(6) In a triangle ABC ,AB = (x +1) cm, AC = x cm and angle BAC =30°. If the area of triangle ABC=18 cm². Draw the figure and find the value of x.​

Answer:  x  ≤ 4.5

Step-by-step explanation:

Since there is a closed circle on 4.5 and the ray is going left we know that x is ≤ 4.5

The side of square is (B) 5.7m

We are given the formula relating side and area of square. Using the mentioned formula to find the value of side of square.

Side² = Area

Rewriting the equation according to side of the square -

Side = √Area

Keep the values in formula to find the value of side of square

Side = √32

Finding square root of the number to find the value of side of square

Side = √(8×4)

Side = √(4×2×4)

Side = 4√2

Side = 4×1.414

Performing multiplication  to find the value of side of square

Side = 5.66

Side = 5.7 meters

Hence, the side of square is (B) 5.7m

The fact that $45 is enough to make bracelets for 10.44 persons means that the we can make bracelets for 10 friends

What is the total necklace cost function?

The total cost of necklaces that can be made within the total budget of $45 can be modeled using a straight-line equation, which considers the fixed cost of necklace supplies of $21.50 and the total variable cost of supplies, the cost per necklace multiplied by the total number of necklaces possible, defined as x

45=21.50+2.25x

let solve for x to determine whether we can make bracelets for 10 friends

45-21.50=2.25x

The constant term of this polynomial function with real coefficients will be - 240.

We are given the zeroes of the equation as:

16 and 1 - 2i

Now, we know that, the imaginary root are always in a pair, so the third root will be:

1 + 2i

This means that the factors of the cubic polynomial will be:

(x - 16)

(x - [1 - 2i])

(x - [1 + 2i])

The leading coefficient is 3, so the polynomial function will be:

y = 3 (x - 16) (x - [1 - 2i]) (x - [1 + 2i])

Now, the constant term will be:

3 (- 16) (1 + 2i) (1 - 2i)

( - 48) (1 - 4i²)

= ( - 48) (5)

= - 240

Therefore, the constant term of this polynomial function with real coefficients will be - 240.

Solution of exponential equation is ,  x = 10

In, mathematics a exponential equation or exponential function is inverse of logarithmic function. That means, we can easily convert the logarithmic function into exponential function and vice versa. The basic form of the logarithm function can be written as  [tex]a^x[/tex] .

where, a is the base of function

           x defines  expression

Mathematically, if  [tex]log_aN = x[/tex] is an logarithmic function then, this can be converted to exponential function as  [tex]a^x = N[/tex].

There are many formulas that are given to us for solving several simple and complex problems based on exponential functions and exponential equations.

Some important formulas of exponential :

According to given statement,

5.2³ x =400

Inequality is a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

The given inequality is 11(3 - x) < -2x + 6

We need to separate the variable x.

11(3 - x) < -2x + 6

33-11x<-2x+6

Let us shift -2x from RHS to LHS and 33 from LHS to RHS

2x-11x<6-33

The measured angle ABD=24° and ABC=71°

The figure in the question is either a triangle or a quadrilateral, but this has not been stated. It is possible to solve this regardless of shape. The accompanying graphic shows the two potential shapes and angles.

Now, based on the information provided, we may deduce that line BD divides angle ABC into two parts: Angle ABC is equal to angle ABD plus angle DBC.

Additionally, we know that angle DBC is 47 degrees and angle ABC is 1 degree less than 3 times angle ABD.

Angle ABC Equals 3x-1 if angle ABD is x.

Angle ABC also equals Angle ABD plus Angle DBC.

Changing the values in the equations above 3x-1 = x+47 ⇒ 2x = 48⇒ x = 24

Angle ABD thus equals 24 degree, and angle ABC = 3(24)-1 = 71-1 = 71 degree

∴∠ABD=24° and ∠ABC=71°

We've all heard the term "exponential." What does that word mean? Exponential means growing faster and faster. However, in mathematics, it represents a formula with one or more exponents. So, we know it as exponential form. I would say that things can grow exponentially as the items being talked about get bigger and faster and faster.

So, we use the following method to write the given expression in exponential.

Expression 1 = ⁴√x³

Expression 2 = ⁵√y⁴

The slope of the line is 1 / 3

The slope of a line is a measure of its steepness.

The slope of the line is the ratio of the rise to the run, or rise divided by the run.

Mathematically, the slope of a line can be described as follows;

slope = change in y / change in x

Therefore,

slope = y₂ - y₁ / x₂ - x₁

Let's take two points from the graph

(0, 2)(3, 3)

where

x₁ = 0

x₂ = 3

y₁ = 2

y₂ = 3

Hence,

slope = 3 - 2 / 3 - 0

slope = 1 / 3
