find the direction cosines and direction angles of the vector. (give the direction angles correct to the nearest tenth of a degree.)

Answers

Answer 1

The direction cosines and direction angles will be - [tex]\frac{x}{r},\frac{y}{r},\frac{z}{r}[/tex] and

cos⁻¹([tex]\frac{x}{r}[/tex]), cos⁻¹([tex]\frac{y}{r}[/tex]),cos⁻¹([tex]\frac{z}{r}[/tex]) respectively.

The direction cosines of a specified vector, m = xi + yj + zk, are the cosines of the angles it makes well with x, y, and z axes.

The direction cosines of m are cos a, cos b, and cos c  in the x, y, and z axes, respectively, if a forms the angles a,b and c (which are the direction angles) with the x, y, and z axes, respectively.

Let us consider equation as =  [tex]xi + yj +zk[/tex]

vector of the equation will be - (x,y,z)

r = length of vector = [tex]\sqrt{x^{2} +y^{2} +z^{2} }[/tex]

The direction cosines will be -

[tex]\frac{x}{r},\frac{y}{r},\frac{z}{r}[/tex]

angles will be - cos⁻¹([tex]\frac{x}{r}[/tex]), cos⁻¹([tex]\frac{y}{r}[/tex]),cos⁻¹([tex]\frac{z}{r}[/tex])

Let us consider an example,

If we have vector as (1,2,3)

= i + 2j + 3k

= r = [tex]\sqrt{1^{2} +2^{2} +3^{2} }[/tex]

= [tex]\sqrt{14}[/tex]

Direction cosines will be -

[tex]\frac{1}{\sqrt{14} } , \frac{2}{\sqrt{14} }, \frac{3}{\sqrt{14} }[/tex]

Angles will be -

cos⁻¹([tex]\frac{1}{\sqrt{14} }[/tex]), cos⁻¹([tex]\frac{2}{\sqrt{14} }[/tex]),cos⁻¹([tex]\frac{3}{\sqrt{14} }[/tex])

PLEASE HELP ASAP. I am stuck

a. how far is the delivery from the starting point in miles

b. which vehicle would take longer to finish the delivery, the car or the truck​

and how much longer would the faster vehicle be than the slower one.


Please explain why

Answers

Part A

Answer: 360 miles

Reason:

The graph shows the highest point occurs when y = 360. After this point, the truck turns around to go back to the starting point (the warehouse perhaps).

In other words, the truck starts at y = 0 when it's at the warehouse. It travels 360 miles to reach the customer, which is represented as the highest point of the V shaped curve. This process takes 6 hours.

Then another 6 hours elapses when the truck drives back to the warehouse. We assume the same route is used, and similar traffic conditions occur for each leg of the trip.

============================================================

Part B

Answer: The truck

Reason:

The graph shows that the truck takes 12 hours to get back to the warehouse. We look at the x intercept because this is when the distance from the start is back to y = 0 again.

Now we need to find out how long the car takes on its trip.

We'll plug in y = 0 into the car's equation and solve for x.

y = -72|x-5| + 360

0 = -72|x-5| + 360

72|x-5| = 360

|x-5| = 360/72

|x-5| = 5

x-5 = ± 5

x-5 = 5 or x-5 = -5

x = 5+5 or x = -5+5

x = 10 or x = 0

x = 0 or x = 10

This tells us that the car is at the warehouse when x = 0 and when x = 10.

Therefore, the car takes 10 hours to do a round trip, and it's the faster vehicle.

Which function has a larger maximum?

Answers

Answer:

The function from the above scenario that has a larger maximum is function 1.

What is the function about?

Note that the first function is;

x = - b/ 2 a = 6 /8 = 3/4

f ( 3/4 ) = - 4 * 9/16 + 6 * 3/4 + 3

= - 9 /4 + 18 / 4 + 3

= 2.75 + 3 = 5.25

y max = 5.25

The second Function is:

y max = 2

Therefore we can see that the first function has a larger term that is ( 5.25 > 2 ).

there were twice as many four-door cars as two-door cars in the parking lot. there were 36 cars in the lot. how many had four doors? how many had two doors?

Answers

the number of two door cars in the parking lot is 12 and the number of four door cars in the parking lot are 24.

We are given that the number of four door cars in a parking lot is equal to twice the two door cars.

Let the two door cars be x

Four door cars = 2 x

Also, we are given that total cars = 36

So, we get the equation:

x + 2 x = 36

3 x = 36

x = 36 / 3

x = 12

Two door cars = x = 12

Four door cars = 2 x = 2 ( 12) = 24

Therefore, we get that, the number of two door cars in the parking lot is 12 and the number of four door cars in the parking lot are 24.

Cailyn is packing 1-centimeter cubes into a prism. What is the volume of the prism.

Answers

If Cailyn is packing 1-centimeter cubes in a prism of same dimensions and in the same manner as as shown in the figure attached, where Joe is packing 1-centimeter cubes into the prism, then the volume of the prism is 210 cm³.

As per the question statement, Cailyn is packing 1-centimeter cubes in a prism of same dimensions and in the same manner as as shown in the figure attached, where Joe is packing 1-centimeter cubes into the prism.

We are required to calculate the volume of the prism.

As we can see from the reference diagram attached  hereby, our prism can hold a 7 cubes along its length, 6 cubes along its width and 5 cubes along its height.

And since the constituent cubes are all identical and of volume 1 cm³, it means that all the dimensions (length, width and height) of each of the constituent cubes is 1cm.

Therefore, length of our prism [tex]=(7*1)=7[/tex] cm,

Width of our prism [tex]=(6*1)=6[/tex] cm,

And, height of our prism [tex]=(5*1)=5[/tex] cm.

Therefore, volume of our prism = (length * width * height)

                                                    [tex]=(7*6*5)\\=(42*5)\\=210[/tex]

From 2008 to 2010, the cost of houses rose by 60%. if the cost of houses rose by 40% from 2008 to 2009, to the nearest percent, how much did the cost rise from 2009 to 2010?

Answers

The increase in cost from 2009 to 2010 is 14.28%

In order to solve this question we will be taking the following example:

Let the cost of the house in 2008  = $1000

Increase in cost from 2008 to 2010 = 60%

Cost of the house in 2010 = 1000 + 60%*1000 = $1600

Increase in cost from 2008 to 2009 = 40%

Cost of the house in 2009 = 1000 + 40%*1000 = $1400

Increase in cost from 2009 to 2010 = 1600 - 1400 = $200

Percentage increase in cost from 2009 to 2010 = (Increase in cost/Cost of the house in 2009)*100

=(200/1400)*100

= 14.28% or 14%

Therefore, there has been an increase of 14.28% in the cost of houses from 2009 to 2010

Anthony drew a pentagon whose each side measures 6inches

Whereas, Carol drew a hexagon whose each side measures 5inches

The formula to calculate the Perimeter of the Pentagon is: 5*a

and, the formula to calculate the Perimeter of the Hexagon is: 6*a

In the given formulas, 'a' represents the measure of the side for both the Pentagon & Hexagon.

Calculating, Perimeter of Pentagon P1 = 5 * a, where a = 6 inches

                         => P1 = 5*6  => P1 = 30inch

Calculating, Perimeter of Hexagon P2 = 6*a, where a = 5 inches

                         => P2 = 6*5 => P2 = 30inch

From the given graph, we have that:

In function notation, we have that:

g(-5) = 2, g(-3) = 0, g(0) = -3, g(3) = -6, g(5) = -8.

How to get the ordered pairs from the graph of a function?

To get the ordered pairs from the graph of a function, we have to:

Get the x-coordinate, that is, the value of the point on the horizontal axis.Get the y-coordinate, that is, the value of the point on the vertical axis.

An ordered pair has the following notation: (x,y).

Hence, from the points on the graph, the ordered pairs are given as follows:

(-5,2), (-3,0), (0,-3), (3,-6), (5, -8).

How to write the ordered pairs in the table?

To write the table from each ordered pair (x,y), we have that y = g(x), hence:

x = -5, g(x) = 2.x = -3, g(x) = 0.x = 0, g(x) = -3.x = 3, g(x) = -6.x = 5, g(x) = -8.

How to write the function notation?

We take the g(x) points from the table, replacing x by it's numeric value, hence:

g(-5) = 2, g(-3) = 0, g(0) = -3, g(3) = -6, g(5) = -8.
