(a) Explanation Given: The function: f ( x ) = 1.2 ln ( x ) + 15.7 The graph is as follows: Calculation: Consider the above graph. Here, f ( x ) determines the US-GDP toward the health care after x years of 2006 . For the year 2009 : x = 2009 − 2006 = 3 Put the values in the function as follows: f ( x ) = 1 (b) To determine To calculate: The year when US-GDP given by f ( x ) = 1.2 ln ( x ) + 15.7 reaches 18.5 % . The graph is as follows:

By 2019, nearly $1 out of every $5 spent in the U.S. economy is projected to go for health care. The bar graph shows the percentage of the U.S. gross domestic product (GDP) going toward health care from 2007 through 2014, with a projection for 2019. The data can be modeled by the function f (x) = 1.2 ln x + 15.7, where f (x) is the percentage of the U.S. gross domestic product going toward health care x years after 2006. Solve, According to the model, when will 18.5% of the U.S. gross domestic product go toward health care? Round to the nearest year.

Sunlight is absorbed in water, and as a result the light intensity in oceans, lakes, and ponds decreases exponentially with depth. The percentage of visible light -kx P (in decimal form) at a depth of x meters is given by P=e, where k is a constant related to the clarity and other physical properties of the water. The graph shows models for the open ocean, Lake Tahoe, and Lake Erie for data taken under similar conditions. Percent 0.8- 0.2- Percent of Surface Light vs. Depth -0.0491 x Ocean: P = e Tahoe: P = e -0.0799 x Depth (m) Erie: P = e -0.1980 x The euphotic depth for the open ocean is The euphotic depth is the depth at which light intensity falls to 1% of the value at the surface. This depth is of interest to scientists because no appreciable photosynthesis takes place. Find the euphotic depth for the open ocean. Round to the nearest tenth of a meter. meters. X
