2.1. Provide a general rule to describe the relationship between the dates of spread and number of people infected infected.
The relationship between the dates of spread and the number of people infected can vary depending on various factors such as the infectiousness of the disease, the effectiveness of containment measures, population density, and individual behaviors.
However, there is a general rule that can describe the relationship:As the dates of spread progress, the number of infected individuals tends to increase initially, reaching a peak, and then gradually decreasing over time.
This pattern is often referred to as the epidemic curve or the epidemiological curve. In the early stages of an outbreak, the number of cases may grow rapidly as the disease spreads through a susceptible population. This rapid increase is often influenced by factors such as the contagiousness of the disease, population density, and social interactions.
As containment measures, such as vaccination campaigns, public health interventions, and behavioral changes, are implemented, the rate of new infections may start to decline. This can lead to a peak in the number of cases, after which the curve gradually decreases as the disease is brought under control and fewer susceptible individuals remain.
It's important to note that the specific shape, duration, and magnitude of the epidemic curve can vary significantly depending on the disease and the effectiveness of the response measures implemented. Additionally, emerging variants, changes in behavior, and other factors can impact the trajectory of the epidemic curve.

What is the slope of the equation y-3 = -4(x - 5)?
By answering the presented question, we may conclude that As a result, the slope of \(y_3\) = -4(x - 5) is -4.
what is slope?The slope of a line indicates how steep it is. The term "gradient overflow" refers to a mathematical equation for the gradient (the change in y divided by the change in x).
The slope is defined as the ratio of the vertical change (rise) between two places to the horizontal change (run). The slope-intercept form of an equation is used to express a straight line's equation, which is written as y = mx + b.
The y-intercept is found where the slope of the line is m, b is b, and (0, b). For example, the slope and y-intercept of the equation y = 3x - 7 (0, 7). The slope of the line is m. b is b at the y-intercept, and (0, b).
The above equation is in point-slope form: y - \(y_1\)= m(x - \(x_1\)), where (\(x_1\), \(y_1\)) is a point on the line and m is the slope.
We can see by comparing the provided equation to the point-slope form that \(x_{1} ,y_1\)) = (5, 3) and m = -4.
As a result, the slope of \(y_3\) = -4(x - 5) is -4.

What is transformation?Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. In geometry, object transformations constitute the foundation for the majority of proofs. The transformation, or f: X X, is the name given to a function, f, that maps to itself. After the transformation, the pre-image X becomes the picture X. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, can be used in this transformation.
The coordinate of X is (x , y ) is (-1, 7), hence the value of X' when the coordinates are transformed would be:
(x,y) → (y, -x)
(-1, 7) → (7, -1)
Hence, Tara is correct in the first question.

A real estate agent has 8 master keys to open several new homes. Only 1 master key will open any given house. If 40% of these homes are usually left unlocked, what is the probability that the real estate agent can get into a specific home if the agent selects 3 master keys at random before leaving the office?
Answer:
Step-by-step explanation:
Suppose F represents the value that a room is unlocked.
Then, we can assume that the probability of unlocked homes is:
P(unlocked homes) = P(U)
P(unlocked homes) = 40%
P(unlocked homes) = 0.40
Also, let us represent the value of the locked room with G.
P(locked homes) = P(G)
P(locked homes) = (1 - 0.40)
P(locked homes) = 0.60
Let the probability of selecting a correct key be P(S)
It implies that for the agent to use 3 keys, we have a combination of \(^8C_3\) possible ways for the set of keys.
Now; since only one will open the house, then:
P(select correct key) = P(S)
\(P(S) = \dfrac{ (^1_1) (^7_2) }{ ^8_3 }\)
\(P(S) = \dfrac{21}{56}\)
P(S) = 0.375
Finally, for the real estate agent to have access to specific homes supposing the agent select three master keys at random prior to the time he left his office, Then:
P(F ∪ (G∩S) = P(F) + P(G∩S)
P(F ∪ (G∩S) = P(F) + P(G) × P(S)
P(F ∪ (G∩S) = 0.40 + (0.60×0.375)
P(F ∪ (G∩S) = 0.40 + 0.225
P(F ∪ (G∩S) =0.625

−4≤t≤5minus, 4, is less than or equal to, t, is less than or equal to, 5?
The average rate of change over is 1.
Given that;
the function is,
⇒ g (t) = - (t - 1)² + 5
Hence, We need to determine the average rate of change over the interval - 4 ≤ t ≤ 5.
The value of G(-4):
The value of G(-4) can be determined by substituting t = -4 in the function
⇒ g (t) = - (t - 1)² + 5
Thus, we have,
⇒ g (t) = - (-4 - 1)² + 5
⇒ g (t) = - 20
Thus, the value of G(-4) = -20
The value of G(5):
The value of G(5) can be determined by substituting t = 5 in the function , we get,
⇒ g (t) = - (t - 1)² + 5
⇒ g (t) = - (5 - 1)² + 5
⇒ g (t) = - 11
Thus, the value of G(5) is, -11
Now, Average rate of change:
The average rate of change can be determined using the formula,
⇒ G(b) - G (a) / (b - a)
where, a = - 4 and b = 5
Substituting the values, we get,
⇒ G(5) - G (-4) / (5 - (-4))
⇒ ( - 11 - (- 20)) / 9
⇒ 9/9
⇒ 1
Thus, the average rate of change over the interval is. 1.

12p+12=120 1. subtract 12 on both sides
12p=108 2. divide 12 on both sides

Here is the most simple way to solve:
Instead of distributing the 6 into the parenthesis, you can simply divide both sides by 6:
\(6(2p+2)=120\\\frac{6(2p+2)}{6} =\frac{120}{6}\)
\(2p+2=120\)
Subtract each side by 2 to isolate the variable:
\(2p+2=20\\2p+2-2=20-2\)
\(2p=18\)
Divide both sides by 2 to have the coefficient of the variable be 1 (Because thats how we solve these kinds of equations!)

The correct option for the given sum is option B. The point (2,-9) paired with (2, 3), will make a side equal to this length.
Let the other point of the pentagon will be M(n, o).
The given point be A (a, b)
Also given one of the sides of a pentagon has length 12.
Now, we need to find the distance between the two points,
Distance between two points: |AM| = √\((a-n)^2+(b-o)^2\)
Now,
\(12 = \sqrt{(2-n)^2+(3-o)^2}\)

The table shows how many Calories Lance burns jogging on a treadmill for different lengths of time. Lance's goal today is to burn 380 Calories. If he has been jogging for 25.5 minutes, for how many more minutes does he still need to jog? Assume the situation is proportional.
Lance needs to jog for an additional 316.08-25.5 = 290.58 minutes to burn 380 Calories.
The information given in the table to produce a direct equation that relates the number of Calories burned to the time spent jogging. Let's use the pitch- intercept form y = mx b, where y represents the number of Calories burned( in hundreds), x represents the time spent jogging( in twinkles), m represents the rate of Calories burned( in hundreds per nanosecond), and b represents the original Calories burned( in hundreds). To find m, we can use the points( 10, 13) and( 15, 19), which represent two ordered dyads on the line. We can find the pitch of the line using the pitch formula
m = ( y2- y1)/( x2- x1) m = ( 19- 13)/( 15- 10)
m = 1.2 So the equation for the line is y = 1.2 x b.
To find b, we can use the point
( 10, 13) = 1.2( 10) b b = 0.7
So the complete equation for the line is y = 1.2 x0.7 Now we can use this equation to break for x, the number of twinkles Lance needs to jog to burn 380 Calories.
380 = 1.2 x0.7 = 1.2 x x = 316.08
So Lance needs to jog for an additional 316.08-25.5 = 290.58 minutes to burn 380 Calories.

The volume of a spherical sculpture is 256 ft³. Rhianna wants to estimate the surface area of the sculpture. To do the estimate, she approximates π using 3 in both the surface area and volume formulas for a sphere.
Using this method, what value does she get for the approximate surface area of the sculpture?
Answer:
192 \(ft^2\)
Step-by-step explanation:
Given that
Volume of spherical sculpture = 256 ft³
\(\pi\) is used as 3.
To find:
Surface area of sculpture = ?
Solution:
First of all, let us learn about the formula for Volume and Surface Area of Sphere:
1. \(Volume =\frac{4}{3}\pi r^3\)
2. \(Surface\ Area = 4\pi r^2\)
Given volume is 256 ft³.
\(256 = \dfrac{4}{3}\pi r^3\\\Rightarrow 256 = \dfrac{4}{3}\times 3 r^3\\\Rightarrow 256 = 4 r^3\\\Rightarrow r^3=64\\\Rightarrow \bold{r = 4\ ft}\)
Now, let us put r = 4 in the formula of Surface Area to find the value of Surface Area:
\(Surface\ Area = 4\pi 4^2 = 4 \times 3 \times 16 = \bold{192\ ft^2}\)
So, approximate surface area of sculpture is 192 \(ft^2\).
