Answers

Answer 1

The answer to the given question is b²/a²

The power of a number tells us how many times that number must be multiplied. Exponents and indexes are other names for powers. For instance, 8² denotes "8 squared," "8 squared," or just "8 squared."

A power is just an expression that denotes repeatedly multiplying the same number or factor. The exponent value depends on how frequently the base has been multiplied by itself.

For instance, 8 x 8 x 8 x 8... times is 8. The phrase 8n above is pronounced as 8 raised to the power n. As a result, exponents are also sometimes referred to as power or indices.

a⁷ b² a⁻⁹

= a⁽⁷⁻⁹⁾ b²

= a⁻² b²

= b² / a²

Therefore, The value of the given equation is b²/a²

Let AC equal the tangent to the circle with center O.

OA ⊥ AC   ....(The tangent has always been perpendicular to the radius.)

As, it is given that ∠OAC = 90° and ΔOAC is isosceles triangle.

Thus, ∠O = ∠C = x (say)

Number of matinee tickets = 900

Number of student tickets = 1800

Number of regular tickets = 5800

Algebra is the branch of mathematics that represents problems and situations in the form of mathematical expressions. It contains variables such as x, y, z, and operations such as addition, subtraction, multiplication, and division to form  meaningful mathematical expressions.

Algebra is used mostly in all areas of mathematics like trigonometry, calculus, and coordinate geometry. A simple example of an algebraic expression  is 9x + 4 = 8.

Algebra deals with symbols, and these symbols are related to each other by operators. It's not just a mathematical concept, it's a skill that we all use subconsciously in our daily lives.

Let x be the number of matinee tickets.

In that case, the number of  student tickets is 2x.

The number of regular  tickets is (8500-x-2x) = (8500-3x).

Total money

5x + 6*(2x) + 8.50*(8500-3x) = 64600

Simplifying and solving for x

5x + 12x - 8.50*3*x + 8.50*8500  = 64600

5x + 12x - 8.50*3*x = 64600 - 8.50*8500

Solving x , we get

x = 900

Number of matinee tickets = 900

Number of student tickets = 1800

Number of regular tickets = 8500 - (900+1800) = 5800

Hence, the equation of exponential function is represented by y = A(Bˣ)

An exponential function is a mathematical function of the form f(x) = ax, where "x" is a variable and "a" is a constant  called the base of the function and it must be greater than 0.

The most commonly used exponential basis is the transcendental number e, which is approximately equal to 2.71828

The equation in exponential form

y = A(Bˣ)

Case 1 :

x =0 y = 0.02

0.02 =  A (B⁰)

A = 0.02

Case 2:

x = 1 y =0.04

0.04 =  0.02(B)

0.04 /0.02 = B

B = 2

Case 3 :

x = 2 y =0.08

0.08 = 0.02(2²)

0.08 = 0.08

Case 4 :

x = 3 y = 0.16

0.16 = 0.02(2³)

0.16 = 0.16

So, we have implemented the eqaution y = A(Bˣ)

We found the values of A & B, and also proved them in case 3 and case 4.

Hence, the equation of exponential function is represented by y = A(Bˣ)

The radioactive substance remaining after 43 hours is: 62.7273 mg by unitary method.

What is unitary method?

A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method.

Now,

Given that 180 mg is present at t = 0 hours.

After t = 33 hours, substance left = 90mg

By unitary method, after = 1 hour, substance left = [tex]180-\frac{90}{33}=180 -\frac{30}{11}[/tex]mg

The substance left after t = 43 hours = [tex]180 - \frac{30\times43}{11}= 180 - \frac{1290}{11}=180 - 117=62.7273mg[/tex]

a piece of wire 100 inches long is cut into two pieces and each bent into the shape of a square. if the sum of the areas of the two squares is 400 in2, find the length of each piece of wire.

Answers

The length of the pieces of wire include 23.5425 inches and 75.4565 inches.

How to calculate the length?

Given the total length of wire is

X+Y=100

Y=100-X

Then we bend the two pieces into squares so that the sides of each square are X/4 and (100-X)/4. Therefore

(X/4)² + [(100-X)/4]² =400

X² +10000-200X +X² =6400

X²-100X+1800=0

X = 76.4565 inches and X=23.5425 inches

Answers

The triangle with vertices located at U(-5 , 5), K(-5 , -1), and L(1 , 2) has its centroid located at (-3 , 2).

The centroid of a triangle is the point inside the triangle where the three medians intersect. The median of a triangle is the line the connects the midpoint of a side and the opposite vertex.

To get the centroid of a triangle, use the formula given by:

C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]

where C is the centroid of the triangle located at (x , y)

x1, x2, and x3 are the x-coordinate of the vertices of the triangle

y1, y2, and y3 are the y-coordinate of the vertices of the triangle

Let Point 1(x1 , y1) = U(-5 , 5)

Point 2(x2 , y2) = K(-5 , -1)

Point 3(x3 , y3) = L(1 , 2)

Plug in the values in the formula.

C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]

C(x ,y) = [(-5 + -5 + 1)/3 , (5 + -1 + 2)/3]
