There are 10 possible ways to select a president from the club, because their are 10 available members to choose from.
After a president is chosen, their are 9 possible ways to select a vice president, because one of the members will already have the position of president, so they can't be vice president (10-1=9)
Now we just multiply to possibilities of presidents by the possibilities of vice-presidents.
president*vicepresident=
10*9=90
Answer= D. 90
The answer to thus problem is 269. 7
G - 99 = the amount of gumballs Seema has
Answer: the maximum is (-2,5 )and the equation for the axis of symmetry is x = -2
Explanation if you want:
for the min and max: when a quadratic has a maximum point, that is the largest point that it will ever be at. When it has a minimum, that is the smallest.
- the +5 tells us that we have an upward movement of 5. The +2 means we actually move to the point -2. bc: (x+2)=0 = -2
- so, from our initial function, those are the changes.
for the axis of symmetry: basically, this is the line that splits the graph into two equal parts.
- it is the line that goes through the vertex (which we already know is (-2,5).
there u go
