Answer:
ALL the Highlighted ones? or everyone on the page? For the Highlighted ones I got 25 1/2 Evaluated is 51/2 in exact form in decimal form it is 25.5 and as a mixed number it is 25 1/2. 81 3/4 I got 327/4 in Decimal form I got 81.75 and in Mixed number form I got 81 3/4. Hope this helped!
Step-by-step explanation:
2:3:4
Shortest is clearly 2
(2×7.5):(3×7.5):(4×7.5)
So the sides are 15 , 22.5 and 30
Perimeter = 15 + 22.5 + 30
Perimeter = 67.5
Answer:
#1) A. 4; #2) A. periodic; about 6; #3) B. not periodic; #4) C. 2; 0.5; #5) A. 0.05 seconds; 4.5.
Explanation:
#1) The period of a function is essentially the amount of time it takes for the function to start all over and repeat itself. In this function, at t = 0 the graph is at 1; it curves up, back down and begins again at y=1 when t=4. This means the period goes from t=0 to t=4, so it is 4.
#2) Looking at the left side of the graph, specifically the peak at (-5, 2), we see the same peak at about (1, 2). Following the graph after that we can see that it does indeed repeat itself; this means the period goes from t= - 5 to t = 1, so it is 6.
#3) This function never repeats, so it is not periodic.
#4) This function repeats when it reaches t=2, so 2 is the period. The amplitude is the distance from the center line (of the graph, not the x-axis) to the peak. The center line would be located at about y=0.5; the peaks are at y=-1. This means the amplitude is 0.5.
#5) This function repeats every 0.05 seconds. In this case, the center line is the x-axis; the distance from it to any peak is 4.5, so 4.5 is the amplitude.
