Idk if this wil help but...
Let speed of Matthew be X yards/min Speed of Lowe = 3X yards/min.
Distance covered by Matthew in 30 minutes = 30X
Distance covered by Lowe in 30 minutes = 30(3X)= 90X
90X = 30X + 1200 X = 20 yards/min

Answer:
7/3
Step-by-step explanation:
because (x,y) is the coordinates , 3/2 is y
y = 3/2
plug in y
x * 4 * 3/2 = 14
solve
x*6 =14
simplify
x= 14/6 = 7/3
so the pair went down from 200 to 140, so the difference is 200 - 140 = 60.
so if we take 200 as the 100%, what is 60 off of it in percentage?
The maximum value attained by the function will be 4
4 = 4cos(2x - π)
cos(2x - π) = 1
2x - π = 0
x = (nπ)/2
From x = 0 to x = 2π, n = 1, 2, etc
The equation will yield +4 for odd values of n and -4 for even values of n
