H= -16t^2+16t+192 When will the ball hit the ground?

Nadusha1986 [10]

-16t^2+16t+192= 0 (when the ball hits the ground, h will be zero)

Use the quadratic formula to solve the equation (If you don't know how to solve quadratic equations, just ping me dude and I'll try my best to help you)

We get x=-3 and 4

Now since time can't be negative, therefore the answer is after 4 seconds

50 POINTS AND MARK BRAINLIEST

givi [52]

Step-by-step explanation:

a) Using the distance formula,

$RS=\sqrt{(2-4)^{2}+(3-4)^{2}}=\sqrt{4+1}=\boxed{\sqrt{5}}\\ST=\sqrt{(4-5)^{2}+(4-0)^{2}}=\sqrt{1+16}=\boxed{\sqrt{17}}\\RT=\sqrt{(2-5)^{2}+(3-0)^{2}}=\sqrt{9+9}=\boxed{3\sqrt{2}}$

b) Using the slope formula,

$m_{\overline{RS}}=\frac{4-3}{4-2}=\boxed{\frac{1}{2}}\\m_{\overline{ST}}=\frac{0-4}{5-4}=\boxed{-4}\\m_{\overline{RT}}=\frac{0-3}{5-2}=\boxed{-1}$

c) The triangle is <em>scalene</em> because each of the sides is of a different length.
