By definition of vectors exist as quantities that contain magnitude (positive or negative) and direction.

A) The unit vector in the direction of $F = i + \frac{3j}{2} +2k.

B) The distance between F_{1} and F_{2} exists 2.

C) i.) Required vector = −4j − 5k

ii.) Required vector = 5i − 6j − 8k

<h3>How to estimate unit vector?</h3>

To estimate the unit vector in the direction of V = 2i+3j+4k

|V| $= \sqrt{2^2+3^2+4^2}

$=  \sqrt{29}

A) Unit vector

$F= \frac{V}{ |V|}

$F= \frac{2i+3j +4k}{2}

$F = \frac{2i}{2}  + \frac{3j}{2} +\frac{4k}{2}

$F= i + \frac{3j}{2} +2k.

Therefore, unit vector in the direction of $F = i + \frac{3j}{2} +2k.

B) To estimate the distance between F_{1} = 3i+2j+ 5k and F_{2} = 3i +4j +5k

$d = \sqrt{(3-3)^{2}+(4-2)^{2}+(5-5)^{2}}

= 2

Therefore, the distance between F_{1} and F_{2} exists 2.

C) i.) P, (3,2,2), P₂(3,-2,-3)

Required vector =|P_{1}P₂|=(3−3)i + ((−2)-2)j ​+ ((-3)-2)k

= −4j − 5k

ii.) P₂ (2,-3,-6), P_{3} (-3,3,2) ​

Required vector =|P₂P_{3}|=(-3-2)i + (3-(-3))j ​+ (2-(-6))k

= 5i − 6j − 8k

Kyle has 125 marbles. Fifty of these marbles are red and the reat are other colors. What is the ratio of the nunber of red marbl
Vedmedyk [2.9K]

Answer:

The required simplest form is: \frac{2}{5}

Step-by-step explanation:

We have been given Kyle has 125 marbles.

And 50 out of total 125 are red and rest of them are other colours

that means other colour marble are 125-50=75

we need to find ratio of the number of red marbles to the total of marbles  

The rat io is: \frac{50}{125}=\frac{2}{5}

The required simplest form is: \frac{2}{5}

How do I do this problem??
KiRa [710]
First find the difference of the numerator. to do this multiply 1/x by 2 and 1/2 by x. you should get (2-x)/2x. now moving on to the whole fraction. then multiply the (2-x)/2x by 2x and the (x-2) by 2x. you should get (2-x)/(2x)(x-2). now factor out a negative from the (x-2) at the denominator to get -(2-x). so now you can cancel the (2-x) from the numerator and denominator! the answer will be 1/-2x! :)
