H=7 + 29t-16t^2 find all values of t for which the balls height is 19ft
NikAS [45]
\bf \qquad \textit{initial velocity}\\\\
\begin{array}{llll}
\qquad \textit{in feet}\\\\
h(t) = -16t^2+v_ot+h_o
\end{array} 
\quad 
\begin{cases}
v_o=\textit{initial velocity of the object}\\
h_o=\textit{initial height of the object}\\
h=\textit{height of the object at "t" seconds}
\end{cases}\\\\
-------------------------------\\\\

\bf h(t)=7+29t-16t^2\qquad h(t)=19\implies 19=7+29t-16t^2
\\\\\\
16t^2-29t+12=0\impliedby \textit{now, let's use the quadratic formula}
\\\\\\
t=\cfrac{-(-29)\pm\sqrt{(-29)^2-4(16)(12)}}{2(16)}\implies t=\cfrac{29\pm\sqrt{841-768}}{32}
\\\\\\
t=\cfrac{29\pm\sqrt{73}}{32}\implies t\approx 
\begin{cases}
1.17\\
0.64
\end{cases}

so  hmm check the picture below, thus the ball hits 19 feet of height twice, once on the way up, and once on the way down, at about 0.64 seconds and at 1.17 seconds.

The dosage for a drug used to treat a male Siberian tiger that weighs 550 pounds is based on the tiger's weight in kilograms (kg
algol [13]

Answer:

227.2727 kilograms

Step-by-step explanation:

The tiger weight is 550 pounds, and we want to convert this value to kilograms, so we need to use the ratio between pounds and kilograms.

We know that 1 kilogram is equal to 2.2 pounds, so we can solve this problem using a rule of three:

1 kilogram is equal to 2.2 pounds,

X kilograms are equal to 550 pounds.

1/X = 2.2/500

X = 500/2.2 = 227.2727 kilograms

So the weight of the tiger in kilograms is 227.2727 kilograms.
