Question:
(a) How many bacteria would be found in 24 hours
(b) How many bacteria would be found in 2 days
(c) How long for 1000 bacteria to be found
Answer:
(a) 282429536481 bacteria
(b)
bacteria
(c) 6 days
Step-by-step explanation:
The question illustrates an exponential function

Where

--- i.e. triples

Solving (a): Bacteria in 24 hours
In this case:

Substitute
,
and 
So:



bacteria
Solving (b): Bacteria in 2 days

So:

Substitute
,
and 
So:


bacteria
Solving (c): How long for 1000 bacteria
In this case:

Substitute
,
and 
So:



Take Log of both sides

This gives:

Make x the subject


<em>Hence: It takes 6 days</em>
Answer:

Step-by-step explanation:
The square root of 11 is 3.31... this could be the answer.
658 = 3.14 * r^2
<span>658 / 3.14 = r^2 </span>
<span>209.55 = r^2 </span>
<span>14.5 = r :)</span>
When a polynomial has more than one variable, we need to look at each term. Terms are separated by + or - signs. Find the degree of each term by adding the exponents of each variable in it. <span>The degree of the polynomial is found by looking at the term with the highest exponent on its variables.

Polynomials can be classified in two different ways - by the number of terms and by their degree.
A monomial is an expression with a single term. It is a real
number, a variable, or the product of real numbers and variables. A polynomial is a monomial or the sum or difference of monomials. A polynomial can be arranged in ascending order, in which the
degree of each term is at least as large as the degree of the
preceding term, or in descending order, in which the degree of
each term is no larger than the degree of the preceding term.
The polynomial

is classified as a 3rd degree binomial, because the monomial

has degree equal to 3 and the monomial 5xy has degree equal to 2. The highest degree is 3, therefore the polynomial

is classified as a 3rd degree polynomial. Since polynomial <span><span>

</span> has two terms, then it is classified as binomial.</span>
