How much miles is a light year

Mathematics
1 answer:
skelet666 [1.2K]3 years ago
8 0

1 light-year = roughly  5,874,601,700,000 miles.  (rounded)

To work it out, take the speed of light, and change units a few times:

          (186,282.397 miles/second)
times
          (86,400 second/day)
times
          (365 day/year)

    =   (186,282.397 x 86,400 x 365)  mile/year .

You can whip that out on your calculator in no time.

The expression 16x2 + 4x + 125 represents the height, in feet, of a rock, x seconds after being thrown from a cliff. What does t
xeze [42]

The motion of the rock thrown from the cliff which goes downwards due to

the gravitational force, is a free fall motion.

  • 125 represents; <u>A. The initial height of the rock</u>.

Reasons:

The given function that represents the height of the of the rock in feet <em>x</em> seconds after being thrown is; f(x) = 16·x² + 4·x + 125

At the initial height before being thrown from the cliff, we have;

The time, x = 0

The initial height is therefore;

The initial height f(0) = 16 × (0)² + 4 × (0) + 125 = 125

125 represents <u>A. The initial height of the rock</u>

What expression is equivalent to -x + 5 - 13 + 12x
zvonat [6]

Answer:

11x - 8

Step-by-step explanation:

If you have x- + 5 - 13 + 12x, all we are doing is combining like terms. First, 5 - 13 = -8. Then, -x + 12x is the same as doing 12x - x. That gives us 11x. The answer would be 11x - 8 when you put -8 and 11x together in the expression.

Can someone help me?
Phoenix [80]

Answer:

m∠R = 112°

m∠S = 112°

m∠T = 68°

Step-by-step explanation:

Quadrilateral QRST is a cyclic quadrilateral.

A <u>cyclic quadrilateral</u> is a quadrilateral drawn inside a circle where every vertex touches the circumference of the circle.  

The <u>opposite angles</u> in a cyclic quadrilateral sum to 180°.

⇒ m∠Q + m∠S = 180°

⇒ m∠R + m∠T = 180°

Given:

  • m∠Q = 68°
  • m∠R = (3x + 40)°
  • m∠T = (5x - 52)°

<u>Measure of angle Q</u>

⇒ m∠Q + m∠S = 180°

⇒ 68° + m∠S = 180°

⇒ m∠S = 180° - 68°

⇒ m∠S = 112°

<u>Measure of angles R and T</u>

⇒ m∠R + m∠T = 180°

⇒ (3x + 40)° + (5x - 52)° = 180°

⇒ )8x -12)° = 180°

⇒ 8x° = 192°

⇒ x = 24

Substituting the found value of x into the expressions for angles R and T:

⇒ m∠R = (3(24) + 40)°

⇒ m∠R = 112°

⇒ m∠T = (5x - 52)°

⇒ m∠T = 68°

Find the slope.....<br>​
Luden [163]

Answer:

slope = 1/2

Step-by-step explanation:

slope = y2-y1 / x2-x1

1 - -2 / 4 - -2 = 3/6 = 1/2

or think of it this way. for every 1 step up you take 2 steps to the right to stay on the line. 1/2
