When x pounds of force is applied to one end of a lever that is L feet long, the resulting force y on the other end is

1 answer:

3 0

The question is worded poorly, but it looks like you have a lever in equilibrium, with a force x at a distance d from the fulcrum, and a force y at a distance L - d from the fulcrum. You already have the equilibrium formula for this situation:

xd = y(L - d)

If you know x, y, and d, you can solve for the length L.

What is the y-intercept of 2g(x)+3x=6?

umka21 [38]

The y-intercept is basically the value of the output of the function, g(x), when x=0.

Let's replace g(x) with the variable y to make this look a bit simpler.

2y + 3x = 6

Now, we enter the value of x=0 to get the y-intercept.

2y + 0 = 6

2y = 6

Divide both sides by 2

y = 3

The value of y is 3. Now enter the values of x=0 and y=3 into point-form (x,y) to get (0,3). You should know which answer choice to choose now.

Answer with Step-by-step explanation:

$a) {n}^{2} + 3 \\ \\ n = 1 \\ {1}^{2} + 3 \\ 1 + 3 \\ = 4 \\ \\ n = 2 \\ {2}^{2} + 3 \\ 4 + 3 \\ = 7 \\ \\ n = 3 \\ {3}^{2} + 3 \\ 9 + 3 \\ = 12 \\ \\ n = 4 \\ {4}^{2} + 3 \\ 16 + 3 \\ = 19 \\ \\ n = 10 \\ {10}^{2} + 3 \\ 100 + 3 \\ = 103$

In this sequence,

1st term = 4

2nd term = 7

3rd term = 12

4th term = 19

10th term = 103

$b)2 {n}^{2} \\ \\ n = 1 \\ 2 \times {1}^{2} \\ 2 \times 1 \\ = 2 \\ \\ n = 2 \\ 2 \times {2}^{2} \\ 2 \times 4 \\ = 8 \\ \\ n = 3 \\ 2 \times {3}^{2} \\ 2 \times 9 \\ = 18 \\ \\ n = 4 \\ 2 \times {4}^{2} \\ 2 \times 16 \\ = 32 \\ \\ n = 10 \\ 2 \times {10}^{2} \\ 2 \times 100 \\ = 200$

in this sequence,

1st term = 2

2nd term =8

3rd term = 18

4th term =32

10th term = 200

Answer:

Step-by-step explanation:

If the polygons are similar, this means that the ratio of their corresponding sides are equal. This ratio is what we commonly refer to as the scale factor. The ratio of the area of similar polygons is equal to the SQUARE of SCALE FACTOR. For this item since the scale factor is 2, the ratio of the areas is equal to 4.
