Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

1) a+b+c=180 because if you take two right angle triangles and put them together you'll make a rectangle and thats 360, so half of the 360 is 180 which equals the two right triangles.

2) b and d are supplementary angles so if you add b and d they should equal 180, which is the measure of a straight line.

3) if you add c+a it should always equal d.

Answer:

1. a + b + c = 180

2. b + d = 180

3. d = a + c

Step-by-step explanation:

1. a + b + c = 180:

Angles in a triangle add up to 180

2. b + d = 180:

Angles in a straight line equal 180 because they are supplementary angles

3. d = a + c:

ΔACD is an exterior angle, and ΔACB is interior adjacent, hence ∠a and ∠c add up to ∠d

Denver gets 5/19 of the dog food.
natka813 [3]

Answer:

Fido have \frac{42}{95} of the dog food (44.211 %), Engle have \frac{28}{95} of the dog food (29.474 %) and Denver have \frac{5}{19} of the dog food (26.316 %).

Step-by-step explanation:

If Denver gets \frac{5}{19} of the dog food, then Engle and Fido share \frac{14}{19} of the dog food. If Fido have x of the dog food, then Engle have \frac{4}{3}\cdot x such that:

x + \frac{4}{3}\cdot x = \frac{14}{19}

\frac{5}{3}\cdot x = \frac{14}{19}

x = \frac{42}{95}

Fido have \frac{42}{95} of the dog food (44.211 %), Engle have \frac{28}{95} of the dog food (29.474 %) and Denver have \frac{5}{19} of the dog food (26.316 %).

Each of these extreme value problems has a solution with both a maximum value and a minimum value. Use Lagrange multipliers to f
tino4ka555 [31]

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) then find the maximum value at x=a

Problem:-

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

<u>step1:</u>- find first derivative f^{l} (x) and equating zero

  f^{l}(x) = \frac{1}{x^2+1} \frac{d}{dx}(x^2+1)

f^{l}(x) = \frac{1}{x^2+1} (2x)  ……………(1)

f^{l}(x) = \frac{1}{x^2+1} (2x)=0

the point is x=0

<u>step2:-</u>

Again differentiating with respective to 'x', we get

f^{ll}(x)=\frac{x^2+1(2)-2x(2x)}{(x^2+1)^2}

on simplification , we get

f^{ll}(x) = \frac{-2x^2+2}{(x^2+1)^2}

put x= 0 we get f^{ll}(0) = \frac{2}{(1)^2}   > 0

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

<u>Final answer</u>:-

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