Step-by-step explanation:

The initial bird population density is 3713.

Given info;

A certain county received a new species of bird 25 years ago. According to biologists, the population doubles every ten years and is currently 21,000 people.

To get the initial size of the bird population;

We use the formula,

[tex]P(t)=Po* 2^\frac{t}{10}[/tex]

Where Po is the initial population and t is the time in years.

[tex]21000= P(25)=Po*2^\frac{25}{10}[/tex]

[tex]21000= Po*2^\frac{5}{2}[/tex]

[tex]21000= 4\sqrt{2}*Po[/tex]

[tex]Po = 21000/4\sqrt{2}[/tex]

[tex]Po = 3712.31\\Po = 3713[/tex]

Hence, the initial size of the bird population is 3713.

In the given question we have to graph JKL with vertices J(1, 3), K(5, 0), and L(7, 4) and its image after the glide reflection with a translation along <0,-3> and areflection in the y-axis.

The given vertices are J(1, 3), K(5, 0), and L(7, 4).

Firstly translation along (0,-3).

So translation is (x,y)→(x,y-3)

J'=(1, 3-3)=(1, 0)

K'=(5, 0-3)=(5, -3)

L'=(7, 4-3)=(7, 1)

We have to find the reflection in the y-axis so (x,y)→(-x,y).

Now the points are J'(-1, 0), K'(-5, -3), L'(-7, 1).

B) y = 30x + 15

C) (24, 735) **graph below

D) Yes, there is a proportional relationship

Step-by-step explanation:

We can represent this relationship with an equation.

y = 30x + 15

where x would represent the months and y would be the total cost. The 15 would be the initial fee, which only occurs once.

A) Using the relationship [tex]y = 30x + 15[/tex], we can substitute 2 for x, since that would represent the months.

[tex]y = 30x + 15\\y = 30(2) + 15\\y = 75[/tex]

It would be 75 dollars.

B) The total cost for x months would just be the relationship

[tex]y = 30x + 15[/tex]

C) 2 years would represent 24 months. The screen shot below would represent the relationship. The y axis would be the total cost in dollars and the x axis would be the months. (24, 735)

here, the chances of occurrence of tail and heads and equal so, this is independent event .

we want to calculate total numbers of possble wats atleast 8 heads occurs .

At least 8 heads means exactly two toss gives Tail as a result.

here we count sequences with exactly 8 heads, and also count sequences with more than three heads. We could compute this by equivalent, by subtracting from 1025 the number of sequences with no head, only one head, and only 2 heads

= 1024 - ⁸C₀ ( + ⁸C₁ + ⁸C₂ )

= 1024 - ( 1+8+28) = 1024 - 37

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Jill has 20 coins, consisting of nickels and dimes totaling $1.40.

Let the number of nickels be n, and the number of dimes is 20 - n.

The third graphical representation is that of the function y = 1/2[x] .

The given function is y = 1/2[x] .

This is called the box function or the greatest integer function.

So for the equation of the line y = 1/2 x the graph passes through origin and through the points (2,1) , (4,2) and many more.

Now for the greatest integer function will take all the values of x greater than 1 up to 2 and round it off to 2.

so the points on the graph will be.

(2,1) , (3,1.5) , (4,2)....

This is clearly seen in the third option.

The integer function that returns an integer closest to the given real number is the largest integer function. also referred to as the step function. The greatest integer function rounds the input to the nearest integer. As a result, the equation to get the greatest integer is rather simple. It has the sign x, where x can represent any value.

m∠6 = 137° because ∠5 and ∠6 are supplementary, so 43° + m∠6 = 180°

m∠7 = 137° because alternate exterior angles are congruent, so m∠7 = m∠2

m∠8 = 43° because alternate exterior angles are congruent, so m∠8 = m∠1

Step-by-step explanation:

The equation of the parabola, in vertex form, that represents the ball's distance, y, from the hole, x seconds after the ball is hit is

y = (-2m/s^2)t^2 + (-2m/s)t + 6m

ax² + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. a 0. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.

Given,

Assume for the moment that the hole is located at y = 0m, where x represents the time variable.

We are aware of:

The vertices are (-1s, 8m).

x in seconds and y in meters, I presume

The ball enters the hole at time x = 1s, hence we also have the following point:

(1s, 0m).

The vertex of the quadratic equation y = ax2 + bx + c is located at:

x = -b/2a,

Next, we have:

-1 = -b/2a.

Next, we have equations for trees:

8m = a(-1s)2, b(-1s), and c

0m = (a(1s)2) + (b(1s)2) + (c)

-1s = -b/2a.

The third equation should have one variable isolated first, and then it should be substituted in one of the other two:

1s2a = b.

Therefore, we can change b to bi 1s2a in the first two equations.

8m = 1s×2a×1s - a×1s2a1s + c

0m = 1s×2a×1s + a×1s×2a + c

We can combine the two equations to get:

8m is equal to a(1s2 - 2s2) + c, or a×1s2 - c.

0m is equal to a(1s2 + 2s2) + c, or a×3s2 + c.

We may quickly remove c from the second equation and then substitute it in the first equation:

c = -a3s^2

The initial equation is now:

8m is equal to -a×1s2 - a×3s2 - a×4s2.

a = 8m/-4s^2 = -2m/s^2.

We can now determine the values of c and b using a.

c = -(-(-2m/s2)*3s2)*3s2 = 6m.

B is equal to 1s*2a = 1s*(-2m/s2) = -2m/s.

The equation is then:

y = (-2m/s^2)t^2 + (-2m/s)t + 6m
