<span>(t) = 0 gives
</span><span>-24t + 60 = 0
</span><span>t = 2.5
</span><span>For this t, the second derivative s"(t) = -24 is negative. And so, s(t) is maximum for t = 2.5.
</span><span>Maximum height is S = -12(2.5)^2 + 60(2.5) +8 = 233ft</span>
Answer:
X=5
Step-by-step explanation:
X=1/3 or x=-2
explanation:
Find factors of 3 and 2 which subtract to make 5.
We should realise that (3x2) - 1 = 5.
Find the cross products and subtract to get 5. Add in the signs. One of the factors must be 0.
Answer:
Step-by-step explanation:
set the two equations equal to each other then solve for n
6n + 3 = 4n + 11
2n = 8
n = 4
plug n in for both equations
6(4) + 3
24 + 3 = 27
4(4) + 11
16 + 11 = 27
27 + 27 = 54
the distance is 54
