Answer:
For n=6, the given vectors will be collinear.
Step-by-step explanation:
Collinear vectors are the vectors which lie on the same line or parallel lines. In order to find if two vectors are collinear, their ratio is found. If the ratio is same for all unit vectors then the vectors are collinear.
Given
[tex]a = (a_1, a_2) = (3,2)\\b = (b_1, b_2) = (9,n)[/tex]
The ratio of first unit vectors is:
[tex]\frac{a_1}{b_1} = \frac{3}{9} = \frac{1}{3}[/tex]
In order for the vectors to be collinear the other ratio should also be 1/3
[tex]\frac{a_2}{b_2} = \frac{1}{3}[/tex]
Writing it mathematically
[tex]\frac{2}{n} = \frac{1}{3}\\2*3 = n\\n = 6[/tex]
Hence,
For n=6, the given vectors will be collinear.
6. On his fishing trip Justin takes the boat 12 km south. The fish aren't biting so he goes 4 km
west. What distance did he cover? What was his displacement?
Step-by-step explanation:
I trust that the answer is 3 because if he went 12km and bitting fish 4m which 4x3 is 12 so 3 is the answer !

Angle 6 and angle 7 are related by
Answer:the answer is 5 and 8 i guess
Step-by-step explanation: For example, angles 1 and 2 are both facing in the same direction, to the upper right. Such angles are called corresponding angles. Similarly we have angles 3 and 6, angles 4 and 7, and angles 8 and 5 as corresponding angles.
Which graph best represents a line with a slope of
?
Answer:
A. y = -2/3 + 3
Step-by-step explanation:
the line intercept the y axis at +3
and the slope is: -2/3
- i used coordinates (3,1) and (6,-1)
Answer:
y = [tex]\frac{-2}{3}x + 3[/tex]
Step-by-step explanation:
Take any two points
(x₁, y₁) = ( 3 , 1 ) & (x₂ , y₂) = (6 , -1)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]=\frac{-1-1}{6-3}\\\\=\frac{-2}{3}[/tex]
m = (-2/3) & (x₁, y₁) = ( 3 , 1 )
y - y₁ = m(x - x₁)
y - 1 = [tex]\frac{-2}{3}(x - 3)[/tex]
y - 1 = [tex]\frac{-2}{3}x - 3 *\frac{-2}{3}[/tex]
y - 1 = [tex]\frac{-2}{3}x + 2[/tex]
y = [tex]\frac{-2}{3}x + 2 + 1[/tex]
y =[tex]\frac{-2}{3}x[/tex] + 3

What is the value of g?
-5+7g=3g+ 9
Answer:
g = 7/2
Step-by-step explanation:
-5 + 7g = 3g + 9
~Add 5 to both sides
7g = 3g + 14
~Subtract 3 to both sides
4g = 14
~Divide 4 to both sides
g = 14/4 or g = 7/2

Answer:
(224)10 = (E0)16
I dont know why it wouldnt be right this is the answer...Im acually confused now
Step-by-step explanation:
(224)10 = (E0)16
Step by step solution
Step 1: Divide (224)10 successively by 16 until the quotient is 0:
224/16 = 14, remainder is 0
14/16 = 0, remainder is 14
Step 2: Read from the bottom (MSB) to top (LSB) as E0. This is the hexadecimal equivalent of decimal number 224

It rained all day on Father's Day and the temperature dropped ten and seven tenth degrees. The next day the rain
stopped and the temperature rose twelve and six tenths degrees. If the temperature at the beginning of Father's Day
was sixty five and eight tenths degrees, what was the temperature at the end of the day after Father's Day?

p. 10 of 19
Answer:
67.7
Step-by-step explanation:
Temperature at beginning of Father's Day = 65.8 degrees
Drop in temperature because of rain = 10.7 degrees
Rise in temperature after the rain the next day = 12.6 degrees
Therefore, temperature at the end of the day after the Father's Day
= Temperature at beginning of Father's Day minus Drop in temperature because of rain plus Rise in temperature after the rain the next day
= 65.8 - 10.7 + 12.6
= 67.7 degrees
NB: The answer was written as only 67.7 as requested by the questioner.

Answer:
y=1/5x + 8/5
Step-by-step explanation:
First you take the reciprocal of -5 which is -1/5.
Then you substitute the values to find the b.
1= -1/5(-3) +b
1=3/5+b
Add 3/5 to both sides
1+3/5= 5/5+3/5
b=8/5

Michaela rode her bike on 14 2/3 mile trail. She stopped every 3 1/5 miles for a drink of water . Issac and Jake estimated how many times Michaela stopped.
Answer/Step-by-step explanation:
The rail = [tex] 14\frac{2}{3} miles [/tex]
She stops after every [tex] 3\frac{1}{5}miles [/tex] for a drink.
The number of times she stopped for a drink = [tex] \frac{14\frac{2}{3}}{3\frac{1}{5}} [/tex]
Change the fractions to improper fractions
[tex] \frac{\frac{44}{3}}{\frac{16}{5}} [/tex]
Change the division operation to multiplication, and then flip the fraction on your right upside down.
[tex] \frac{44}{3} \times \frac{5}{16} [/tex]
[tex] \frac{44 \times 5}{3 \times 16} [/tex]
[tex] \frac{220}{48} = 4.58 [/tex]
If we approximate this to the nearest whole number, we would have an estimate of 5.
✅Therefore, we can conclude that Michaela stopped 5 times.
The estimate given by Issac and Jake is omitted in the question. However, the person who got an estimate of 5 is the person who made a better estimate.
Which gives the correct values for points A, B, C, and D?
Answer:
The correct answer is: A
Step-by-step explanation:
Points on a Numeric Line
The numeric line shown in the figure has four points A, B, C, and D. It's clear that each marked division of the line has a value of 1/4 units and all four points are below the reference zero, thus all are negative.
Point A is clearly on the -2 mark, thus
A=-2
Point B is one mark above A, thus it's located at:
[tex]B=-2+\frac{1}{4}=-\frac{7}{4}=-1\frac{3}{4}[/tex]
[tex]B=-1\frac{3}{4}[/tex]
Point C is one mark below -1, thus:
[tex]C=-1-\frac{1}{4}=-1\frac{1}{4}[/tex]
Finally, point D is one mark below 0:
[tex]D=-\frac{1}{4}[/tex]
The correct answer is: A
