**A rock dropped from a 100 foot tower.

mars1129 [50]

Answer:

2.83 s

Step-by-step explanation:

We are given that

$h(t)=-16t^2+10t+100$

When a rock reached the ground then h(t)=0

$-16t^2+10t+100=0$

$16t^2-10t-100=0$

Using quadratic formula

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$t=\frac{10\pm\sqrt{(-10)^2-4\times 16\times (-100)}}{2(16)}$

$t=\frac{10\pm\sqrt{100+6400}}{32}$

$t=\frac{10+\sqrt{6500}}{32}=2.83$

$t=\frac{10-\sqrt{6500}}{32}=-2.2$

Time cannot be negative .Therefore, negative value of t can not be possible.

Hence, the rock takes 2.83 sec to reach the ground.

Someone help me please, i will give brainliest this is due soooooon!1111

Darya [45]

Answer:

216

Step-by-step explanation:

I'm sure there is a simpler way to do this but this is how I did it.

First divide 18 by 6 because it triples every 6 hours.

18/6=3

This means it will triple three times

Then triple the value three times

#1. 8x3=24

#2. 24x3=72

#3. 72x3=216

In 18 hours the virus will infect 216 people.
