hi
Step-by-step explanation:
The period of the y=1/2 sin (2x)-3 is 2.
We have given that,
y=1/2 sin (2x)-3
We have to determine the period
<h3>
What is the period?</h3>
A period is the part of the menstrual cycle when a woman bleeds from her vagina for a few days.
Normally the period of sin(2x) is 2x, but the pi inside the sin(2x) is a horizontal compression by a factor of 1/pi.
So 2pi·1/pi = 2
The 1/2 and -3 do not impact the period. Those just impact the amplitude (vertical aspect) of the graph.

The second choice is the right answer
To evaluate the expression we proceed as follows;
(7x³-16x+8)-(4x³-6x²+8x-9)
opening the parenthesis we have:
7x³+0x²-16x+8-4x³+6x²-8x+9
putting like terms together we get:
(7x³-4x³)+(-16x-8x)+(8+9)+(0x²+6x²)
=3x³+6x²-24x+17
the answer is
=3x³+6x²-24x+17
