3 0

Answer:

Answers are below

Step-by-step explanation:

Hour 0 1 bacterium

Hour 1 3 bacterium

Hour 2 9 bacterium

Hour 3 27 bacterium

Hour 4 81 bacterium

Hour 5 243 bacterium

Hour 6 729 bacterium

After 24 hours, the number of the bacterium will reach 282,429,536,481.

B) This table represents exponential growth because of the number of bacterium always being multiplied by 3.

C) The reason that any number to the zero power is one is that any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.

D) Y = 1 + 3 to the power of x

E) The rule would change by having all of the numbers multiplied by 100 since there is 100 bacterium at Hour 0.

Which algebraic expression is a polynomial? 3m2n-2m/n+1/n

Lesechka [4]

Answer:

d) $7mn+\frac{3m}{2}+\frac{5n}{4}$

Step-by-step explanation:

Which algebraic expression is a polynomial?

$a)3m^2n-\frac{2m}{n}+\frac{1}{n} \\b)\frac{2mn}{5}-\frac{\sqrt{m} }{4} +4m^5\\c)\frac{4m^3}{n^2}-3mn^5+\sqrt{8}\\d)7mn+\frac{3m}{2}+\frac{5n}{4}$

Answer: A polynomial is an expression with variables and coefficients separated by addition and subtraction. The following are used when determining if an expression is a polynomial:

i) Variables of a polynomial must not have negative exponent.

ii) Variables of a polynomial must not have fractional exponent.

iii) Dividing by an exponent is not allowed

iv) Exponent radicals are not allowed.

a) $3m^2n-\frac{2m}{n}+\frac{1}{n}$ is not a polynomial because dividing by an exponent is not allowed.
