Answer:
k = 10.39
Step-by-step explanation:
tangent 30 = opposite side / adjacent side, opposite side = 9, adjacent side = k + 3sqrt3.
tan 30 = 9/(k + 3sqrt3)
0.5774 = 9/(k + 3sqrt3)
k + 3sqrt3 = 15.5885
k = 15.5885 - 3sqrt3
k = 10.392
I think it might be 12.92. just divide 193.75 by 15. you get <span>12.916... round the cost to the nearest cent and you get 12.92. yay!!</span>
I hate those scams that post links. They’re not true. Don’t fall for them.
Answer:
openup 1 em We want to find the points on the curve y=2x^3-3x^2-12x+20y where the tangent line is parallel to the xx-axis, which means that the slope=0
