What are trigonometric ratios ?

"The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.

The values of cot theta is undefined for $n\pi$ .

So, 0 , pi , 2pi , 3pi .....npi.

Hence C and D are correct option.

(461065) João Augusto lança uma bola para cima e ela descreve uma trajetória vertical. Os instantes de tempo em que a bola sai e retorna à mão de João Augusto são representados pelas raízes da equação – 5t² + 40t = 0. Durante quantos segundos a bola permaneceu no ar?

Final answer:

João Augusto's ball remained in the air for 8 seconds. This was determined by the roots of the equation -5t² + 40t = 0, which represents the ball's vertical trajectory.

Explanation:

The equation given in the question represents the motion of the ball thrown into the air. Specifically, it is a parabolic equation which describes the motion of an object under the influence of gravity. We can determine the duration of the ball's flight by finding the roots of this equation.

The equation -5t² + 40t = 0 can be factored into -5t(t - 8) = 0. Therefore, the roots of this equation are 0 and 8, which represent the instants of time. In this case, t = 0 is the time when João Augusto launched the ball, and t = 8 is the time when he caught it again.

So, the ball remained in the air for 8 seconds.

A computer simulation tossed a 10-faced die 5 times. How many possible outcomes exist?

Answers

Answer: There exists 100000 possible outcomes.

Step-by-step explanation: Given that a computer simulation tossed a 10-faced die 5 times.

We are to find the number of possible outcomes that exists.

Since there are 10 faces of the die, so we have 10 possible options for each of the 5 tosses.

Therefore, the total number of possible outcomes is

$n=10*10*10*10*10=10^5=100000.$

Thus, there exists 100000 possible outcomes.

What is a Quadratic Equation?

In algebra, a quadratic equation is any equation that can be rearranged in a standard form where x represents an unknown, and a, b, and c represent known numbers, where a ≠ zero.

Conclusion: If a = zero, then the equation is linear, no longer quadratic, as there's no ax^2 term.
