Person = 1 head and 2 legs
horse = 1 head and 4 legs
p +h = 74
p = 74-h
2p +4h = 196
2(74-h) +4h = 196
148-2h +4h = 196
148 +2h = 196
2h = 48
h = 48/2 = 24
24 horses
50 people
answer is B
First off, a million dollars in pennies is 100,000,000. Let's see:
1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 + 512 + 1024 + 2048 + 4096 + 8192 + 16384 (HALFWAY POINT) + 32768 + 65536 + 131072 + 262144 + 524288 + 1,048,576 + 2,097,152 + 4,194,304 + 8,388,608 + 16,777,216 + 33,554,432 + 67,108,864 + 134,217,728. This is where I'll stop, because now the penny scenario is more money, but there were still some days left.

We can use quadratic formula
a=3, b= -1, c=4
we are given
(a)
we can plug t=0
so, the height above the ground when the object is launched is 60 meter......Answer
(b)
we can set s(t)=0
and then we can solve for t
we can use quadratic formula
we get
..........Answer
(c)
we can find vertex
t=2.040816
now, we can plug it back
so, the maximum height is 80.408meter.........Answer
