What is the least common multiple (LCM) of 4 and 6?

7. \( -8-(-6) \)

Convert this fraction into decimal form. Round any repeating decimals to two digits (hundredths).

The cost, in thousands of dollars, of airing \( x \) television commercials during a sports event is given by \[ C(x)=150+2,400 x-0.08 x^{2} \] (a) Find the marginal cost function \( C^{\prime}(x) \). \( C^{\prime}(x)=2400-0.16 x \) (b) Use the marginal cost to approximate the cost to air the 5 th commercial. Convert your answer to dollars. The cost to air the 5 th commercial is approximately 2399360 (c) What is the exact cost to air the 5 th commercial? Convert your answer to dollars. The exact cost to air the 5 th commercial is

Use Newton's method to find the two real solutions of the equation \( x^{4}-3 x^{3}-3 x^{2}-x+2=0 \). Compute successive approximations to find the solutions to five decimal places. \( x=\square \) (Use a comma to separate answers as needed. Type an integer or decimal rounded to five decimal places as needed.)

95. \( (\sqrt{2}, 3 \sqrt{5}),(\sqrt{2},-2 \sqrt{5}) \)
