\(22 \) The area of a piece of land is \( 4,951,000 \) square meters. How is this number of square meters Written in scientific notation?
F \( 4.951 \times 10 ^ { 6 } \)
G \( 4.951 \times 10 ^ { - 6 } \)
H \( 4,951 \times 10 ^ { 3 } \)
J \( 4,951 \times 10 ^ { - 3 }\)
F
A linear function that models data is described below. Find the slope of the model. Then describe what this means in terms of the rate of change of the dependent variable per unit change in the independent variable. The linear function \( f ( x ) = - 0.41 x + 28.6 \) models the percentage of adults in a country who smoked cigarettes, \( f ( x ) \) , \( x \) years after \( 1997 \) .
The slope is \( \square \) . (Type an integer or a decimal.)
Use the quadratic formula or completing the square to determine the greater solution to
\( x ^ { 2 } + 4 x + 2 = 0 \) . Round your answer to the nearest hundredth. Record your answer and fill in the bubbles on your answer document.
