A scientist initially measures 6,000 bacteria in a growth meditim. 7 hours later, the scientist measures 12,000 bacteria. Assuming exponential growth, the formula P = C(2)" gives the
number of bacteria in the growth medium, where r and C are constants and P is the number of
bacteriat hours after the initial measurement. What is the value of r?

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

283 square feet

step-by-step explanation:

good luck

9 x 8 divided by (5-3)=36

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
