Answer: a^3+81ab^2
First, you square (a+9b) which will become (a^2+81b^2)
Then, you multiply it by a and you will get a^3+81ab^2
Answer: 1.73205080757
Step-by-step explanation: The square root of 3 is the positive real number that, when multiplied by itself, gives the number 3. It is more precisely called the principal square root of 3, to distinguish it from the negative number with the same property. It is denoted by √3. The square root of 3 is an irrational number.
Answer:
a. 1,2,3
Step-by-step explanation:
Answer: False.
Step-by-step explanation:
This says;
If we have an interval I, f(x) is increasing if, for any two x1, x2 such that:
x1 ∈ I and x2 ∈ I.
where x2 > x1, ----> f(x1) > f(x2).
An increasing function means that, if the value of x increases, also does the value of f(x).
Particularly, here we have that x2 > x1
so x can increase from x1 to x2.
But we have that f(x1) > f(x2)
So here we can see that the actual value of f(x) decreases as x increases.
Then this is not a increasing function, so the statement is false.
