For this case we have the following function:
<span>w (x) = - 5 (x-8) (x + 4)
</span><span>Rewriting we have:
</span><span>w (x) = - 5 (x ^ 2 + 4x - 8x - 32)
</span><span>w (x) = - 5x ^ 2 - 20x + 40x + 160
</span><span>w (x) = - 5x ^ 2 + 20x + 160
</span><span>Then, deriving we have:
</span><span>w '(x) = - 10x + 20
</span><span>We equal zero and clear x:
</span><span>0 = -10x + 20
</span><span>10x = 20
</span><span>x = 20/10
</span><span>x = 2 seconds
</span><span>Substituting values:
</span><span>w (2) = - 5 (2-8) (2 + 4)
</span><span>w (2) = - 5 (-6) (6)
</span><span>w (2) = 180 meters
</span>Answer:
The maximum height that the stone will reach is:
w (2) = 180 meters
Answer:
y=3/2x+-1
Step-by-step explanation:
the formula is y=mx+b
y is the total
m is the slope
x is what you're multiplying the slope by
b is the y intercept
Answer:
100
Step-by-step explanation:
because it is the nearist hundred and the closest hundred to 3 has to be 100
Answer:
yes
Step-by-step explanation:
i dont know
9x + 27
-2y + 20
4x - 24
30x + 12xy
15x + 2 (?)
