A virus jumps from monkeys to humans. The number of people P(t) who have been infected with the virus t weeks after the jump grows logistically. Suppose that initially 10 people are infected with the virus and that the continuous growth rate is 1.78. It is estimated that in the long run approximately 5000 people will have been infected with the virus. The virus is spreading the fastest approximately:________
a. 3.5 weeks after the jump.
b. 4.0 weeks after the jump.
c. 4.5 weeks after the jump.
d. 5.0 weeks after the jump.
e. None of the above is correct.
Answers
Answer:
e. None of the above is correct.
Step-by-step explanation:
The general formula for exponential growth is;
P= a(1 + r)^t
Where;
P = total number infected after a given time interval
a = initial number of infected people
r = growth rate of infection
x= time taken in weeks
Hence;
5000= 10(1 + 1.78)^t
5000/10 = (1 + 1.78)^t
500 = (1 + 1.78)^t
log 500 = tlog(1 + 1.78)
t = log 500/log(1 + 1.78)
t = 2.699/0.444
t = 6 weeks
The virus is spreading the fastest approximately 5.0 weeks after the jump.
What is exponential?An exponential equation is an algebraic expression that has an equality and at least one unknown in one of its exponents. To be considered an equation, an expression must have at least one unknown, which is an unknown number represented by a letter, and an equality relationship.
The general formula for exponential growth is;
P= a(1 + r)^t
Where;
P = total number infected after a given time interval = 5000a = initial number of infected people = 10r = growth rate of infection = 1.78x= time taken in weeksHence;
[tex]5000= 10(1 + 1.78)^t\\5000/10 = (1 + 1.78)^t\\500 = (1 + 1.78)^t\\log 500 = tlog(1 + 1.78)\\t = log 500/log(1 + 1.78)\\t = 2.699/0.444\\t = 6 weeks[/tex]
[tex]t=6-1=5 weeks[/tex]

(08.03)Consider the following pair of equations: y = −2x + 8 y = x − 1 Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answers
Answer:
[tex](3,2)[/tex]
Step-by-step explanation:
The method of variable substitution is a way of solving a system of equations. It involves solving one equation for a variable and then substituting in the expression that represents the value of the solved variable into the other equation. After doing so, one can solve for the unknown variable and then backsolve for the other variable.
[tex]y=-2x+8\\y=x-1[/tex]
In this system, the second equation is already solved for (y), thus one can substitute that expression into the other equation in the system.
[tex]x-1 = -2x + 8[/tex]
Now solve using inverse operations,
[tex]x -1 = -2x + 8\\+2x\\\\3x - 1 = 8\\+1\\\\3x =9\\/3\\\\x = 3[/tex]
Backsolve to find the value of (y), substitute in the value of (x), and solve for the value of (y).
[tex]y=x - 1\\[/tex]
Substitute,
[tex]y=(3)-1[/tex]
Solve,
[tex]y=2[/tex]
Thus, the answer to this system of equations is the following, [tex](3,2)[/tex].
Answer:
(x = 3 and y = 2)
Step-by-step explanation:
Ok, we have our 2 equations...
y = -2x + 8
y = x - 1
Lets solve them
y = -2x + 8 , y = x - 1
They both equal y so I can put them together to equal out. Now our equation is...
x - 1 = -2x + 8
The next step is to get x on one side by itself, so change the negative symbol on -2 to addition...
3x - 1 = 8
Next step is to add 1 on both sides...
3x = 9
Divide both sides by 3...
x = 3
Now to do the other equation, which is easier.
y = x (3) - 1
or
y = 2
Both are solved and we have ...
(x = 3 and y = 2)
