Please help
Schach [20]

Answer:

Hence, option: B is correct (11.02 seconds)

Step-by-step explanation:

Spencer hits a tennis ball past his opponent. The height of the tennis ball, in feet, is modeled by the equation h(t) = –0.075t2 + 0.6t + 2.5, where t is the time since the tennis ball was hit, measured in seconds.

Now we are asked:

How long does it take for the ball to reach the ground?

i.e. we have to find the value of t such that height is zero i.e. h(t)=0.

-0.075t2+0.6t+2.5=0

or 0.075t^2-0.6t-2.5=0

i.e. we need to find the roots of the above quadratic equation.

on solving the equation we get two roots as:

t≈ -3.02377 and t≈11.0238

As time can't be negative; hence we will consider the value of t as t≈11.0238.

Hence it takes 11.02 seconds for the ball to reach the ground.

Hence option B is correct (11.02 seconds).

SUPER URGENT Sam is eating a Big Hamburger. The first bite was 20% of the Hamburger, the second bite was 20% of what is left and
TiliK225 [7]

Answer:

hello

we can think like the hamburger is all equal to 100.

if the first bite was %20 of the hamburger, we can say there left 80. because 100×20/100 its = 20 and 100-20= 80. the problem is not this i wanna say. there was a teory similar like this problem.

a girl was going to her home. in every step she was going 2/1 of the road.. it was impossible to arrive to home.

we said 100 for all hamburger right?

it would be 0,0000000100 too..

so if we continued to dividing by %20 everytime, we never had a result of it.

maybe at least we found 0,0000000000001.

And? then we had to found 0,0000000000001's %20.

soo, the problem's answer is its not possible.

good luck(: (sry for nub eng)
