Is the table proportional?

Mathematics

No. In order to be proportional, y must change directly with x.

Looking at the first two pieces of data, let's find the ratio between x and y.

2/5 and 3/6. These should be equivalent of the table is proportional.

7x + 2y=24<br> 8x + 2y=30
Bumek [7]

Answer:

x=6 y=-9

Step-by-step explanation:

  • Layer the equations on each other as you would in a subtraction problem:

               8x + 2y=30

               7x + 2y=24  

  • Subtract the equation just like you would normally. This should leave 1x=6 or x=6.
  • Now that you have your x value, plug it in as x for one of the equations. For the 2nd equation, this leaves:

               42+2y=24 then

               2y=-18 then

               y=-9

  • Double check your y value by plugging x=6 into the first equation. This should also leave y=-9.

Find the expansion of cos x about the point x=0
ycow [4]

Answer:

Cos x = 1 - \frac{x^2}{2!} + \frac{x^4}{4!} - \frac{x^6}{1!} + ...

Step-by-step explanation:

We use Taylor series expansion to answer this question.

We have to find the expansion of cos x at x = 0

f(x) = cos x, f'(x) = -sin x, f''(x) = -cos x, f'''(x) = sin x, f''''(x) = cos x

Now we evaluate them at x = 0.

f(0) = 1, f'(0) = 0, f''(0) = -1, f'''(0) = 0, f''''(0) = 1

Now, by Taylor series expansion we have

f(x) = f(a) + f'(a)(x-a) + \frac{f''(a)(x-a)^2}{2!} + \frac{f'''(a)(x-a)^3}{3!} + \frac{f''''(a)(x-a)^4}{4!} + ...

Putting a = 0 and all the values from above in the expansion, we get,

Cos x = 1 - \frac{x^2}{2!} + \frac{x^4}{4!} - \frac{x^6}{1!} + ...
