On the football team, two out of every seven players are seniors. If the team has 84 players, how many of the players are seniors.

the number of players being seniors is 24

Step-by-step explanation:

For every 7 players at least 2 were seniors so you can make it into a ratio 2:7. When you divide 84 by 7 you get 12 then multiply 12 with 2 and you get 24.

have good day ( ^﹏^)

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
