 u = |u|(cos∝+cosβ+cosγ)

Step-by-step explanation:

Explanation

Proof:-

Given a vector  u = x₁ i + y₁j +z₁k

let O X, OY, O Z be the positive co-ordinate axes

P(x₁,y₁,z₁) be any point in the space

Let OP makes angles α,β,γ with co-ordinate axes OX , OY ,OZ .

The angle α,β,γ are known as direction angles and cosine of the angle

l =cosα , m= cosβ , n=cosγ

The perpendicular PA,PB,PC are drawn co-ordinate axes OX,OY,OZ respecctively

InΔOAP , ∠A =90° , cos∝ =[tex]\frac{x}{r}[/tex]

                                 x₁ = rcos∝

InΔOBP , ∠B =90° , cosβ =[tex]\frac{y}{r}[/tex]

                                 y₁ = rcosβ

InΔOCP , ∠C =90° , cosγ =[tex]\frac{z}{r}[/tex]

                                z₁ = rcosγ

Given   u = x₁ i + y₁j +z₁k

      |u| = [tex]\sqrt{(x_{1})^{2} +(x_{2} )^{2} +(x_{3} )^{2} }[/tex]

Therefore  u = x₁ i + y₁j +z₁k

               u = |u|(cos∝+cosβ+cosγ)

Answer:

no, I believe the correct answer would be D. (-4, 4)

Answer:

(-4, 4)

Step-by-step explanation:

Even though I don't see it explained anywhere, it seems that what looks like the coordinates of two points is really the coordinates of the first point and the translation.

That means that (-9, 6) is the original point.

(5, -2) is the translation which is a translation of 5 in x and a translation of -2 in y.

Start with (-9, 6)

Apply the translation to x and y (-9 + 5, 6 + (-2))

You get (-4, 4)

The rate of the interest for savings account is: 2%

Step-by-step explanation:

Simple interest is given by the formula

[tex]I = Prt[/tex]

Here

I is the interest,

P is the principal amount

r is the interest rate

and

t is the time period in years

Now, it is given that

P = $200

I = $8

t = 2 years

Putting the values in the formula

[tex]8 = 200 * r * 2\\8 = 400 * r\\r =\frac{8}{400}\\r = 0.02[/tex]

Converting into percentage

r = 2%

Hence,

The rate of the interest for savings account is: 2%

Step-by-step explanation:

The first equation represents the number of questions on the test. So, the second equation represents how much the questions are worth.

There are x of the 2-point questions, which have a total value of 2x points.

There are y of the 4-point questions, which have a total value of 4y points.

The test has an overall value of 150 points, so the second equation is 2x + 4y = 150.

Answer:

Option A: Axis of symmetry: x = -0.5; Vertex: (-0.5, 0.75); f(x) = x2 + x + 1

Step-by-step explanation:

1) The axis of symmetry of quadratic graph is the vertical line that divides the graph curve into two congruent halves. In this case, it is: x = -0.5

2) Vertex is the point at which the graph curve changes direction or simply coordinates of the crest or trough of the curve.

The graph given has a trough with the coordinates: x = -0.5, y = 0.75. This is (-0.5, 0.75)

3) The roots of a quadratic equation are the points where the curve crosses the x-axis. In this case, it doesn't cross and so we have imaginary roots.

Now, formula for line of symmetry is; x = -b/2a

Thus; -b/2a = -0.5 or -b/2a = -1/2

Thus, b = 1 and a = 1

Our first and second terms will now be;

x² + x

Looking at the options, the only one with x² + x as it's first 2 terms is option A.

Thus, the complete equation will be x² + x + 1

Answer:

14400 $. do u need an explanation:

so if 6000 is 100 percent

then ??? is 2 percent

to find out that you need to 6000×2 and divide by 2=120$

so you get this monthly.

in ten years you will have 14400 because

10 year=120 month

120month×120$=14400.

btw I cant speak English well. I hope it will help

Answer:

The vertices of the image will have the coordinates

A(-5, 1) → A'(2x-2, 2y-2) → A'(-12, 0)

B(-4, 3) → B'(2x-2, 2y-2) → B'(-10, 4)

C(1, 2) → C'(2x-2, 2y-2) → C'(0, 2)

D(-3, 0) → D'(2x-2, 2y-2) → D'(-8, -2)

Step-by-step explanation:

Note: You missed to mention the vertices of a quadrilateral ABCD. So, I am assuming the following vertices. It would anyways clear your concept.

Let us suppose

We know that the rule of the dilation with the center of dilation at (2,2) by a scale factor of 2 is:

Therefore, the vertices of the image will have the coordinates

A(-5, 1) → A'(2x-2, 2y-2) → A'(-12, 0)

B(-4, 3) → B'(2x-2, 2y-2) → B'(-10, 4)

C(1, 2) → C'(2x-2, 2y-2) → C'(0, 2)

Step-by-step explanation:

Answer:

y=2, x=1

Step-by-step explanation:

3x-6y=12(x2)

5x-2y=10(x6)

Eliminate y

6x-12y=12

30x-12y=60

-24x =-48

divide both sides by -24

-24x/-24=-48/-24

y=2

to get our x

3x-6(2)=12

3x-12=12

3x=12+12

3x=24(divide both sides by 3)

x=1

Answer:

395,500

Step-by-step explanation:

The computation is shown below:

Supplier to retailer = 320,000

Vat tax = 13%

Retailer spent for transportation = 10,000

local tax = 5,000

Profit = 15,000

Now based on the above information

the customer would pay the amount with 13% vat is

= (320,000 + 10,000 + 5,000 + 15,000) + 13% of total

= 350,000 + 13% of 350,000

= 350,000 + 45,500

= 395,500

Answer:

Y(n)=15n+40

Step-by-step explanation:

Lets represent the number of bean stalks she plant by n and

the yield by Y.

It says in the question that when she plants 2 stalks, each plant yields 70 ounces of beans. When she plants 8 stalks, each plant yields 160 ounces of beans.

Which means 2 stalks correspond to 70 ounces and 8 stalks corresponds to 160 ounces we could write the data Mathematically like:

(2 , 70) and (8 , 160) are our coordinates where the x-axis would be n the number of beans stalks planted  and y-axis would be Y the yield in ounces.

So we have two coordinates and to find the linear relationship we must find out the slope/gradient(m) of the linear function by the formula of slope:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{160-70}{8-2} \\\\m=\frac{90}{6} \\\\m=15[/tex]

so we plug in one of the coordinates and our slope in the point-slope formula :

[tex]y-y_1=m(x-x_1)[/tex]

where,

[tex](x_1,y_1)\ represent\ the\ coordinate\ (2,70)[/tex]

so plugging in the coordinate and the value of m we get:

[tex]y-y_1=m(x-x_1)\\y-70=15(x-2)\\y-70=15x-30\\y=15x-30+70\\y=15x+40\\[/tex]

so our the answer is the last option

Y(n)=15n+40

here x corresponds to n and y corresponds to Y(n)

Answer:

[tex]350 * D \geq 1400[/tex]

[tex]D\ge 4[/tex]

This means that the family must travel for at least 4 days.

Step-by-step explanation:

Given

[tex]Rate = 350\ miles\ daily[/tex]

[tex]Distance = 1400\ miles\ (atleast)[/tex]

Required

Determine and solve the inequality

The number of days is represented with D

So:

On any D number of days, the family would have covered a distance of 350 * D miles

If the total distance is at least 1400, then the inequality is:

[tex]350 * D \geq 1400[/tex]

[The term "At least" is used to represent greater than or equal to]

[tex]350 * D \geq 1400[/tex]

Divide through by 350

[tex]\frac{350 * D}{350} \ge \frac{1400}{350}[/tex]

[tex]D \ge \frac{1400}{350}[/tex]

[tex]D\ge 4[/tex]

This means that the family must travel for at least 4 days.

Answer: The expected value is $0.32

Step-by-step explanation:

The expected value can be calculated as:

EV = ∑xₙ*pₙ

Where:

xₙ is the n-th event.

pₙ is the probability of the n-th event.

First, let's see the events in this situation and the probability of each event.

Lossing $1.

This happens when you roll all different numbers.

To calculate the number of combinations where you roll all different values, we first need to count the number of possible options for each roll, this is:

First dice: you have 6 options

Second dice: You have 5 options, because we remove the option that was rolled in the first dice.

Third dice: You have 4 options, because we removed the two outcomes showed in the two previous rolls.

Then the number of combinations is:

c = 6*5*4 = 120.

And the total number of combinations for rolling 3 dice is equal to the product between the number of outcomes for each dice, each dice has 6 possible outcomes, then the total number of outcomes is:

C = 6*6*6 = 216

The probability of rolling all different numbers will be equal to the quotient between the number of combinations where you roll all different values and the total number of combinations:

P₁ = 120/216 = 0.56

In the other case, where you roll at least two equal outcomes, you win $2.

The probability for this case will be the complement of the previous one, then the probability can be calculated as:

P₂ = 1 - P₁ = 1 - 0.56 = 0.44

Then the expected value will be:

EV = -$1*0.56 + $2*0.44 =  $0.32

The expected value is $0.32

Answer:

0.5532

Step-by-step explanation:

We have these events

WF = Wins the first game

LF = lose the first game

WS = Wins the second game

LS = lose the second game

Then

Prob(WF) = 0.6

Prob(LF) = 0.4

Prob(WS|WF) = 0.35

Prob(WS|LF) = 0.65

1. If he wins the second game, the probability that he lost the first =

P(Lf|WS)

= 0.4x0.65/0.4x0.65+0.6x0.35

= 0.21/0.47

= 0.5532

0.5532 is the probability that he lost the first game given that he wins the second
