The methods that astronomers have used to detect extrasolar planets are:
- Measuring the Doppler shift of the light from a star to see how the star "wobbles" due to the gravity of the planet
- Directly observing the extrasolar planet around its parent star
What are the methods that astronomers have used to detect extrasolar planets ?
The astronomers used the Directly observing the extrasolar planet around its parent star for them to be able to detect extrasolar planets.
They also used Measuring the Doppler shift of the light from a star to see how they scatters.
CHECK THE COMPLETE QUESTION BELOW:

Answer:
1.30288 × 10³ g
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass= density x volume
mass = 13.6 × 95.8 = 1302.88

An example of Lesson 6.1 identifying and representing functions is Complete the table. write a rule as an algebraic expression for the output, then complete the last row of the table using the rule.
<h3>What are functions?</h3>
In mathematics, a function is known to be the link or the relation that exist between a set of inputs and a set of other outputs.
The answer to the table is in the image attached. The solution is given below:
Note that the number of pages per minute:
= 1/2 = 0.5
Total cost = 0.5x
And x is the number of minutes.
x = 0.5x
30 = 0.5(30)
= 15

Hi!
So for this problem you need to know how that there are 8,760 hours in a year. If we're trying to find how many deaths there were per hour, you'd need to divide 33,300 by 8760 to find out.
33,300/8760=3.80136986301
This means there were roughly 3.8 deaths per hour.
Hope this helps :)
