if there are 2 rows then each row will have 78 members
H(t) = -16t² + 60t + 95
g(t) = 20 + 38.7t
h(1) = -16(1²) + 60(1) + 95 = -16 + 60 + 95 = -16 + 155 = 139
h(2) = -16(2²) + 60(2) + 95 = -16(4) + 120 + 95 = -64 + 215 = 151
h(3) = -16(3²) + 60(3) + 95 = -16(9) + 180 + 95 = -144 + 275 = 131
h(4) = -16(4²) + 60(4) + 95 = -16(16) + 240 + 95 = -256 + 335 = 79
g(1) = 20 + 38.7(1) = 20 + 38.7 = 58.7
g(2) = 20 + 38.7(2) = 20 + 77.4 = 97.4
g(3) = 20 + 38.7(3) = 20 + 116.1 = 136.1
g(4) = 20 + 38.7(4) = 20 + 154.8 = 174.8
Between 2 and 3 seconds.
The range of the 1st object is 151 to 131.
The range of the 2nd object is 97.4 to 136.1
h(t) = g(t) ⇒ 131 = 131
<span>It means that the point where the 2 objects are equal is the point where the 1st object is falling down while the 2nd object is still going up. </span>
Multiply the first equation by 3
21x+15y=-6
Add this to the second equation
21x+15y=-6
-21x-15y=6
0+0=0
True
Final answer: Infinitely Many Solutions (they are coinciding lines)
Square part of perimeter = 40.
Half circle = 25.135.
Together 65.135 is perimeter.
Area of square: 192
Are of half circle: 100.53.
Together 292.53
Rounded =292.48 I guess, its the most logical option since I don't see it and the only one that fits perimeter answer.
So its the 3rd question I believe, you may want to double check.
