18. Math and Science There are 2.000 pounds in a ton. How can you write 2.000 with an exponent? Scientifle notation is writhen as one digit timn power of ter.

In the cost function below, \( C(x) \) is the cost of producing \( x \) items. Find the average cost per item when the required number of items is produced. \( C(x)=4.5 x+9,300 \) \( \begin{array}{lll}\text { a. } 200 \text { items } & \text { b. } 2000 \text { items } & \text { c. } 5000 \text { items }\end{array} \)

fica en la aplicación de Geogebra las slguientes funciones, escribe la tabla de valores que armo/a, realia la ica y clasifica la función en lineal o atín \[ f(x)=-2 x \quad f(x)=5 x-2 \]

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

Evaluate the expression without using a calculator. \( \log _{14} \frac{1}{\sqrt{14}} \) \( \log _{14} \frac{1}{\sqrt{14}}=\square \)

Evaluate the expression without using a calculator. \( \log 1000 \) \( \log 1000=\square \)
