Answer:

<h2>Wedge Z requires the least amount of force to do a job.</h2>

Step-by-step explanation:

In physics, Work is defined as the energy needed to move certaing object through a certain distance. Specifically, the work done is directly proportional to the force exerted and the distance.

It's important to know that a change of point is needed to have actually work done, physically speaking. This means if the object doesn't move, then there's no work done.

Mathematically, the work is defined

W= F \times d

Isolating the force

F=\frac{W}{d}

So, notice that the distance is inversely proportional to the force needed, which means the less distance, more force we need.

Now, the problem is giving wides and slopes, which we can use to find heights. And we know already that the less distance we have, the greater force we need, or the most distance, the least force.

Let's find which wedge has the greatest vertical distance.

m=\frac{y}{x}

<h3>Wedge 1.</h3>

5=\frac{y}{2} \implies y=10

<h3>Wedge 2.</h3>

8=\frac{y}{4} \implies y=32

<h3>Wedge 3.</h3>

9=\frac{y}{3} \implies y=27

<h3>Wedge 4.</h3>

10=\frac{y}{5}\\ y=50

Notice that the last wedge has greater vertical distance, that means Wedge Z requires least amount of force to do a job.

Which statement best explains whether the table represents a linear or nonlinear function? Input (x) Output (y) 2 5 4 10 6 15 8
Vinil7 [7]

Answer:

C It is a linear function because there is a constant rate of change in both the input and output.

Step-by-step explanation:

With the values, you can see that the Y value is always 2.5 times the value of X.  That's a constant rate of change.

Answers A and B make no sense, because the fact that the input or output values are increasing or decreasing have no impact to determine if a function is linear or not, can be linear or non-linear in all cases.

Answer D gives the definition of a linear function, but applies it to a non-linear function.

Pair of shoes cost three times as much as a scarf. The total cost of one pair shoes and one scarf is $32. If S represents the co
Mariulka [41]
Let's break down all the information we receive from the question.

One pair of shoes= three times as much as a scarf
One pair of shoes and one scarf= $32

We need to make an equation where 3s= pair of shoes and s=scarf. We then need to put one pair of shoes + one scarf = 32.
3s+s=32
Now add.
4s=32
You could use 4s=32 (or 32÷4=s).
