N=1500(2^018t), t≥0 Find the initial number of cells (N) in the culture, given the exponential function.

adelina 88 [10]

Answer:

1500

Step-by-step explanation:

Step 1: Understand what the question is asking you

It wants to know how much cells do you start off with or in other words how much cells are in the culture when time is 0

Step 2: Set t = 0

$N = 1500(2^{0.18(0)} )$

Step 3: Solve for N

$N = 1500(2^{0.18(0)} )$

$N = 1500(2^{0} )$

$N = 1500(1 )$

$N = 1500$

Therefore when the initial amount of cells there in the culture is 1500

The sum of two consecutive odd integers is 244244. Find the two integers.

lubasha [3.4K]

Let one of the integers be x

Other integer = x + 2

x + x +2 = 244244
2x = 244242
x = 122121

x + 2 = 122123

Thus the two integers are 122121 and 122123

The price of a cell phone call costs $4.35 for 3 minutes. How much would a 20-minute call cost?

musickatia [10]

It would equal 29$ dollars because you divide 20 and 3, and with that answer you multiply by 4.35 :)
