anbody know what this x means

The second vector that's perpendicular to the line we want (call it L) is missing; I'll denote it by ⟨a, b, c⟩.

The cross product of ⟨1, 1, 0⟩ and ⟨a, b, c⟩ is perpendicular to both of these vectors. The direction vector of L will be parallel to this cross product.

Compute the cross product.

⟨1, 1, 0⟩ × ⟨a, b, c⟩ = ⟨1•c - 0•b, 0•a - 1•c, 1•b - 1•a⟩ = ⟨c, -c, b - a⟩

Then the vector equation of L is

L(t) = ⟨c, -c, b - a⟩ t + ⟨-3, 3, -1⟩

As parametric equations, we write

x(t) = ct - 3

y(t) = -ct + 3

z(t) = (b - a) t - 1

Eliminating the parameter above, we get

x + y = (ct - 3) + (-ct + 3) = 0   ⇒   x = -y

and substituting

x = ct - 3   ⇒   t = (x + 3)/c

into z(t), we get

z = (b - a) (x + 3)/c - 1   ⇒   x = c (z + 1)/(b - a) - 3

As symmetric equations, then, we write

x = -y = c (z + 1)/(b - a) - 3

The linear equation doesn't have a solution.

The linear equation given is illustrated as: 4x-(2x-1) = x+5+x-6

This will be solved thus:

4x - 2x + 1 = x+5+x-6

4x - 2x + 1 = 2x - 1.

2x + 1 = 2x - 1

Collect like terms

2x - 2x = -1 - 1

0 = -2

This illustrates that the equation doesn't have a solution.

The value of ∠ F L H  is 3x-6°

∠FLG and ∠FLH are adjacent angles with L being the common vertex  and both the angles form the ∠HLG

As ∠FLG is given as 14x + 5° and  ∠ H L G is given as 17 x − 1 °

We need to find the value of ∠ F L H

We can write that ∠FLG +∠FLH = ∠ H L G

by putting the values given

14 x + 5 ° + ∠ F L H  = 17 x − 1 °

∠ F L H = 17x-1 - (14x + 50

Here we got a linear equation in one variable and by solving the equation we will get the value of ∠ F L H

∠ F L H = 17x - 1 - 14x -5

∠ F L H  = 3x-6

Hence, the value of ∠ F L H  is 3x-6°

Step-by-step explanation: 48 is the highest mileages

Answer:

x2 + 8x + 15

Step-by-step explanation:

First - take the first terms of the brackets (so, x and x) and multiply them together: for this example that gives x2.

Outside - take the two outermost terms of the brackets (x and 5) and multiply them together: for this example that gives 5x.

Inside - take the two innermost terms of the brackets (3 and x) and multiply them together: for this example that gives 3x.

Some people may draw lines between terms when doing this (as seen in the diagram above) leaving you with a “crab claw” around the brackets.

Write down everything you have worked out as one long expression:

x2 + 5x + 3x + 15

Then, we will simplify this expression by grouping any “like” terms (this just means adding together any bits with x where they have the same power).

This leaves us with our final answer, which is:           

x2 + 8x + 15

The equation is 8x + 4.79= 60.39 and the value is x is $6.95

Nabhitha pays a total of $60.39 for the cookies and onions

She pays a total of $4.79 for the cookies

She buys 8 bags of onions that each costs the same amount of money

The equation used to find the value of x is written as

8x + 4.79= 60.39

Collect the like terms

8x= 60.39 - 4.79

8x= 55.6

Divide both sides by the coefficient of x which is 8

8x/8 = 55.6/8

x= 6.95

Hence the price of each bag of onions is $6.95

Cost of pen = 20x  when x< 10

                              and

                      =10x when x>10

Let the number of pens bought be x.

So the total pen cost is 20x when the number of the pen is less than 10.

Now let's take that the number of pens bought is more than 10

So the pen will cost a 50% discount  

    50% of 20x

  = 20/100 × 20x

  = 10x

So the cost of the pen will be 10x when the number of the pen is greater than 10.

From this, we get to know that

Cost of pen = 20x when x<10

                              and

The probability of drawing a red card, placing it back in the deck, and drawing another red card is 1/4.

According to the given question.

Total number of cards in a deck is 52.

As we know that total number of red cards in a well shuffled deck is 26.

Since, Eric first draws a red card, places it back in the deck, shuffles the deck, and then draws another card. Which means there is a replacement of cards.

So, the probability of drawing the first card is red = 26/52 = 1/2

And the probability of drawing the another card is red = 26/52 = 1/2

Therefore,

The probability of drawing a red card, placing it back in the deck, and drawing another red card

= 1/2  × 1/2

= 1/4

Hence, the probability of drawing a red card, placing it back in the deck, and drawing another red card is 1/4.

Answer:non terminating

Step-by-step explanation:

Answer:

a. 3 units

Step-by-step explanation:

The length of BC can be found in 3 main steps, namely the formation of equations, solving for x and substitution.

Let's rewrite the given lengths:

AB= 4x +1 -----(1)

BC= 2x -7 -----(2)

AC= 24 -----(3)

Form an equation which relates the 3 lengths:

Given that B is between A and C,

AC= AB +BC -----(4)

Substituting equations (1) to (3) to equation (4):

24= 4x +1 +2x -7

Simplify:

24= 6x -6

Add 6 to both sides:

6x= 24 +6

6x= 30

Divide both sides by 6:

x= 5

Substitute x= 5 into (2):

BC

= 2x -7

x < 0

Answer : x is less than or equal to 0

First, the direction of the number line in the graph is the negative number side, so it has to be 0 or less.

If it is less than 0, the dot that starts at the point 0 must have a hollowed out part in the middle. If it is 0 or less, the dot that starts at the point 0 is completely filled with no hollowed middle part.

Since the dot is completely blacked out, the answer is the second option.

The ratio of blue hats to red hats IS 3:2 , the ratio of the blue hats all hats is 3:5 and If the store purchased 45 hats, 27 hats were blue

The ratio of blue hats to red hats is 9:6, which can be simplified to 3:2

Therefore the ratio of blue hats to red hats is 3: 2

The total number of hats is the summation of blue hats and red hats = 9+6= 15

So, The ratio of blue hats to all hats is 9:15, which can be simplified to 3:5

Therefore the ratio of blue hats to red hats is 3: 5

If the store purchased 45 hats, and we need to find out the number of blue hats

We have to assume the number of blue hats be x

Then the ratio becomes x: 45::3:5

3.1.1.  A(-4, 0)   B(0, -2)   E(4, 0)

3.1.2.  k = -16

3.1.3.  (-∞, ∞)

3.1.4.  [-16, ∞)

3.1.5.  [-6, 4]

Step-by-step explanation:

Given functions:

[tex]\begin{cases}f(x)=x^2+k\\g(x)=-2x+8\\h(x)=\dfrac{6}{x-2}+1\end{cases}[/tex]

Points A and B are the x-intercept and y-intercept of function h(x).

Point E is the x-intercept of function g(x).

The x-intercept of function h(x) is when h(x) = 0:

[tex]\begin{aligned}h(x) & = 0\\\implies \dfrac{6}{x-2}+1 & = 0\\\dfrac{6}{x-2} & = -1\\6 & = -1(x-2)\\6 & = -x+2\\4 & = -x\\x & = -4\end{aligned}[/tex]

Therefore, the coordinates of point A are (-4, 0).

The y-intercept of function h(x) is when x = 0:

[tex]\begin{aligned}h(x) & = \dfrac{6}{x-2}+1\\\implies h(0) & = \dfrac{6}{0-2}+1\\ & = -3+1\\& = -2\end{aligned}[/tex]

Therefore, the coordinates of point B are (0, -2).

The x-intercept of function g(x) is when g(x) = 0:

[tex]\begin{aligned}g(x) & = 0\\\implies -2x+8 & = 0\\-2x & = -8\\x & = 4\end{aligned}[/tex]

Therefore, the coordinates of point E are (4, 0).

As function f(x) passes through point C (-6, 20), substitute the point into the equation of the function to find the value of k:

[tex]\begin{aligned}f(-6) & = 20\\\implies (-6)^2 + k & = 20\\36 + k & = 20\\k & = 20 - 36\\k & = -16\end{aligned}[/tex]

Hence, proving that the value of k is -16.

The domain is the set of all possible input values (x-values).

The domain of function f(x) is unrestricted, therefore its domain is:

The range is the set of all possible output values (y-values).

The range of function f(x) is restricted, since the minimum point of the parabola is at (0, -16).  Therefore its range is:

[tex]\begin{aligned}g(x) - f(x) & \geq 0\\\implies g(x) &\geq 0+f(x)\\ \implies g(x) & \geq f(x)\end{aligned}[/tex]

Therefore, find the interval for which g(x) is greater than or equal to f(x).

From inspection of the given graph this is between points C and E:

The circumference of the Canadian $1 coin is 83.21 mm

For given question,

We have been given the Canadian $1 coin has a diameter of 26.5 mm.

We need to find the circumference of the coin.

We know that circumference of a circle of radius r is,

c = 2πr

The Canadian $1 coin has a diameter of 26.5 mm.

So, the radius of the coin would be,

r = 26.5 /2

r = 13.25

Using the formula of circumference, the circumference of the coin would be,

⇒ c = 2πr

⇒ c = 2 × π × r

⇒ c = 2 × 3.14 × 13.25

⇒ c = 83.21 mm

What is the amount (to the nearest cent) in the account at the end of three years if the interest rate is 2%? $1,350.68

Step-by-step explanation:

DATA:

Deposits (at beginning of year):

Year 1 = $500

Year 2 = $200

Year 3 = $600

growth factor: z = 1 + r

interest rate is 2% so replace r with 2%. Growth factor equation is now:

z = 1 + 2%

z = 1.02

Year 1 account balance end of year = account balance + growth factor

= $500 + 1.02

= $ 510 account balance at end year 1

Year 2 account balance end of year = (previous year ending balance + current year deposit) * growth factor

= ($510 + $200) * 1.02

= $724.20

Year 3 account balance end of year = (previous year ending balance + current year deposit) * growth factor

= ($724.20 + $600) * 1.02
