Jacinta says that the product of a rational number and an irrational number is always irrational. Explain her error.

Answers

Answer 1
if u multiply an irrational number by 0 the result will be 0 which is a rational number. Except this case, other times will result with irrationals.
Answer 2

Jacinta says that the product of a rational number and an irrational number is always irrational her claim is wrong.

What is a rational number?

A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.

Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers. Decimal notation is the term used to describe the method of representing numbers in the decimal system.

Given that Jacinta says that the product of a rational number and an irrational number is always irrational.

Her statement is incorrect because if 0 a rational number is multiplied with the π which is irrational then the result will be 0 which is rational.

Therefore, Jacinta's claim is wrong.

Answers

The - change every sing -m-3n+12

Answer:

-m - 3n + 12

Step-by-step explanation:

Because we don't know the values of "m" and "n"  the simplest form you can get the equation to be is -m + - 3n + 12

That is because with a negative in front of the parenthesis it's like multiplying by negative 1. So -1 x m, -1 x 3n, and -1 x -12.

Answers

f(4)=3(4)+5
12+5
f(4)=17

Answer:

             f(4) = 17

Step-by-step explanation:

Given function f(x), when you want to find f(4) you just put 4 for every x in the equation of the function.

f(x) = 3x + 5    ⇒    f(4) = 3(4) + 5 = 12 + 5 = 17

g(x) = 2x² - 4   ⇒    g(4) = 2(4)² - 4 = 2•16 - 4 = 32 - 4 = 28

h(x) = -3x - 9   ⇒    h(4) = -3(4) - 9 = -12 - 9 = -21

Answers

Answer:

subtract 2.9 from 3.8 you get 0.9

subtract 1.0 from 1.9 you get 0.9

subtract 1.9 from 2.8 you get 0.9

subtract 1.8 from 2.9 you get 01.1

I would say that your answers are E, C, and B.

Answer:

B, C, and E

Step-by-step explanation:

If you subtract 2.9 from 3.8 you get 0.9 so if u apply that to B, C, and E, you could add 0.9 to 0, 1.0, and 1.9 and get the equations:

0+0.9= 0.9

1.0+0.9= 1.9

1.9+0.9= 2.8

so as you can see it all just increases by 0.9 every time.
