The inverse of a square matrix A, denoted by A⁻¹.
The formula is [tex]\frac{1}{|A|}.adj(A)[/tex]
The product of A and A⁻¹ should be the identity matrix. The identity matrix that results will be the same size as matrix A.
Inverse of given first matrix is
[tex]\left[\begin{array}{cc}6&14\\-2&-4\end{array}\right][/tex]
Determinant = |A| = 6(-4) - (14)(-2)

Find the largest area for a rectangle that is inscribed in a semicircle with radius 4 inches.
The area of the largest rectangle is 25 square units.
It is given that the radius of the semicircle is [tex]4[/tex].
It is required to inscribe a rectangle of maximum area.
Consider a rectangle of sides [tex]x[/tex], [tex]y[/tex] as shown in the given figure.
From the attached figure,[tex]AB=x[/tex], [tex]OB=r[/tex] and [tex]OB=\frac{y}{2}[/tex].
Now, in the triangle OAB, apply Pythagoras' theorem as,
[tex](OA)^{2}=(OB)^{2}+(AB)^2[/tex]
[tex]r^2=(\frac{y}{2} )^2+x^2\\\\[/tex]
[tex]16=\frac{y}{4}+x^2[/tex]
[tex]y^2=4(16-x^2)[/tex]
[tex]y=2\sqrt{16-x^2}[/tex]
So, the area of the rectangle will be,
Area,
[tex]A = 2x \times y[/tex]
= [tex]2x \times \sqrt{(16 - x^2)}[/tex]
Differentiate the area with respect to ,
[tex]A' = 2 \times \sqrt{(16 - x^2)} - 2x^2/(16 - x^2)[/tex]
Differentiate the area twice as,
When[tex]x = 0, y = 5[/tex] and when [tex]x = 5, y = 0[/tex], [tex]area = 0[/tex].
It implies that area is maximum when the value of x lies between 0 and 5.
This will occur where [tex]A'= 0[/tex].
⇒ [tex]2 \times \sqrt{(16 - x2) }- 2x^2/(16 - x^2) = 0[/tex]
⇒[tex]2 \times \sqrt{(16 - x^2)} = 2x^2/(16 - x^2)[/tex]
On simplification, we get,
⇒ [tex]2 \times (16 - x^2) = 2x^2[/tex]
⇒ [tex]16 - x^2 = x^2[/tex]
⇒ [tex]2x^2= 16[/tex]
⇒ [tex]x^2 = 16/2[/tex]
⇒ [tex]x = \sqrt{8}[/tex]
Now, [tex]y = \sqrt{(16 - x^2)}[/tex] becomes
⇒[tex]y = \sqrt{(16 - (\sqrt8)^2)}[/tex]
⇒ [tex]y = \sqrt{(16 - 8)}[/tex]
[tex]y =\sqrt{8}[/tex]
Maximum area = 2xy
[tex]=2(\sqrt{8)}(\sqrt{8})[/tex]
[tex]=16[/tex]
Therefore, the area of the largest rectangle is 16 square units.

The solution of the number in the expression ''40% of a number is 36'' is 90.
Given that,
To find the solution for 40% of that number is 36.
Used the concpet of percentage which stated that,
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating the hundredth part of any quantity is called a percentage.
Let us assume that the solution of the given condition is x.
So, it can be written as,
[tex]40\% \times x = 36[/tex]
[tex]\dfrac{40}{100} \times x = 36[/tex]
Multiply both sides by 100,
[tex]40x = 36 \times 100[/tex]
[tex]40x = 3600[/tex]
Divide both sides by 40,

From the properties of a right triangle is found that the missing length x= [tex]5\sqrt{3}[/tex].
RIGHT TRIANGLEA triangle is classified as a right triangle when it presents one of your angles equal to 90º. The greatest side of a right triangle is called the hypotenuse. And, the other two sides are called legs.
The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.
The Pythagorean Theorem says: (hypotenuse)²= (leg1)²+(leg2)² . And the main trigonometric ratios are: sin (x) , cos (x) and tan (x) .
The sum of the internal angles of a right triangle also is equal to 180°.
The question gives a figure which is compound for two right triangles.
For each triangle is informed two angles, then:
Triangle 1 - It is given the angle 45° and 90°, thus the third angle will be:45+90+ x = 180
135 + x =180
x=180-135
x=45°
Triangle 2 - It is given the angle 60° and 90°, thus the third angle will be:60+90+ y = 180
150+ y =180
y=180-150
y=30°
Thus, the angles for the given triangle are:
Triangle 1 - 45°, 45° and 90°Triangle 2 - 60°, 30° and 90°From the trigonometric ratio sinФ, you can find the hypotenuse the triangle 2. See below.
[tex]sin \theta =\frac{opposite\ leg }{hypotenuse} \\ \\ sin 45 =\frac{hypotenuse \ triangle 2 }{hypotenuse \ triangle 1} \\ \\ \frac{\sqrt{2} }{2}=\frac{hypotenuse \ triangle 2 }{10\sqrt{2} }\\ \\ 2*hypotenuse \ triangle 2 = 10*2\\ \\ hypotenuse \ triangle 2 = \frac{10*2}{2} \\ \\ hypotenuse \ triangle 2 =10[/tex]
If the hypotenuse of triangle 2 is 10, you can apply again the trigonometric ratio sinФ for finding x
[tex]sin \theta =\frac{opposite\ leg }{hypotenuse} \\ \\ sin 60=\frac{x }{hypotenuse \ triangle 2} \\ \\ \frac{\sqrt{3} }{2}=\frac{x }{10}\\ \\2x=10 \sqrt3\\ \\ x=5\sqrt3[/tex]

Students in a classroom have eaten 20% of jellybeans from a jar. There are now only 100 jellybeans left! How many jellybeans were in the jar to begin with?
Using percentages we calculate in the beginning there were 125 jellybeans in the jar.
Let the number of jellybeans in the jar was x.
Now student ate 20% of the jellybeans.
Number of jellybeans students ate = 20% of x = 0.2x
Number of jellybeans left = x - 0.2x = 0.8x
But the number of jellybeans is given as 100.
Therefore 0.8x = 100
or, x = 100 /0.8 = 125
Hence there were 125 jellybeans in the jar.
The English word "percentage" derives from the Latin phrase "per centum," which means "by the hundred." Percentages are fractions with a denominator of 100.

A triangle has sides with lengths of 26 inches, 36 inches, and 46 inches. Is it a right triangle?
yes or no
Answer:
no
Step-by-step explanation:
You want to know if side lengths 26 in, 36 in, 46 in form a right triangle.
Pythagorean tripleThe integer side lengths will form a right triangle if they are a Pythagorean triple, or a multiple of one.
We notice that these side lengths have a common difference of 10 in. That makes them an arithmetic sequence. The only Pythagorean triples that are an arithmetic sequence are {3, 4, 5} and its multiples. The shortest side is 3 times the common difference.
The lengths {26, 36, 46} cannot form a right triangle. The attachment shows the triangle is an obtuse triangle.
No, the triangle is not a right triangle.

The side lengths will form a right triangle if and only if they satisfy the relation a² +b² = c², where a, b are the two short sides.

(B) Dijon Mustard: 18g
Increased by 20 = 360g(C) Barbeque sauce: 70g
Increased by 5 = 350gIncreased by 20 = 1,400g(D) Worcestershire sauce: 10.35g
Increased by 5 = 51.75gIncreased by 20 = 207g(E) Kosher salt: 1.5g
Increased by 5 = 7.5gIncreased by 20 = 30g(F) Ground black pepper: 2.3g
Increased by 5 = 11.5gIncreased by 20 = 46g(G) Crushed red pepper: 1.15g
Increased by 5 = 5.75gIncreased by 20 = 23gWhat do we mean by mathematical operations?A mathematical "operation" is the process of calculating a value utilizing operands and a math operator.There are predefined rules associated with the math operator's symbol that must be applied to the supplied operands or numbers.The order of operations is a rule that outlines the proper steps to take when analyzing a mathematical equation.We can recall the PEMDAS steps in the following order: Parentheses, Exponents, Multiplication, Division (from Left to Right), Addition, and Subtraction (from left to right).So, we can calculate missing values as follows:
(B) Dijon Mustard: 18g
Increased by 20 = 18×20 = 360g(C) Barbeque sauce: 70g
Increased by 5 = 70×5 = 350gIncreased by 20 = 70×20 = 1,400g(D) Worcestershire sauce: 10.35g
Increased by 5 = 10.35×5 = 51.75gIncreased by 20 = 10.35×20 = 207g(E) Kosher salt: 1.5g
Increased by 5 = 1.5×5 = 7.5gIncreased by 20 = 1.5×20 = 30g(F) Ground black pepper: 2.3g
Increased by 5 = 2.3×5 = 11.5gIncreased by 20 = 2.3×20 = 46g(G) Crushed red pepper: 1.15g
Increased by 5 = 1.15×5 = 5.75gIncreased by 20 = 1.15×20 = 23gTherefore, using simple mathematical operations, the missing values are as follows:
(B) Dijon Mustard: 18g
Increased by 20 = 360g(C) Barbeque sauce: 70g
Increased by 5 = 350gIncreased by 20 = 1,400g(D) Worcestershire sauce: 10.35g

kumiko decides to buy the same number of apps and games, and she decides to spend as much of the $50 as possible. how many apps and games does she buy? how much money does she have left on her gift card?
The linear inequality representing the number of apps and games that Kumiko can buy is [tex]1.25a+2.5g\leq50[/tex].
Expressions using linear inequalities compare any two values using inequality symbols like "," ">," "," or "."
The linear inequality representing the number of apps and games that Kumiko can buy is [tex]1.25a+2.5g\leq50[/tex].
What is Inequality?Expressions using linear inequalities compare any two values using inequality symbols like "," ">," "," or "." These values might be either numerical, algebraic, or both.
The number of apps Kumiko buy is a and the number of games she can buy is g.
The gift card has 50$.
Total amount of apps = 1.25a
Total amount of games = 2.5g
So, the linear equality will be [tex]1.25a+2.5g\leq50[/tex].
She can can only games and apps for amount less than and equal to $50.
Therefore, The linear inequality representing the number of apps and games that Kumiko can buy is [tex]1.25a+2.5g\leq50[/tex].
