The period is 2.
Normally the period of sin(x) is 2pi, but the pi inside the sin(pix) 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.

Answer:
26.4 and 47.4
Step-by-step explanation:
When rounding to the tenth place value, you look at the number and determine what criteria it falls in.
If this number is 5 or higher, you raise the value of tenths place value by 1.
If this number is 4 or lower, you leave the value of the tenths place value what it originally is.
In this case, the number given is 26.425.
The tenths place value is 4. This number is not 5 or higher, so we do not raise it and we keep the number the same. So, it is 26.4.
The other problem is 47.546.
The second number right of the decimal point is 4. This number is not 5 or higher, so we do not raise it and we keep the number the same. So it is 47.5
