A and B both correct
Answer:
x=1
Step-by-step explanation:
Step 1:Simplify both sides of the equation
4(x-5)+2x=-14
(4)(x)+(4)(-5)+2x=-14
4x+-120+2x=-14
4x+2x+-20-14
6x+-20=-14
6x-20=-14
Step 2: Add 20 to both sides
6x-20+20=-14+20
6x=6
Step 3: Divide both sides by 6
6x/6=6/6
x=1
Answer:
Beginning (t=0) population with flu is 23.
After 4 weeks, population with flu is 1250.
After an infinite amount of weeks, the population witf flu is 102000
Step-by-step explanation:
First question asks you to replace t with 0 because it says beginning.
102000/(1+4400e^-0)=102000/(1+4400)=102000/4401=23.17655 approximately. To nearest whole number this is 23.
After 4 weeks means we replace t with 4:
102000/(1+4400e^-4)
Calculator time:
1250.17142 which to nearest whole number is 1250
If t is super large, then e^-t is super close to 0.
So the limiting number is
102000/(1+4400×0)=102000/1=102000
Volume=904.78
Surface Area=452.39
