Aand b are natural numbers. the diameter of the cell is 2.3 10 exponent - a and the diameter of the cell b is 2.3 10 exponent -b. which is a true statement?
a. if a = 4 and b = 6, then cell a is 100 times greater than cell b.
b. if a = 4 and b = 6, then cell b is 100 times greater than cell a.
c. if a = 4 and b = 6, then cell a is 2 times greater than cell b.
d. if a = 4 and b = 6, then cell b is 2 times greater than cell a.

i think a?quick!

Determine the difference: 3.2 × 1010 – 1.1 × 1010. write your answer in scientific notation.

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
