So, anything in the first quadrant would be positive (for both values of x and y).

That means E and F are the correct choices, since both (4, 8) and (2, 2) are positive and would be found in the first quadrant.

There are two twins. One twin wants to explore the planet near Proxima Centauri and leaves on a spaceship traveling at 90% of th

miskamm [114]

Answer:

4.7 years

Step-by-step explanation:

Distance of planet from Earth = 1.3 parsec

We know that 1 parsec = 3.26 light years

And a light year is the distance traveled by light in time period of 1 year.

So, Distance of planet from Earth = 1.3 $\times$ 3.26 = 4.24 light years

Given that, the person travels at a speed equal to 90% of the light speed.

To travel to the planet from Earth, Light takes 4.24 years.

To travel the distance $D$ , at a speed $s$ light takes time of 4.24 years.

To travel the distance $D$ , at a speed $0.90s$ , the person takes time:

$\dfrac{4.24}{0.90} = \bold{4.7\ years}$

So, the twin on Earth ages by 4.7 years.

Suppose you are going to graph the data in the table below. What data should be represented on each axis and what should the inc

Greeley [361]

Independent variable on x-axis (value you can choose) dependent variable on y-axis (corresponding value for the value you have chosen) You can the hours and the distance traveled is a function of those hours. also, I'd go in increments of 5. More accurate than increments of 15. The answer is D! 
Hope this helps!

What is the measure of each interior angle of a regular octagon?

Anuta_ua [19.1K]

Answer:

I think the answer is Option D, 135 degrees.

Since the angles of all of the octagon combined is 1080, divide that by 8 to get 135 which means that all 8 angles are 135 degrees.
