<h3>Given:</h3>

f(x) = 5x^2 - 13

g(x) = 8x^3 + 4

<h3>To Find:</h3>

The value of (f+g)(x) or <u>f(x) + g(x)</u> .

<h3>Explanation:</h3>

By putting the respected values, we get

f(x) + g(x) = 5x^2 - 13 + 8x^3 + 4

By simplifying the like terms, we get

<u>f(x) + g(x) = 8x^3 + 5x^2 - 9</u>

<h2>Answer:</h2>

<u>(f+g)(x) = 8x^3 + 5x^2 - 9</u>

What is the approximate area of a circle with diameter 6?
BaLLatris [955]

Answer: 28.27

Step-by-step explanation:

First, you can turn the diameter into a radius, giving you 3. Since the equation of an area in a circle is A=πr^2, you must square 3, giving you 9. Now you must multiply 9 with Pi, which is 3.14159265358, but just 3.14 for short. With that, you get about 28.27 as area.

One hundred people are surveyed and asked if they trust candidate A or candidate B or candidate C in a local election. People ar
ElenaW [278]

Answer:

5 people trust none of the candidates

Step-by-step explanation:

To know how many people surveyed trust none of the candidates we need to find:

  • People that trust all three candidates: 5
  • People that just trust candidate B and C: This is equal to people that trust candidate B and C less people that trust all three candidates. So it is equal to: 17 - 5 = 12
  • People that just trust candidate A and C: This is equal to people that trust candidate A and C less people that trust all three candidates. So it is equal to: 12 - 5 = 7
  • People that just trust candidate A and B: This is equal to people that trust candidate A and B less people that trust all three candidates. So it is equal to:  7 - 5 = 2
  • People that just trus candidate C: This is equal to the people that trust candidate C less people that just trust candidate B and C less people that just trust candidate A and C less people that trust all three candidates. So, it is equal to: 48 - 12 - 7 - 5 = 24
  • People that just trus candidate B: This is equal to the people that trust candidate B less people that just trust candidate B and C less people that just trust candidate A and B less people that trust all three candidates. So, it is equal to: 44 - 12 - 2 - 5 = 25
  • People that just trus candidate A: This is equal to the people that trust candidate A less people that just trust candidate A and C less people that just trust candidate A and B less people that trust all three candidates. So, it is equal to: 34 - 7 - 2 - 5 = 20

Therefore, we can calculate how many people surveyed trust at least one candidate by the sum of the previous quantities as:

5 + 12 + 7 + 2 + 24 + 25 + 20 = 95

Finally, there are 100 people surveyed and 95 people trust at least one candidate, so 5 people trust none of the candidates.
