Answer:
ln 27x²
Step-by-step explanation:
Using the rules of logarithms
• log ⇔ nlogx
• logx + logy ⇒ logxy
Given
3 ln 3 + 2 ln x, then
= ln 3³ + lnx²
= ln 27 + lnx² = ln 27x²
The area of a rectangle is 294.4 sq.cm. The length of one side is 16cm. What is the perimeter?
2 answers:
the perimeter is 68.8cm
Ok so because this is a rectangle the line directly across (paralell) is equal, so if one line is 16cm, the line parallel to that will also be 16. Then the formula for area is LxW we'd plug in the numbers we know to get 294.4 =16 x W
then we divide 16 by both sides to make it even to get 18.4cm=W. Now we just plug everything in to the perimeter by doing 16 x 2 + 18.4 x 2 to get

Answer:
Step-by-step explanation:
Recall, if we have a polynomial of the form , then we say that a is a zero of multiplicity k and b is a zero of multiplicty m. For example, in the polynomial of the form
-5 is a zero of multiplicity 10 and 2 is a zero of multiplicity 3. If we want to know the degree of the polynomial, just add the multiplicity of both zeros (13 in our example).
In this case, we know that the degree of our polynomial should be at least 3(multiplicity 2 and multiplicity 1). So, lets take the polynomial of the form
.
In here, a is a zero with multiplicity 1 and b is a zero with multiplicity 2. We are also given that
.
Which implies that . Since the square of any number is a positive number, it must happen that a>0. So, we have that
.
We can choose any value of a and solve for b. Let us choose a=4. So we can have b=1/2 or b=-1/2. Let's use b=1/2. So our polynomial would be
which we can easily check that f(0)=-1.
