1. ## Vectors

Determine if the line through A(1, 2, 3) and B(4, 8, -3) and the line through C(3, 5, 3) and D(0, 2, 4) intersect. Having a hard time figuring out this problem.
2. ## Chemistry

A weak acid with an initial pH of 3.2 was titrated with a strong base. 15 mL of 0.1 M NaOH was added to the acid to reach the equivalence point at a pH of 8.6. What would you expect the approximate pH of the analyte to be after the first 5 mL of 0.1 M NaOH
3. ## Chemistry

What is the pH of a 0.25 M acetic acid solution if the Ka of acetic acid is 1.8 x 10-5? 2.67 0.60 5.34 11.33 I got A, 2.67. I think this is correct as well since acetic acid is a weaker acid and the ph # would make sense.

8.Which of the following best describes changes in the population of Washington over the last 200 years? Cultural diversity has increased due to migration and immigration. A.The Native American population has not changed locations. B.Immigration from

Describe four measures that can be taken to improve or develop human resources in ghana

1. ## Vectors

Steve, I still don't understand how those values for t and s are the same, when I do substitute the numbers in, it gives me different values.
2. ## Vectors

Also, I think you've got the wrong answer posted. I don't know how you got -1/3, but when I use both equations for the third equation, I get different results.
3. ## Vectors

Does my answer have to be expressed as a point, or just what the parameters are that satisfy the condition that they make both lines intersect?

thank you so muchhhhh!!!!!!

A.Cultural diversity has increased due to migration and immigration. B.The Native American population has not changed locations. C..Immigration from Pacific Rim countries has decreased due to a lack of C.work. D.African Americans arrived in the state as
