Answer:  The speedometer read Hank's miles per hour as 20% more than the miles per hour that he actually drove.

Explanation: 20% of 50 which is the miles per hour he actually drove is 10 and 50 + 10 = 60 which is the incorrect miles per hour his speedometer read.

scoundrel [369]

Rewrite this symbolically: 6(2/6) = 12/6 = 2 (answer)

Use the graph of the function to estimate the intervals on which the function is increasing or decreasing. (Enter your answers u
Crank

The intervals on which the graph is increasing:   ]-∞,-3[ U ]0.5,-∞[ . On the other hand, the graph is decreasing:  ]-3,0.5[

<h3>Function</h3>

A function can be classified as increasing or decreasing. Thus, a function is increasing when the y-values increase, on the other hand, a function is decreasing when the y-values decrease.

From the image, you can see that the y-values increase in the following x-intervals: from -∞ to -3 and from 0.5 to ∞. Using interval notation, you can write that the function is increasing in:

                                  ]-∞,-3[ U ]0.5,-∞[

From the graph, you can see that the y-values decrease in the following x-intervals: from -3 to 0.5. Using interval notation, you can write that the function is decreasing in:

                                         ]-3,0.5[

nexus9112 [7]

Answer:

1. Exponent

2. Multiplication

3. Subtraction

4. Square root

5. Addition

6. Division?

<em>Note: I am not very sure about my answer because of two things. 1. The proper order for operating is PEDMAS (Parentheses, Exponent, Multiplication, division, addition, and subtraction). There is no Square root in that operation so I will consider it in the middle. 2. There is no division operation in this problem.</em>
