Answer:

Hey there,

The answer is below!!

Step-by-step explanation:

Knowing that those vectors start at the point (0,0) we can "think" them as lines.

As you may know, two lines are parallel if the slope is the same, then we can find the "slope" of the vectors and see if it is the same.

A) the vectors are: (√3, 1) and (-√3, -1)

You may remember that the way to find the slope of a line that passes through the points (x1, y1) and (x2, y2) is s = (y2 - y1)/(x2 - x1)

Because we know that our vectors also pass through the point (0,0)

then the slopes are:

(√3, 1) -----> s = (1/√3)

(-√3, -1)----> s = (-1/-√3) =  (1/√3)

The slope is the same, so the vectors are parallel.

Part B:

The vectors are: (2, 3) and (-3, -2)

the slopes are:

(2, 3) -----> s = 3/2

(-3, -2)----> s = -2/-3 = 2/3

the slopes are different, so the vectors are not parallel.

Answer:

=-f +12g

Step-by-step explanation:

Answer:

-1f+12g

Step-by-step explanation:

Answer:

Answer= 50%

Step-by-step explanation:

7k=7000g

7000÷350=20

20x75p=1500p

1500=£15

£15 is £5 more than £10. £5 is half of £10 meaning its an extra 50%

(Could Be Wrong Tho, My Apologies If It Is!)

Answer:

The slope is -2.

Step-by-step explanation:

1) The equation for a slope is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].

2) Plug in x and y values into the equation. I plugged in (3,0) and (8,-10) into the equation.

3) You end up with: [tex]\frac{-10 -0}{8-3}[/tex], which simplifies down to [tex]\frac{-10}{5}[/tex], which equals -2.

Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day, and good luck on your assignment. :)

Answer:

3.712 x 10^8

Step-by-step explanation:

use the commutative property to reorder the terms

(5.8x 6.4) x (10^5 x 10^2)

multiply 5.8 x 6.4 = 37.12

add 5+2=8

37.12 x 10^7

write the number in scientific notation

3.712 x 10^8

that'sur answer

Answer: 5.8 x 10^5 =

              6.4 x 10^2 =

Step-by-step explanation:

There is 5   10's because number of exponents are 5

so you multiply 5.8 by 10 10 10 10 10

The other is 6.4

multiply that by 10 10

But you can't multiply by all of that with one constant

So you answer the first one 10 x 10 x 10 x 10 x 10 = 100000

the other is 100

So now you multiply 5.8 by 100000

And multiply 6.4 by 100

Answer:

Answer:

The 3rd from the choices is correct.

Answer: 200

Step-by-step explanation: You can use the Pythagorean theorem for this question. First, you must find a and b. You can do this by finding the distance between North and South, and East and West. For this specific equation, you'd use 200 North - 30 North to get 170 miles on the y-axis. Then, you'd do 50 East + 100 West to get 150 kilometers distance on the x-axis. Now that you have 170 and 150, you can begin the equation

170^2 + 150^2 = c^2

28900 + 22500 = c^2

51400 = c^2

√51400 = √c^2

~226 = c

They are approximately 226 kilometers apart, and 226 is closest to 200, which is B.

Answer:

12

Step-by-step explanation:

We know that 1/3 of a pizza is cheese meaning that 6 pizzas are made of cheese and there are only two leaving the rest pepperoni and 12 are left if we subtract the cheese pizzas minus the 18 pizzas we have 12 which are pepperoni.

Answer:

Answer is 6 because line are parallel

Answer:

x = 111º

Step-by-step explanation:

In a heptagon, (A polygon with 7 sides, and therefore 7 angles), the sum of the interior angles is always 900º (just like the sum of all interior angle in a quadrilateral is always 360º). So you can add up all of the interior angles, and subtract them from 900º.

900º - (158º + 120º + 126º + 125º + 121º + 139º) = 111º

Answer:

Equation : y = 4.50D + 40

Number of pairs = 16

Step-by-step explanation:

It is given that:

Per day wage of Roger = $40

Commission on per pair of shoes = $4.50

Daily goal = $112

Number of pairs of shoes = D

Total earning = y

y = 4.50D + 40

112 = 4.50D + 40

4.50D = 112 - 40

4.50D = 72

Dividing both sides by 4.50

[tex]\frac{4.50D}{4.50}=\frac{72}{4.50}\\D = 16 \\[/tex]

Therefore,

Equation : y = 4.50D + 40

Number of pairs = 16

Step-by-step explanation:

y= mx + b
