The dot product a . b is -22

What is the dot product

The dot product, also known as scalar product or inner product, is a binary operation that takes two vectors and returns a scalar (single-valued) quantity. The dot product of two vectors is equal to the product of the magnitude (length) of the vectors and the cosine of the angle between them.

Given two vectors, A and B, the dot product is defined as:

A ∙ B = |A| * |B| * cos(θ)

where |A| and |B| are the magnitudes of vectors A and B, and θ is the angle between them.

a = <3, -2>

b = <-2, 8>

a . b = (3 * -2) + (-2 * 8)

a . b = -6 + - 16

a . b = -22

Describe Triangle?

A triangle is a two-dimensional geometric shape that has three sides and three angles. It is the simplest polygon and is a fundamental building block in many areas of mathematics and science.

The three sides of a triangle can have different lengths and can be of different types, such as equilateral, isosceles, or scalene. An equilateral triangle has three sides of equal length, while an isosceles triangle has two sides of equal length and a third side of a different length. A scalene triangle has all three sides of different lengths.

In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. Thus, we have:

sin(IHJ) = IJ/IH

Taking the sine of both sides and substituting the given values, we get:

sin(23°) = x/2

Multiplying both sides by 2, we have:

x = 2*sin(23°)

Using a calculator, we get:

x ≈ 0.83

Therefore, the value of x is approximately 0.8 cm when rounded to the nearest tenth.

O A. b(a)=+7
B. b(a)--7
O C. b(a)- +5
OD. b(a)-2-5

Answers

Note that the function takes the trapezoid's area as input and returns as output the length of the other base is A(x)/7-5=x.

What is the area of a Trapezoid?

Recall that the function for the trapezoid area is:

A(x)=(B+b)*h/2

where

B and b are the bases and

h is the height.

Thus, given a height of 14 and one base length of 5 with the length of its other base

With the given data: h=14 B and b =5 and x (it may vary which one is bigger)

So that function becomes:

A(x)=(5+x) * 14/2

A(x)=(5+x)*7

So if you want the inverse function, you have to operate to find x:

A(x)/7=5+x

A(x)/7-5=x

Reeta has spent 2/7 of her salary on car repair work. She has 15. 000 rupees left with her. What is her salary?

Answers

As per unitary method, Reeta's salary is 21,000 rupees.

The unitary method is a technique of solving problems by assuming a unit value and then finding out the required value in terms of that unit.

In this problem, we can assume Reeta's salary to be the unit value and then find out how much she spent on car repair work and how much money she has left using this unit value.

Let's assume Reeta's salary to be x rupees. Now, according to the problem, she has spent 2/7 of her salary on car repair work. So, the amount of money she spent on car repair work can be calculated as:

2/7 * x

Using the unitary method, we can now find out how much money she has left with her. We know that she has 15,000 rupees left. So, we can set up the following proportion:

2/7 * x = x - 15,000

Simplifying this equation, we get:

2x = 7(x - 15,000)

2x = 7x - 105,000

5x = 105,000

x = 21,000

Find the measures of each interior angles of a regular polygon having 15 sides

Answers

The measure of each interior angle of a regular polygon having 15 sides is equal to option B: 156°.

A polygon is an enclosed figure composed of more than three straight lines. To find the measure of each interior angle of a regular polygon having n sides, we would first find the total sum of interior angles of this polygon. The formula is:

(n-2) × 180°

= (15-2) × 180°

= 13 × 180°

= 2340°

We, here, found that the sum of all interior angles of a regular polygon having 15 sides is equivalent to 2340°. Now, to find the measure of each angle, we can divide this sum by the number of sides as:

2340/15 = 156°.

Therefore, the measure of each angle of a regular polygon having 15 sides is equivalent to 156°.

______________________________________________________________

B. Dena wants to make a birdhouse with the leftover wood. She needs 105 3/5 centimeters of wood for the birdhouse. Write and evaluate an expression to determine how much more wood will be needed.
______________________________________________________________

Answers

A. To find the total length of wood left over, we need to add the lengths of all 5 pieces of wood. We can represent each piece of wood with a fraction and then add all the fractions. The total length of wood can be represented as:

12.7 + 26 3/10 + 15 4/5 + 21 1/4 + 19.2 = (12.7 + 26 + 15 + 21 + 19.2) + (3/10 + 4/5 + 1/4)

To simplify the expression, we can convert the mixed numbers (26 3/10 and 21 1/4) to improper fractions and convert the fractional part of decimals (3/10 and 4/5) to decimals:

12.7 + 26 3/10 = 12.7 + 26.3

15 4/5 = 15 + 0.8

21 1/4 = 21 + 0.25

3/10 = 0.3

4/5 = 0.8

So the expression becomes:

12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2 = (12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2) + 0.3 + 0.8 = 104.45

Therefore, the total length of wood left over is 104.45 centimeters.

B. To determine how much more wood will be needed for the birdhouse, we can subtract the total length of wood left over from the required length:

105 3/5 - 104.45 = (105 + 0.6) - 104.45 = 105.6 - 104.45 = 1.15

Therefore, 1.15 centimeters more of wood is needed to make the birdhouse.

You’ve saved $45, which is 70% of the amount you want to save. What is the total amount you want to save? (round to nearest cent) * *

Answers

Rounding this to the nearest cent, the total amount that was wanted to be saved is $64.29.

To solve this problem, we can set up a proportion using the given information. Let x be the total amount that was wanted to be saved.

We know that the amount saved ($45) is 70% of the total amount that was wanted to be saved. Therefore, we can write:

45 = 0.7x

To solve for x, we can divide both sides by 0.7:

x = 45 ÷ 0.7

x = 64.28571429

The answer to the problem is $64.29, rounded to the nearest cent. This means that the total amount that was wanted to be saved was $64.29, and 70% of this amount is equal to the amount that was actually saved ($45). To check our work, we can multiply 64.29 by 0.7 to see if it equals 45. When we do this, we get:

64.29 x 0.7 = 45.003, which rounds to $45, so our answer is correct.

Does the set of odd integers have the density property? Explain.​

Answers

It should be noted that the set of odd integers has the density property. The density property states that for every subset of the real numbers that contains an infinite number of points, the interior of that subset contains a non-empty open interval. This is true

How to explain the information

The set of odd integers is a countable subset of the real numbers, meaning that it can be put into a one-to-one correspondence with the natural numbers. However, even though it is countable, it still has an infinite number of points.

Since the set of odd integers contains an infinite number of points, it must contain a non-empty open interval in its interior. To see this, consider the interval (2n-1, 2n+1) for any positive integer n. This interval contains the odd integer 2n and its endpoints are both odd integers, so it is completely contained in the set of odd integers.

Therefore, the set of odd integers has the density property and is a dense subset of the real numbers.

The difference between a two-digit number and the reverse of the number is 18. What could the original number be if the reversed number is also a two-digit number? List all possibilities.


pls answer by sunday february 12, 12:00 p.m. , pacific standard time!

Answers

Answer:

27, 36

Explanation:

To find the possible two-digit numbers that meet the criteria, we can use algebra. Let x be the original two-digit number, and let y be the reverse of x. Then, we have:

x - y = 18

We can also write y in terms of x:

y = x % 10 * 10 + x / 10

Substituting the expression for y into the equation x - y = 18, we get:

x - (x % 10 * 10 + x / 10) = 18

Expanding and simplifying the right side of the equation, we get:

9x = 180 + 10

Dividing both sides of the equation by 9, we get:

x = 20

Since x must be a two-digit number, 20 is not a valid solution. However, we can check the two numbers that are close to 20, which are 18 and 21.

For x = 18, we have y = 81, which is a two-digit number, so 18 is a valid solution.

For x = 21, we have y = 12, which is a two-digit number, so 21 is also a valid solution.

Therefore, the possible two-digit numbers that meet the criteria are 27 and 36.

Now, let us say that Luke had X marbles then Andre will have X-200 marble and Shemai will have X/2 marbles.

Now, all the marbles combined will be equal to 1400, so, the simple algebraic relation will be,

X + X-200 +X/2 = 1400

X+X+X/2 = 1600

For h = 1 day, the average rate of change of R(t) is 90 dollars/day. This can be calculated by dividing the difference in output of the function at t and t+h, i.e., 30t3+30(t+1)3 = 1080, by the length of the period, h = 1 day.

For h = 0.1 day, the average rate of change of R(t) is 900 dollars/day. This is calculated by dividing the difference in output of the function at t and t+h, i.e., 30t3+30(t+0.1)3 = 9, by the length of the period, h = 0.1 day.

For h = 0.01 day, the average rate of change of R(t) is 9000 dollars/day. This is calculated by dividing the difference in output of the function at t and t+h, i.e., 30t3+30(t+0.01)3 = 0.9, by the length of the period, h = 0.01 day.

The instantaneous rate of change of R(t) at time t is the limit of the average rate of change of R(t) as h approaches 0. In this case, the instantaneous rate of change of R(t) at time t = 1 is R'(1) = 9000 dollars/day.

solve the right triangle by completing the table below :) help asap

Answers

The missing sides of the two right triangles are B ≈ 75.5, b ≈ 10.7 and a ≈ 6.9.

How to find the missing sides of a system formed by two similar right triangles

In this problem we find two similar right triangles. Two triangles are similar when they have congruent angles and sides that are not congruent but proportional. Sides in right triangles are related each other by means of Pythagorean theorem:

r² = x² + y²

Where:

r - Hypotenusex, y - Legs

According to the statement, we need to use the following relationships:

B = √(C² - A²)

a / A = b / B = c / C

If we know that A = 49, C = 90 and c = 12.7, then the lengths of missing sides are:

B = √(90² - 49²)

B = √5699  (approx. 75.5)

b = B × (c / C)

b = √5699 × (12.7 / 90)

b = 127√5699 / 900 (approx. 10.7)

a = A × (c / C)

a = 49 × (12.7 / 90)

a = 6233 / 900 (approx. 6.9)
