A force of 125 newtons stretches a spring 0.15 meters. What force is required to stretch it 0.25 meters??

Ilya [14]

Answer:

Step-by-step explanation:

A spring has a force formula of F = k*x

f = 125 N

x = 0.15 m

125 = k*0.15

k =833.33

F = ?

k = 833.33

x = 0.25 m

F = 833.33 * 0.25

F = 208.33 N

You could do this without solving for k

F1/F2 = x1/x2

F1 = 125 N

F2 = ?

x1 = 0.15

x2 =0.25

125 / F2 = 0.15 / 0.25 Cross multiply

125 * 0.25 = 0.15 * F2 Divide by 0.15

125*0.25 /0.15 = F2

F2 = 208.33 just as you got above

Using the following image, find the slope of the line.

dexar [7]

Answer:

-3

Step-by-step explanation:

To find slope you first need to pick to points where the line crosses a corner.

Slope= $\frac{Rise}{Run}$

I'm using the points (0,-2) and (-1,1). You can either count up and over for the slope or use the slope equation

$\frac{y2-y1}{x2-x1}$

y2=second y point

y1=first y point

x2=second x point

x1=first x point

$\frac{1-(-2)}{-1-0}$ Now you just solve

$\frac{3}{-1}$ or -3

Solve the following equation for dd. Be sure to take into account whether a letter is capitalized or not.

AlekseyPX

Answer:

$d=\frac{H}{m+6}$

Step-by-step explanation:

The equation given is:

$-6d+H=md$

We take d's to one side and others to another side of the equal sign. Thus,

$-6d+H=md\\H=md+6d$

<u>Note:</u> remembering to change signs when changing sides

Now, we want to isolate d on the RHS:

$H=md+6d\\H=d(m+6)$

To make "d" the subject, we divide both sides by "m+6", to get our answer:

$H=d(m+6)\\\frac{H}{m+6}=\frac{d(m+6)}{m+6}\\d=\frac{H}{m+6}$

This is the answer.
