a potato is fired from a spud gun at a height of 3M and an initial velocity of 25 meters per second, write the equation of this
gizmo_the_mogwai [7]
Check the picture below, the height there uses feet, but nevermind that, we can simply let it be meters, like in this case.

\bf ~~~~~~\textit{initial velocity}
\\\\
\begin{array}{llll}
~~~~~~\textit{in meters}
\\\\
h(t) = -4.9t^2+v_ot+h_o
\end{array} 
\quad 
\begin{cases}
v_o=\stackrel{25}{\textit{initial velocity of the object}}\\\\
h_o=\stackrel{3}{\textit{initial height of the object}}\\\\
h=\stackrel{}{\textit{height of the object at "t" seconds}}
\end{cases}
\\\\\\
h(t)=-4.9t^2+25t+3

how hight does it go?  well, that'd be the y-coordinate of the vertex.

how long does it take?  well, that'd be the x-coordinate of the vertex.

\bf \textit{vertex of a vertical parabola, using coefficients}
\\\\
\begin{array}{lcccl}
h(t) = & -4.9t^2& +25t& +3\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}
\qquad 
\left(-\cfrac{ b}{2 a}\quad ,\quad   c-\cfrac{ b^2}{4 a}\right)
\\\\\\
\left(-\cfrac{25}{2(-4.9)}~~,~~3-\cfrac{25^2}{4(-4.9)}  \right)\implies \left( \cfrac{25}{9.8}~~,~~3-\cfrac{625}{-19.6} \right)
\\\\\\
\left( \cfrac{25}{9.8}~~,~~3+\cfrac{625}{19.6} \right)\implies \left( \cfrac{25}{9.8}~~,~~\cfrac{3419}{98} \right)

This function can be used to determine the number of bacteria in a culture h hours after the culture was started.
dimulka [17.4K]

Answer:

The statement means that after 2 hours, there are 90 bacteria in the culture.

Step-by-step explanation:

The number of bacteria after x hours is given by the function states in the exercise. We have that f(x) will be the number of bacteria after x hours.

Which statement best describes the meaning of the equation f(2) = 90 ?

The statement means that after 2 hours, there are 90 bacteria in the culture.

Explain how to round 14 5/6 to the nearest whole number, using the number line as a tool. Use complete sentences in your answer.
ehidna [41]

Answer:

15

Step-by-step explanation:

From the given information:

The distance of one consecutive number on a number line to the other is usually 1.0.

To round up 14 5/6 to the nearest whole number, we need to take a proper look at the improper fraction 5/6.

We know that:

6/6 = 1

3/6 = 0.5

5/6 is more than 3/6 and the decimal form is approximately 0.8

Thus 14+0.8 = 14.8, and that is approximately 15 on a number line.
