Answer:

$(a) 78.4\% = 0.784$

$(b) 29\% =0.290$

Required

As a decimal to nearest thousandth

Solving (a): 78.4%

$78.4\%$

Express as fraction

$78.4\% = \frac{78.4}{100}$

Solve fraction

$78.4\% = 0.784$ ----- This is already in thousandth place

Solving (b): 29%

What is the answer for this Problem?

Answer:

Increasing on the interval(s) $-2\leq x\leq -4$

Decreasing on the interval(s) $-1\leq y\leq 1$

Step-by-step explanation:

Anytime the graph is going upward, the function is increasing. However, anytime the graph goes down, the function is decreasing. Look at the image below for further reference. Also, when the function is increasing, the slope is positive, and when the function is decreasing the slope is negative.

The increasing interval of the graph is -3

The decreasing interval of the graph is 0.5

Since the values are in the middle of the interval, it automatically becomes the answer.
