Answer:
The answer is C
Step-by-step explanation:
First of all let's eliminate the answers that do not make sense. For A. numbers are NOT irrational because they are a fraction. Numbers are also not irrational because they are a repeating number. C and D are both correct as fractions and terminating decimals are both rational numbers.
34/3≈11.33333333
By using a certain formula you can convert repeating decimals to a fraction. But most people know that .3333333 is 1/3. This gives us 11 1/3 as our answer. So what does it match? It is not a terminating decimal. It repeats but can be written as a fraction. Therefore our answer is C) Rational, because it is a fraction.
Answer:
The answer is n + 3.
Step-by-step explanation:
1) Simplify.

2) Factor out the common term 2.

3) Cancle 2.

Answer:
The value of f(3) is -2.
Step-by-step explanation:
This is a recursive function. So

Now, we find f(2) in function of f(1). So


Now, with f(2), we can find the value of f(3).


The value of f(3) is -2.
Answer: the length of the ladder is 40 meters.
Step-by-step explanation:
The ladder forms a right angle triangle with the wall and the ground.
The length of the ladder represents the hypotenuse of the right angle triangle.
The distance of the base of the ladder due west of the burning building represents the adjacent side of the right angle triangle.
To determine the length of the ladder, h, we would apply the cosine trigonometric ratio. It is expressed as
Cos θ = adjacent side/hypotenuse. Therefore,
Cos 51 = 25/h
h = 25/Cos 51 = 25/0.6293
h = 40 meters to the nearest meter.
