Answer: 2560
< 98415
Step-by-step explanation:
The number of cells increase in an exponential growth, which is, in general:
A(t) = A₀.
where;
A is the growth at a time "t"
A₀ is the initial amount of cells
k is rate of growth
t is time in minutes
To write an equation for the conditions described above, we have to find the rate k, knowing that at every 2 minutes, the number of cells increases by 50%, i.e., A₀*1.5:
A(2) = 2560
2560*1.5 = 2560
= 1.5
ln() = ln(1.5)
k = 0.2027
With the initial value, the rate and knowing that the number of cells has to be less than 98415:
2560 < 98415
<u>The inequality in terms of t is 2560</u><u> < 98415</u>
Answer:
1
Step-by-step explanation:
- (-10÷(-1)+(-9))2nd power
- (10-9)2nd power
- 1 2nd power
4x + 8y = 20
- 4x + 2y = -30
find y first
in order to find y eliminate x
add the two equations together
4x+-4x+8y+2y= 20+-30
4x-4x+8y+2y= 20-30
10y= -10
divide both sides by 10 to get y by itself
10y/10= -10/10
y= -1
find x by using the substitution method
- 4x + 2y = -30
-4x+2(-1)=-30
-4x-2= -30
move -2 to the other side
sign changes from -2 to +2
-4x-2+2= -30+2
-4x= -28
divide both sides by -4
-4x/-4= -28/-4
x= 7
