What is isosceles angle theorem?.

Answer:

12 - 3z or 3 .9 - 3z

Step-by-step explanation:

1 - if it is just a "9" and not a "0 .9" the answer is "12-3z". You will have to isolate the expressions with the "z" (the 2z and the z). They have a "-" before them, so they are negative expressions (-2z and -z). When the letter is alone, we supose that is a whole, not a decimal, expression, so it is like "1z". After all, you will have two negative expressions, the "-1z" and the "-2z", then you will just add "-1z" and "-2x" (-1z + (-2z) = -1z -2z = -3z

Now, you will need to add "9" and "+3" (9 + (+3) = 9 + 3 = 12).

Now, you have a "-3z" and the "12", and you will add they (-3z + 12 = 12 + (-3z) = 12 - 3z).

2 - But, if it is a "0 .9" ( "0 .9" is the same of " .9" and not a "9" the answer is "3 .9 - 3z". Now it is the same as the number 1 (just do the same from the "You will have" to the "-1z -2z = -3z".

Now, you need to add "0 .9" and "+3" ( .9 + (+3) = .9 + 3 = 3 .9).

So, you have the "-3z" and the "3 .9", and you need to add them ( 3 .9 + (-3z) = 3 .9 - 3z ).

I recommend you to study more of rule of signs, like (-) + (-) = (+) and things like this.

The strength of an earthquake differ for a 1. 0 increment in the Richter magnitude scale by 31 units.

American seismologists Charles F. Richter and Beno Gutenberg developed the Richter scale (ML), a numerical indicator of an earthquake's size, in 1935. The height of the greatest seismic wave, as measured by the logarithm of its amplitude (height), is used to calculate the earthquake's magnitude.

Although the original Richter scale has been supplanted by other, more precise scales in modern science, the Richter scale is still frequently used incorrectly in news reporting of earthquake severity as a catch-all name for the logarithmic scale that earthquakes are measured on.

The length of TS  in ΔTRS using Similarity of triange is 12 cm .

If two items have the same shape or have the same shape as their mirror images, they are said to be Similar. One can be produced from the other more accurately by evenly scaling it, perhaps with the addition of further translation, rotation, and reflection.

If the sides are in the same ratio or proportion and the angles are equal (corresponding angles), two triangles will be comparable (corresponding sides). Similar triangles may have varying individual side lengths, but they must have equal angles and the same scale factor or matching ratio of the side lengths. If two triangles resemble one another, then

When solving systems of equation with three variables we use the elimination method or the substitution method to make a system of two equations in two variables.

There are several methods to solve a system of equations with three variables, including substitution, elimination, and graphing. One common method is to use elimination, also known as the addition/subtraction method. This involves adding or subtracting equations in order to eliminate one of the variables and creating an equation with only two variables. Once you have a system of two equations with two variables, you can solve for one of the variables, substitute that value back into one of the original equations, and then solve for the remaining variable. After that you can use the value of the variables to find the values of the other variables.

Total thirty-nine months will be take by Johnson family to pay off the balance, $10,000.00.

The monthly payment is the amount paid per month to pay off the principle in the time period of the loan. If your rate is r%, divide r/100 by 12 to calculate your monthly interest rate. Formula for monthly payment is, M = Pr(1+r)ⁿ/{(1+r)ⁿ - 1 }

where, P --> principle

r--> rate of interest in months

n --> number of periods (in months )

In this problem, Johnson family bought the furniture and appliances for a new house that is principle, P = $10,000

Rate of interest, R = 15%

In terms of months, R = 0.15/12

= 0.0125 per month

Monthly payment, M = $325.00

Plugging all known values in above formula we get, $325.00 = {$10,000 × 0.0125(1 + 0.0125)ⁿ}/{(1+ 0.0124)ⁿ - 1 }

=> 325 = 125(1.0125)ⁿ/{(1.0125)ⁿ - 1}

=> 325 {(1.0125)ⁿ - 1} = 125(1.0125)ⁿ

=> 325(1.0125)ⁿ - 325 = 125(1.0125)ⁿ

=> 325(1.0125)ⁿ - 125(1.0125)ⁿ = 325

=> 200 (1.0125)ⁿ = 325

=> (1.0125)ⁿ = 325/200 = 13/8 = 1.6250

Taking natural logarithm both sides

=> ln(1.0125)ⁿ = ln (1.6250)

=> n ln(1.0125) = ln (1.6250) = 0.4855

=> n×0.0124 = 0.4855

=> n = 0.4855/0.0124 = 39.153 ~ 39

The limit is normally defined as

[tex]lim _{x- > c} f(x) = L[/tex]

It is read as “the limit of f of x, as x approaches c equals L”.

In mathematics, limits are the points at which a function approaches the output for the specified input values. Calculus and mathematical analysis depend heavily on limits, which are required to determine integrals, derivatives, and continuity. It is applied during the analysis process and always focuses on the function's behaviour at a certain time. The idea of the limit of a topological net broadens the definition of the limit of a sequence and relates it to the limit and direct limit in the theory category. In general, there are two sorts of integrals: definite integrals and indefinite integrals. The upper limit and lower limit for definite integrals are correctly defined.

Limits in maths are unique real numbers. Let us consider a real-valued function “f” and the real number “c”, the limit is normally defined as

[tex]lim _{x- > c} f(x) = L[/tex]

It is read as “the limit of f of x, as x approaches c equals L”. The “lim” shows the limit, and fact that function f(x) approaches the limit L as x approaches c is described by the right arrow.

A function may get close to two distinct limits. There are two scenarios: one in which the variable approaches its limit by values larger than the limit, and the other by values smaller than the limit. The right and left-hand limits still exist even though the limit is not specified in this situation.

Step-by-step explanation:

so you basically have to find the Least common multiple

The zeros of polynomial function f(x) = x³ - 2x² - 24x are x = 0, x = -4 and x = 6

Consider given function  f(x) = x³ - 2x² - 24x

We know that the zeros of a function are nothing but the values of the variable of the function that makes the function value equal to 0.

To find the zeros of function f(x), we need to equate f(x) to zero then solve it for x.

⇒ f(x) = 0

⇒  x³ - 2x² - 24x = 0

⇒  x (x² - 2x - 24) = 0

⇒ x = 0   OR   x² - 2x - 24 = 0

Now we solve quadratic equation x² - 2x - 24 = 0

x² - 2x - 24 = 0

x² - 6x + 4x - 24 = 0

(x - 6)(x + 4) = 0

x = 6      OR  x = -4

Thus x = 0, x = -4 and x = 6 are zeros of given polynomial function.

Equivalent expression : In Algebra, equivalent expressions are algebraic expressions that, although they look different, turn out to really be the same. And since they are the same, they will produce the same results when same value substitute for their variables. For example, 3(x + 2) and 3x + 6 are equivalent expressions because the value of both expressions remains the same for any value of x. When writing equivalent expressions, we must be sure that each side of the equal number corresponds to the same number. Using the factoring :

The equation for the altitude AR of triangle ABC will be 4y-3x=0 i.e. B.

What is a triangle?

Triangles are polygons in geometry that have three sides and three vertices. This figure is two-dimensional and has three straight sides. A triangle is a three-sided polygon. A triangle's three angles added together equals 180°. A single plane contains the triangle. The triangle is classified into six forms based on its sides and angles.

A triangle is categorized into three categories based on its sides, namely:

Scalene Triangle - Each side has a distinct length.

Isosceles Triangle - A triangle with two sides of equal length and one side of a different length.

Equilateral Triangle - A triangle has three sides that are of the same length.

A triangle is categorized into three categories based on its angles, namely:

Acute Angle Triangle - A triangle with all of its angles smaller than 90°.

Obtuse Angle Triangle - A triangle with one of its angles larger than 90°.

Triangle with a Right Angle - A triangle with one of its angles equal to 90°.

Now,

The general form of the linear line is:

y = mx + c where m is the slope and c is the y-intercept

Step 1: getting the slope:

Since AR is the altitude of ABC, therefore, AR is perpendicular on BC which means that slope of AR = -1/slope of BC

Therefore, we will need to get slope of BC:

We have point B = (0,4) and point C = (3,0)

slope of BC = (y2-y1) / (x2-x1) = (0-4) / (3-0) = -4/3

This means that:

slope of AR = m = 3/4

Step 2: getting the y-intercept:

Since point A belongs to the altitude, therefore, point A satisfies the equation of the line. So, to get the y-intercept, we will use point A to substitute in the equation of the line and solve for c as follows:

y = mx + c

y = (3/4) x + c

0 = (3/4)(0) + c

c = 0

Hence,
