Answer 1

Answer:

Answer:

Teachers increase = 300 %

Step-by-step explanation:

Method to increase or decrease:

Change= Actual - Original

Actual= 48

Original= 12

Change= 48-12= 36

$P= (Change)/(Original) * 100$

$P= (36)/(12) * 100$ %

$P= 3 * 100$ %

$P= 300$ %

Each of these extreme value problems has a solution with both a maximum value and a minimum value. Use Lagrange multipliers to find the extreme values of the function subject to the given constraint. ln(x^2+1)

Answers

Answer:

The minimum value of the given function is f(0) = 0

Step-by-step explanation:

Explanation:-

Extreme value :- f(a, b) is said to be an extreme value of given function 'f' , if it is a maximum or minimum value.

i) the necessary and sufficient condition for f(x) to have a maximum or minimum at given point.

ii) find first derivative $f^(l) (x)$ and equating zero

iii) solve and find 'x' values

iv) Find second derivative $f^(ll)(x) >0$ then find the minimum value at x=a

v) Find second derivative $f^(ll)(x) <0$ then find the maximum value at x=a

Problem:-

Given function is f(x) = log ( x^2 +1)

step1:- find first derivative $f^(l) (x)$ and equating zero

$f^(l)(x) = (1)/(x^2+1) (d)/(dx)(x^2+1)$

$f^(l)(x) = (1)/(x^2+1) (2x)$ ……………(1)

$f^(l)(x) = (1)/(x^2+1) (2x)=0$

the point is x=0

step2:-

Again differentiating with respective to 'x', we get

$f^(ll)(x)=(x^2+1(2)-2x(2x))/((x^2+1)^2)$

on simplification , we get

$f^(ll)(x) = (-2x^2+2)/((x^2+1)^2)$

put x= 0 we get $f^(ll)(0) = (2)/((1)^2)$ > 0

$f^(ll)(x) >0$ then find the minimum value at x=0

Final answer:-

The minimum value of the given function is f(0) = 0

What is the value of x in the figure?

Answers

Answer:

x=65

Step-by-step explanation:

Both sides have to equal the same, which is 145. 145-15=130, 130/2=65. So basically you have to do inverse operation to solve this.

HE is 1/3 the length of HG , HE=x-3 and HG=4x-15 find HE

Answers

Answer:

HE=3

Step-by-step explanation:

Equations

With the data provided, we can set up an equation. Then we need to solve the equation. Finally, we use the just-found value of x to calculate HE.

Data:

HE=1/3 HG

HE=x-3

HG=4x-15

Replacing the last two equations in the first:

x-3=1/3(4x-15)

Multiply both sides by 3:

3(x-3)=4x-15

Operate:

3x-9=4x-15

Moving x's to the left and numbers to the right:

3x-4x=-15+9

Joining like terms:

-x=-6

Multiply by -1:

x=6

Since HE= x-3:

HE=6-3

HE=3

Answer:

x=24

Step-by-step explanation:

HE= 1/3(HG)

x-3=1/3(4x-15)

3x-9=4x-15

-x=-24

x=24
