Since the force 235 N is at an angle, you want it to be parallell with the ground. To do that you do the cosine of the angle multiplied by the force. So 235*cos34.8 = 192.97 N Using F=ma 192.97=19a so a= 10.1563 m/s^2

C(5) would be the cost to make 5 sailboats, so substitute 5 for 'x' (2 * 5) + 20 10 + 20 = 30; since the question says the cost is in thousands of dollars, then C(5) is how much it costs the company to make 5 sailboats, which is \$30,000 or \$6,000 / sailboat.

To find the product of two fractions, you simply multiply across top & bottom. But first, you can see that 12 and 15 have a common factor of 3. So, (11 / 15) * (12 / 7) then becomes: (11 / 5) * (4 * 7) Multiplying straight across, you get: (11 * 4) / (5 * 7) = 44 / 35
