For the following vectors, (a) find the dot product v•w ; (b) find the angle between v and w , (c) state whether the vectors are parallel, octagonal, or neither. V=-3i-4j, w=6i+8j
A- v•w
B-the angle between v and w is theta ^•?
C- the vectors v and w are?

Answers

A) v • w = (-3)(6) + (-4)(8) = -18 - 32 = -50
B) The angle between vectors v and w can be found using the formula: cos(theta) = (v • w) / (||v|| ||w||), where ||v|| and ||w|| are the magnitudes of vectors v and w respectively.

First, we need to find ||v|| and ||w||:

||v|| = sqrt((-3)^2 + (-4)^2) = 5
||w|| = sqrt((6)^2 + (8)^2) = 10

Now, we can substitute in the values to get:

cos(theta) = (-50) / (5 * 10) = -1
theta = arccos(-1) = pi radians or 180 degrees.

Therefore, the angle between vectors v and w is 180 degrees.

C) Two vectors are parallel if their directions are the same, which can be determined by comparing their unit vectors.

The unit vector of v is:

v_hat = v / ||v|| = (-3/5)i + (-4/5)j

The unit vector of w is:

w_hat = w / ||w|| = (6/10)i + (8/10)j = (3/5)i + (4/5)j

We can see that the unit vectors are in opposite directions, which means that the vectors are anti-parallel or opposite. Therefore, the vectors v and w are neither parallel nor orthogonal.

Therefore , the solution of the given problem of function comes out to be  (g - f)(-1) = 29.

What exactly does function mean?

The math lesson covers an extensive variety of subjects, including geometry, integers, one's divisions, construction, and both real and imagined geographic places. A work covers the connections between various variable that all work together to produce the same result. A utility is made up of a variety of distinctive components that cooperate to create distinct results for each input.

Here,

We must first evaluate g(-1) and f(-1) before subtracting the results to obtain (g - f)(-1).

We possess

=> g(x) = 5x + 18

=>  g(-1) = 5(-1) + 18 = 13

=>  f(x) = x² - 17

=>  f(-1) = (-1)² - 17 = -16

Therefore:

=>  (g - f)(-1) = g(-1) - f(-1) = 13 - (-16) = 29

So, we have the following representation

y = 3x - 9

x = (y + 9)/3

How should she correct it?

Answers

The given sequence is

\(-3,4,11,18\)

As you can observe, this sequence as a difference of 7, that is, each new term is the sum of the previous term with seven.

Arithmetic sequences are defined by

\(a_n=a_1+(n-1)d\)

Where, in this case, we have

\(\begin{gathered} a_1=-3 \\ d=7 \\ n=58 \end{gathered}\)

Replacing these values, we have

\(a_{58}=-3+(58-1)7=-3+(57)7=-3+399=396\)

The 58th term is 396.

(a) The reason why Amanda is wrong is she used 18 as the first term which is not correct because 18 is the fourth term of the sequence.

(b) To correct her mistake, she just needs to use -3 as the first term in the formula.

The measure of ZPQR is approximately 113°. This can be solved usiing the concept of geometry.

What is Geometry?

One of the first areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects. A geometer is a mathematician who specializes in geometry.

Therefore, to find the measure of ZPQR, we would follow the following steps:

Let x= measure of <PQR

Hence, the measure of <PQR

296 = x/360 x 3.14 x 2 x 150

The statement is true that the number that has 9 as a factor also has 3 as a factor.

What is the associative property of addition?

Suppose you've got 3 numbers a, b, and c.

Then, we have  (a+b) + c = a + (b + c)

This property is called an associative property and it is called because we can associate b with a, or b with c without altering the value of the addition.

We have been given the phrase "Any number that has 9 as a factor also has 3 as a factor"

3 x 3 = 9.

Here using the associative property of multiplication;

a x b = b x a = ab

So, we can see that any number that has 9 as a factor also has 3 as a factor.

18  = 9 x 2

Rate of the boat in still water:
Rate of the current:

Answers

9514 1404 393

Answer:

boat: 35 km/hcurrent: 6 km/h

Step-by-step explanation:

Let b and c represent the rates of the boat and current, respectively. Then the upstream rate is ...

  speed = distance/time

  b -c = (116 km)/(4 h) = 29 km/h

  b +c = (164 km)/(4 h) = 41 km/h

Adding these equations gives ...

  2b = 70 km/h

  b = 35 km/h

Substituting into the first equation, we have ...

  35 -c = 29

  c = 6

Rate of the boat: 35 km/h.

Rate of the current: 6 km/h

The Lucas sequence is like the Fibonacci sequence except that the starting numbers are 2 and 1 instead of 1 and 0. What are the first ten terms of the Lucas sequence?

Answers

The first ten terms of the Lucas sequence are 2, 1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199, 322, 521, 843.

What is Lucas sequence?

The Lucas sequence or Lucas series are an integer sequence named after the mathematician francois Edouard Lucas, which are similar to the Fibonacci numbers, each Lucas number is defined to be the sum of its two immediate previous terms, thereby forming a fibonacci integer sequence.

Now, the sequence of first 10 numbers of Fibonacci series are-

0, 1, 1 ,2, 3, 5, 8, 13, 21, 34

which are defined as set of integers that starts with zero, followed by a one,then by another one and then by series of steadily increasing numbers,The sequence follow the rule that each number is equal to the sum of preceding two numbers.

And the sequence of Lucas sequence is -

2, 1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199, 322, 521, 843.

which is definedas  the sum of its two immediate previous terms.

The Lucas number may thus be defined as follows;

Ln =    \(\left \{ {{2} ; if n= 0 \atop {1}; if n = 1} \right.\)

Here we can see that Lucas series starts with 2 and 1 whereas Fibonacci series starts with 0 and 1.

Hence,The first ten terms of the Lucas sequence are 2, 1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199, 322, 521, 843.

During a sale at the local department store, you buy three sweatshirts and two pairs of sweatpants for$85.50. Later, COACH Ike returned to the same store and bought three sweatshirts and four pairs ofsweatpants for $123. What is the sale price of each sweatshirt and each pair of sweatpants? i need help please

Answers

We are going to formulate a system of equations to represent this situation and the we are going to solve it.

Let x represent the sale price of one sweatshirt.

Let y represent the sale price of one pair of sweatpants.

3x + 2y = 85.5 (Equation 1)

3x + 4y = 123 (Equation 2)

Using the elimination method to solve the system, we have:

c-3x - 4y =- 123

----------------------

0 - 2y = -37.5 ( Subtracting the equation 2 from the equation 1)

y= 18.75 ( Dividing by 2 on both sides of the equation)

Replacing y=18.75 in the equation 1 to solve for x, we have:

3x + 2(18.75) = 85.5

3x + 37.5 = 85.5 (Multiplying)

3x = 48 (Subtracting 37.5 from both sides of the equation)

x= 16 (Dividing by 3 on both sides of the equation)

The answers are:

The sale price of one sweatshirt is $16.

The sale price of one pair of sweatpants is $18.75.
