Answer:

x = -2sqrt(3), 2sqrt(3)

Step-by-step explanation:

12 - x² = 0

x² = 12

x = +/- sqrt(12)

x = +/- 2sqrt(3)

sqrt: square root

Answer:

±2 sqrt(3) =x

Step-by-step explanation:

12 - x^2 = 0

Add x^2 to each side

12 - x^2 + x^2 = x^2

12 = x^2

Take the square root of each side

±sqrt(12) = sqrt(x^2)

±sqrt(4*3) = sqrt(x^2)

±sqrt(4) sqrt(3) = x

±2 sqrt(3) =x

Find two consecutive integers whose sum is 373.
nadya68 [22]

Answer:

186 and 187

Step-by-step explanation:

Let n be the first integer.

Then n+1 is the next integer.

We are given their sum is 373.

n+(n+1)=373

Combine like terms:

2n+1=373

Subtract 1 on both sides:

2n=372

Divide both sides by 2:

n=186

So n+1=187.

187

+186

--------

373

Does the function satisfy the hypotheses of the Mean Value Theorem on the given interval? f(x) = 3x2 − 2x + 1, [0, 2] Yes, it do
expeople1 [14]

Answer:

Yes , function is continuous in [0,2] and is differentiable (0,2) since polynomial function are continuous and differentiable

Step-by-step explanation:

We are given the Function

f(x) =3x^2 -2x +1

The two basic hypothesis of the mean valued theorem are

  • The function should be continuous in [0,2]
  • The function should be differentiable in (1,2)

upon checking the condition stated above on the given function

f(x) is continuous in the interval [0,2] as the functions is quadratic and we  can conclude that from its graph

also the f(x) is differentiable in (0,2)

f'(x) = 6x - 2

Now the function satisfies both the conditions

so applying MVT

6x-2 = f(2) - f(0) / 2-0

6x-2 = 9 - 1 /2

6x-2 = 4

6x=6

x=1

so this is the tangent line for this given function.
