Questions & Step-by-Step Solutions

The eccentricity of an ellipse is defined as e = c/a. If a = 10 and c = 6, what is the eccentricity?
  • Step 1: Identify the values given in the problem. We have a = 10 and c = 6.
  • Step 2: Write down the formula for eccentricity, which is e = c/a.
  • Step 3: Substitute the values of c and a into the formula. This means we replace c with 6 and a with 10.
  • Step 4: Calculate the value of e by dividing c by a. So, we do 6 divided by 10.
  • Step 5: Simplify the fraction 6/10. This gives us 0.6.
