The number of legislators has increased approximately linearly from 1138 positions in 2003 to 1222 positions in 2009 . Let n be the number of legislators at t years since 2000. Find an equation of a linear model to describe the data.

Answers

Answer 1

The equation of a linear model to describe the data is 14x - y = 26904

To find a linear equation of the provided data,

Let us put the number of legislature on the y axis and the year corresponding at the x axis,

According to provided information,

In year 2003, the number of legislature is 1138.

In year 2009, the number of legislature is 1222.

So here we have two points,

A(2003,1138) and B(2009,1222).

As we have two points now,

We can use the two point form of the line to find the equation of line,

It says if we have two point (a,b) and (c,d), then the equation of line is,

(y-b)/(x-a) = (d-b)/(c-a)

So, our equation of line is with points A and B is,

(y - 1138)/(x-2003) = (1222-1138)/(2009-2003)

(y-1138)/(x-2003) = 14

y - 1138 = 14x - 28042

14x - y = 26904

When,

x = 2000, y = n,

14(2000) - n = 26904

n = 1096.

The Linear Equation is 14x - y = 26904

Let in 5% account invested amount is x

then amount in 6% account is (9000-x)

Then,

[tex]5\%\text{ of }x+6\%\text{ of }(9000-x)=510[/tex]

Then the value of "x" is:

Which relation is a function?

Answers

let's recall the vertical line test, if a vertical line hits the graph or points twice, then is NOT a function.  Check the picture below.

A very easy way to find out if a graph is a function is to use the vertical line test.

Look at each graph and mentally draw a vertical line that goes through each of its points.

If that line goes through more than one point (2, 3, 4...) then that graph is not a function.

That's because a function, is an equation for which each input (x value) has exactly one output (y value). There cannot be two points of the same x value, with two different y values.

What is coordinate system?

A Cartesian coordinate system in some kind of a plane is a system of coordinates that uniquely identifies each point by a pair of numerical coordinates, which are the signed distances from two fixed perpendicular lines that are aligned to the point and are both measured in the same length.

According to the given data:

point of the coordinates are as follows:

A(2, 1)

B(8, 6).

C(10, 1)

We know that the formula for finding for the distance is:

d=√((x2 – x1)² + (y2 – y1)²).

For Point AB:

X₁ = 2

Y₁ = 1

X₂ = 8

Y₂ = 6

putting the values onto formula we get:

d=√((x2 – x1)² + (y2 – y1)²).

d=√((8 – 2)² + (6 – 1)²).

d=√((6)² + (5)²).

d=√(36 + 25).

d=√(61).

AB =7.81

For Point BC:

X₁ = 8

Y₁ = 6

X₂ = 10

Y₂ = 1

putting the values onto formula we get:

d=√((x2 – x1)² + (y2 – y1)²).

d=√((10 – 8)² + (1 – 6)²).

d=√((2)² + (-5)²).

d=√(4 + 25).

d=√(29).

BC = 5.38

For Point CA:

X₁ = 10

Y₁ = 1

X₂ = 2

Y₂ = 1

putting the values onto formula we get:

d=√((x2 – x1)² + (y2 – y1)²).

d=√((2 – 10)² + (1 – 1)²).

d=√((-8)² + (0)²).

d=√(64 + 0).

CA = 8

The perimeter of the given figure is:

Sum of all the sides.

AB + BC + CA

7.81 + 5.38 + 8

21.19 cm

Now finding the area of the tringle we use Pythagoras formula:

H² = P² + B²

P² = H²  - B²

P² = (7.81)²  - (5.38)²

P = 9.4837

We know that the area of the triangle is: = 1/2(base * Hight).

                                                                    = 1/2(5.38  * 9.48)

When two lines are intersected by a transversal and the opposing interior angles line up, the intersected lines are said to be parallel. Two lines are said to be parallel if they are divided by a transversal such that their opposing exterior angles are equivalent.

Therefore,

Given line m is parallel to line m

Interior Angle Theorem asserts that the alternate interior angles that result when two parallel lines are cut by a transversal are equivalent.

Alternate Exterior Angles are congruent if a transversal cuts two parallel lines. When a transversal cuts two parallel lines, the resulting angles are congruent.

Therefore, ∠2 = ∠6

∠2 + ∠4 = 180° ( Sum of the angles on a straight line is 180°)

∠6 + ∠8 = 180° ( Sum of the angles on a straight line is 180°)

Considering a parabolic equation with a vertex of (-7,-2) and directrix of x = -1. This is a horizontal parabola

What is directrix of a parabola?

The directrix of a parabola is a straight line perpendicular to the axis of symmetry of the parabola.

The directrix does not touch the parabola

How to determine if a parabola is vertical or horizontal using the directrix

A parabolic equation is also called quadratic equation.

Since the directrix is perpendicular to the axis of symmetry of the parabola it means that if:

when the directrix is given at x, the directrix runs in the vertical direction and the parabola is a horizontal parabolawhen the directrix is given at y, the directrix runs in the horizontal direction and the parabola is a vertical parabola

The axis of symmetry says if the parabola is vertical or horizontal, when the axis of symmetry is parallel:

Answers

The pancakes stall sells total 12 combinations of pancakes.

What is Combination?

Combinations are mathematical operations that count the number of potential permutations for a set of elements when the order of the selection is irrelevant.

According to the given data:

Savory pancakes can have 3 toppings in any combination.

Therefore, total number of savory pancake combinations = 3 x 2 x 1 = 6

For sweet pancakes jams can either have ice cream or fresh cream.

Therefore combinations with ice cream = 3

And combinations with fresh cream = 3

Hence total combinations for sweet pancakes = 3 + 3 = 6

Now, total pancakes combination = 6 + 6 = 12

So, the stall sells 12 combinations of pancakes.

The coordinates of the point P lying between AB is found as (7, -2/5).

What is termed as the section formula?The Section formula is used to calculate the coordinates of a point that separates a line segment either internally or externally into a certain ratio. When a point separates a line segment in some ratio, we just use section formula to determine the coordinates of the that point.

For the given question;

The two end coordinates are;

(x₁, y₁) = (8, 0)

(x₂, y₂) = (3, -2)

The ratio of the division is;

AP/PB = 1/4

OR

m:n = 1:4

The Formula for finding the coordinates of P for internally crossing is;

x = (mx₂ + nx₁)/(m + n)

y = (my₂ + ny₁)/(m + n)

Put the values;

x = (mx₂ + nx₁)/(m + n)

x = (1×3 + 4×8)/(1 + 4)

x = (3 + 32)/5

x = 7

Now for y coordinates.

y = (my₂ + ny₁)/(m + n)

y = (1×(-2) + 4×0)/(1 + 4)

y = -2/5

Thus, the coordinates of the point P lying between AB is found as (7, -2/5).

To do so, we will make use of

[tex]y=x^2-(sum\text{ of roots})x+product\text{ of roots}[/tex]

So we will follow the steps below

[tex]\begin{gathered} Sum\text{ of roots = 3+}-7=-4 \\ product\text{ of roots =3\lparen-7\rparen=-21} \end{gathered}[/tex]

substituting the above, we will have

[tex]\begin{gathered} x^2-(-4)x+(-21)=0 \\ \\ x^2+4x-21=0 \end{gathered}[/tex]

Therefore, the quadratic equation is

[tex]x^2+4x-21[/tex]

√3(√6+√15) please simplify, thanks

Explanation:

I distributed and used the idea that sqrt(A*B) = sqrt(A)*sqrt(B) to combine square roots, but also to break them up when factor out the largest perfect square factor.

Optionally for the last step, you could factor out 3, but your teacher may want you to leave it like shown.

A used car dealership is interested in the age of a used car and the price of the vehicle. The manager collects a simple random sample of vehicles as shown in the table.
The equation of the least-squares regression line is
ŷ = 19.2 – 0.868x, where ŷ is the price of the vehicle (in thousands of dollars) and x is the age (in years). Which shows the residual plot?
