Answer:

Solution is $\frac{-6}{5}$

Step-by-step explanation:

$\frac{4}{5} - 2$

Set common denominators

$\frac{4}{5} - \frac{10}{5}$

Subtract

$\frac{4}{5} - \frac{10}{5} = \frac{-6}{5}$

Step-by-step explanation:

first we will take comman then

$\frac{4}{5} - \frac{2 \times 5}{5}$

then 4 - 10

it will be

$\frac{6}{5}$

$1 \frac{1}{5}$

i hope it will help

Answer the following questions about the function whose derivative is f primef′(x)equals=x Superscript negative three fifths Ba

Elden [556K]

Answer:

(a) The critical points of f are x=0 and x=3.

(b)f is decreasing on $(0,3)$ and f is decreasing on $(3,\infty)$ .

(c) Therefore the local minimum of f is at x=3

Step-by-step explanation:

Given function is

$f'(x)= x^{-\frac35}(x-3)$

(a)

To find the critical point set f'(x)=0

$\therefore x^{-\frac35}(x-3)=0$

$\Rightarrow x=0,3$

The critical points of f are 0,3.

(b)

The interval are $(0,3)$ and $(3,\infty)$ .

To find the increasing or decreasing, taking two points one point from the interval (0,3) and another point $(3,\infty)$ .

Assume 1 and 4.

Now $f'(1)=(1)^{-\frac35}(1-3)$

and $f'(4)=(4)^{-\frac35}(4-3)>0$

Since 1∈ $(0,3)$ , f'(x)<0 and 4∈ $(3,\infty)$ , f'(x)>0

∴f is decreasing on $(0,3)$ and f is decreasing on $(3,\infty)$ .

(c)

$f'(x)= x^{-\frac35}(x-3)$

Differentiating with respect to x

$f''(x)=-\frac35x^{-\frac 85}(x-3)+x^{-\frac35}$

Now

$f''(0)=-\frac35(0)^{-\frac 85}(0-3)+(0)^{-\frac35}=0$

and

$f''(3)=-\frac35(3)^{-\frac 85}(3-3)+3^{-\frac35}$

$=0.517>0$

Since f''(x)>0 at x=3

Therefore the local minimum of f is at x=3

Bill was looking at 13 different colors to paint his bedroom. He liked about three fourths

d1i1m1o1n [39]

Answer:

As a fraction: 39/4 or 9 3/4

As a decimal: 9.75

As a percentage: uhhhhh- 75% of the colors.

As an integer: 10

Step-by-step explanation:

Multiplying fractions, you get 39/4 or 9 3/14

Pull out your calculator(or divide on paper), to get 9.75

Round that to 10.

3/4 = 75%

Hope this helps!
