Answer:
the number of bacteria increases at a rate of 15% each day
Step-by-step explanation:
Given the function :
f(x) = 256(1.15)^x
The function represents an exponential growth function ; comparing the equation with the general form of an exponential growth function :
f(x) = A(1 + r)^t
A = the initial value of the population, = 256
(1 + r),; r = growth rate
Therefore, to solve for r ;
1 + r = 1.15
r = 1.15 - 1 ; r = 0.15
Hence, growth rate = 0.15 = 0.15 * 100% = 15%
Hence, the number of bacteria increases at a rate of 15% each day
It has 3 sig figs because 0 is not significant in this case because it’s at the end
Answer:
the corn on the cobs cost $9 and the hamburgers cost $25 so the total cost is $34
Step-by-step explanation:
c = 2 because Carmel apples cost 2 dollars and c represents $2
corn on the cobb: 2 + 1 = 3 mark is buying 3 corns so 3+ 3+ 3=9
hamburgers: 2 + 3 = 5. mark is buying 5 hamburgers so 5+5+5+5+5=25
25 + 9 = 34
