Why is the product of a rational number and an irrational number Irrational?

Llana [10]

Answer:

Because the product is always non-termination,non-repeating decimal.

Step-by-step explanation:

If we have $a$ is irrational; $b$ is rational such that $b \neq 0$ , then $a \cdot b$ is irrational.

A way to represent this is:

$a\in\mathbb{R}\setminus\mathbb{Q}, b\in\mathbb{Q},ab\in\mathbb{Q}\implies a\in\mathbb{Q}\implies\text{Contradiction}\therefore ab\not\in\mathbb{Q}.$

Note that we have a contradiction, because $a$ is not a rational number, as I stated in the beginning. Therefore, ab is irrational.

Easy Question. 4. In photo.

Luden [163]

Use the slope formula:

$\frac{y_2-y_1}{x_2-x_1}$

Plug in the values:

$\frac{2-(-5)}{4-0} = \frac{7}{4}$

So 7/4 is the slope.

Which of the following is information a basic loan application would not ask you for? a. name b. date of birth c. Social Securit

Dafna1 [17]

Answer: The answer is (D) auto insurance agency.

Step-by-step explanation: We are given four options out of which we are to select the one which a basic loan application would not ask us for.

We know that a basic loan application always needs to know some information like name, date of birth, social security number, address, etc.

What it does not need is auto insurance agency, because they do not need any information about this.

Therefore, the correct option is (d) auto insurance agency.

I need help please no links I will report

stellarik [79]

Answer: $1.45

Step-by-step explanation:

We start by subtracting the change from how much she payed for.

d = dollars | g = goldfish

$16d - 0.05d = 15.95d$

Then we divide by the goldfish

$\frac{15.95d}{11g} = 1.45d$

Our answer is 1.45!

Also, warning, the people who go into the comments saying to download something from bitly, do not do it. They are viruses and will not get the answer, please only report their answer and ignore them.

Sec theta - Csc theta / (csc theta)(sec theta)

Sophie [7]

Answer:

sin(x)-cos(x)

Step-by-step explanation:

$\frac{\frac{1}{cos(x)} - \frac{1}{sin(x)} }{\frac{1}{sin(x)} * \frac{1}{cos(x)} }$

Simplify the denominator:

$\frac{\frac{1}{cos(x)} - \frac{1}{sin(x)} }{\frac{1}{cos(x)sin(x)} }$

Simplify the numerator:

$\frac{{\frac{2(sin(x)-cos(x))}{sin(2x)} } }{\frac{1}{sin(x)} * \frac{1}{cos(x)} }$

Divide the fractions: (a/b)/(c/d) = (a * d)/(b * c):

$\frac{(-cos(x)+sin(x))*2cos(x)sin(x)}{sin(2x)}$

Use the identity: 2cos(x)sin(x) = sin(2x):

$\frac{sin(2x)(-cos(x)+sin(x))}{sin(2x)}$

Cancel out the common factor (sin(2x)):

-cos(x) + sin(x)

Simplify:

sin(x) - cos(x)
