

3) Now that you know the product point between the two vectors and the magnitude of each, then use the following formula to find an angle

[tex]u * v = | u || v |cos(\alpha)[/tex]

[tex]-12.633 = \sqrt{15}\sqrt{13}*cos(\alpha)\\\\cos(\alpha) = \frac{-12.633}{\sqrt{15}\sqrt{13}}\\\\arcos(\frac{-12.633}{\sqrt{15}\sqrt{13}}) = \alpha\\\\\alpha =155\°[/tex]

Answer:

65°, 70°, 80°, 155°, 170°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5 ( pentagon )

sum = 180° × 3 = 540°

Sum the given angles and equate to 540

x + x - 5 + x + 10 + 2x + 15 + 2x + 30 = 540

7x + 50 = 540 ( subtract 50 from both sides )

7x = 490 ( divide both sides by 7 )

x = 70

Hence angles are

x = 70°

x - 5 = 70 - 5 = 65°

x + 10 = 7 0 + 10 = 80°

2x + 15 = (2 × 70) + 15 = 140 + 15 = 155°

2x + 30 = (2 × 70) + 30 = 140 + 30 = 170°

Answer:

1/4

Step-by-step explanation:

The same slope between line AD and line AB results from the property of similar triangles. This property states that corresponding sides are proportional, which also applies to the slopes of these sides. Hence, the slopes are equivalent.

The reason the slope of the line between point A and D is the same as the slope between points A and B derives from the concept of similar triangles in geometric math. In similar triangles, corresponding sides are proportional. This proportionality is carried over to the slopes of the lines that form these sides. Slope is defined by the change in y (vertical change) over the change in x (horizontal change). In similar triangles, these changes are proportional meaning the division, or the slope will be the same.

Consider this using Figure A1 Slope and the Algebra of straight lines where they indicate that the slope is the same all along a straight line. This also applies to the lines of similar triangles. Therefore, if triangles ADE and ABC are similar, then the slope of line AD will be the same as the slope of line AB because the ratios of their changes in y over changes in x are equal.

Step-by-step explanation:

A recursive formula allows us to calculate any term in the sequence from the previous term.

These are the terms of a geometric sequence with r being the common ratio between consecutive terms.

r = 4 ÷ - 2 = - 8 ÷ 4 = 16 ÷ - 8 = - 2

Multiplying a particular term by - 2 gives the next term in the sequence.

Hence recursive formula is

Final answer:

Using the Pythagorean theorem, we solved for the missing sides of a right triangle in three scenarios, finding b approximately as 5.20, c approximately as 7.21, and a approximately as 2.24.

Explanation:

To solve for the missing sides of a right triangle, we use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). The theorem is mathematically represented as a² + b² = c². Let's use this to solve the given problems.

For a = 3 and c = 6, to find b, we use the equation 3² + b² = 6². After calculation, b = √(36 - 9), which simplifies to b = √27 or approximately 5.20.

If a = 4 and b = 6, to find c, the equation is 4² + 6² = c². Solving for c gives us c = √(16 + 36), which is c = √52 or approximately 7.21.

For b = 2 and c = 3, to find a, we apply the formula a² + 2² = 3². This leads to a² = 9 - 4, so a = √5 or about 2.24.

It takes about 20 years

It will take approximately 13 years for the account value to reach $15,000.

To find the time it takes for the account value to reach $15,000, we used the formula for compound interest and rearranged it to solve for [tex]\(t\).[/tex] Then, we substituted the given values into the formula and calculated the time to be approximately 12.82 years. Rounding to the nearest year gives us 13 years.

To calculate the time it takes for the account value to reach $15,000 with an annual interest rate of 8.5%, we can use the formula for compound interest:

[tex]\[A = P(1 + r/n)^{nt}\][/tex]

Where:

- [tex]\(A\)[/tex] is the future value of the investment/loan, including interest.

- [tex]\(P\)[/tex] is the principal investment amount (the initial deposit or loan amount).

- [tex]\(r\)[/tex] is the annual interest rate (in decimal).

- [tex]\(n\)[/tex] is the number of times that interest is compounded per year.

- [tex]\(t\)[/tex] is the time the money is invested for, in years.

In this case, [tex]\(P = 5600\)[/tex], [tex]\(A = 15000\)[/tex], [tex]\(r = 0.085\)[/tex] (8.5% expressed as a decimal), and [tex]\(n = 1\)[/tex] (compounded annually).

We need to solve for [tex]\(t\)[/tex], so rearranging the formula:

[tex]\[t = \frac{\log(A/P)}{n \cdot \log(1 + r/n)}\][/tex]

Substituting the given values:

[tex]\[t = \frac{\log(15000/5600)}{1 \cdot \log(1 + 0.085/1)}\][/tex]

[tex]\[t[/tex] ≈ [tex]\frac{\log(2.6786)}{\log(1.085)}[/tex]

[tex]\[t[/tex] ≈ [tex]\frac{0.4285}{0.0334}[/tex]

[tex]\[t[/tex]  ≈ [tex]12.82[/tex]

To the nearest year, it will take approximately 13 years for the account value to reach $15,000.

Answer:

3 ft

Step-by-step explanation:

It is because 3 times 18 is 54 and 3 is 15 less than 18

The width of a rectangle is 3 feet .

The area can be defined as the amount of space covered by a flat surface of a particular shape. It is measured in terms of the "number of" square units (square centimeters, square inches, square feet, etc.)

According to the question

Let length of rectangle = x

The width of a rectangle is fifteen feet less than its length.

i.e,

Width of a rectangle = x - 15

Now,

Area of the rectangle = 54 square feet .

Length * Width = 54

x (x - 15 ) = 54

[tex]x^{2}[/tex] - 15x - 54 = 0

[tex]x^{2}[/tex] - (18-3)x - 54 = 0

[tex]x^{2}[/tex] - 18x + 3x - 54 = 0

x(x-18) +3(x-18) = 0

(x-18) (x+3) = 0

x= 18 , -3

length of rectangle = 18 feet

Width of a rectangle = 18 - 15

                                  = 3 feet

Hence, The width of a rectangle is 3 feet .

The solutions of the equation is 0 , π , 2π

Step-by-step explanation:

* Lets revise some identities in the trigonometry

- tan²x + 1 = sec²x

- tan²x = sec²x - 1

* Now lets solve the equation

∵ tan²x sec²x + 2sec²x - tan²x = 2

* Lets replace tan²x by sec²x - 1

∴ (sec²x - 1) sec²x + 2sec²x - (sec²x - 1) = 2 ⇒ open the brackets

∴ sec^4 x - sec²x + 2sec²x - sec²x + 1 = 2 ⇒ add the like terms

∴ sec^4 x -2sec²x + 2sec²x + 1 = 2 ⇒ cancel -2sec²x with +2sec²x

∴ sec^4 x + 1 = 2 ⇒ subtract 1 from both sides

∴ sec^4 x = 1 ⇒ take root four to both sides

∴ sec x = ± 1 ⇒ x is on the axes

∵ sec x = 1/cos x

∵ sec x = 1 , then cos x = 1

∵ sec x = -1 , then cos x = -1

∵ 0 ≤ x ≤ 2π

∵ x = cos^-1 (1)

∴ x = 0 , 2π ⇒ x is on the positive part of x-axis

∵ x = cos^-1 (-1)

∴ x = π ⇒ x is on the negative part of x-axis

- Her grandma bought her 5 more, so she then had [tex]\( x + 5 \)[/tex] Beanie Babies.

- Combining the Beanie Babies she had at the beginning, the ones she gave away, and the ones her grandma bought her, the total is 27.

- Solving the equation [tex]\( x - 8 + (x + 5) = 27 \)[/tex], we find [tex]\( x = 10 \)[/tex], the number of Beanie Babies Jane had in the beginning.

Jane had 20 Beanie Babies in the beginning.

To calculate:

1. Let's denote the number of Beanie Babies Jane had in the beginning as [tex]\( x \).[/tex]

2. She gave 8 of them to her friend, leaving her with [tex]\( x - 8 \)[/tex] Beanie Babies.

3. Her grandma bought her 5 more Beanie Babies than she had in the beginning, so she now has [tex]\( x + 5 \)[/tex] Beanie Babies.

4. Given that she now has 27 Beanie Babies, we can set up the equation:

[tex]\[ x - 8 + (x + 5) = 27 \][/tex]

Now, let's solve for [tex]\( x \):[/tex]

[tex]\[ 2x - 3 = 27 \][/tex]

[tex]\[ 2x = 30 \][/tex]

[tex]\[ x = 15 \][/tex]

However, this is the number of Beanie Babies Jane had after her grandma bought her 5 more. To find out how many she had in the beginning, we need to subtract 5 from [tex]\( x \):[/tex]

[tex]\[ x = 15 - 5 = 10 \][/tex]

So, Jane had 10 Beanie Babies in the beginning.

- Let [tex]\( x \)[/tex] be the number of Beanie Babies Jane had in the beginning.

- She gave 8 to her friend, leaving her with [tex]\( x - 8 \)[/tex] Beanie Babies.

- Her grandma bought her 5 more, so she then had [tex]\( x + 5 \)[/tex] Beanie Babies.

- Combining the Beanie Babies she had at the beginning, the ones she gave away, and the ones her grandma bought her, the total is 27.

The property of the sample standard deviation that is not accurate is 'D. Resistant to extreme data values'. The sample standard deviation is indeed sensitive to extreme data values. The other properties listed are true about the sample standard deviation.

The property of the sample standard deviation (s) that is not accurate from the given options is 'D. Resistant to extreme data values'. The sample standard deviation is sensitive to extreme values, not resistant. In other words, if there are outliers or extreme values in the data, the sample standard deviation will tend to be larger, reflecting the increased variability.

Let's quickly review the other options for clarity. 'A. Sensitive to changes in the distribution' and 'B. Calculated based on the mean' are true properties of the sample standard deviation. The standard deviation, whether for a sample or a population, measures the spread or dispersion of the data points about the mean.
