The desired linear functions are given as follows:

a) x = a.

b) y = b.

A linear function is modeled by:

y = mx + b

In which:

A vertical line has undetermined slope, hence it is defined by x = a, containing point (a,b).

A horizontal line has slope of 0, hence it is defined by y = b, containing point (a,b).

Answer:

  y = (x +1)(x -3)

Step-by-step explanation:

You want the equation in factored form for the parabola shown in the graph with x-intercepts at -1 and +3, and a vertical scale factor of 1.

If p is a zero (x-intercept) of the graphed polynomial function, then (x-p) is a factor. The graph shows x-intercepts at x=-1 and x=3. This means (x-(-1)) and (x -3) are factors.

The equation of the graph may also have a vertical scale factor. That can often be determined easily from the graph by looking at the vertical distance from the vertex of points 1 unit either side of the vertex.

Here, the vertex is (1, -4) and points at x=0 and x=2 have the value -3, which differs from the vertex by 1 unit. Hence the scale factor is 1. It multiplies the other factors.

The equation of the graphed parabola is ...

  y = (x +1)(x -3)

Answer:

If the distance from the origin to a given point is 5, then that point lies on circle C is true.

Step-by-step explanation:

The correct statement about given circle is "If the distance from the origin to a given point is 5, then that point lies on circle C"

In mathematics, the circle is a two dimensional rounded figure which has no corner edges.

Standard form = (x - a)² + (y - b)² = r²

Given that,

The center of a circle is on origin and the radius is 5 unit.

And point p lies on the circle,

So, according to definition of circle the distance  between center and any point on the circle is always constant and which is known as radius.

Therefore, the distance between center end given point will be equal to 5 then it will lies on a circle.

The x-coordinate of the point which divide the line segment is 3.

Given the coordinates in the figure are J(1,-10) and K(9,2) and the 1:3 is the ratio in which the line segment is divided.

When the ratio of the length of a point from both line segments is m:n, the Sectional Formula can be used to get the coordinate of a point that is outside the line.

To find the x-coordinate we will use the formula x=(m/(m+n))(x₂-x₁)+x₁.

Here, m:n=1:3 and x₁=1 from the point J(1,-10) and x₂=9 from the point K(9,2).

Now, we will substitute these values in the formula, we get

x=(1/(1+3))(9-1)+1

x=(1/4)(8)+(1)

x=8/4+1

x=3

Hence, the x-coordinate of the point that divides the directed line segment from k to j into a ratio of 1:3 is 3 units.

The volume of a cylinder changes when you adjust the height or radius as the volume either increases or reduces.

Let's assume that the height and radius are 14cm and 7cm. The volume will be:

= πr²h

= 3.14 × 7² × 14

= 2154.04cm³

When the radius and height are reduced to 5cm and 9cm, the volume will be:

The correct option is D, The relationship is not proportional because the ratio of pages to days is not constant.

A linear relationship is a relationship in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c.

A linear relationship with two variables, when graphed on the cartesian plane with axes of those variables, gives a straight line.

For the given relationship to be proportional, the number of pages read should be the same every day. Therefore, the ratio of the number of pages to the number of days should be equal.

85/1 = 85

170/2 = 85

249/3 = 83

Answer:

g(x)⁻¹ = √x + 3

Step-by-step explanation:

To find the inverse of an expression is to reverse the expression. This can be done by swapping the input and output variables. In other words, in g(x), you want to swap the places of the "x" variable the "y" variable.

Remember, g(x) = y.

y = (x - 3)²                              <----- Original function

x = (y - 3)²                              <----- Swap the variables

Now, you want to set the equation equal to "y" again. This can be done by rearranging/simplifying the expression.

x = (y - 3)²                              <----- Swapped variables

√x = √(y - 3)²                        <----- Take the square root of both sides

√x = y - 3                              <----- Eliminate parentheses from previous step

√x + 3 = y                             <----- Add 3 to both sides

If g(x)⁻¹ represents the inverse of g(x), the new function is:

g(x)⁻¹ = √x + 3

The first few terms of a geometric sequence with first term [tex]a[/tex] and common ratio [tex]r[/tex] look like

[tex]a, ar , ar^2, ar^3, \ldots[/tex]

and so on. Notice that the [tex]n[/tex]-th term (where [tex]n[/tex] is a natural number) is [tex]ar^{n-1}[/tex].

For this particular sequence, the first term is

[tex]a=3[/tex]

and the fourth term is

[tex]ar^{4-1} = ar^3 = 1029[/tex]

Substitute [tex]a=3[/tex] into the second equation and solve for [tex]r[/tex].

[tex]3r^3 = 1029 \implies r^3 = 343 \implies r = \sqrt[3]{343} = \sqrt[3]{7^3} = 7[/tex]

Then the two terms between the 1st and 4th - i.e. the 2nd and 3rd terms - are

[tex]ar = 3\times7 = \boxed{21}[/tex]

and

[tex]ar^2 = 3\times7^2 = \boxed{147}[/tex]

Answer:

Term 2 is 21, and term 3 is 147.

Step-by-step explanation:

The geometric sequence is 3, 3r, 3r^2, 1029.

[tex]r = \sqrt[3]{ \frac{1029}{3} } [/tex]

[tex]r = \sqrt[3]{343} = 7[/tex]

So we have 3, 21, 147, 1029.

The most economic way to purchase health insurance for the family would be to insure Patrick with his employer and Susie and the twins with her employer (Option c).

Reason behind the Choice

Patrick's employer pays for 100% of his monthly health insurance premium of $378

In this case, additional beneficiary for the twins = $280*2 = $560

Susie's employer pays 63% of her $403 monthly premium, and is ready to pay 32% of the $310 monthly premium for each additional beneficiary.

Total money to be paid in this case = 37% of $403 +2*(68% of $310)

= $570.71

Considering that Patrick's health insurance cost is lower than Susie's, it makes sense for him to get health insurance via Patrick's company.

For the twins, Susie's employer offers to pay 68% of $310 for each additional beneficiary. So, the most viable deal would be to buy Patrick's health insurance from his employer and Susie and the twin's health insurance from her employer.
