If 2 gallons of oil are used a day, than he will need 60 gallons of oil, because 30x2=60. For 60 gallons of oil, you would have to have 12 drums because 60÷5=12. Because there is already 8 drums of oil, there would already be 40 gallons because 8x5=40. If the owner already had 40 gallons of oil, they would only have to get 20 more gallons because 60-40=20. That would be 4 drums because 20÷5=4. The owner would have to order 4 more drums of oil.

Create the equation of a quadratic function with a vertex of (5,6) and a y-intercept of -69
Elena L [17]
If the y-intercept is at -69, meaning the point is (0, -69), thus x = 0, y = -69

\bf ~~~~~~\textit{parabola vertex form}&#10;\\\\&#10;\begin{array}{llll}&#10;\boxed{y=a(x- h)^2+ k}\\\\&#10;x=a(y- k)^2+ h&#10;\end{array}&#10;\qquad\qquad&#10;vertex~~(\stackrel{}{ h},\stackrel{}{ k})\\\\&#10;-------------------------------\\\\&#10;vertex~(5,6)\quad &#10;\begin{cases}&#10;x=5\\&#10;y=6&#10;\end{cases}\implies y=a(x-5)^2+6&#10;\\\\\\&#10;\textit{we also know that }&#10;\begin{cases}&#10;x=0\\&#10;y=-69&#10;\end{cases}\implies -69=a(0-5)^2+6&#10;\\\\\\&#10;-75=25a\implies \cfrac{-75}{25}=a\implies a=-3&#10;\\\\\\&#10;therefore\qquad \boxed{y=-3(x-5)^2+6}

cricket20 [7]

Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.So the equation to solve this would be simply 90 multiply 2 which gives you the answer of 180 degree in this situation.
