Answer:
-1/2 or
Step-by-step explanation:
to find the slope, use the formula
(y₁ - y₂)/(x₁ - x₂)
(2 - -3)/(-4 - 6)
(2 + 3)/(- 4 - 6)
5/-10
1/-2
-1/2
The initial age of 10 years and the spaceship speed of 0.60•c, gives the Andrea's age at the end of the trip as 18 years.
<h3>How can Andrea's new age be calculated?</h3>The time dilation using the Lorentz transformation formula is presented as follows;
From the question, we have;
The spaceship's speed, <em>v</em> = 0.6•c
∆t = Rest frame, Courtney's time, change = 10 years
Therefore;
The time that elapses as measured by Andrea = 8 years
Andrea's age, <em>A</em>, at the end of the trip is therefore;
A = 10 years + 8 years = 18 years
