Answer:

The answer is C. Square root √18

Step-by-step explanation:

you are looking for irrational number.

if use a calculator and you see that the √18 is 4.242642687119285 is a non-terminated number and non-repeated number so its irrational

the other three is rational because you can turn them into a fraction and we don't want that.

If you spun the spinner 100 times, how many times do you predict that you would spin a number less than 5 on a spinner of 1-6
Roman55 [17]

Answer:

67 times

Step-by-step explanation:

Spinner's sample space = (1, 2, 3, 4, 5, 6)

Number less than 5 = (1, 2, 3, 4)

Total possible outcomes = 6

Required outcome = 4

P(number less than 5) = required outcome / Total possible outcomes

P(number less than 5) = 4 /6 = 2/3

Number of spins = 100

Predicted Number of times a number less than less than 5 is spurn in 100 spins :

100 * 2/3

= 66.666

= 67 times

Which is a factor of f(x) = 60x4 + 86x3 – 46x2 – 43x + 8? Use the Rational Root Theorem to help you find your answer.
Troyanec [42]

The rational root theorem is used to determine the possible roots of a polynomial

The factor of the polynomial function is: 6x – 1

<h3>How to determine the roots</h3>

The polynomial function is given as:

f(x) = 60x^4 + 86x^3 - 46x^2 - 43x + 8

Using the rational root theorem, the potential roots are:

Roots = \pm \frac{Factors\ of\ 8}{Factors\ of\ 60}

List the factors of 8 and 60

Roots = \pm \frac{1,2,4,6}{1,2,3,4,5,6,10, 12, 15, 20, 30,  60}

Simplify

Roots = \pm(1,1/2,1/3,1/4...1/60, 2,2/3,2/5...1/30)

Hence, the factor of the polynomial function is: 6x – 1

Simplify the expression.<br> 16n−16
Alex787 [66]

Answer:

16(n-1)

Step-by-step explanation:

16(n-1) is the simplest form of 16n-16 because you cannot backtrack any farther. To get to 16n-16, you must have 16(n-1) first. When you distribute, you will have 16n and -16. Put those into an equation, you get 16n-16 which is what you have originally.
