In order to prove that ∠E = ∠I, we can use the following statements and reasons:

1. Statement: ∠E = ∠FGL

Reason: Opposite angles in a parallelogram are congruent

2. Statement: ∠FGL = ∠KLG

Reason: Alternate interior angles

3. Statement: ∠KLG = ∠I

Reason: Opposite angles in a parallelogram are congruent

4. Statement: ∠E = ∠I

Reason: Transitive property of the equality (∠E = ∠FGL, ∠FGL = ∠KLG and ∠KLG = ∠I, so ∠E = ∠I)

The standard unemployment rate is of 0.0794 = 7.94%.

Step-by-step explanation:

The standard unemployment rate, as a proportion, is the number of unemployed people divided by the size of the labor force.

In this question:

Labor force: 189 million

Number of unemployed people: 15 million

What is the standard unemployment rate?

15/189 = 0.0794

Step-by-step explanation:

Since jane weighs 126 and is gaining 3 pounds per month that would make the part of the equation that is 126+3m and since Cynthia weighs 134 and is gaining 2 pounds every month that is what makes the 134+2m part of the equation. And since the equation is 134+2m=126+3m then the goal is to find how many months it would take for their weights' to be equal.

The values of the variables in the circles are

From the question, we have the following parameters that can be used in our computation:

Circles and missing angles (see attachment for the figures)

Circle 1

To determine the unknown variable (a), we make use of the following theorem

The angle subtended by an arc at the circumference is twice the angle subtended at the circumference

Mathematically, this means that

a = 2 * 17 degrees

Evaluate the product

a = 34 degrees

Circle 2

To determine the unknown variable (a), we make use of the following theorem

The angle at the circumference in a semicircle is 90 degrees.

Mathematically, this means that

b = 90 degrees

Also, we have

a + 122 degrees = 180 degrees

Evaluate

a = 58 degrees

Using the theorem in (a), we have

b + a/2 + c = 180

This gives

90 + 58/2 + c = 180

Evaluate the like terms

c = 61 degrees

Hence, the angle c is 61 degrees

Answer:

To find the rules for (fg)(x) and (gf)(x), we need to evaluate the composite functions.

(fg)(x) = f(g(x)) = f(sqrt(x - 5)) = (sqrt(x - 5))^2 + 5 = x - 5 + 5 = x

(gf)(x) = g(f(x)) = g(x^2 + 5) = sqrt(x^2 + 5 - 5) = sqrt(x^2) = |x|

Therefore, the rules for (fg)(x) and (gf)(x) are:

(fg)(x) = x

(gf)(x) = |x|

The value of x is 14 units.

When handling and dealing with difficulties involving the measurement of length and angles of a right-angled triangle, trigonometric values of ratios such as sine, cos, tan, cosec, cot, and secant come in handy. The trigonometric function is widely used to solve trigonometric issues at 0°, 30°, 45°, 60°, and 90°.

We know for angle of 30° the base is 7 and perpendicular is x

then

sin30° = 7/x

      \(\frac{1}{2} =\frac{7}{x}\)

       x = 7

hence, the value of x = 14 units

1. Event A includes the outcomes of H and T,

2. while event AC includes all the possible outcomes of rolling a number cube, which are 1, 2, 3, 4, 5, and 6.

1. Event A is defined as tossing a heads on a coin, regardless of the outcome of rolling a number cube. Therefore, the outcomes in event A are H (heads) and T (tails), since either of these outcomes could occur when rolling a number cube and tossing a coin.

2. Event AC is the complement of event A, i.e., it is the set of outcomes that are not in event A. Since event A contains H and T, the outcomes in event AC are the remaining outcomes that are not in event A, which are all the possible outcomes when rolling a number cube: 1, 2, 3, 4, 5, and 6.

Answer:

B. 576√3

Step-by-step explanation:

Remember your 30 60 90 triangle rules. The hypotenuse is 2x, the 90 degree  side is x√3 and the last side is x.

Step 1: 30 60 90

48 = 2x

x = 24

The height will be 24√3 and the base (Line JMK) will be 48 (because 24 times 2, 2 triangles present). Then use area formula A = 1/2bh

Step 2:

A = 1/2(24√3)(48)

A = 576√3

There are number of thesis that are given for mathematics by various professors and scientists at various levels that are being implemented from time to time.

A theory is nothing but a set of statements which may be based on certain principles that might have been derived by performing some experiments and attaining a proper conclusion. For example, if we say 'the sky is blue'. It means this truth can never be changed irrespective of the situations. This will remain mortal.

Similarly, there are plenty of terms in mathematics such as decimals, percentage, geometry, algebra and more fundamentals. These are existing since ages and have been challenged also. But the theory remains the same. There operas-memoranda remains the same. So various scholars, have given various theories of mathematics.

Step-by-step explanation:

Given the question above :

The probability distribution :

X : ___ 1 ___ 2 ___ 3 ___ 4 ____ 5

P(x): _ 0.1 __ 0.1 __ 0.6 _ 0.1 __ 0.1

The Variance : Var(X) = (Σx²*p(x)) - μ²

μ = E(X) = Σ(X * p(x)) :

Σ(X * p(x)) = (1*0.1)+(2*0.1)+(3*0.6)+(4*0.1)+(5*0.1)

μ = 3

Var(X): [(1^2*0.1)+(2^2*0.1)+(3^2*0.6)+(4^2*0.1)+(5^2*0.1)] - 3²

= 10 - 9

= 1

Hence. Variance = 1

The resulting differential function is f'(x) = 2x and g'(x) = 2x² + 1

The term function in statistics refers the expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Here we have given that let f and g be functions that are differentiable for all real numbers.

And we have to find the solution for the function.

Let us consider f(x) =  x² and g(x) = x³ + 1

Then the differentiation function is calculated as,

As per the law of differentiation, it can be written like the following,

=> f'(x) = x² dx

Then it can be written as the following after differentiation

=> f'(x) = 2x

Similarly, the g(x) is differentiated like the following,

=> g'(x) = x³ + 1 dx

=> g'(x) = 2x² + 1

Answer:

\(3x^3(x-1)(2x^3+2x^2+2x+3)\)

Step-by-step explanation:

We can start by factoring out x³ because it's the greatest factor of every term:

\(6x^7+3x^4-9x^3=x^3(6x^4+3x-9)\)

Next, notice that each coefficient is divisible by 3, so this can be factored out as well:

\(x^3(6x^4+3x-9)=3x^3(2x^4+x-3)\)

While it may not look like we can factor out 2x⁴+x-3, we actually can! Notice the following:

\(2x^4+x-3=(2x^4+2x^3+2x^2+3x)+(-2x^3-2x^2-2x-3)=x(2x^3+2x^2+2x+3)-1(2x^3-2x^2+2x+3)=(x-1)(2x^3+2x^2+2x+3)\)

By grouping, we were able to condense this factor. Thus:

\(6x^7+3x^4-9x^3=\bf{3x^3(x-1)(2x^3+2x^2+2x+3)}\)
