Find the value of n for which the vectors a⃗ =(3,2)a→=(3,2) and b⃗ =(9,n)b→=(9,n) are collinear.​

Answers

Answer 1

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.

Which gives the correct values for points A, B, C, and D?

Answers

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

Which graph best represents a line with a slope of
?

Answers

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

Answers

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:

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.

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.

Answers

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.
