The population density of otter, raccoon, fox and bobcat is 0.3125, 1.66, 0.0803 and 0.0267 per acre

Total park area of the state park = 112 acres

Number of Otter = 35

Number of Raccoon = 186

Number of Fox = 9

Number of Bobcat = 3

The formula of population density is given by:

Population Density = Number of animals/Area of land

Population density of Otter in the park = 35/112 = 0.3125 Otter per acre

Population density of raccoon in the park = 186/112 = 1.66 Raccoon per acre

Population density of fox in the park = 9/112 = 0.0803 Fox per acre

Population density of bobcat in the park= 3/112 = 0.0267 bobcat per acre

Definition of Hyperbola=a symmetrical open curve formed by the intersection of a circular cone with a plane at a smaller angle with its axis than the side of the cone.

Formula=[tex](x-x1)^{2}[/tex]/[tex]a^{2}[/tex] - [tex](y-y1)^{2}[/tex]/[tex]b^{2}[/tex]=1

Given,

origin o(0,0) , focus s(-3,0) , vertex v(-2,0)

  then,     equation of hyperbola becomes= [tex]x^{2}[/tex]/[tex]a^{2}[/tex]-[tex]y^{2}[/tex]/[tex]b^{2}[/tex]=1

a is the distance between center and the vertex,

    distance between o and v = 2

c is the distance between center and the focus,

   distance between o and s =3

y = -8.

An ordered pair is a composition of the x coordinate and the y coordinate, having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension.

Ordered pairs are often used to represent two variables. When we write (x, y) = (7, - 2), we mean x = 7 and y = - 2. The number which corresponds to the value of x is called the x-coordinate and the number which corresponds to the value of y is called the y-coordinate.

see attachment for the table

we observe from the given table that

As x increases by 2, y decreases by 4

As x decreases by 2, y increases by 4

for example x = 10, y = -12

when x decreases by 2 (to 8), the value of y will increase by 4 (to -8).

Hence, the value of y when x = 8 is -8

  x = 11°

Step-by-step explanation:

You want to know the value of x given a triangle with exterior angles 147°, 4x, and an interior angle of x at the third vertex.

The exterior angle of the triangle at B is the supplement of x: 180°-x. The sum of the exterior angles of a polygon is 360°, so we have ...

  147° +4x +180° -x = 360°

Collecting terms, we have ...

  327° +3x = 360°

  3x = 33° . . . . . . . . . subtract 327°

  x = 11° . . . . . . . . . . divide by x

Number of households only own one or more DVD players = 219

Total number of households considered for the survey = 400

Let n(A) represent the number of households only own one or more HDTVs.

Then n(A) = 315

Let n(B) denotes the number of households only own one or more DVD players. We need to find n(B).

Number of households own one or more HDTVs and one or more DVD players, n(A∩B) = 150

Number of households do not own an HDTV or a DVD player = 16

So the number of households which own an HDTV or a DVD player, n(A∪B) = 400 - 16 = 384

Then we have the formula relating n(A∪B), n(A), n(B) and n(A∩B).

n(A∪B) = n(A) + n(B) - n(A∩B)

⇒ n(B) = n(A∪B) - n(A) + n(A∩B)

           = 384 - 315 + 150

           = 219

The number of households only own one or more DVD players = 219

Answer:

Step-by-step explanation:

Given two points on the linear toll function T(d) are (20, 119) and (33, 184), you want the equation for the function T(d), and the value of T(96).

It is usually convenient to write the equation of a line in slope-intercept form when you want to find the value at a particular point. To use that form, we need to know the slope of the line. It is given by the formula ...

  m = (y2 -y1)/(x2 -x1)

Using the given points, we have ...

  m = (184 -119)/(33 -20) = 65/13 = 5

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

Using the first point and the slope we found, the equation is ...

  y -119 = 5(x -20)

Solving the above equation for y, we get ...

  y = 5x -100 +119 . . . . . . . simplify, add 119

  y = 5x +19 . . . . . . . . . . combine terms

Using variables d and T instead of x and y, the function is ...

  T(d) = 5d +19

The value T(96) is ...

  T(96) = 5(96) +19 = 480 +19 = 499

The toll for 96 miles is 499 cents.

Hence , the graph of the equation is y = 1.5 sin(x - 2π/3) + 3 is given below .

The general form of a sine function is of the form:

y = a×sin(bx − c) + d,

here the amplitude is a,

the period is 2π/|b|,

the phase shift is c/b, and

the vertical shift is d.

From the given equation we have,

The amplitude, a = 1.5

The period, = 2π/|1| = 2π

The phase shift = (2π/3)/1 = 2π/3

And the vertical shift is d = 2

The given equation can be graphed using the amplitude, period, phase shift, vertical shift, and points.

Graph technology aids in the discovery of unknown links in data that cannot be detected or examined using traditional methods. When the broad term graph is introduced as both a topic, it frequently blurs three distinct topics: graph theory, graph analytics, and graph data management.

Graphs and charts are useful visual tools because they deliver information quickly and readily. It is hardly surprising, then, that graphs are widely utilized in print and electronic media. Data can be easier understood when displayed as a graph rather than a table since the graph can illustrate a pattern or comparison.

y =2x² - 24x – 56​

Solving for :

Parabola equation in polynomial form

ax² + bx + c  for x = -b/(2a)

a = 2

b = -24

c = -56.

on solving we get

= -(- 24)/2* 2

= 6

The value of x = 6

putting the value of x to get y:

2x² - 24x – 56​

2(6)² - 24(6) – 56​

-128

the value of y = -128.

The slope of Parallel Lines:

Slopes of parallel lines are equal. The parallel lines are equally inclined with the positive x-axis and hence the slope of parallel lines is equal. If the slopes of two parallel lines are represented as m1, m2 then we have

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in the y-coordinate is represented by Δy and the net change in the x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = change in y/change in x = Δy/Δx

Where “m” is the slope of a line.

The slope of the line can also be represented by

tan θ = Δy/Δx

So, tan θ to be the slope of a line.

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter ‘m’

m1 = m2.

y 2/3 = x + 1 ...1

2y = 3x+3

y = 3/2x +3/2

m1= 3/2

x,y = -6,-1

y = mx +b

(y-y1 ) =m (x-x1) +b

m1=m2

m2= 3/2

(y +1) = 3/2 (x+6)

2(y+1 )= 3x+18

the equation of the line that is parallel to y 2/3 = x + 1 and passes through the point (–6, –1) = 2y+2 = 3x+18
