kirill115 [55]
Check the picture below.

\bf \textit{ vertex of a vertical parabola, using coefficients}\\\\
\begin{array}{lccclll}
h(t) = &{{ -16}}t^2&{{ +96}}t&{{ +2560}}\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad 
\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad  {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)

so.. the maximum point is at   \bf {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}~~~ft

and it happened after   \bf -\cfrac{{{ b}}}{2{{ a}}}~~~seconds

--------------------------------------------------------------------------

now, when the rocket reaches the ground, as you saw on the picture, y = 0, thus

\bf h(t)=-16t^2+96t+2560\implies 0=-16t^2+96t+2560
\\\\\\
0=-16(t^2-6t-160)\implies 0=t^2-6t-160
\\\\\\
0=(t-16)(t+10)\implies t=
\begin{cases}
\boxed{16}\\
-10
\end{cases}

"t" is an amount in seconds, for this specific phenomena, it cannot be negative, so -10 is not a feasible value.

What is the number in scientific notation? ​0.0765
devlian [24]

Answer:

7.65 * 10^{-2} is scientific notation of 0.0765

Step-by-step explanation:

For scientific notation , follow the following notation:

a * 10^{b} -------->(equation 1)

Let,  a^{'} =  0.0765

In standard form

 a =  7.65

As decimal point move 2 places from left to right, therefore

b = -2

Put the value of 'a' and 'b' in (equation 1)

7.65 * 10^{-2} is scientific notation of 0.0765
