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.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
