Answer:

≈ 1468.59223 in squared

Step-by-step explanation:

1) A=2AB+(a+b+c)h

2) AB= square root of s(s﹣a)(s﹣b)(s﹣c)

3) s=a+b+c / 2

4) A=ah+bh+ch+1 / 2 square root of﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4

5) 18·22+18·22+18·22+1 / 2 x the square root of ﹣184+2·(18·18)2+2·(18·18)2﹣184+2·(18·18)2﹣184≈1468.59223

≈ 1468.59223 in squared

In ideal conditions, 200 colony-forming units (cfu) of E. coli can grow to 400 cfu in 20 minutes, to 800 cfu in 40 minutes, and

kvasek [131]

Answer:

(a)Yes, it is an exponential function.

(b) $P(t)=200\cdot 2^{t/20}$

Step-by-step explanation:

(a)A population grows exponentially if it increases by a common ratio(called the growth ratio). We can see from the given information that the population of E.coli doubles every 20 minutes, therefore it is an exponential growth with a growth ratio of 2.

(b)The population, P(t) at any time t of an initial population, $P_o$ with a growth ratio of r over a period k can be modeled using the function:
