What is the total number of relative maximum and minimum points of the function whose derivative for all x is given by f ‘ (x) =

Alexeev081 [22]

Answer:

There are in total 3 maximum and minimum points of f(x)

Step-by-step explanation:

To find the number of stationary points (maximum and minimum points) in any function (f(x)), we need to find for what values of x does the derivative of f(x) equal to 0.

mathematically, for how many values of x does f'(x) = 0

$f'(x) = x(x-3)^2(x+1)^4$

$0 = x(x-3)^2(x+1)^4$

since the factors can be separately solved we can write

$0 = x, 0 = (x-3)^2, 0 = (x+1)^4$

$x= 0, \sqrt{(x-3)^2} = \sqrt{0}, \sqrt{(x+1)^4}=\sqrt{0}$

$x=0, (x-3)=0, (x+1)=0$

$x = 0, x = 3, x = -1$

Since there are 3 answers of x for which f'(x) = 0, we can say that the there are a total of 3 stationary (maximum or minimum) points in f(x).

The hypotenuse of a right triangle is 10 meters and its

liberstina [14]

<h2><u>Solution</u> :</h2>

Let's solve by using Pythagoras theorem,

$\hookrightarrow \: (10) {}^{2} = {(x})^{2} + (x + 2) {}^{2}$

$\hookrightarrow \: 100 = {x}^{2} + {x}^{2} + 4x + 4$

$\hookrightarrow \: 100 - 4 = 2 {x}^{2} + 4x$

$\hookrightarrow \: 96 = 2 {x}^{2} + 4x$

$\hookrightarrow \: 2 {x}^{2} + 4x - 96 = 0$

$\hookrightarrow \: 2( {x}^{2} + 2x - 48) = 0$

$\hookrightarrow \: {x}^{2} + 2x - 48 = 0$

$\hookrightarrow \: {x}^{2} + 8x - 6x - 48 = 0$

$\hookrightarrow \: x(x + 8) - 6(x + 8) = 0$

$\hookrightarrow \: (x + 8)(x - 6) = 0$

now there are two cases

Case 1 : when (x + 8) = 0

$\hookrightarrow \: x + 8 = 0$

$\hookrightarrow \: x = - 8$

but the value of x can't be negative, since side of a triangle isn't a negative value .

Case 2 : when (x - 6) = 0

$\hookrightarrow \: x - 6 = 0$

$\hookrightarrow \: x = 6$

therefore the measure of other two sides are :

$\hookrightarrow \: x = 6 \: units$

$\hookrightarrow \: x + 2 = 6 + 2 = 8 \: units$
