e^{x} > 1 + x when e^{c} is removed from the expression derived by the mean value theorem.

Let be f(x) = e^{x}, for x > 0, according to the mean value theorem, also known as Rolle theorem, there is a value c\in (0, +\infty) so that:

f'(c) = \frac{f(x)-f(0)}{x-0} (1)

Where:

f'(c) - First derivative evaluated at c.

f(0) - Function evaluated at zero.

Then, we simplify the expression below:

x\cdot e^{c} = e^{x}-1

e^{x} = 1 + x\cdot e^{c}

Please that 1 + x is equalized to e^{x} because of e^{c}. If we eliminate e^{c}, then we find that e^{x} > 1 + x.

The function g is defined by:
Alisiya [41]

<em>g(x)</em> = <em>x</em>² - <em>x</em> - 6

so

<em>g</em> (-4) = (-4)² - (-4) - 6 = 16 + 4 - 6 = 14

When <em>g(x)</em> = 6, we have

6 = <em>x</em>² - <em>x</em> - 6

<em>x</em>² - <em>x</em> - 12 = 0

Solve for <em>x</em>. We factorize this easily as

(<em>x</em> - 4) (<em>x</em> + 3) = 0

which gives

<em>x</em> - 4 = 0   <u>or</u>   <em>x</em> + 3 = 0

<em>x</em> = 4   <u>or</u>   <em>x</em> = -3

Marcus has a bag of cat food that contains 22 1/2 cups.if he feeds his cats a total of 3/4 cup of food per day,how many days wil
Korvikt [17]

Answer:

30 days.

Step-by-step explanation:

22 1/2 = 45/2 since 22*2+1 = 45, then divide that by 3/4 which, in reality, means multiply by 4/3. I then cross-multiplied by finding the GCF of the diagonal pairs. I hope this helped! Please mark Brainliest if it did.
