Two ships left a port at the same time. one ship traveled at a speed of 19 miles per hour at a heading of 320°. the other ship traveled at a speed of 28 miles per hour at a heading of 197°. find the distance between the two ships after 10 hours of travel. (round your answer to the nearest mile.) this is what i've got so far, but it didn't come out right according to my homework. thoughts? (280)^2 + (190)^2 - 2(280)(190)cos(83) = 101,533.1019 (take the square root of this number) = 318.6

Write each expression in exponential form and find its value. 3 x 3 x 3

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
