The distance light travels in one year is known as a light-year. A light-year is equal to 5.87 × 1012 miles. The closest Earth ever gets to Jupiter is 3.65 × 108 miles. What is a correct representation of the number of years it will take light to travel from Earth to Jupiter at this distance? Check all that apply.

Answers

Answer:

The answer is A and C

Step-by-step explanation:

The required distance is 6.21 × 10⁻⁵ light-years it will take light to travel from Earth to Jupiter at this distance. which is the correct answer would be an option (C)

What is the distance?

Distance is defined as the product of speed and time.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

We have been given that the distance light travels in one year is known as a light year.

one light-year = 5.87 × 10¹² miles.

A light year is the length of time it takes light to travel one distance.

Since the closest that Earth ever gets to Jupiter is 3.65 × 10⁸ miles.

So 3.65 × 10⁸ miles =  1/(5.87 × 10¹² )×(3.65 × 10⁸) light years

⇒ 6.21 × 10⁻⁵  light years

Therefore, the required distance is 6.21 × 10⁻⁵ light-years it will take light to travel from Earth to Jupiter at this distance.

The constant of proportionality Or the value of Euros is 3/2 times of the value of a dollar.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

To obtain the constant of proportionality we'll need to determine at least two coordinate points from the graph they are, (1, 3/2) and (2, 3).

Let, no. of dollars be 'x' and no. of euros be 'y'.

So, y = kx.

3/2 = k.

Answer:

γ = [tex]\lim_{n \to \infty}\sum_{k=1}^n (\frac{1}{k}-ln(n) )[/tex]

or

γ = -∞

Step-by-step explanation:

Let's solve what's inside the limit first.

We see that we need to take the sum of the entire thing. Since it is multivariable and we are given 1 variable, it stays the same.

Now we move on to the limit.

We replace n in the summative with infinity.

The natural log of infinity is infinity.

1 minus infinity would be negative infinity.

The sum of negative infinity of k = 1 is negative infinity.

So the limit as n approaches infinity would be negative infinity.

If we were to simplify this mathematically, it would just be the same equation.

The width of the fountain in Luke's drawing from the example is 2 cm. What is the width of the fountain in Isabella's scale drawing?

Answers

Answer:

2.5cm

Step-by-step explanation:

If Luke's scale for his drawing is 5m to 2cm, then it means that every 2cm on Luke's scale drawing represents 5m in real life. So since the width of the fountain is 2cm, the actual fountain width must be 5m. As established in the example, Isabella's scale factor from drawing to real life is 6/3=2, which means any measurement in cm on her drawing can simply be multiplied by 2 to obtain the real life measurement in m. So, to convert back the other way, from real-life to drawing, we just need to divide the value by 2 instead of multiply. So, if the real life value is 5m, then the width on her scale drawing should be 5/2 = 2.5cm.

Hope this helped!

Using proportions, it is found that:

The width of the fountain in Isabella's scale drawing is of 1.6 cm.

-----------------------------------

This question is solved by proportions, using a rule of three.

Isabella's scale is of 6m to 3cm, that is, 2m to 1cm.Luke' scale is of 5 m to 2 cm, that is, 2.5m to 1 cm.From this, it can be taken that a drawing of 250cm in Luke's scale is of 200 cm in Isabella's scale.What is the width of Isabella's drawing, considering that Luke's width is 2 cm?

200 cm - 250 cm

x cm - 2 cm

Applying cross multiplication:

[tex]250x = 400[/tex]

[tex]x = \frac{400}{250}[/tex]

[tex]x = 1.6[/tex]

The width of the fountain in Isabella's scale drawing is of 1.6 cm.
