Answer:
u = 
Step-by-step explanation:
Since u varies inversely as s³, then
u ∝ 
To convert to an equation multiply by k the constant of variation
u = k ×
= 
M=1 so you do 2m+7-7=9-7
2m/2=2/2 and you get m=1
Model:
number of hours number of bacteria
0 75000
4*1 75000 / (2^1)
4*2 75000 / (2^2)
4*3 75000 / (2^3)
4*4 75000 / (2^4)
4*n 75000 / (2^n)
=> 2000 = 75000 / (2^n)
=> 2^n = 75000 /2000
= 2^n = 37.5
=> n log(2) = log (37.5)
=> n = log (37.5) / log (2)
=> n = 5,2288
=> 4*n = 20.91
Answer: approximately 21 hours.
Answer:
Route A is 0.75 km longer than route B.
Step-by-step explanation:
Length of route A is 1.5 times the length of route B.
a = 1.5b

--------(1)
Here, a = Length of route A
b = Length of route B
Length of route A is
of route C.
a = 
------(2)
Here, c = Length of route C
Length of route C = 3 km
Length of route A =
[From equation (2)]
= 2.25 km
Length of route B =
[From equation (1)]
= 1.5 km
Difference in route A and route B = 2.25 - 1.5
= 0.75 km
Therefore, route A is 0.75 km longer than route B.
