He design on Santana's wall includes 16 pink stripes and 20 green stripes. Find the pink stripes to green stripes?

bija089 [108]

Well the ratio is 16:20 which it 16/20. We can simplify that to 4/5. Therefore the ratio from pink stripes to green stripes will be 4:5

Example: Does the point (5, 2) lie within the solution set of the given system of inequalities?

y ≤ x − 5

y ≥ −x − 4

Focus on the first inequality. Does (5,2) satisfy this inequality? Is 2 ≤ 5 - 0 true? Yes, it is true. Before we call (5,2) a solution, we must determine whether or not (5,2) also satisfies the 2nd inequality: Is 2 ≥ -(5) - 4 true?

Is 2 ≥ -9? Yes! So, yes, (5,2) is a solution of this system of inequalities.

We must check out the other three possible solutions in the same fashion.

Try out the point (5,-2). Does it satisfy both inequalities?

Focusing on the first inequality: Is -2 ≤ 5 - 5 true? Yes, it is. The key question here and now is whether or not (5,-2) also satisfies y ≥ −x − 4. Is

-2 ≥ -(5) - 4 true? Is -2 ≥ -9 true? Yes. Thus, (5,-2) satisfies both inequalities and is thus another solution.

Check out (-5,2) and (-5,-2) in precisely the same way. Is either one, or are both, a solution (or solutions) to the given set of inequalities?

How to tell if speed is increasing or decreasing calculus?

Reptile [31]

You will need data that logs the changes in speed from various, consecutive events. Which you can use to calculate the difference in speed and determine wether the speed is increasing or increasing.

Otherwise, you only need the initial and finak value to find the difference.

$final \: - \: initial \: = \: difference$
