Given CB is 7 and angle A is 25, find the value of triangle ABC.

Answer:

The volume V of a rectangular prism is given by the formula V = lwh, where l, w, and h are the length, width, and height, respectively.

In this case, we have l = 2, w = 7/3, and h = 2. Therefore, the volume is:

V = (2)(7/3)(2)

V = 28/3

V = 9.33 (rounded to two decimal places)

So the volume of the rectangular prism is approximately 9.33 cubic units.

In mathematics, a function is a relation between a set of inputs (the domain) and a set of possible outputs (the codomain) with the property that each input is related to exactly one output. Functions are often represented using function notation, where the input is the independent variable and the output is the dependent variable. Functions are used to model relationships between different quantities or variables, and are an essential tool in many areas of mathematics, science, engineering, economics, and more. They allow us to make predictions, analyze data, and understand complex systems.

Here,

The exponential function y = 9*(13)^x means that for any given value of x, we can calculate the corresponding value of y by plugging in x and performing the calculation. The base of the exponential function is 13, which means that the function will increase rapidly as x gets larger.

For example, if x = 0, then y = 9*(13)⁰ = 91 = 9.

If x = 1, then y = 9(13)¹ = 913

= 117.

If x = 2, then y = 9(13)² = 9*169

= 1521.

And so on.

Answer:

We can simplify the given expression using the rules of exponents and radicals:

4xy³√ 27x^2y^5

= 4xy * ³√(27x^2y^5) (since y and ³√(27) cannot be simplified further)

= 4xy * ³√(3^3 * x^2 * y^3 * y^2)

= 4xy * 3xy * ³√y^2

= 12x^2y^2 * ³√y^2

Therefore, the expression 4xy³√ 27x^2y^5 simplifies to 12x^2y^2 * ³√y^2.

Step-by-step explanation:

What exactly are function and example?

A function is a type of rule that produces one output from one input.   This is illustrated by the equation y=x2. You only get one output for y if you enter anything for x.

                        Considering that x is the input value, we would state that y is a function of x.

f(x) = {  5;  x< 1 }

        { -1/2x + 4 ; x≥ 1 }

 f(4) =  { -1/2  * 4 + 4 }

         =  { -2 + 4 }

         = { 2 }

f( -2) =  { -1/2 * -2 + 4 }

         =  { 1 + 4 }

          = 5

3f(0) = { -1/2 * 0 + 4 }

A lοgarithm is an inverse οperatiοn tο expοnentiatiοn. It is a mathematical functiοn that helps tο sοlve equatiοns where the variable is in the expοnent. The lοgarithm οf a number tο a certain base is the expοnent tο which the base must be raised tο get that number.

Accοrding tο given infοrmatiοn :

In the given expressiοn, 1,000 • e0.034t, the variable "t" represents the time in years, and "e" is a mathematical cοnstant called Euler's number (apprοximately 2.71828).

The entire expressiοn represents the amοunt οf mοney in an accοunt after "t" years, assuming an initial investment οf $1,000 and a cοntinuοus interest rate οf 3.4% per year (0.034 in decimal fοrm).

Tο find the number οf years it will take fοr the accοunt tο reach $15,000, we can set the expressiοn equal tο 15,000 and sοlve fοr "t".

1,000 • e0.034t = 15,000

Dividing bοth sides by 1,000 gives:

e0.034t = 15

Tο sοlve fοr "t", we can take the natural lοgarithm (ln) οf bοth sides:

ln(e0.034t) = ln(15)

0.034t • ln(e) = ln(15)

Since ln(e) = 1, we can simplify tο:

0.034t = ln(15)

Dividing bοth sides by 0.034 gives:

t = ln(15) / 0.034

Using a calculatοr, we get:

t ≈ 23.29

The zeros ( roots ) of the function y = (x + 2)^2 - 25 are x = 3 and x = -7.

Given the function in the question;

y = ( x + 2 )² - 25

To find the zeros of the function, simply means find the values of  x in the function y = ( x + 2 )² - 25, when y equals zero.

Equat the function to 0

(x + 2)^2 - 25 = 0

Adding 25 to both sides, we get:

(x + 2)^2 - 25 + 25  = 0 + 25

(x + 2)^2  = 25

Taking the square root of both sides, we get:

x + 2 = ±√25

x + 2 = +5

Solving for x, we get:

x = -2 + 5 = 3

or x = -2 - 5 = -7

Therefore, the zeros of the function are 3 and -7.

Therefore , the solution of the given problem of triangle comes out to be L = 3(√(h²) + ((w/2²))) + 3h .

A triangular is a polygon because it has 2 different or more additional parts. It has a straightforward rectangle form. Only the sides A, B, and C can differentiate a triangle from a parallelogram. When the sides are not exactly collinear, Euclidean geometry results in a singular surface rather than a cube. If a shape has three edges and three angles, it is said to be triangular.

Here,

Given the height and breadth of the top of the frame, we can use the Pythagorean theorem to determine the length of each side of the triangle.

Let's assume the height is h feet and the width of the top of the frame is w feet. The triangle's side lengths can then be calculated as follows:

=> s =√((h²) + ((w/2)²))

We must add up the lengths of all the pipe segments that will be used to build the frame in order to determine the total quantity of steel pipe required.

The following formula can be used to determine how much steel tubing is required:

=>  L = 3s + 3h

where h is the height of the frame and s is the length of each edge of the triangle.

Using the method instead of s, we obtain:

=> L = 3(√(h²) + ((w/2²))) + 3h

Step-by-step explanation:

The angle measure of minor arc QS is 92 degrees, and the angle measure of angle QQS is 46 degrees.

What is Angle?

In geometry, an angle is a figure formed by two rays that have a common endpoint, called the vertex of the angle. The rays that form the angle are called the sides of the angle. Angles are typically measured in degrees or radians and are used to describe the amount of rotation between two intersecting lines or planes.

In a circle, the measure of an inscribed angle is equal to half the measure of the intercepted arc. Since QS intercepts the minor arc QR, the measure of angle QRS is equal to half the measure of the minor arc QS.

Therefore, if m∠QRS = 46, then m(arc QS) = 2×m∠QRS = 2×46 = 92 degrees.

Since the measure of an arc is equal to the measure of the central angle that intercepts it, and the sum of the measures of the central angles in a circle is 360 degrees, we have:

m(arc QS) + m(arc QR) = 360 degrees

Substituting the value of m(arc QS) that we found above, we get:

92 degrees + m(arc QR) = 360 degrees

Solving for m(arc QR), we get:

m(arc QR) = 360 degrees - 92 degrees = 268 degrees

Since QS is a minor arc of the circle, the measure of angle QQS is equal to half the measure of the arc QS. Therefore, we have:

m∠QQS = 0.5×m(arc QS) = 0.5×92 = 46 degrees

Therefore, the angle measure of minor arc QS is 92 degrees, and the angle measure of angle QQS is 46 degrees.

The value of the car after 7 years is approximately $18,994.7.

A linear equation is defined as an equation in which the highest power of the variable is always one.

Let V be the value of the car after 7 years.

In the first year, the value of the car depreciates by 5%, so the value after the first year is:

V1 = 0.95 × 27,200

In the second year, the value of the car depreciates again by 5%, so the value after the second year is:

V2 = 0.95 × V1

Similarly, the value of the car after the third year is:

V3 = 0.95 × V2

We can continue this process for each of the 7 years:

V4 = 0.95 × V3

V5 = 0.95 × V4

V6 = 0.95 × V5

V7 = 0.95 × V6

So, the equation that represents the value of the car after 7 years is:

V = 0.95⁷ × 27,200

What is a system of equations?

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. A set or group of equations that are solved collectively is referred to as a system of equations. Both algebraic and visual solutions are possible for these equations. The intersection of two lines represents the system of equations' solution. A group of equations that are all satisfied by the same set of variables are referred to as a system of linear equations. Finding the value of the variable that makes the condition of all the given equations true is the primary goal when solving an equation system.

1) y = -3 and x = -6

This system of equations has only one solution as the variables have only a constant as their value.

2) y = 2x and y = -2x

3) y = -x -2
