Answer:

C. It represents the product of two rational numbers and its equivalent to a rational number.

Step-by-step explanation:

5 is a natural number, a real number and a rational number.

$\frac{1}{4}$ is a real number and a rational number.

The product of 5 × $\frac{1}{4}$ = 1.25 which is also a rational number in addition to being a real number.

Answer:

The correct answer is option C.

Step-by-step explanation:

It s given that 5 * 1/4

<u>To find the correct answer</u>

The given expression is 5 * 1/4

Here 5 is a rational number and 1/4 is a rational number

5 * 1/4 = 5/4

The number 5/4 is a rational number.

5/4 represents the product of two rational numbers and is equivalent to a rational number.

Therefore the correct answer is option C

Which value of x does not satisfy the equation sin^2x + sin x = 0

zzz [600]

Answer:

$x \neq 0 \pm \pi \cdot i, \forall i \in \mathbb{N}_{O}$ and $x \neq \frac{3\pi}{2}\pm 2\pi \cdot j, \forall j \in \mathbb{N}_{O}$ .

Step-by-step explanation:

The equation can be simplified with the help of trigonometric identities:

$\sin x \cdot (\sin x + 1) = 0$

Which means that equation is equal to zero if any component of the product is zero. The solutions of the expression are:

a) $\sin x$

$x = 0 \pm \pi\cdot i,\forall i \in \mathbb{N}_{O}$

b) $\sin x + 1$

$\sin x + 1 = 0$

$\sin x = -1$

$x = \frac{3\pi}{2} \pm 2\pi\cdot i,\forall i \in \mathbb{N}_{O}$

Any value different of both subsets do not satisfy the equation described above.

Not all of the student body would have responded therefore her conclusion was incorrect, could be changed to be right by saying 90% of people who responded to a survey said the school colours should be changed.
