Ludmilka [50]

$h(t)=-4.9t^{2}+34.3t+1
\\h'(t)=(-4.9t^{2}+34.3t+1)'=-9.8t+34.3
\\h'(t)=0
\\-9.8t+34.3=0
\\
\\t= \frac{34.3}{9.8} =3.5
\\
\\h_{max}=h(3.5)=-4.9\times3.5^{2}+34.3\times3.5+1=61.025$

The ball reaches its maximum height after 3.5 seconds, and the maximum height is 61.025 meters.

(SAT Prep) How many distinct triangles are for which the lengths of the sides are 5,9 and n, where n is an integer and 10

Nana76 [90]

The reason why is because the sum of two sides is always larger than the value of the third side.

I hope that this helps.
