The number of bald eagles in the state in the winter of 2000 is
(Round to the nearest whole number.)
Save
The number of bald eagles in a state during the winters from 1996 to 2002 can be modeled by the quartic function
f(x) = -3.334x4 +35.607x3-97.645x² +41.268x + 177.537
where x is the number of years since 1996. Find the number of bald eagles in the state in the winter of 2000.

The slope of the linear equation is 0, so this is a horizontal line.

A linear equation is of the form:

y = a*x + b

Where a is the slope and b is the y-intercept.

Particularly, if a a line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

Here we have the points  (7, -4) and (11,−4), then the slope is:

a = (-4 + 4)/(11 - 7) = 0

The recursive formula of the arithmetic sequence is:

xₙ = n*4 + 13

With that we can see that x₁₁ = 57

Here we know that the first elements of the sequence are:

17, 21, 25, 29, ...

To find the common difference, d, we take the difference between any two consecutive elements, so we have:

c = 21 - 17 = 4

Then the recursive formula for the n-th term is:

xₙ = n*4 + d

The first element x₁ is 17, so we will have:

17 = 1*4 + d

17 - 4 = d = 13

The recursive formula is:

xₙ = n*4 + 13

b) the eleventh term of the sequence is given by replacing n in the above formula by 11.

The counterexample of the statement "the difference of two numbers is greater than the greater number if the smaller number is greater than twice the additive inverse of the greater number"

"The difference of two numbers less than the greater number," is how the claim is expressed.

Give us x and y, where x is greater than y.

Thus, the statement can be interpreted as follows:

x - y < x

To both sides, add x.

-y < 2x

Replace with: y > -2x

This indicates that only when the smaller number is higher than twice the additive inverse of the larger number is the assertion true.

The smaller number must be bigger than twice the additive inverse of the larger number in order for the statement "the difference of two numbers is greater than the greater number" to be false.

The area hexagon using Lin's and Andre's method is:

By Lin's method = 93.48inch^2

By Andre's method = 93.53 inch^2

What is Mensuration ?

The field of mathematics known as mensuration explores how to measure geometric objects and their attributes, such as length, volume, shape, surface area, lateral surface area, etc.

By Lin's method

He parted the hexagon into six equilateral triangle

So, area of equilateral triangle = √3/4 × (side)^2

Since the given side = 6inch

Therefore,

                area of equilateral triangle = √3/4 × (6)^2

                                                              =√3/4 × 36

                                                              = √3 x 9

                                                              = 1.732 x 9

                                                              = 15.58inch^2

The area of hexagon will be = 15.58 x 6

                                               = 93.48inch^2

Now, By Andre's method

he parted two triangle and one rectangle

The triangle has two equal side that means its an isosceles triangle

Area of isosceles triangle using only sides = ½[√(a^2 - b^2/4) × b]

given,

base = 10.4 inch

side = 6 inch

Area of isosceles triangle using only sides = ½[√(a^2 - b^2/4) × b]  

                                                                       = ½[√(6^2 - 10.4^2/4) × 10.4]

                                                                       = ½[√(36 - 108.16 /4) ×10.4]

                                                                       = ½[√(36 - 27.04) × 10.4]      

                                                                       = ½[√(8.96) × 10.4]

                                                                       = ½[2.99 × 10.4]  

                                                                       = 15.56inch^2

for two triangles the area will be =    15.56 x 2

                                                      = 31.13 inch^2

Now, area of rectangle = length x width

where,

Length = 10.4 inch

Width = 6 inch

So,

     area of rectangle = 10.4 x 6

                                   = 62.4 inch^2

Then, The area of hexagon will be = area of rectangle + area of two triangle

                                                          = 62.4 inch^2 + 31.13 inch^2

                                                          = 93.53 inch^2

Hence, by both methods the area from Lin's method = 93.49 inch^2

and by Andre's method = 93.53 inch^2

Answer:

y = x in the slope intercept form

y - 2 = 1(x -2) in the point-slope form of a line

Step-by-step explanation:

Perpendicular slopes are opposite reciprocals of each other.  So the perpendicular slope would be 1.

We could write this in the point slope form of a line and the answer would be:

y - 2 = 1(x -2)  This would be the point slope form of a line.

If you want your answer in the slope intercept form

y -2 = 1(x-2)

y - 2 = x - 2  Add two to both sides

Jasim's last week's total pay was £286.2.

Tabular data is data presented in the form of rows and columns.

Here,

Total time for which Jasim works last week = 30 hours

Time for which Jasim works at the weekend = 12 hours

Time for which Jasim works at the weekdays = (30 - 12) hours

                                                                           = 18 hours

Jasim's pay during weekdays = £8.70

Jasim's pay during weekends = £10.80 per hour

Jasim's pay during weekdays last week = £8.70 [tex]\times[/tex] 18

                                                                   = £156.6

Jasim's pay during weekends = £10.80 per hour

The $7,834.54 borrowed at 18.6% annual interest rate with the landscape architect's monthly payment of $500, gives the number of months it will take to repay the debt as approximately 19 months

Monthly payment on a loan, is the amount the person who takes the loan, pays each month in order to settle the loan in a given time period.

The monthly payment formula is presented as follows;

[tex] \displaystyle{M = \frac{P \cdot \left( \frac{r}{12} \right) \cdot \left( 1 + \frac{r}{12} \right)^{n} }{\left( 1 + \frac{r}{12} \right)^{n} - 1} }[/tex]

Where;

M = The amount the landscape architect paid monthly = $500

P = The amount loaned or borrowed = $7,834.54

r = The interest per annum = 18.6%

n = The number of monthly payment made

Therefore;

[tex] \displaystyle{500 = \frac{7834.54 \cdot \left( \frac{0.186}{12} \right) \cdot \left( 1 + \frac{0.186}{12} \right)^{n} }{\left( 1 + \frac{0.186}{12} \right)^{n} - 1} }[/tex]

Evaluating the above equation gives;

[tex] \displaystyle{500 = \frac{121.43537.1 \cdot 1.0155^{n} }{1.0155^{n} - 1} }[/tex]

[tex] \displaystyle{500 \times (1.0155^{n} - 1) = 121.43537.1 \cdot 1.0155^{n} }[/tex]

[tex] \displaystyle{500 \times 1.0155^{n} - 121.43537.1 \cdot 1.0155^{n} ) = 500 }[/tex]

Which by taking natural logarithms of both sides gives;

n•ln(1.0155) = ln(1.32077843609)

n = ln(1.32077843609) ÷ ln(1.0155) ≈ 18.09

The estimation of 783 + 329 = 1100.

Although the term "rounding" is a general one, we typically use the terms "round up" or "round down" to indicate whether the number has gone up or down after being rounded. The supplied number is said to be rounded up when the rounded number is increased, and it is said to be rounded down when the rounded number is dropped.

Given:

783 + 329

Now rounding off nearest hundred

The graph represents the given parameter

From the graph, the points are given as

(0, 1) and (2, -2)

Calculate the slope of the points using

Slope = (y₂ - y₁)/(x₂ - x₁)

Rewrite as

m = (y₂ - y₁)/(x₂ - x₁)

This means that

Slope = m

So, we have the following representation

m = (-2 - 1)/(2 - 0)

Evaluate

m = -3/2

The equation of the line is then calculated as

y = m(x - x₁) + y₁

Where

(x₁, y₁) = (2, -2)

m = -3/2

So, we have

y = -3/2(x - 2) - 2

Add 2 to both sides

y + 2 = -3/2(x - 2)
