un futbolista patea una pelota que se encuentra en el parto con un ángulo 30° ( medido desde la horizontal) posición si le altura del arco de 2 metros (medida entre el pasto y el travesaño) y el jugador patea directamente en dirección al arco ¿a qué velocidad debe patear la pelota para hacer el gol ? ¿cuanto tiempo se demora la pelota en llegar al arco?​

answer:      

step-by-step explanation:

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.

if e is the midpoint of bd, then bd is 14.
