a) The linear function for this problem is defined as follows: y = -0.75x + 20.

b) The time that he worked on Day 0 is given as follows: 20 hours.

c) The daily decrease in the setup time is given as follows: 0.75 hours a day.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

Two points from the graph are given as follows:

(8, 14) and (16,8).

When x increases by 8, y decays by 6, hence the slope m is given as follows:

m = -6/8

m = -0.75.

Hence:

y = -0.75x + b.

When x = 8, y = 14, hence the intercept b is given as follows:

14 = -0.75(8) + b

b = 14 + 0.75(8)

b = 20.

Hence the function is defined as follows:

y = -0.75x + 20.

Answer: a (x – x1) + b (y– y1) + c (z –z1) = 0.

Step-by-step explanation:

Recall that the general form of the equation of a straight line in two dimensions is

++=0.

This can also be written in the form 

=+, where  is the gradient and  is the -intercept, which we can determine by knowing two points on the line.

If (,) is a point that lies on the line, we can determine  from the general form as =−(+); thus, the equation of the line can be written as

+−(+)=0.

The equation of the line can also be realized as a dot product of two vectors as (,)⋅(−,−)=0.

Now, if we define the position vectors,⃑=(,),⃑

then the equation of the line can be written in vector form as⃑ ⋅⃑=⃑⋅⃑,where ⃑=(,) is called a normal vector of the line and ⃑−⃑ will lie completely on the line.

A property of the dot product states that two vectors are perpendicular to each other if their dot product is zero. This equation of the line in vector form shows that the normal vector ⃑ and the vector ⃑−⃑ are perpendicular to each other by this property.

The general equation of a plane in three-dimensional space can be represented as Ax + By + Cz = D.

What is the plane?

A plane is a two-dimensional doubly ruled surface spanned by two linearly independent vectors. The generalization of the plane to higher dimensions is called a hyperplane. The angle between two intersecting planes is known as the dihedral angle.

Where A, B, and C are coefficients and D is a constant.

The coefficients A, B, and C represent the components of the normal vector to the plane, and D represents the distance of the plane from the origin.

The equation defines a set of all points (x, y, z) in space that satisfy the equation and lie on the plane.

Hence, The general equation of a plane in three-dimensional space can be represented as Ax + By + Cz = D.

There are an infinite number of planes that are orthogonal to a given plane in space, and this is due to the fact that a plane can be thought of as a flat surface that extends indefinitely in all directions.

Orthogonal Planes in Space: In three-dimensional space, a plane is said to be orthogonal to another plane if the two planes are perpendicular to each other, i.e., their normal vectors are perpendicular. Since the normal vectors of two orthogonal planes are perpendicular to each other, this means that the angle between them is equal to 90 degrees.

the sum of the last 3 integers is 3 more than the sum of the 2 greatest :

x+4 + x+6 + x+8 = x+6 + x+8 + 3

The solution to the division problem is xyz = −434 with a remainder of 0.

The given equation is [tex]$\frac{4-4-40-1-100-1}{xyz} = -434$[/tex]. To solve this equation, we need to find the value of [tex]$xyz$[/tex]. We can use the distributive property to break up the numerator, yielding [tex]$\frac{(-1)(-100)(-1)}{xyz} = -434$[/tex]. Then, we can multiply both sides by [tex]$xyz$[/tex] to get [tex]$(-1)(-100)(-1)xyz = -434xyz$[/tex] . Since the terms on both sides of the equation are equal, we can simplify to [tex]$(-1)(-1)(-100)xyz = -434xyz$[/tex] . Now, we can factor out the xyz, which yields  [tex]$xyz(-1)(-1)(-100) = -434xyz$[/tex]. Since we want to find the value of xyz, we can divide both sides by the common factor of xyz, yielding [tex]$(-1)(-1)(-100) = -434$[/tex] .

In set theory, the set of all subsets of a Set A, including the Set itself and the null or empty set, is referred to as the power set (or power set). The Power Set of the given set will consist of 2n elements if the given set has n elements. It also symbolizes the power set's cardinality.

A population's per capita growth rate changes—typically declines—with rising population density due to density-dependent limiting constraints. One illustration is how individuals in a group compete for scarce food.

Independent of population density, several factors impact the per capita growth rate. Natural catastrophes like forest fires are examples.

According to the data problem,

The cost of computer = $ 800

It lost 1/5 of value every year.

The value of computer after 0 years = cost of computer = $ 800

The value after 1 year = 800 - (1/5*800) = $640

The value after 2 years = 640 - (1/5*640) = $512

The value after 3 years = 512- (1/5*512) = $409.6

Continue with the formula we have:

The value after 9 years = 134.21 - (1/5*134.21) = 107.37

The value after 10 years = 107.37 - (1/5*107.37) = 85.90

The value after n years = computer cost at (n-1) year - 1/5 (n-1cost)
