What sine function represents an amplitude of 4, a period of pi over 2, no horizontal shift, and a vertical shift of −3?
mixer [17]

Answer:

f(x) = 4sin(\frac{\pi}{2}x) - 3, the third one

Step-by-step explanation:

Explaining the sine function:

The sine function is defined by:

S = Asin(p(x - x_{0})) + V

In which A is the amplitude, p = \frac{2\pi}{N} is the period, x_{0} is the horizontal shift and V is the vertical shift.

So, in your problem:

The amplitude is 4, so A = 4.

The period is \frac{\pi}{2}, so p = \frac{\pi}{2}.

There is no horizontal shift, so x_{0} = 0.

The vertical shift is −3, so V = -3.

The sine function that represents these following conditions is

f(x) = 4sin(\frac{\pi}{2}x) - 3, the third one

Answer:

EBC and ABE, as well as ABD and ABE

Step-by-step explanation:

Supplementary angles form an 180 degree angle. In other words, they form a straight line.

EBA and DBC are each greater than 90 degrees and are vertical angles, not supplementary angles.

EBC and ABE form a straight line. So they are supplementary angles.

ABD  and ABE form a straight line. So  they are also supplementary angles.

CBE and ABD are each less than 90 degrees and are vertical angles, not supplementary angles.

So, EBC and ABE, as well as ABD and ABE are the correct choices.
