Using the logistic equation, it is found that the number of people infected after t days is given by:
[tex]P(t) = \frac{2603}{1 + 26.4e^{-0.59t}}[/tex]
What is the logistic equation?It is given by:
[tex]P(t) = \frac{K}{1 + Ae^{-kt}}[/tex]
[tex]A = \frac{K - P(0)}{P(0)}[/tex]
In which:
K is the carrying capacity.P(0) is the initial amount.k is the rate.In this problem, the parameters are as follows: K = 2603, P(0) = 95, k = 0.59.
Hence:
[tex]A = \frac{K - P(0)}{P(0)} = \frac{2603 - 95}{95} = 26.4[/tex]
Then:
[tex]P(t) = \frac{K}{1 + Ae^{-kt}}[/tex]
[tex]P(t) = \frac{2603}{1 + 26.4e^{-0.59t}}[/tex]

Make a number line and mark all the points that represent the following values of x.
X<-2 and x <-5
The inequality expressions x < -2 and x < -5 are used to illustrate unequal values
How to determine the number linesNumber lines are used to represent numbers at regular intervals
The expressions are given as:
x < -2 and x < -5
The above expression means that:
x is less than -2 and x is less than -5
Both statements cannot always be true.
However, x is less than -5 is true for the expressions x < -2 and x < -5
So, we represent the inequality x < -5 on the number line

Is the point (11,5) on the parabola? Show or explain your work.
Answer:
The point (11, 5) is NOT on the parabola.
Step-by-step explanation:
Let [tex](x_0,y_0)[/tex] be any point on the parabola
Let [tex](a, b)[/tex] be the focus
Let [tex]y=c[/tex] be the the directrix
Distance between [tex](x_0,y_0)[/tex] and the focus: [tex]\sqrt{(x_0-a)^2+(y_0-b)^2}[/tex]
Distance between [tex](x_0,y_0)[/tex] and the directrix is [tex]|y_0-c|[/tex]
Given:
focus (6, 4)directrix y = 0Therefore:
Distance between [tex](x_0,y_0)[/tex] and the focus: [tex]\sqrt{(x_0-6)^2+(y_0-4)^2}[/tex]
Distance between [tex](x_0,y_0)[/tex] and the directrix is [tex]|y_0-0|[/tex]
Equate the two expressions and solve for [tex]y_0[/tex]:
[tex]\sqrt{(x_0-6)^2+(y_0-4)^2}=|y_0-0|[/tex]
[tex]\implies (x_0-6)^2+(y_0-4)^}=(y_0-0)^2[/tex]
[tex]\implies {x_0}^2-12x_0+36+{y_0}^2-8y_0+16={y_0}^2[/tex]
[tex]\implies {x_0}^2-12x_0-8y_0+52=0[/tex]
[tex]\implies 8y_0={x_0}^2-12x_0+52[/tex]
[tex]\implies y_0=\dfrac18{x_0}^2-\dfrac{12}{8}x_0+\dfrac{52}{8}[/tex]
[tex]\implies y_0=\dfrac18{x_0}^2-\dfrac32x_0+\dfrac{13}{2}[/tex]
Now rewrite with (x, y):
[tex]\implies y=\dfrac18x^2-\dfrac32x+\dfrac{13}{2}[/tex]
Therefore, this is the equation of the parabola
To determine if the point (11, 5) is on the parabola, input x = 11 into the equation:
[tex]\implies y=\dfrac18(11)^2-\dfrac32(11)+\dfrac{13}{2}[/tex]
[tex]\implies y=\dfrac{41}{8}[/tex]
So the point (11, 5) is NOT on the parabola.

The scores for today's math quiz are 75, 95, 60, 75, 95, and 80. Explain the steps needed to create a histogram for the data. PLEASE MAKE THE ANSWER SCHOOL APPROPRIATE.
Answer:
Chill, it ain't complicated
Step-by-step explanation:
A histogram is basically a bar graph but there's no space between the bars.
The graph has to be the dependent component (the score) against the independent component (the number of students who took the math quiz)
Depending on your size of paper pick a simple scale (1 cm could be either 5% or 10%)
Leave some space between the y (vertical) axis and the first bar.
Do them in the order they appear, i.e 75, 95... 80
