In another experiment, isabella starts with 10 bacteria of the same type, so their population increases by 20% each day. the expression 10(1 + 0.2)d finds the number of bacteria after d days. which statement about this expression is true? a) it is the sum of the initial population and the growth factor after d days. b) it is the product of the initial population and the growth factor after d days. d) it is the sum of the initial population and the percent increase. c) it is the initial population raised to the growth factor after d days.

B) It is the product of the initial population and the growth factor after d days.

Step-by-step explanation: Given initial number of bacteria  = 10.

Rate of increase = 20% each day = 0.2 .

Expression for finding the number of bacteria after d days is given by

, where d is the number of days.

We can see than initial population of bacteria is 10 and 10 is being multiplied with growth factor (1 + 0.2) after d days.

Therefore, correct option is B option.

B) It is the product of the initial population and the growth factor after d days.

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.
