A function exists described as a relation between a set of inputs containing one output each. The value of h(g(3)) is 5.

A relationship between a group of inputs and one output is referred to as a function.

In plain English, a function is an association between inputs in which each input is connected to precisely one output.

A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Where, g(3) = 0

To get h, replace g(3) with 0 in the requested equation (0).

Since h(0) = 5 according to the question, your final response is 5.

Therefore, the value of h(g(3)) is 5.

We can find the distance between the points X and Y by using distance formula.

The distance formula is used to find the distance between two defined points on a graph (in the absence of a scale).

Here the two points are  X(-2,5) and Y(1,11).

The distance formula for points (a,b) and (c,d) is given by :-[tex]\sqrt{(d-b)^2+(c-a)^2}[/tex]

Here,

(a,b) represents the point X(-2,5), and

(c,d) represents the point Y(1,11)

Answer:

Step-by-step explanation:

to find the y intercept of AB, first find the slope of AB: m=(1-(-1))/(2-14)=-1/6

the equation of line AB is y=-(1/6)x+b

use either of the given two points to find out b: 1=(-1/6)*2+b => b=4/3

BC is perpendicular to AB, so the slope of BC is the negative reciprocal of the slope of AB, therefore, the slope of BC is 6

Equation of BC is y=6x+b

find out b by using the coordinates of point B: 1=6*2+b => b=-11

the equation of BC is: y=6x-11

the x coordinate of point C: 13=6*x -11 =>x=4

The geometric mean can be determined by multiplying the terms from part c and the first term of the sequence from part a and taking their square root.

The first term of the sequence from part a is 2 and the term from part c is 512.

Geometric mean of a sequence is the average value of a set of numbers, determined by multiplying the terms together and taking their root.

In general form, the geometric mean for a n number of terms is n√x1*x2*x3*…*xn

Since there are two terms 2 and 512, we will take the square root of the product.

Geometric mean=√2*512=√1024=32

For the geometric sequence as it is the mean, the term will be the 2nd term of the sequence

Hence, the geometric mean of the two chosen positive number 2 and 512 is 32 which is the 2nd term.

Considering the expression of a line and how to obtain it having 2 points, you obtain:

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x1, y1) and (x2, y2) of a line, the slope m of said line can be calculated using the following expression:

m= (y2 - y1)÷ (x2 - x1)

Substituting the value of the slope m and the value of one of the points in the expression of a linear equation, y = mx + b, the value of the ordinate to the origin b can be obtained.

In this case, you want to obtaina linear equation giving the sales y in terms of the year x. You know:

So, being (x1,y1)= (2011, 32.266) and (x2,y2)= (2012, 33.278), the slope m can be calculated as:

m= (33.278 - 32.266)÷ (2012 - 2011)

Solving:

m=1.012

Considering point 1 and the slope m, you obtain:

32.266= 1.012×2011 + b

32.266= 2035.132 + b

32.266- 2035.132= b

- 2002.866= b

Finally, the linear equation giving the sales y in terms of the year x is y=1.012x - 2002.866

You can use the equation to predict the sales for 2013 as follow:

y=1.012×2013 - 2002.866

Solving:

y=1.012×2013 - 2002.866

y= $34.29 billion

Finally, the sales in 2013 will be $34.29 billion.

An infinite geometric series is the outcome of an unlimited geometric sequence.

The infinite geometric series be 2/5 +4/25 + 8/125 + . . . . then the sum of the infinite geometric series is 2/3.

An infinite geometric series is the outcome of an unlimited geometric sequence. This series wouldn't have a finish. It is possible to calculate the sum of all finite geometric series. The terms in the sequence will grow steadily larger, but adding the larger numbers together will not provide a solution if the common ratio of an infinite geometric series is greater than one.

Given:

a(first term) = 2/5

r(common difference) = 2/5

Since, |r| < 1 the infinite series converges.

[tex]S_\infty[/tex] = a/1-r ; -1 < r < 1

[tex]S_\infty[/tex] = (2/5)/(1-2/5)

simplifying the above equation, we get

[tex]S_\infty[/tex] = (2/5)/(3/5) = 2/3

The sum of the infinite geometric series is 2/3.

The equation in the form ax+ by=c a>0 where a and b are not both zero and a, b, and c are integers with greatest common actor  of 1 represent either linear or non linear function. Hence, this statement is true.

The formula for a linear function is f(x) = mx + b, where m and b are real values. Isn't it resembling the slope-intercept form of a line, represented by the equation y = mx + b? Yes, this is the case as the graph of a linear function is a line.

Here,

• 'm' is the slope of the line.

• 'b' is the y-intercept of  line.

• 'x' is the independent variable.

• 'y'  is the dependent variable.

As the name suggests, a nonlinear function is one that is NOT linear. To put it another way, a nonlinear function's graph is not a line, which means that its graph can be anything other than a line.

Given that, ax+ by=c a>0 where a and b are not both zero and a, b, and c are integers with a greatest common factor of 1

ax+ by -c=0     [by transpose]

The general form of linear equation is ax+ by +c z +d=0

Answer: 36 feet of wood

Step-by-step explanation:

P=perimeter. P=total length of wood

s= side length. A=area

A=s^2

81=s^2

s^2=9^2

s=9

P=4s

P=4(9)

P=36 feet of wood

Answer:

P = 36 ft

Step-by-step explanation:

The given length is,

→ a = ?

Formula we use,

→ A = a²

Now the length of one side is,

→ A = a²

→ a² = 81

→ a = √81

→ [ a = 9 ]

The total length of wood needed is,
