Answer:
The answer is 20ft
Step-by-step explanation:
Since they both cast shadows at the same time, the ratios of their height to their respective shadow length will be the same.
Hence; we'll equate both ratios to find the length.
House= 12/9
Flag pole= h/15
Equating both:
12/9 = h/15
h x 9 = 12 x 15
h = 180/9
h = 20ft
Sometimes the best way to tell whether two variables are associated is to ask yourself whether they are not associated. Think backward. In a two-way frequency table, if the relative frequencies for one variable are the same (or close) for all categories of another variable, there is no (or little) association.
Answer:
y=(-2/3)x^2-(2/3)
Step-by-step explanation:
2x^2+3y=-2
3y=-2x^2-2
y=(-2/3)x^2-(2/3)
