En una clase hay 25 estudiantes. Elena dice que \( \frac{3}{5} \) partes del total de estudiantes son chicas y Javier dice que hay 10 chicos ¿Pueden tener razón los dos a la vez?

\( \frac{\times }{3}=\frac{6}{8} \)

\( a: 27=4: 3 \) what is the value of a ? \( \begin{array}{lll}\frac{4}{9} & \text { (b) } 36 & \text { (c) } \frac{81}{4}\end{array} \)

The population of a rural city follows the exponential growth model \( P(t)=3400 e^{0.039 t} \) where \( t \) is the number of years after 1994. a) What was the population of this city in 1994 ? b) What is the relative growth rate as a percent? c) Use this model to approximate the population in 2040 . a) The population in the year 1994 was b) The relative growth rate is \( \square \% \). c) The projected population for the year 2040 is (Round to the nearest whole number as needed.)

Suppose that the functions \( q \) and \( r \) are defined as follows. \[ \begin{array}{l}q(x)=-2 x+1 \\ r(x)=2 x^{2}-1 \\ (r \circ q)(-3)=\square \\ (q \circ r)(-3)=\square\end{array} \] Find the following.
