Find the solutions to x2 = 27.
O A. x = +3,5
B. x = +39
O C. x = +9.12
D. X = +9.5

Answer:

A

Step-by-step explanation:

Given

x² = 27 ( take the square root of both sides )

x = ± [tex]\sqrt{27}[/tex]

  = ± [tex]\sqrt{9(3)}[/tex]

  = ± [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex]

A car accelerates from rest to 25 miles per hour in 3.0 seconds. What was the car's
acceleration?

Answers

Answer:

The car's acceleration was 3.73 metre per second square = 3.73m/s²

Step-by-step explanation:

The car accelerated from rest.

initial velocity (u) = 0m/s

final velocity (v) = 25miles/hr = 11.2m/s

time (t) = 3s

a = ?

v = u+at

a = (v-u)/t

a = (11.2 - 0) / 3

a = 11.2/3

a = 3.73

a = 3.73m/s²

The NYC subway system has a total of 850 miles of train tracks, and a NYC subway train has an average speed of 17.4 mph. If you laid all 850 miles of track end-to-end in one big circle, how much time would it take to ride a NYC subway train around the entire circumference of that circle?

Answers

Answer:48.85 hr

Step-by-step explanation:

Given

The length of the train track is [tex]L=850\ miles[/tex]

the average speed of the train is [tex]v_{avg}=850\ mph[/tex]

If this track is laid on to a big circle, then the length is equivalent to the circumference

time is taken to cover the circumference is given by

[tex]\Rightarrow t=\dfrac{L}{v}\\\\\Rightarrow t=\dfrac{850}{17.4}=48.85\ hr[/tex]

Answer:

n=1

Step-by-step explanation:

to solve this you put 19 on the opposite side and subtract 19 fron 21 because subtraction is the opposite of addition and then you get 2 and then divide 2 by 2 to get 1 so n=1. Yo can check it by doing 2*1=2 then 2+19 =21 so it is the correct answer.

Step-by-step explanation:

The equation for finding the area of a hexagon with a side length is

insert [tex]6\sqrt{3}[/tex]

and you are left with 162\sqrt{3}

Answer:

[tex] \displaystyle E)\: 162 \sqrt{3} [/tex]

Step-by-step explanation:

we are given a side a polygon

and said to figure out the area

recall the formula of regular polygon

[tex] \displaystyle \: \frac{ {na}^{2} }{4} \cot \left( \frac{ {180}^{ \circ} }{n} \right) [/tex]

where a represents the length of a side

and n represents the number of sides

the given shape has 6 sides

and has a length of [tex]\displaystyle 6\sqrt{3}[/tex]

so our n is 6 and a is 6√3

substitute the value of n and a:

[tex] \displaystyle \: \frac{ {6 \cdot \:( 6 \sqrt{3} })^{2} }{4} \cot \left( \frac{ {180}^{ \circ} }{6} \right) [/tex]

reduce fraction:

[tex] \displaystyle \: \frac{ {6 \cdot \:( 6 \sqrt{3} })^{2} }{4} \cot \left( \frac{ { \cancel{180}^{ \circ}} ^{ {30}^{ \circ} } }{ \cancel{6 \: } } \right) [/tex]

[tex] \displaystyle \: \frac{6 \cdot \: (6 \sqrt{ {3} } {)}^{2} }{4} \cot( {30}^{ \circ} ) [/tex]

simplify square:

[tex] \displaystyle \: \frac{6 \cdot \: 36 \cdot \: 3 }{4} \cot( {30}^{ \circ} ) [/tex]

reduce fraction:

[tex] \displaystyle \: \frac{6 \cdot \: \cancel{36} \: ^{9} \cdot \: 3 }{ \cancel{ 4 \: } } \cot( {30}^{ \circ} ) [/tex]

[tex] \displaystyle \: 6 \cdot \: 9 \cdot \: 3 \cot( {30}^{ \circ} ) [/tex]

simplify multiplication:

[tex] \displaystyle \: 162\cot( {30}^{ \circ} ) [/tex]

recall unit circle:

[tex] \displaystyle \: 162 \sqrt{3} [/tex]

hence, our answer is E
