7. Suppose a parabola has vertex (-4,7) and also passes through the point (-3,8). What is the equation
of the parabola in vertex form?
y=(x+4)^2 +7
y= 2(x+4)^2 +7
y= 2(x+3)^2 +8
y=(x-4)^2 +7
9514 1404 393
Answer:
(a) y=(x+4)^2 +7
Step-by-step explanation:
The vertex form equation is ...
y = a(x -h)^2 +k
for vertex (h, k) and vertical scale factor 'a'.
The vertex is given as (h, k) = (-4, 7), so the equation will be ...
y = a(x +4)^2 +7
The value of 'a' can be found from the other given point:
8 = a(-3+4)^2 +7
1 = a
So, the equation is ...
y = (x +4)^2 +7
One method of slowing the growth of an insect population without using pesticides is to introduce into the population a number of sterile males that mate with fertile females but produce no offspring. If P represents the number of female insects in a population, S the number of sterile males introduced each generation, and r the population's natural growth rate, then the female population is related to time t by
t =
P+S
P[(r−1)P − S]
dP
Suppose an insect population with 10,000 females grows at a rate of r = 0.10 and 900 sterile males are added in each generation. Evaluate the integral to give an equation relating the female population to time. (Note that the resulting equation cannot be solved explicitly for P.)
The equation relating female population with time requested by t = -ln(P) - 1/9ln(P + 1000)- 1/9ln(9/10)
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that the female population is related to time t by;
[tex]t = \int\limits {\frac{(P+S)}{P((r-1)P-S)} } \, dP[/tex]
Now, to do partial fraction;
(P+S)/P((r-1)P-S) = A/P + B/((r-1)P-S)
P + S = A((r-1)P -S) + PB
if P = 0, then:
A = -1
If (r-1)P - S = 0
p = S/(r-1)
B = 1 + r - 1
B = r
Therefore,
[tex]t = \int\limits {\frac{(P+S)}{P((r-1)P-S)} } \, dP[/tex]
t = -ln|P| + ln|(r-1)P-S| + 1/r-1 x integral((r-1)/[(r-1)P-S])
t = -ln|P| + ln|(r-1)P-S| + ln|(r-1)P-S|/(r-1)
t = -ln|P| + (r/r-1)ln|(r-1)P-S|
Now substituting known constants then;
t = -ln|P|-1/9(ln|-0.9P - 900|)
t = -ln|P| - 1/9(ln|-0.9P -900|)
t = -ln|P| - 1/9(ln(|(-9/10)(P + 1000)|))
t = -ln(P) - 1/9ln(P + 1000)- 1/9ln(9/10)
as P >= 0, ln(P) and ln(P + 1000) doesn’t need abs value
Therefore, the equation relating female population with time requested by t = -ln(P) - 1/9ln(P + 1000)- 1/9ln(9/10)

Part A
As the company has increased in popularity, it has continued to add employees in all departments. The production facility manager has provided data that shows the relationship between the number of units produced in an hour and the number of workers on the production line during that hour. The data is shown in the table.
Question 1: What type of function would be model the data?
Question 3: Use the graphing tool and best fit function of the tool to write a function that models the data. Round coefficients and constants to the nearest hundredth.
Question 4: Produce about 2300 fidget spinners every hour. How many workers should Marco recommend. Show your work.
9514 1404 393
Answer:
1. a linear model
3. y = 24.97x +417.59
4. 75 workers
Step-by-step explanation:
1. A graph of the data seems to show it nearly follows a straight line. We have used a linear function to model the data.
3. The linear regression model is ...
y = 24.97x +417.59
4. The graphing calculator shows the point (x, y) ≈ (75.4, 2300) is on the line of best fit. Marco should recommend 75 workers for production of 2300 units per hour.
If you want to solve the linear equation ...
2300 = 24.97x +417.59
you get ...
x = (2300 -417.59)/24.97 ≈ 75.4
About 75 workers are needed.
