Answer:
Yes, Chris will score
Step-by-step explanation:
Given the function :
F(x) = - 0.05(x - 16)² + 11
Distance from goal = 25
Height of goal = 8
Scoring condition, if ball isn't blocked :
If the ball travels a distance of 25 feets towards goal and elevation of ball isn't greater than 8 feets, then Chris will score ;
Function which models ball height with respect to distance, x
Put x = 25 in the equation and se if f(x) < 8 feets
F(25) = - 0.05(25 - 16)² + 11
F(25) = - 0.05(9)² + 11
F(25) = - 0.05 * 81 + 11
F(25) = - 4.05 + 11
F(25) = 6.95 feets
Hence, Chris would score if ball isn't vlaocjed by DeShawn because the height of ball is lower than the height of the goal.

Answer:
y/x = -3/7
Step-by-step explanation:
Write the given relationship and solve for y/x.
(x +y)/(x -y) = 2/5
5(x +y) = 2(x -y) . . . . . multiply by 5(x-y)
5x +5y = 2x -2y . . . . . eliminate parentheses
7y = -3x . . . . . . . . . . . add 2y-5x
y/x = -3/7 . . . . . . . . divide by 7x
Answer:
x=0
Step-by-step explanation:
10(x-2)=-20
10x-20=-20
add 20 on both sides.
10x=0
10 times 0 =0
x=0
