What is the zero of the function below?
Ymorist [56]

x = 1

Step-by-step explanation:

Given data: f(x)=3 \sqrt{x+3}-6

Recall: If f(x) = 0, then x is called the zero of the function.

To find zero of the function, take f(x) = 0.

\Rightarrow 3 \sqrt{x+3}-6=0

Add 6 to both sides of the equation.

\Rightarrow 3 \sqrt{x+3}=6

Divide both sides of the equation by 3.

\Rightarrow \sqrt{x+3}=2

Taking square on both sides of the equation.

\Rightarrow(x+3)=2^{2}  

⇒ x + 3 = 4

⇒ x = 1

Hence, the zero of the function is 1.

wo neighboring homeowners, , 2, simultaneously choose how many hours to spend maintaining a beautiful lawn. The average benefit
Fantom [35]

To calculate the average benefit of hours we must add all the values then divide by the number of values that we have.

<h3>What is the average?</h3>

Average is a term that refers to a value that represents the mean of a group of values. For example, if my friends and I have a race to run from point A to point B and our times are:

  • 69 seconds.
  • 58 seconds.
  • 45 seconds.
  • 120 seconds.
  • 76 seconds.

The average time of my group of friends would be:

69 + 58 + 45 + 120 + 76 = 368

358 ÷ 73.6 seconds

The average of my group of friends would be 73.6 seconds.

According to the above, to identify the average profit per hour of my neighbors who own their lawns, you must use the same formula to obtain the result.

Note: This question is incomplete because the are some information missing. However I can answer it based on my prior general knowledge.
