The amount of bacteria in a petri dish increases at a rate proportional to the amount present. At time t=0, the amount of bacter
Lilit [14]

Answer:

Step-by-step explanation:

Formula to be used is N=N0e^(kt)

N0 - amount of bacteria at time 0, which is 10g

t=2, 30g

30 = 10*e^(k*2)

3 = e^(2k)

2k = ln3

k = 0.5ln3

At t=6:

N = 10*e^(0.5ln3*6)

N = 10e^(3ln3)

N = 10e^ln27

N = 10*27 =270

So the amount of bacteria at t=6 is 270

What is the solution to the equation 93x ≈ 7?
s344n2d4d5 [400]
Well, I do not know if you mean 93x = 7 or 9^3x = 7.
So, I will provide the solution for both cases.

In case of 93x = 7:
This case is simple, all you have to do is isolate the x. You need to get rid of the coefficient which is 93. You can simply do this by dividing both sides of the equation by 93 as follows:
93x = 7
93x / 93 = 7/93
x = 7/93

In case of 9^3x = 7:
Now, we need to get rid of the power. The only function that can do this is the log function.
So, we will start by taking log base 10 for both sides of the equation as follows:
9^3x = 7
log(9^3x) = log(7)
This will give:
3x * log(9) = log(7)
Now, the final step is to isolate the x as we did before. To do this, we will need to get rid of 3log(9). This can be done by dividing both sides of the equation by 3log(9) as follows:
3x * log(9) / 3log(9) = log(7) / 3log(9)
This will give us:
x = log(7) / 3log(9) = 0.2952

Hope this helps :)

Solve the inequality <br> 3y &lt;= 2y + 3
Volgvan

Answer:

y\leq 3

All real numbers less than or equal to 3

Step-by-step explanation:

we have

3y\leq 2y+3

Solve for y

Subtract 2y both sides

3y-2y\leq 2y+3-2y

y\leq 3

The solution is the interval ------> (-∞,3]

All real numbers less than or equal to 3

In a number line the solution is the shaded area down of y=3 (close circle)

see the attached figure
