A sample of hexane (C6H14) has a mass of 0. 580 g. The sample is burned in a bomb calorimeter that has a mass of 1. 900 kg and a specific heat of 3. 21 J/giK. What amount of heat is produced during the combustion of hexane if the temperature of the calorimeter increases by 4. 542 K? Use q equals m C subscript p Delta T. 8. 46 kJ 16. 1 kJ 27. 7 kJ 47. 8 kJ.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
