Answer:
The bacterial culture loses 
of its size every 7 seconds.
Step-by-step explanation:
The relationship between the elapsed time t, in seconds, and the number of bacteria, N(t), in the petri dish is modeled by the function:
Since the growth factor is less than 1, it is a decay equation.
Observe that the time t is divided by 7.
This is the period.
We can therefore say that the bacterial culture loses of its size every 7 seconds.
Well there is no exact answer
Withdrawals are when cash is taken out from the account
Flora withdraws an amount of $75 at a time from her bank account
she makes 7 such withdrawals
one withdrawal she takes out - $75
then seven withdrawals leads to - $75 x 7 = $525
then overall change in her account has been a net withdrawal of $525
so the overall change in the account is -$525

hi
Step-by-step explanation:
i need this asnwer too
3 -
=
- 7
First, simplify
to
/ Your problem should look like: 3 -
=
- 7
Second, simplify
to
/ Your problem should look like: 3 -
=
- 7
Third, multiply both sides by 9 (the LCD of 9,3). / Your problem should look like: 27 - 2b = 3b - 63
Fourth, add 2b to both sides. / Your problem should look like: 27 = 3b - 63 + 2b
Fifth, simplify 3b - 63 + 2b to 5b - 63. / Your problem should look like: 27 = 5b - 63
Sixth, add 63 to both sides. / Your problem should look like: 27 + 63 = 5b
Seventh, simplify 27 + 63 to 90. / Your problem should look like: 90 = 5b
Eighth, divide both sides by 5. / Your problem should look like:
= b
Ninth, simplify
to 18. / Your problem should look like: 18 = b
Tenth, switch sides. Your problem should look like: b = 18
Answer:
b = 18
