Determine the values of the constants b and c so that the function given below is differentiable. f(x)={2xbx2+cxx≤1x>1

Lera25 [3.4K]

Assuming the function is

$f(x)=\begin{cases}2x&\text{for }x\le1\\bx^2+cx&\text{for }x>1\end{cases}$

For $f(x)$ to be differentiable, it necessarily has to be continuous. For this condition to be met, we need

$\displaystyle\lim_{x\to1^-}f(x)=\lim_{x\to1^+}f(x)=f(1)$
$\iff\displaystyle\lim_{x\to1}2x=\lim_{x\to1}(bx^2+cx)$
$\iff2=b+c$

For the derivative to exist, the one-sided limits of the derivative must also exist and be equal. We have

$f'(x)=\begin{cases}2&\text{for }x1\end{cases}$

$\displaystyle\lim_{x\to1^-}2=\lim_{x\to1^+}(2bx+c)$
$\iff2=2b+c$

Now we solve for $b$ and $c$ :

$\begin{cases}b+c=2\\2b+c=2\end{cases}\implies b=0,c=2$

Write an inequality that represents the situation. Jon can do less than 25 sit-ups on an exercise ball. How many sit-ups might J

o-na [289]

The inequality is x<25, when Jon cam do less than 25 sit-ups on an exercise ball.

Given that,

Jon can do less than 25 sit-ups on an exercise ball.

We have to find an inequity to illustrate the circumstance.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

The inequality is

Take the exercise balls as x

x<25

Therefore, the inequality is x<25, when Jon cam do less than 25 sit-ups on an exercise ball.

Answer:

hope this helps

Step-by-step explanation:

so there are 10 choices for president

then after that there are 9 choices for VP

then afte P and VP there are 8 choices for Treasurer

and finally after P, VP and T, there are 7 choices left for Secretary.

So the number of ways to fill those offices with 10 candidates is
