Answer:

Graph the function. f(x) = 3/5x − 5 is the line

x = o : f(0) = 3/5(0) - 5 = - 5

f(x) = 0 : 3/5x - 5 =0

3/5x = 5

3x = 25

x = 25/3

you have two points A(0; -5) B( 25/3 ; 0) you can draw the graph

The following are the ages (years) of 5 people in a room:

slava [35]

Answer:

The age of the person who entered the room is 15

Step-by-step explanation:

We are given:

Ages of 5 people in a room are:

17, 16, 15, 17, 22

A person enters room, and then the mean age of 6 people is 17.

We need to find the age of person who entered the room.

The formula to calculate mean is: $Mean=\frac{Sum\:of\:all\:data\:values}{Number\:of\:data\:Values}$

Now, in question we are given mean of 6 people that is 17

The age of 5 people are given while age of one person who enters the room is unknown.

Let age of person whose age is unknown= x

Now finding x using mean formula

$Mean=\frac{Sum\:of\:all\:data\:values}{Number\:of\:data\:Values}\\17=\frac{17+16+ 15+ 17+ 22+x}{6}\\17=\frac{87+x}{6}\\17*6=87+x\\102=87+x\\x=102-87\\x=15$

So, The value of x: x=15

Hence, the age of the person who entered the room is 15

Find the value of x for which 2x ^(1/ 2) = 32.

Mrac [35]

Answer:

The value of x will be 8

Step-by-step explanation:

We have given that $2\sqrt{x}=32$

We have to find the value of x

As $2\sqrt{x}=32$

For finding the value of x we have to square both side

On squaring both side

We done squaring both side for easy simplification

$4x=32$

So x = 8

So the value of x will be 8

So answer will be 8

svetlana [45]

Answer:

12 Newtons

Step-by-step explanation:

We can use Newton’s Second Law to find the mass first.

F = ma

9 = 3m

mass = 3

Substitute this into the second equation.

F = ma

F = 3(4)

F = 12N

Hope this helps! :D
