The max value and min value can then be determined from these critical points.
To find the extreme values of a function subject to a constraint, we can use Lagrange multipliers. First, we set up the Lagrangian equation by multiplying the constraint by a scalar λ and adding it to the original function.
Then, we take the partial derivatives of the Lagrangian equation with respect to each variable and set them equal to zero. This will give us a system of equations to solve for the critical points.
Once we have the critical points, we need to determine which ones are maximums and which are minimums.
To do this, we can use the second derivative test. If the second derivative is positive at a critical point, it is a minimum. If the second derivative is negative, it is a maximum.
In summary, to find the extreme values of a function subject to a constraint using Lagrange multipliers, we set up the Lagrangian equation, solve for the critical points, and then use the second derivative test to determine which ones are maximums and which are minimums.

The maximum value of f(x, y, z) is 26.5, and the minimum value is -29.
How did we get the values?To find the extreme values of the function f(x, y, z) = 6x + 6y + 5z subject to the constraint 3x² + 3y² + 5z² = 29 using Lagrange multipliers, set up the following system of equations:
1. ∇ f = λ∇g
2. g(x, y, z) = 3x² + 3y² + 5z² - 29
where ∇f and ∇g are the gradients of f and g respectively, and λ is the Lagrange multiplier.
Taking the partial derivatives, we have:
∇ f = (6, 6, 5)
∇g = (6x, 6y, 10z)
Setting these two gradients equal to each other, we get:
6 = 6λx
6 = 6λy
5 = 10λz
Dividing the first two equations by 6\(\lambda\), we obtain:
x = ¹/λ
y = ¹/λ
Substituting these values into the third equation, we have:
5 = 10λz
z = ¹/2λ
Now, substitute x, y, and z back into the constraint equation to find the value of λ:
3(¹/λ)² + 3(¹/λ)² + 5(1/2λ)² = 29
6(¹/λ²) + 5(⁴/λ²) = 29
24 + 5 = 116λ²
116λ² = 29
λ² = ²⁹/₁₁₆
λ = ±√²⁹/₁₁₆
λ = ± √²⁹/2√29
λ = ± ¹/₂
We have two possible values for λ, λ = ¹/₂ and λ = ¹/₂
Case 1: λ = ¹/₂
Using this value of λ, we can find the corresponding values of x, y, and z:
x = ¹/λ = 2
y =¹/λ = 2
z = 1/2 λ = ¹/₂
Case 2: λ = -1/2
Using this value of λ, find the corresponding values of x, y, and z:
x = 1/λ = -2
y = 1/λ = -2
z = 1/(2λ) = -1
Now that we have the values of x, y, and z for both cases, substitute them into the objective function f(x, y, z) to find the extreme values.
For Case 1:
f(x, y, z) = 6x + 6y + 5z
= 6(2) + 6(2) + 5(1/2)
= 12 + 12 + 2.5
= 26.5
For Case 2:
f(x, y, z) = 6x + 6y + 5z
= 6(-2) + 6(-2) + 5(-1)
= -12 - 12 - 5
= -29
Therefore, the maximum value of f(x, y, z) is 26.5, and the minimum value is -29.

Estelle's graduation picnic will cost $15 if it has 5 attendees. If there are 26 attendees, how much will Estelle's graduation picnic cost? Solve using unit rates.
Answer:
You can try to do a direct rule of three in this exercise.
We can considerr that the relation is proportional and we know that in this case it's dorect, as the more attendees there come, the more Estelle will have to pay, so we can write this and get x:
5 attendees - 15 dollars
26 attendees - x dollars
x = 26*15 / 5 = 78 dollars
So you know how much Estelle would have to pay

Translate X(2,3) Y(0,0) Z(4,4) 2 units right and 3 units up
Answer:
X(4, 6) Y(2, 3) Z(6, 7)
Step-by-step explanation:
If you want to translate something right on a number line, then you are essentially adding to it. Thus you would just add 2 to each of the x values of the coordinates. The same applies with translating something up, all that really means is that you are adding to each of the y values so all you have to do is add 3 to each of the y values and you get your answer.
Answer:
X:(4,6), Y:(2,3), Z:(6,7)
Step-by-step explanation:
2 units right implies a change on the x-axis, meaning you add 2 units to the x of the coordinate pair (x, y). 3 units up implies a change in Y, you apply the same rule and add 3 to the Y of the pair.
2 units right (add 2 to x pair coordinate)
X: (2,3) --> (4,3)
Y: (0,0) --> (2,0)
Z:(4,4) --> (6,4)
and 3 units up (add 3 to y pair coordinate)
X: (4,3) --> (4,6)
Y: (2,0) --> (2,3)
Z: (6,4) --> (6,7)

A movie theater is located at (1,7) after walking 6 blocks to the movie theater you meet you friend at your friend's house. What ordered pair corresponds to the location of your friend's house
Answer:
(-5,1)
Step-by-step explanation:
Given the coordinate of the location of the theatre as (1,7)
If this was the coordinate after moving 6 blocks to your friend's house, then the coordinate of the location of my friend house will be gotten as thus;
C = (1-6, 7-6) (since he moved 6blocks)
C = (-5, 1)

a. x = 12, y = 84, z = 20
b. x = 6, y = 174, z = 20
c. X= 6, y = 84, z = 10
d. x = 12, y = 174, z = 10
For the M1 angle, we can conclude the size of angle is 90°. Do the angle equation like this :
15x=90
x = 90/15
x = 6
Do the same thing in M2 :
Subtitute the x value to equation, then evaluate the value by using 90 because it's the same.
x+y=90
6+y=90
y=90-6
y=84
M3 value is same, 90°
9z=90
9z/9 = 90/9
z=10

The graph of a linear function is often a parabola.
True or False
A linear function has a graph as a straight line so the given statement is False.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
A linear function is given by
y = mx + c where m is the slope and constant.
Since it is constant it means it should be a straight line in coordinate geometry.
Therefore a linear function always makes a straight line, not a parabola.
Hence "A linear function has a graph as a straight line so the given statement is False".
