Answer:
537 students
11 days
Step-by-step explanation:
5000
y= -----------------
(1+4999e^-0.8t)
a) after 8 days means t =8
5000
y= -----------------
(1+4999e^-0.8*8)
5000
y= -----------------
(1+4999e^-6.4)
5000
y= -----------------
(1+8.306)
5000
y= -----------------
(9.306)
y =537.28
Rounding to the nearest student
y = 537 students
b) 1/2 the student population means y =2500 (The 5000 is the student population)
5000
2500= -----------------
(1+4999e^-0.8t)
Multiply each side by (1+4999e^-0.8t)
2500 (1+4999e^-0.8t) = 5000
Divide each side by 2500
(1+4999e^-0.8t) = 5000/2500
(1+4999e^-0.8t) = 2
Subtract 1
(4999e^-0.8t) = 2-1
(4999e^-0.8t)=1
Divide by 4999
(4999/4999e^-0.8t)=1/4999
e^-0.8t=1/4999
Take the natural log of each side
ln(e^-0.8t)=ln(1/4999)
-.8t = ln(1/4999)
Divide by -.8
-.8/-8t = -1/.8 *ln(1/4999)
t = -1/.8 *ln(1/4999)
t≈10.6462
Rounding, it will take 11 days
Answer: hold on you didn’t give enough info for this to make sense
Step-by-step explanation:
I forgot the name, but there is a theorem that states that those two angles are equal. So if you do 94=5x+4 , you can solve that.
94=5x+4.
Subtract 4 from both sides
90=5x
Divide both sides by 5
18=x
Hope this helps :)
The total number of copies that have been sold till date are: 517284
Step-by-step explanation:
Let x be the total number of copies sold
Then
41900 is 801 percent of x
This can be mathematically written as

Rounding off to nearest whole number
517284
Hence,
The total number of copies that have been sold till date are: 517284
