In circle F, m/GFH = 140° and the area of the shaded sector = 14π. Find the length of FG.

In Circle F, M/GFH = 140 And The Area Of The Shaded Sector = 14. Find The Length Of FG.

Answers

Answer 1

The length of FG = (7/18) x 2π(√(28π))/(√140).

What is length?

Length is a measurement of a distance, size, or quantity. It is usually measured in units such as meters, feet, or miles, but can also refer to an amount of time. Length is a fundamental concept in mathematics and is used for a variety of purposes in the natural and social sciences. In physics, length is related to energy, momentum, and the speed of light. In geometry, length is a measure of the distance between two points on a line or plane. Length also plays an important role in everyday life, from measuring the size of a room to calculating the time it takes to get from one place to another.

Let G be the center of the circle and the radius be ‘r’.

The arc length FG = (140/360) x 2πr = (7/18) x 2πr

Area of sector = (1/2) x r² x θ = 14π

Therefore, r² θ = 28π

Therefore, r² = (28π)/θ

Substituting the value of θ = 140° in the above equation,

r² = (28π)/140

Therefore, radius, r = (√(28π))/(√140)

Therefore, length of FG = (7/18) x 2πr = (7/18) x 2π(√(28π))/(√140)

Hence, the length of FG = (7/18) x 2π(√(28π))/(√140).

solve the following simultaneous equations

Answers

The equation y = 3x - 1 and x² + y² = 73 then x = -1, y = -2.

What is meant by Simultaneous equations?

Simultaneous linear equations are a pair of linear equations in two or three variables that are solved simultaneously to arrive at a single answer.

Simultaneous equations are two or more algebraic equations that share the same unknown variables and have the same solution for each of them. The simultaneous equations must therefore have a single solution, according to this.

Add together the equations if the signs vary. Subtract the indications from one another if they match. Different Add, Same Subtract, or DASS, is a simple way to remember this.

Substitute y = 3x + 1 in [tex]$x^2+y^2=5$[/tex]

[tex]$$x^2+(3 x+1)^2=5 \quad \Rightarrow \quad 10 x^2+6 x-4=0$$[/tex]

Hence

[tex]$$\begin{aligned}& 5 x^2+3 x-2=0 \Rightarrow 5 x^2+5 x-2 x-2=0 \quad \\\& 5 x(x+1)-2(x+1)=0 \quad \Rightarrow \quad(5 x-2)(x+1)=0\end{aligned}$$[/tex]

Hence, either [tex]$x=\frac{2}{5}, y=3 \times \frac{2}{5}+1=\frac{11}{5}$[/tex]

or [tex]$x=-1, y=3 \times(-1)+1=-2$[/tex].

Why do we use log function?

Answers

Logarithmic functions are important largely because of their relationship to exponential functions.

What is logarithm ?

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a number x to the base b is the exponent to which b must be raised, to produce x. For example, since 1000 = 10³, the logarithm base 10 of 1000 is 3, or log₁₀ = 3.

The first section explains the meaning of the logarithmic function f (x) = c·loga(x - h) + k. It describes how to evaluate logarithms and how to graph logarithmic functions. This section also addresses the domain and range of a logarithmic function, which are inverses of those of its corresponding exponential function.

The next section presents two special logarithmic functions--the common logarithmic function and the natural logarithmic function. The common logarithm is log10x, and it corresponds to the "log" button on most calculators. The natural logarithm is logex, and it corresponds to the "ln" button on most calculators. The natural log has a particular use in economics--it is used to perform calculations involving compound interest.

How to calculate the slope of a line?

In Mathematics, the slope of a straight line can be calculated by using this this mathematical expression;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

From the information provided above, we have the following slope and data points on the line:

Points on x-axis = (1, 2).

Points on y-axis = (_, 8).

Slope, m = 3/2

Substituting the given points into the slope formula, we have the following;

Slope, m = (y₂ - y₁)/(x₂ - x₁)

3/2 = (8 - 2)/(x₂ - 1)

3/2 = 6/(x₂ - 1)

Cross-multiplying, we have:

3(x₂ - 1) = 12

x₂ - 1 = 12/3

x₂ - 1 = 4

x₂ = 4 + 1

x₂ = 5

In conclusion, we can logically deduce that the second point (x₂) is 5.

What are the steps to determining a graph's parent function and transformation?

By modifying the value of x (for example, y(x) = x + 2) or by multiplying x by a constant (for example, y(x) = 3x), you can examine the graphs of linear functions. Do not forget that y(x) = x is the linear parent function. Its most fundamental and straightforward form is this.

The graph of y = f (x - h) is translated h units to the RIGHT of the graph of the parent function if h > 0, and it is translated h units to the LEFT if h 0.

as in f(x) = ( x – 3)

The graph of y=f(x-h) is a translation of |h| units to the LEFT of the graph of the parent function if h 0; otherwise, it is a straight line.

What is that opinion? 6. You are constructing a 90% confidence interval for a sample consisting of n = 9 values and anunknown population standard deviation. The population appears to be very skewed. Determinewhether a margin of error should be calculated using a critical value of za/2, a critical value of ta/2, or neither. a) a critical value of za/2b) a critical value of ta/2c) neither7. The standard deviation of sample size of n = 15 is 345 and the mean is 6784. Given that the population follows a normal distribution, construct a 90% confidence interval estimate of the mean of the population. a) 6519 b) 6593c) 6627 d)6783
