first make two triangles using M , so there iwll be 90-45-45, and 30-60-90 then use the side rules of those special triangles
total mass = mass of a bag of candy + mass of a chocolate bar
total mass = 80g +110g = 190g
<u>Part A</u>
<u />
<u>Part B</u>
The vertex of the graph will be a maximum because the leading coefficient is negative.
The x coordinate of the vertex is
.
When x=15/8,
.
So, the vertex has coordinates 
<u>Part C</u>
Plot the two x-intercepts and the vertex and then draw a curve in the shape of a parabola passing through them.
The graph is in the attached image.
