87. a scientist is studying the growth of a population of bacteria. at the beginning of her study, she has 800 bacteria. she notices that the population is quadrupling every hour.
a. what quantities, including units, need to be identified to further investigate the growth of this bacteria population?

Explained

Step-by-step explanation:

A scientist is studying the growth of a population of bacteria. At the beginning of her study, she has 800 bacteria. She notices that the population is quadrupling every hour.

We need to know the initial population P__0, in either units of single bacteria or hundreds of bacteria, the time t, in hours , the current population P(t) at a time t, in the same units as initial population P_o.

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
