Can you fine the cube root of a negative number? If so, is it positive or negative? Explain your answer.

Nata [24]

Answer:

Yes, you can find the cube root of a negative number. The answer will be negative!

Step-by-step explanation:

Example: Find the cube root of -27

We know that a cube root is a number multiplied by itself 3 times (NOT MEANING THE NUMBER TIMES 3)

For example, The cube root of 27 positive is 3 because 3 x 3 x 3 = 27

But if we are using a negative number: It is really different because we got to know the rules.

The setup: -3 x -3 x -3 = -27

If we started with -3 x -3 first we know that a negative times a negative equals positive so the answer will be 9 positive, then we have this equation left:

9 x -3 = -27

The rule with this is a number times a negative is negative, so the answer of the question "Find the cube root of -27 is -3"

Please help emergency

Firdavs [7]

Step-by-step explanation:

This is a probability related problem.

Probability is the likelihood of an event to occur;

Pr = $\frac{number of possible outcomes}{Total sample space}$

The sample space here is from 1 to 25 which is 25

Pr of a card marked 8; we have just 1 possible outcome;

Pr(8) = $\frac{1}{25}$

Pr of drawing a card that is a multiple of 5;

Multiples of 5 = 5, 10, 15 and 25

Pr (multiples of 5) = $\frac{4}{25}$

Pr of drawing a card with odd numbers:

Number of odd numbers between 1 and 25 = 13

Pr(odd numbers) = $\frac{13}{25}$

Pr of drawing a number with square number on it;

Square numbers between 1 and 25 = 1, 4, 9, 16 and 25

Pr(square numbers) = $\frac{5}{25}$ = $\frac{1}{5}$

Write an equation to represent the measures of the angles

marin [14]

Answer:

x = 72

Step-by-step explanation:

These angles are complementary so they add up to 90:

x + 18 = 90

x = 90 - 18

x = 72
