1 3/5 x 2 3/4
= 8/5 x 11/4
= 22/5
= 4 2/5 (4 and 2/5)
N=number
n+12 is the expression
A. When the key reaches the ground, h = 0.
0 = -16t^2 + 64
16t^2 = 64
t^2 = 4
t = 2 seconds.
B. The reasonable domain of the function is [0, 2], since the function does not hold when the key reaches the ground. The range of the function is [0, 64] which corresponds to the domain.
<span>zebra fish a then tetras fish (11 – a)
2.2a + 1.85(11 – a) = 22.80
2.2a + 20.35 – 1.85a = 22.80
0.35a = 2.45
a = 7 zebra and 11 – 7 = 4 neon fish
