The temperature of a person during a certain illness is given by the following equation, where \( T \) is the temperature \( \left({ }^{\circ} \mathrm{F}\right) \) at time \( t \), in days. Find the relative extreme points and sketch a graph of the function. \( T(t)=-03 t^{2}+24 t+983,0 \leq t \leq 8 \)

\( 1,3,5 + 1,25 \)

Na equação: \( 3 x^{2}+2 x+c^{2}=0 \), sendo o coeficiente \( c \) um número negativo, o valor de \( \underline{c} \) para que o produto entre as raízes dessa equação seja 48 é: \( \begin{array}{lllll}\text { a) }-11 & \text { b) }-8 & \text { c) }-9 & \text { d) }-14 & \text { e) }-12\end{array} \)

The length of a rectangle is 5 meters less than twice the width. If the area of the rectangle is 493 square m The width is \( \square \) meters. The length is \( \square \) meters.

\( 1000\int _{}^{}\frac{x^{3}}{\sqrt {x^{2}+100}} d x \)
