Question
Use Newton's method to approximate the solution to the equation \( \frac{5}{x-10}=x+6 \). Use \( x_{0}=-5 \) as your starting value
to find the approximation \( x_{2} \) rounded to the nearest thousandth.
Sorry, that's incorrect. Try again?
\[ x_{2} \approx \square \]
Q:
506 Un trapezio isoscele \( A B C D \) ha gli angoli adiacenti
alla base maggiore \( A B \) di \( 45^{\circ} \). La somma della base mag-
giore e del doppio della minore è 21 cm , mentre la som-
ma della base minore e dell'altezza è 8 cm . Determina
l'area del trapezio.

\( \begin{array}{llll}\text { A. } 47 & \text { B. } 48 & \text { C. } 48 & \text { D. } 94\end{array} \)
Q:
A set of exam scores is normally distributed with a mean \( =74 \) and standard deviation \( =8 \).
\( 95 \% \) of the data values lie between 58
\( \% \) of the exam scores are between 66 and 74 .
\( \% \) of the exam scores are between 74 and 90 .
\% of the exam scores are greater than or equal to 66 .
Q:
Approximate the area under the graph of \( f(x) \) and above the \( x \)-axis using \( n \) rectangles.
\( f(x)=2 x+3 \) from \( x=0 \) to \( x=2 ; n=4 \); use right endpoints

Q:
In a normal distribution, a data value located 1.4 standard deviations below the mean has Standard Score:
\( \mathrm{z}=-1.4 \)
In a normal distribution, a data value located 2.3 standard deviations above the mean has Standard Score:
\( \mathrm{z}=2.3 \)
In a normal distribution, the mean has Standard Score: \( \mathrm{z}=\square \)
Q:
A certain tranquilizer decays exponentially in
the bloodstream and has a half-life of 22
hours. How long with it take for the drug
to decuy to \( 82 \% \) of the original dose?
a) step 1 : Find \( K \) (Round to four decimalpleas)
b) step 2 : Use \( k \) to determine how longlinhours)
it will take for the drug to decay to \( 82 \% \) of
the original dose. (Round to one decinalplace)
