Answer:
x(t) = 2000 - e^(-k*t)
Step-by-step explanation:
Interpretation:
No . infected student = x
Total student = 2000
rate of infected students = dx / dt
not-infected student = 200 - x
The general rate at which student are infected can be expressed as below:
dx / dt = k * ( 2000 - x )
To develop an expression of x(t) we integrate the above expression by separating variables:
dx / (2000 - x ) = k * dt
Now integrate:
@ t = 0 , infected students x = 0
Hence,
C = - ln (2000)

Answer: 10.2-11.8
Step-by-step explanation:
im guessing that the question is "write one expression that is equal to 5.1 - 5.9" i would make it simple as possible and double both numbers to get 10.2-11.8"
Answer:
They need to earn 6 yards on the fourth down to have a 10 yard gain from their starting position
Step-by-step explanation:
A football team gained 6 yards on the first down, lost 19 yards on the second down,
Total gained yards:
6 - 19 = -13 yards
So at the end of 2nd down the team lost 13 yards.
They gained 17 yards on the third down.
-13 + 17 = 4
So at the end of 3rd down the team gained 4 yards.
They want 10 yard gain at the end of 4th down.
If they gain 6 yards in the 4th down then the sum will be 10 yards
4 + 6 = 10
Hence, they need to earn 6 yards on the fourth down to have a 10 yard gain from their starting position.
Answer:
y= 2x -2
Step-by-step explanation:
You would use point- slope formula. y-y = m(x-x). With your numbers it would end up looking like this ----> y-6 = 2(x-4), then do the distributive property which then gives you ----> y-6 = 2x - 8, then subtract 6 on both sides and you get ---> y = 2x - 2. Hope this helped!!!!
