Calcula el monto total acumulado al cabo de 18 meses si en cada caso el capital inicial fue de \( \$ 12000000 \). a. Tasa de interés simple del \( 8 \% \) anual b. Tasa de interés simple del \( 0,9 \% \) mensual c. Tasa de interés simple del \( 0,01 \% \) diario

\[ C=\frac{\text { Work }}{m_{\text {water }} \Delta T} \] Use this equation to calculate the specific heat of the water for each trail in part 2. Take note that if the beaker contains 296 ml of water, it will also be 296 g of water. Mass of water (mvater):

For example, consider the following balanc \[ \mathrm{N}_{2}(\mathrm{~g})+3 \mathrm{H}_{2} \] From this equation, there are several possil mole ratios are the following: \[ \frac{3 \text { moles } \mathrm{H}_{2}}{1 \text { mole } \mathrm{N}_{2}} \] Which is a possible mole-mole ratio for the \[ 4 \mathrm{Fe}(\mathrm{s})+3 \mathrm{O}_{2} \]

Assume that a sample is used to estimate a population mean \( \mu \). Find the \( 99.9 \% \) confidence interval for sample of size 42 with a mean of 43.8 and a standard deviation of 16.1 . Enter your answer as an open- interval (i.e., parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place). \( 99.9 \% \) c.I. \( = \)

Joe is going to invest to help with a down payment on a home. How much would he have to invest to have \( \$ 54,300 \) after 7 years, assuming an interest rate of \( 1.79 \% \) compounded monthly? Do not round any intermediate computations, and round your final answer to the nearest dollar. If necessary, refer to the list of financial formulas.
