Answer:

Correct answer is:

n³+4n²-8n-9

Step-by-step explanation:

We have to find the sum of:

2n³ + 4n² - 7  and  -n³ - 8n - 2

On adding both terms:

2n³ + 4n² - 7 + (-n³ - 8n - 2)

= 2n³ - n³ + 4n² - 8n - 7 - 2

= n³+4n²-8n-9

Hence, sum of 2n³ + 4n² - 7  and  -n³ - 8n - 2 is:

n³+4n²-8n-9

What is the relationship between the degree measure of the angle formed by the straight edges of a section of a circle graph as
Butoxors [25]

Answer:

  degree measure = 360° × percent of data

Step-by-step explanation:

The ratio of the degree measure of a sector of a circle graph to 360° is the same as the ratio of the represented data to the whole amount of data.

The idea of a circle graph is that the area of the sector is proportional to the data being represented. That is, if the data represented is 10% of the whole, then the sector area is 10% of the whole. Sector area is proportional to the degree measure of its central angle, so the example sector would have a central angle of 10% of 360°, or 36°.

The ratio of the central angle of the sector to 360° is the same as the percentage of data that sector represents.
