What is an isosceles triangle ??

In geometry, an isosceles triangle is one with at least two equal-length sides. Both having exactly two sides of equal length and having at least two sides of equal length are valid requirements; the equilateral triangle is an exception to the second criteria. Isosceles triangles can be found in several Catalan solids, bipyramid faces, the golden triangle, the isosceles right triangle, and many other geometrical structures.

Given that the triangle's two sides are equal in this illustration, it is an isosceles triangle.

In the given ΔABC,

given ΔDFE ≅ ΔCFB

x= 45*2.5 = 112.5

z = 112.5-60= 52.5

Hence the value of side z is 52.5.

Answer: 17

Step-by-step explanation:)

The X intercept of H(x) is x=8, and the multiplicity is 2. The graph bounces off the X axis at x=8.

The X intercept of a polynomial function is the point where the graph of the function crosses the X axis. The multiplicity of an X intercept is the number of times the graph of the function crosses the X axis at that point.

In this case, the X intercept is x=8, and the multiplicity is 2. This means that the graph of the function crosses the X axis twice at x=8. The first time it crosses, it will bounce off the X axis. The second time it crosses, it will bounce off the X axis again.

Answer:

5.3

Step-by-step explanation:

Since they are similar triangles, we assume the ratio between AM/AN is equal to the ratio between MB/NC.
AM/AN = 6/8 = 3/4
If MB is 4
3/4 = MB/NC = 4/NC
3/4 = 4/NC

3NC = 16
NC = 16/3
16/3 = 5.333333

x+3=4 is the the algebraic expression.

An equation is one that is comprised of integer constants, variables, and algebraic operations. Algebraic expressions include, for instance, 3x2 2xy + c. Monomial expressions are one of the three primary categories of algebraic expressions. Binomial Expression. Polynomial Expression. An algebraic expression is a mathematical sentence that makes use of coefficients, unknowable variables, algebraic operations, and constants. However, an expression cannot contain an equals sign. Algebraic expressions must have at least one variable and one operation (addition, subtraction, multiplication, division). An algebraic expression is one that contains one or more variables. For instance, the expression 2(x + 8y) is an algebraic expression.

Answer:

C.    Student C, who is paid $290 for 20 hours of work

Step-by-step explanation:

What we know:

    - Student A ( 164.50 = 14 hours )

    - Student B ( 162.00 = 12 hours

    - Student C ( 14.50h = p )

What we need to figure out:

    - How much each person makes per hour ( Pt.1 )

    - Who will make the most in 20 hours ( Pt.2 )

How to execute:

    - Divide for A & B

    - Convert for C

    - Multiply for all

Step 1: Divide the total pay by the hours for A & B

Student A:   164.50 ÷ 14 = 11.75 per hour ( Found PT.1 )

Student B:    162.00 ÷ 12 = 13.50 per hour ( Found PT.1 )

Step 2: Convert C so that it looks like A & B

Student C:    14.5(h) = p  --->   p ÷ h =   14.5 per hour ( Found PT.1 )

Step 3: Multiply the hourly rate by the 20 hours

Student A:   11.75 × 20 = 235 for 20 hours      ( Found PT.2 )

Student B:   13.50 × 20 = 270 for 20 hours     ( Found PT.2 )

Student C:   14.50 × 20 = 290 for 20 hours     ( Found PT.2 )

Answer: look you need to count or multiply a number by

Step-by-step explanation:

The increasing exponential functions are described as follows:

f(t) = a(1 + r)^t.

In which the parameters are listed as follows:

For the old factory, the function is of:

p (w) = 230(1.1)^w.

Hence:

For the new factory, from the graph given at the end of the answer, the parameters are given as follows:

Hence the function is:

pn(w) = 190(1.1578)^w.

The new factory overtakes the old factory when:

pn(w) > p(w)

190(1.1578)^w > 230(1.1)^w

(1.1578/1.1)^w > 230/190

wlog(1.1578/1.1) > log(230/190)

w > log(230/190)/log(1.1578/1.1)

w > 3.73 weeks.

Equating Y from both equations, we get,325.0454 - 0.5r + 4.851e = 400 + 400rSolving the above equation for r, we get r = 0.1089 or 10.89%..

The first term and the last term in the arithmetic progression are -2.5 and 22.5 respectively.

In Mathematics, the sum of a geometric sequence is given by this mathematical expression:

\(S=\frac{a_1(1-r^n)}{1-r}\)

Where:

Mathematically, the sum of an arithmetic sequence is calculated by using this expression:

Sn = n/2(2a₁ + (n - 1)d)

Where:

Since the sum of all the terms in the geometric progression is equal to the sum of all the terms in the arithmetic progression, we have:

256(1 - 0.5^8)/(1 - 0.5) = 51/2(2a₁ + (51 - 1)0.5)

256(1 - 0.00390625)/(0.5) = 25.5(2a₁ + 25)

255/0.5 = 51a₁ + 637.5

510 = 51a₁ + 637.5

51a₁ = -127.5

a₁ = -2.5

For the last term, we would use the following formula:

aₙ =  a₁ + (n - 1)d

a₅₁ =  -2.5 + (51 - 1)4

a₅₁ =  -2.5 + (50)0.5

a₅₁ = 22.5.

True. total count and total duration ioas are less precise measures than mean count and mean duration per occurrence data.

Total count and total duration IOAs (Interval Observation Agreements) are less precise measures than mean count and mean duration per occurrence data. This is because total count and duration do not take into account the frequency or duration of individual occurrences, leading to less detailed and less accurate information about the behavior being observed. Mean count and duration per occurrence provide more precise and accurate measures because they take into account the frequency and duration of individual occurrences, providing a more detailed and complete understanding of the behavior being observed. Therefore, mean count and duration per occurrence are generally considered to be more reliable and informative measures than total count and duration IOAs.

What is a function?

A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.

The functions of a point (or vector) in R2 or R3 that have real values will now be looked at. These functions will typically be defined on sets of points in R2, but there will be occasions when we utilise points in R3 and when it is more convenient to think of the points as vectors (or terminal points of vectors).

Each point f(x,y) in D is given a real number f(x,y) according to a real-valued function f defined on a subset D of R2. The domain of f is the set of all real numbers f(x,y) as (x,y) varies throughout the domain D, and the range of f is the greatest set D in R2 on which f is defined.

Answer: The answer is A, L (9,0) and scale factor is 3.

Answer: The two consecutive integers are 36 and 37.

Step-by-step explanation: Let's call the smaller integer "x".

According to the problem, the larger integer is the next consecutive integer, so we can call it "x + 1".

The problem tells us that the sum of the larger integer and 23 less than the smaller integer is 50. So we can set up the equation:

(x + 1) + (x - 23) = 50

Simplifying the equation, we get:

2x - 22 = 50

Adding 22 to both sides, we get:

2x = 72

Dividing both sides by 2, we get:

x = 36

So the smaller integer is 36. The next consecutive integer is 37.

Therefore, the two consecutive integers are 36 and 37.

We can see that that the size of the hypotenuse is 20.

A perfect 90-degree angle (a right angle) distinguishes a right triangle from other triangle types. The junction of the triangle's two perpendicular sides results in the formation of this angle.
