  we have to find which consective integer the real zero is present so for this we will assume
x=0:
f(0)= 3*0-10*0+22*0-4 = -4
now

<span> for: </span>x=1: 
<span>f(1)=3*1-10*1+22*1-4=3-10+22-4=11
now it means that the real zero lies between 0 and 1</span>

Umnica [9.8K]

The number of teams she can make is 10.

<h3>How many teams can she make?</h3>

Division is the process of putting a number into equal groups using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations. Other basic mathematical operations include addition, subtraction, multiplication.

The number of teams that can be made can be determined by dividing the total number of friends by the total number of players in each team. The whole number that is derived from the division process is the number of teams teams that can be made given the total number of friends and the number of people that have to be in each group.

Number of teams she can make = total number of friends / number of people in each group

31 / 3 = 10 remainder 1

So, only 10 teams can be made. one person would not be on any team.

Find the hypotenuse (c) of the right triangle.
Aleksandr-060686 [28]
<h2><u>Solution</u>:-</h2>

Hypotenuse (x) of the right triangle = \sqrt{7² \: + \: 11²}

Hypotenuse (x) of the right triangle = \sqrt{49 \: + \: 121}

Hypotenuse (x) of the right triangle = \sqrt{170}

Hypotenuse (x) of the right triangle = 13

The hypotenuse (x) of the right triangle is <u>1</u><u>3</u><u> </u><u>m</u>.

<h3>Hence, option (D) <u>1</u><u>3</u><u> </u><u>m</u> is correct. [Answer]</h3>
