Edna has a segment with endpoints f(4, 9) and g(7, 2) that is divided by a point h such that fh and gh form a 1: 3 ratio. she knows that the distance between the x-coordinates is 3 units. which of the following fractions will let her find the x-coordinate for point h?

1 over 4
1 over 3
3 over 4
3 over 1

answer:

a. 1/4

step-by-step explanation:

because the ratio is 1: 3 you need to divide the graph into 4 equal parts (1+3=4) or 1/4.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
