answer:
22 weeks
step-by-step explanation:
- set up a proportion
- use x for how long it would take her
- cross multiply to solve
39 / 2 = 429 / x
429 (2) = 39x
858 = 39x
x = 22
- it would take her 22 weeks
- you can change the units by conversion based on what is asked
Answer:
Step-by-step explanation:
First, we can transform y = cos(x) to y = 3*cos(x) by stretching the graph vertically by a factor of 3. At x = 0, the y value would now be 3 * 1 = 3 instead of 1 (the stretching would cause all new y-values to be 3 times their original values for any given x).
Now transforming y = 3*cos(x) to y = 3*cos(10*x) will stretch the graph horizontally by a factor of 10 (for any given y value, the new x value corresponding to it is 10 times the original x value).
Finally, to transform y = 3*cos(10*x) to y = 3*cos(10(x-pi)), shift the graph to the right by pi.
