Use B=P(1+r/n) to find out the balance in marks account if he deposited 1950.00 at 2% Compounded daily for 4 years

andre [41]

Answer: $2112.40

Step-by-step explanation:

r = 0.02 (2%)

n = 365 (daily for a year)

p = 1950

You wrote the formula wrong too:

B = P x (1+r/n)^nt

t = 4

B = 1950 x 1.08...

B = $2112.40

A bacteria culture contains 1500 bacteria initially and doubles every hour. (a) Find a function N that models the number of bact

Tpy6a [65]

Answer: a) $N(t)=1500(2)^t$

b) 25165824000

Step-by-step explanation:

The exponential equation for growth is given by :-

$y= ab^t$ , where a= initial value , b =multiplicative growth factor and t = time.

Given : A bacteria culture contains 1500 bacteria initially and doubles every hour.

i.e. a = 1500 and b= 2

Then, the function N that models the number of bacteria after t hours will be :

$N(t)=1500(2)^t$

To find , the number of bacteria after 24 hours , we put t= 24 in above equation , we get

$N(24)=1500(2)^{24}\\\\=1500(16777216)=25165824000$

Hence, the number of bacteria after 24 hours is 25165824000.
