A number of birds of an endangered species were released in a forest preserve with a carrying capacity of 500 birds the population P of the birds can be modeled by P (t) 500/1+4.55e^-0.5t, Where t is the number of years since the birds were released
(a) When does the growth rate start to decrease?
(b) What is the initial population?
(c) What is the maximum population?
(d) What is the population of the birds after 2 years?
By analyzing the population equation we can see that:
a) For t > 0, the rate decreases.b) The initial population is 91 birds.c) The maximum population is 500.d) After 2 years the population is 187 birds.How to work with the population equation?Here we have the population equation:
[tex]p(t) = \frac{500}{1 + 4.55e^{-0.5*t}}[/tex]
a) When does the growth rate start to decrease?
The rate of change will be:
[tex]p'(t) = 0.5*\frac{500}{(1 + 4.55e^{-0.5*t})^2}*4.55e^{-0.5*t}[/tex]
Below, you can see the graph of it, and there you can see that for t > 0 the rate always decreases.
b) The initial population is what we get when we evaluate p(t) in t = 0
[tex]p(t) = \frac{500}{1 + 4.55e^{-0.5*0}} = \frac{500}{1 + 4.55} = 91[/tex]
c) What is the maximum population?
It is 500 (asymptotically), which is the value that we get when we take the limit of t to infinity.
d) The population after 2 years is given by:
[tex]p(t) = \frac{500}{1 + 4.55e^{-0.5*2}} = 187[/tex]
So after two years, there will be 187 birds.

write a division equation that represents the question: how many 3/4 are in 5/4
Answer:
1,25/0,75
Step-by-step explanation:
3/4 = 0.75
5/4= 1.25
Answer:
One. See why ↓
5/4 is an improper fraction. We want a mixed number where the numerator is greater than the denominator for this to be right, so convert 5/4 to 1 1/4.
Typically speaking, there is only 1 of 3/4 in 5/4.
If this was 6/4, 3/4 would appear twice. In this case,3/4 only appears once because it is comparing to an uneven number that is not a factor of 3. ↓Therefore,
There is 1 of 3/4 in the number, 5/4.

how do i Graph y=-1/3x+5
Answer:
Step-by-step explanation:
Given:
y = (-1/3)x +5
Compare the given equation with the general equation of the line:
y = mx+b,
where m=slope and b= y-intercept (where the line intersects the y-axis)
Our slope is m= -1/3, and our y-intercept is b=5
y-intercept is at 5 so we know one point on the line (0,5)
m= -1/3, negative slope means our line will be going down from left to right
m= rise /run = -1/3, so from point (0,5) we go down 1 (rise=-1) and right 3 (run=3) to get to a new point on the line (3, 4)
Draw a line trough the two found points (0,5) and (3,4)

Deon throws a ball into the air. The height h of the ball, in meters, at time t seconds is modeled by the function h(t)=-5t^2+t+4
will the ball reach a height of 5 meters?
Step-by-step explanation:
Proving by Vertex Form:Yes, if we put this equation in vertex form
[tex]a(x - h) {}^{2} + k[/tex]
where h,k is vertex
we can find if it reaches 5.
First we do -b/2a.
[tex] \frac{ - 1}{10} [/tex]
Is a solution, if we plug that in we get
Which gives
[tex]3.95[/tex]
So the vertex form is
[tex]5(x + 0.1) {}^{2} + 3.95[/tex]
Since the graph is facing upwards,because a is positive, the function will pass all values greater than 3.95, and 5 is one of them
Second Way: Watch if you want to see how long is reaches 5 meters.
Set the quadratic equation equal to 5.
[tex]5 {t}^{2} + t + 4 = 5[/tex]
[tex] {5t}^{2} + t - 1 = 0[/tex]
[tex]5 {t}^{2} + t - 1 = 0[/tex]
Do quadratic formula, which is
[tex] - b± \frac{ \sqrt{b {}^{2} - 4ac} }{2a} [/tex]
So a is 5 b is 1 and c is -1 so we get
[tex] - 1± \frac{ \sqrt{1 {}^{2} - 4( 5)( - 1)} }{2(5)} [/tex]
[tex] - 1± \frac{ \sqrt{1 + 20} }{10} [/tex]
[tex] - 1± \frac{ \sqrt{21} }{10} [/tex]
[tex] \frac{ - 1}{10} + \frac{ \sqrt{21} }{10} [/tex]
and
[tex] \frac{ - 1}{10} - \frac{ \sqrt{21} }{10} [/tex]
are the solutions but since time is scalar, it can't be negative so qe take the positive solution
[tex] \frac{ - 1}{10} + \frac{ \sqrt{21} }{10} [/tex]
which is approximate 0.358.
So if you wanted to know, it will take 0.36 seconds to reach a height of 5 meters.
At what point does y = 3x - 2 intercept: a) The y-axis: b) The x - axis:
Answer:
y-intercept is (0, −2)
x-intercept is (2/3, 0)
Step-by-step explanation:
y=3x-2
y=mx+c (m is the gradient and c is the y-intercept)
Therefore, the y-intercept is (0, −2)
To determine the x-intercept, we set y equal to zero and solve for x.
So, 0=3x-2. We can rearrange this... 2=3x therefore x=2/3
The x-intercept is (2/3, 0)

The rest of the puppies are shared evenly among 12 other volunteers how many puppies does each volunteer play with
help pls and thank you!
Answer:
4
Step-by-step explanation:
If Annie and her grandmother play with 5 of the puppies, subtract 5 from 53 to get 48. Since there are 12 volunteers, divide 48 by 12 to get 4. So, each volunteer plays with 4 puppies. My work is shown below.
53-5=48
48/12=4
PLEASE MARK ME AS BRAINLIEST
Answer: 4
Step-by-step explanation: Hi there
1. Subtract the number of puppies Annie plays with from the total number of puppies. 53-5=48
2. Divide the number of remaining puppies by the number of volunteers. 48/12=4
Therefore, each volunteer plays with 4 puppies.

the area formula is a parallelogram is equal to (Base)*(height). If the area if a parallelogram is given by the trinomial x^2-14x+24. The base of parallelogram is (x-2), what is an expression for the height of the parallelogram?
Answer:
x-12
Step by step explanation:
Here it is given that the area of a parallelogram is given by base * height. And if the area is represented by ,
[tex]\longrightarrow A = x^2-14x+24[/tex]
And the base of the parallelogram is given by,
[tex]\longrightarrow Base = x-2 [/tex]
Substituting the values in the given formula, we have;
[tex]\longrightarrow Area = base \times height [/tex]
[tex]\longrightarrow x^2-14x+24=h(x-2)\\ [/tex]
Divide both sides by (x-2) .
[tex]\longrightarrow h =\dfrac{x^2-14x+24}{x-2}[/tex]
Factorise the term in numerator,
[tex]\longrightarrow h =\dfrac{x^2-12x-2x+24}{x-2}\\[/tex]
[tex]\longrightarrow h =\dfrac{x(x-12)-2(x-12)}{x-2}\\ [/tex]
[tex]\longrightarrow h =\dfrac{(x-2)(x-12)}{x-2} [/tex]
Simplify,
[tex]\longrightarrow \underline{\underline{ height= x-12}} [/tex]

(Hint: Golf Ball Volume V = 4/3 π r3 ; V = 4/3 ∙ (3.14) ∙ (2.1)3 )
(Hint: Softball Volume V = 4/3 π r3 ; V = 4/3 ∙ (3.14) ∙ (4.2)3 )
Answer:
Step-by-step explanation:
Hint already gives the formulae for the balls' volume as:
Golf Ball Volume V = 4/3 π r^3 ;
V = 4/3 ∙ (3.14) ∙ (2.1)^3
Softball Volume V = 4/3 π r^3 ;
V = 4/3 ∙ (3.14) ∙ (4.2)^3
Note the volume depends on the radius to the power 3. So for a softball with double the radius of a golf ball, its volume will be 2^3 = 8 times that of the golf ball.
Golf Ball Volume = 4/3 ∙ (3.14) ∙ (2.1)^3 = 38.77 cm^3
Softball Volume = 4/3 ∙ (3.14) ∙ (4.2)^3 = 310.18 cm^3
Golf ball:-
[tex]\\ \rm\Rrightarrow V=4/3\pi (2.1)^3=4/3\pi 9.261=12.35\pi cm^3[/tex]
Soft ball:-
[tex]\\ \rm\Rrightarrow V=4/3\pi (4.2)^3 74.1=98.8\pi cm^3[/tex]
Ratio:-
[tex]\\ \rm\Rrightarrow \dfrac{12.35\pi}{98.8\pi}[/tex]
