Consider the following function. f(x) = 16 − x2/3 Find f(−64) and f(64). f(−64) = f(64) = Find all values c in (−64, 64) such th
VARVARA [1.3K]

Answer:

This does not contradict Rolle's Theorem, since f '(0) = 0, and 0 is in the interval (−64, 64).

Step-by-step explanation:

The given function is

f(x)=16-\frac{x^2}{3}

To find f(-64), we substitute x=-64 into the function.

f(-64)=16-\frac{(-64)^2}{3}

f(-64)=16-\frac{4096}{3}

f(-64)=-\frac{4048}{3}

To find f(64), we substitute x=64 into the function.

f(64)=16-\frac{(64)^2}{3}

f(64)=16-\frac{4096}{3}

f(64)=-\frac{4048}{3}

To find f'(c), we must first find f'(x).

f'(x)=-\frac{2x}{3}

This implies that;

f'(c)=-\frac{2c}{3}

f'(c)=0

\Rightarrow -\frac{2c}{3}=0

\Rightarrow -\frac{2c}{3}\times -\frac{3}{2}=0\times -\frac{3}{2}

c=0

For this function to satisfy the Rolle's Theorem;

It must be continuous on [-64,64].

It must be differentiable  on (-64,64).

and

f(-64)=f(64).

All the hypotheses are met, hence this does not contradict Rolle's Theorem, since f '(0) = 0, and 0 is in the interval (−64, 64) is the correct choice.

Simplify the ratio 3:2.1
Andre45 [30]
<h3>Answer is   10:7</h3>

=======================================================

Explanation

It sounds like you want the decimal number to become a whole number. If so, then one way is to multiply both parts by 10 to move that decimal point over one spot to the right

3*10 = 30

2.1*10 = 21

The ratio 3:2.1 is equivalent to 30:21

-----

Then notice how 30 and 21 have the greatest common factor 3. Divide both parts by 3 so we can fully reduce this ratio

30/3 = 10

21/3 = 7

The ratio 30:21 simplifies fully to 10:7

The numbers 10 and 7 do not have any factors in common, other than 1, so we cannot reduce 10:7 any further.

Subtract both fractions. Convert both fractions into improper fractions. So do 3x10+9 and see what ur answer is and put it over ten. Then do 2x16+1 and put the answer u get over 6. Then find the common denominator which is 30. Then subract both fractions and u should get ur answer
