we get x=y =0 which gives 0 perimeter or x=y this implies rectangle must be a square
1. Method of Langrage Multipliers:
To find the extremum values of f(x,y) subject to constraint g(x,y) = k
find all values of x,y and λ, such that :
Δλ(f,x) = λΔg(x,y)
And g(x,y) = k
2. let the two side of the rectangle be x and y
therefore
f(x,y) = xy And g(x,y)= 2(x+y)=p
fₓ=λgₓ => y=2λ ----------------- 1
fy = λgy => x = 2λ----------------2
using equation and 1 and 2
λ=0, but this is not possible because tis implies x = y = 0, which gives 0 perimeter
or
x=y
Hence the rectangle must be a square

write an expression on in terms of n for the nth term of the sequence
An expression, in terms of n, for the nth term of this arithmetic sequence is aₙ = 23 - 4n.
What is an arithmetic sequence?An arithmetic sequence can be defined as a series of real and natural numbers in which each term differs from the preceding term by a constant numerical quantity.
How to calculate an arithmetic sequence?Mathematically, the nth term of an arithmetic sequence can be calculated by using this expression:
aₙ = a₁ + (n - 1)d
Where:
d represents the common difference.a₁ represents the first term of an arithmetic sequence.n represents the total number of terms.For the second term, we have:
a₂ = a₃ - d
a₂ = 11 - (-4)
a₂ = 11 + 4
a₂ = 15.
For the first term, we have:
a₁ = 4 + second term
a₁ = 4 + 15
a₁ = 19
Substituting the given parameters into the formula, we have;
aₙ = a₁ + (n - 1)d
aₙ = 19 + (n - 1)(-4)
aₙ = 19 - 4n + 4
aₙ = 23 - 4n

write the equation of a circle given the center (2, 9) and radius r = 3
Answer: x^2 + y^2 - 4x + 18y = 76 = 0
The center of the circle given is (2, 9)
radius = r
The equation of a circle for a given point is
(x - h)^2 + (y - k)^2 = r^2
Where h = 2, and y = 9
(x - 2)^2 + (y - 9)^2 = 3^2
Expand the parentheses
(x - 2) (x - 2) + (y - 9) (y - 9) = 9
(x - 2) (x - 2 ) = x* x - 2*x - 2*x + 2* 2
= x^2 - 4x + 4
(x - 2) (x - 2) = x^2 - 4x + 4
(y - 9) (y - 9) = y*y - y*9 - 9*y + 9*9
= y^2 - 18y + 81
(y - 9) (y - 9)= y^2 - 18y + 81
Therefore, the equation becomes
x^2 - 4x + 4 + y^2 - 18y + 81 = 9
Re-arrange the equation
x^2 + y^2 - 4x - 18y + 4 + 81 = 9
x^2 + y^2 - 4x - 18y = 9 - 81 - 4
x^2 + y^2 - 4x - 18y = -76
x^2 + y^2 - 4x - 18y + 76 = 0
The equation of a circle given the center (2, 9) and radius 3 is x^2 + y^2 - 4x + 18y = 76 = 0

The equation of a circle given the center (2, 9) and radius 3 is x^2 + y^2 - 4x + 18y = 76 = 0

(7x+1)°
Answer:
54 + (7x + 1) + 90 = 180° (sum of angles in triangle=180)
7x = 35
x = 5
Answer:
x = 5
Step-by-step explanation:
Geometry TheoryThis question deals with a right-angled triangle. The sum of the angles in a triangle is equal to 180 degrees. A right angle is equal to 90 degrees which means that the other two angles must equal to 90 degrees as well.
AlgebraForm the equation.
( 7x + 1 ) + 54 + 90 = 180;
Subtract 90 from both sides.
7x + 1 + 54 + 90 - 90 = 180 - 90;
7x + 1 + 54 = 90;
Simplify left-hand side.
7x + 55 = 90;
Subtract 55 from both sides.
7x + 55 - 55 = 90 - 55;
7x = 35;
Divide both sides by 7.
x = 35 / 7;
x = 5;

What is a log?
The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which a set number, base b, must be increased in order to create a specific number x, is represented by the logarithm of that number. The logarithm, in its most basic form, counts the number of times the same factor appears when multiplied repeatedly; for instance, since 1000 = 10 x 10 x 10 = 103, its "logarithm base 10" is 3, or log10 (1000) = 3. When there is no possibility of a mistake or when the base is irrelevant, as, in big O notation, the logarithm of x to base b is written as loga (x), logb x, or even without the explicit base, log x.

Step-by-step explanation:
f(3) means what is the value of f(x) when x = 3
substitute x = 3 into f(x)
f(3) = 10(3) + 13 = 30 + 13 = 43
similarly for x = - 8
f(- 8) = 10(- 8) + 13 = - 80 + 13 = - 67
given f(x) = 10x + 13 and f(x) = 53 , equate the right sides
10x + 13 = 53 ( subtract 13 from both sides )
10x = 40 ( divide both sides by 10 )

Equation of the line is y = -(1/3)x+5
The figure shows a straight line of which two points and thereby the slope can be found out.
Equation of a line is in the slope-intercept form is,
y = mx +c,
where m is the slope of the line and c is the y-intercept of the line.
From the figure, two points on the line are, (0,5) and (3,4).
Then slope = (4-5)/(3-0)
= -1/3
Now y-intercept, c is the y-co-ordinate when x = 0.
From the figure, when x = 0, y = 5
So y-intercept, c = 5.
Thus the equation of the line is, y = -(1/3)x+5

You are on the prom decorating committee and are in charge of buying balloons. you want to use both latex and mylar balloons. The latex balloons cost $.10 each and the mylar balloons cost $.50 each. You need 125 balloons and you have $32.50 to spend. how many of each can you buy?
I can buy 75 latex balloons and 50 mylar balloons.
This is a problem from an algebraic equation. We can solve this problem by following a few steps.
We need 125 balloons. Let's assume we have to purchase x latex balloons.
So, mylar balloons are ( 125 - x ).
Our total budget is $32.50.
The cost of x latex balloons is ($.10 × x) = $.10x , as the latex balloons cost $.10 each.
The cost of ( 125- x) mylar balloons is $[( 125- x) × 0.50] , as the mylar balloons cost $.50 each.
So the total cost is,
$[( 125- x) × 0.50] + $.10x = 32.50
Now, we have to solve this equation, Let's simplify it.
62.50 - 0.50x + .10x = 32.50
Or, 62.50 - 0.40x = 32.50
Or, -0.40x = 32.50 - 62.50 [ deduce 62.50 from both side ]
Or, -0.40x = -30 [ we should devide both sides 0.40 ]
Or, x = 30/0.40 = 75
So, the number of latex balloons is 75. Therefore, the number of remaining mylar balloons is ( 125 - 75) = 50

If the equation is correct as written, 3y = 1, then y = 1/3
y^3 = 1
This can also be written as y^2*y = 1
1. If y = -1, then y^2y would be (1)*(-1) = -1
2. If y = 1, then (1)^3 * (1) = 1 This works.

Can you please help me with this question I don’t understand it.From DA to the angle BAC
INFORMATION:
We have the next rhombus
And we must find the measure of
Knowing that DB = 10, BC = 13, and m∠WAD = 25°
STEP BY STEP EXPLANATION:
To find all measures, we need to use properties or the rhombus:
- DA: To find DA we need to know that all sides of the rhombus are equal. So, if BC measures 13, then DA measures 13 too.
- BW: To find BW we need to know that in a rhombus, diagonals bisect each other at right angles. That means, diagonals intersect in the middle. So, if DB = 10, then BW will be half of BD. BW = 10/2 = 5.
- WC: We can find it as one of the legs of the right triangle formed by BW, BC and WC. Where, BC is the hypotenuse.
[tex]\begin{gathered} 13^2=5^2+WC^2 \\ WC=\sqrt{13^2-5^2} \\ WC=12 \end{gathered}[/tex]So, WC = 12.
- Angle BAC: To find this angle, we need to use that the interior triangles formed in the interior of the rhombus are congruent. So, angle BAC is congruent with the angle DAC. Then, BAC = 25°.
ANSWER:
DA = 13
BW = 5
WC = 12
BAC = 25 degrees
