NEED TO SHOW ALL WORK) For each of the equations given below, use the triangle method to solve for the
Lelechka [254]

Answer:

1) a=\dfrac{F}{m}

2) m=\dfrac{p}{v}

Step-by-step explanation:

1) The given equation is

F=ma

We need to solve this for a.

In the given triangle place single variable i.e., F, on the top and variables in the product in the bottom (order of m and a does not matter) as shown in the below figure.

Using the triangle and the operations (× and ÷), we get

F=ma

a=\dfrac{F}{m}

m=\dfrac{F}{a}

Therefore, the required answer is a=\dfrac{F}{m}.

2) The given equation is

p=mv

We need to solve this for m.

In the given triangle place single variable i.e., p, on the top and variables in the product in the bottom (order of m and v does not matter) as shown in the below figure.

Using the triangle and the operations (× and ÷), we get

p=mv

m=\dfrac{p}{v}

v=\dfrac{p}{m}

Therefore, the required answer is m=\dfrac{p}{v}.

How many line segments would you use to draw 14 pentagons
AfilCa [17]
The ratio for this problem is 1:5.

If you are drawing 14 pentagons, you would do 14 x 5.

14 (pentagons) x 5 (line segments) = 70 line segments in total.

What is the graph of the linear inequality y≤−3x+4?
tatiyna

Answer:

It would look like the picture I attached at the bottom.

Step-by-step explanation:

We know that the slope is -3 and the y intercept is (0,4) (plugging in 0 for x will get you that point), and then you can just graph an equation like you normally would, using rise/run to go down 3 units for every one unit you go right, and plugging in easy x values to check your work.

It gets a little tricky because the question then adds the inequality, and we see that y is now less than <em>or equal to </em>the original equation.

Since it is less than, we can shade all the values below the graph.

(Also, you should probably note for future reference that if it was just less than, the shading would look the same while the graph itself would be dotted because the values on the line are nor included in the solution set).

Desmos is a great website to use if you're having trouble graphing in the future :)
