Answer: I recommend starting treatment immediately. If you take more than 8 days to make a decision, the disease can no longer be cured because it will affect more than 50% of the body.
Step-by-step explanation:
The percentage of the body affected by the disease is a function of the number of days:
P(d) = 6d + 5This percentage is a dependent variable and the number of days is the independent variable.
If we give values to d, we can calculate the percentage of the body affected by the disease.
P(1)= 6·1 + 5 = 11%
P(2)= 6·2 + 5 = 17%
P(3)= 6·3 + 5 = 23%
P(4)= 6·4 + 5 = 29%
P(5)= 6·5 + 5 = 35%
P(6)= 6·6 + 5 = 41%
P(7)= 6·7 + 5 = 47%
P(8)= 6·8 + 5 = 53%
Depending on the days since the beginning of the disease, the doctors have a treatment for a different stage.
Starting immediately, the treatment will be stage 1: less than 15%
Starting on day 2 or 3, the treatment will be stage 2: 15-25%
After day 3, the treatment will be stage 3: 25-50%
After day 8, there is no cure: more than 50% of the body is affected by the disease.
I recommend starting treatment immediately. If you take more than 8 days to make a decision, the disease can no longer be cured because it will affect more than 50% of the body.

3. Determine whether the following table of values represents a linear, quadratic, or neither function. Show your calculations.
b) Explain how you know whether it is a linear, quadratic, or neither function.
Answer:
Quadratic function
Explanation:
It is not linear because the difference between y values is not constant.
([tex]10-5\neq 5-2[/tex] for example) In a linear function, the difference between y values would be constant.

2(t-3)² - 72 = 0. extracting square roots. with solution please
Answer:
t = 9
Step-by-step explanation:
Here, we want to find the value of t
2(t-3)^2 -72 = 0
2(t-3)^2 = 72
divide both sides by 2
(t-3)^2 = 72/2
(t-3)^2 = 36
(t-3)^2 = 6^2
Since powers are equal, we equate base
t-3 = 6
t = 6 + 3
t = 9

Write a linear equation with a slope of 14 and y-intercept -12.
Answer:
y=14x-12
Step-by-step explanation:
in the standard format y=mx+b, m is the slope and b is the y-intercept, so this equation would be y=14x-12 since the slope is 14 and the y-intercept is -12.

12x + k = c solve for x Explain how to do it please
Answer: x=(c-k)/12
Step-by-step explanation:
So you're trying to find x, and in order to do that, you need x by itself. First, move k to the right side by subtracting k from both sides to get 12x=c-k. After that, you divide 12 for both sides to get x=(c-k)/12. It looks like this: [tex]\frac{c-k}{12}[/tex]

Raina corre 7 millas en 50 minutos. A esta misma tasa, ¿qué distancia en millas correría en 75 minutos?
Responder:
10.5 millas
Explicación paso a paso:
50 / 7 = 0.14
0.14 * 75 = 10.5
Espero que esto ayude :)
Given parameters:
Distance covered by Raina = 7 miles
Time taken = 50 minutes
Unknown:
Distance covered in 75 minutes = ?
To solve this problem, we have to find the speed of Raina during the first 50 minutes.
Speed is the distance covered with time.
Speed = [tex]\frac{distance}{time taken}[/tex]
Input the parameters and solve;
Speed = [tex]\frac{7 miles }{50 minutes}[/tex] = 0.14miles/min
Now, to find the distance covered in the second run;
Distance = speed x time taken
= 0.14miles/min x 75min
= 10.5miles
The distance covered in miles is 10.5miles

9. During training, a hurdler wants to raise the height of the hurdles from the high school standard of 39 inches to the
NCAA standard of 42 inches. His best race from last season included a clear over a 39-inch hurdle that was modeled by
h(t) = (-0.0251)(1-25), where t is time (in tenths of a second) after his lead leg left the track and h is the height (in feet).
If he runs as well as his best race last year, will this hurdler clear the new height? Why or why not
Answer:
Something doesn't make sense. The time when his height is 0 is time t=0 and t=25.
The vertex would be halfway in between at time t=(0+25)/2 = 12.5 seconds.
But plugging that in, we get a height of:
3.90625 inches
I think you must have a typo... let's try this equation instead:
h(t) = (-0.25t)(t - 25)
In that case, the maximum at h(12.5) is 39.0625 inches.
Answer:
No, the function for his height has him just barely clearing 39 inches. He can't clear 42 inches.
10
No, according to the function for his height, he only just clears 39 inches. He is unable to jump 42 inches.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

find the line of the equation that passes through (3, -4) and is parallel to 3x + y + 2 = 0
leave your answer in the form of y = mx + c
hi
3x+y +2 = 0 so y = -3x-2
parrallel line has the same slope , so is -3x
then : -3 (3) +c = -4
-9 +c = -4
c = -4 +9
c = 5
so parallel is : y= -3x +5

Answer:
Domain: -5 ≤ x < 1
Range: -4 ≤ x < 7
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
Range is the set of y-values that are outputted by function f(x).
We see from the graph that our x-values span from -5 to 1. Since -5 is closed dot, it is included in the domain, but since 1 is open dot, it is not included in the domain:
[-5, 1) or -5 ≤ x < 1
We see from the graph that our y-values span from -4 to 7. Since -4 is closed dot, it is included in the range, but since 7 is open dot, it is not included in the range:
[-4, 7) or -4 ≤ x < 7
