A certain strain of bacteria is growing at a rate of 73% per hour, and with 5,000 bacteria initially, this event can be modeled by the equation B(t) = 5,000(1.73)t. With this fast growth rate, scientists want to know what the equivalent growth rate is per minute. Using rational exponents, what is an equivalent expression for this bacterial growth, expressed as a growth rate per minute? B(t) = 5,000(1.73)start fraction t over 60 end fraction
B(t) = 5,000(1.0092)60t
B(t) = 5,000(1.0092)t
B(t) = 5,000(1.73)t

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

maya’s expression will generate the wrong sum because she violated the commutative property.
