The operation between a rational and a irrational number that results in a rational number is a multiplication, hence the expression ab could represent a rational number.

<h3>What are rational and irrational numbers?</h3>

If a number can be represented by a fraction, it is rational, otherwise, it is irrational.

The addition/subtraction of a rational and an irrational numbers is irrational, while the multiplication is rational, hence the expression ab could represent a rational number.

Calculate the simple interest rate. (Round your answer to one decimal place.)
GrogVix [38]

Answer:R = 9.1667%/year

Step-by-step explanation:

Solving our equation

r = 330 / (3600 × 1) = 0.09166667

r = 0.09166667

converting r decimal to a percentage

R = 0.09166667 × 100 = 9.1667%/year

The interest rate required to

accumulate simple interest of $330.00

from a principal of $3,600.00

over 1 years is 9.1667% per year.

Answer:

It has the same domain as the function f(x)=-\sqrt{-x}

Step-by-step explanation:

we have

f(x)=\sqrt{-x}

we know that

The radicand cannot be a negative number

so

-x\geq 0

Solve for x

Multiply by -1 both sides

x\leq 0

The domain of the given function is the interval ----> (-∞,0]

All real numbers less than or equal to 0

The range of the given function is the interval ----> [0,∞)

All real numbers greater than or equal to zero

<u><em>Verify each statement</em></u>

Part 1) It has the same domain as the function f(x)=-\sqrt{-x}

<em>The statement is true</em>

The domain of the function f(x)=-\sqrt{-x} is

the interval ---> (-∞,0]

Part 2) It has the same range as the function f(x)=-\sqrt{-x}

The statement is false

The range of the function f(x)=-\sqrt{-x} is

the interval ---> (-∞,0]

Part 3) It has the same domain as the function f(x)=-\sqrt{x}

The statement is false

The domain of the function f(x)=-\sqrt{x} is

the interval ---> [0,∞)

Part 4) It has the same range as the function f(x)=-\sqrt{x}

The statement is false

The range of the function f(x)=-\sqrt{x} is

the interval ---> (-∞,0]

Answer:

The answer to your question is x = 3; y = 3

Step-by-step explanation:

Data

angle = 45°

Opposite side = x

Adjacent side = y

hypotenuse = 3√2

To solve this problem, use trigonometric functions.

1) To find x, use the trigonometric function sine.

              sin Ф = Opposite side / hypotenuse

-Solve for Opposite side (x)

              Opposite side = hypotenuse x sin Ф

-Substitution

              Opposite side = 3√2 sin 45

-Simplification

               Opposite side = 3√2 (1 / √2)

               Opposite side = 3(1)

-Result  

               x = 3

2) To find y use the trigonometric function cosine

               cos Ф = Adjacent side / hypotenuse

-Solve for Adjacent side

                Adjacent side = hypotenuse x cos Ф

-Substitution

                Adjacent side = 3√2 x cos 45

-Simplification

                Adjacent side = 3√2 x (1/√2)

                Adjacent side = 3(1)

-Result

                y = 3
