Remember that the domain is all possible x values of a function. In the case of sine and cosine functions, they go up and down (like waves), but go on forever. Therefore, the domain is all real numbers.

Correct Answer: B, All Real Numbers

Hope this helps!

<h3>Answer: B. All real numbers</h3>

Explanation:

For the equations y = sin(x) and y = cos(x), we can replace x with any real number we want. The output y value will be between -1 and 1, inclusive of both endpoints.

The graph for each function shows a bouncing wave stretching forever to the left and right. This visually confirms the domain.

Is ∆JKL ≅ ∆KJM ? Justify your answer below.

makkiz [27]

Answer:

Yes, the triangles are congruent by ASA

Step-by-step explanation:

we know that

If any two angles and the included side are the same in both triangles, then the triangles are congruent by Angle-Side-Angle (ASA)

In this problem

LK=MJ

∠KLJ=∠KMJ

∠LKJ=∠MJK

Two angles and the included side is equal in triangle JKL and triangle KJM

therefore

JKL≅KJM ----> by ASA

What is the equation of the line that passes through the points (-1 , 3/2) and (1/2 , 1/2 )

Simora [160]

Answer:

<u>y = -2/3x + 5/6</u> (slope intercept) (y = ax + b)

4x + 6y = 5 (standard form) (Ax + By = C)

y - 3/2 = -2/3(x + 1) (point slope) (y-y1 = m(x-x1)) (m = y2 - y1 / x2 - x1)
