Identify the number that does not belong -10/2, -13.4, 22.continuing 7

1 answer:

4 0

If we are going to simplify the first number by dividing the given numerator by the denominator, we will get an answer of -5. This number and the second one are examples of rational number for they can be easily expressed as quotient of two number. However, the third one is irrational due to the repeating number 7 after the decimal point. Therefore, the answer is the third choice.

If cos(θ)=2853 with θin Q IV, what is sin(θ)?

marysya [2.9K]

Answer: $\sin \theta=\frac{-45}{53}$

Step-by-step explanation:

Since we have given that

$\cos\theta=\frac{28}{53}$

And we know that θ is in the Fourth Quadrant.

So, Except cosθ and sec θ, all trigonometric ratios will be negative.

As we know the "Trigonometric Identity":

$\cos^2\theta+\sin^2\theta=1\\\\\sin \theta=\sqrt{1-\cos^2\theta}\\\\\sin \theta=\sqrt{1-(\frac{28}{53})^2}=\sqrt{\frac{53^2-28^2}{53^2}}\\\\\sin \theta=\sqrt{\frac{2025}{53^2}}\\\\\sin \theta=\frac{45}{53}$

It must be negative due to its presence in Fourth quadrant.

Hence, $\sin \theta=\frac{-45}{53}$

Solve for p if 2|p| = 4 {-2, 2} {-4, 4} {-8, 8}

garri49 [273]

The answer is {-2, 2}, first you get p by itself by dividing 4 by 2. Then you have <span>|p| = 2, so p can be -2 or 2.</span>
