X=33j
or if ya wanna be fancy and have a double answer:
33j=x
Answer:
1) Factor form : 
2) 8 second after launch.
Step-by-step explanation:
The height of the ball (in meters above the ground) t seconds after launch is modeled by
To find the time when ball hit the ground, we need to find the factor form of the given function.
When ball hi the ground, then height of the ball from the ground is 0.
Using zero product property, we get
Ball hit the ground at t=0 and t=8. It means ball hit the ground in starting and 8 second after launch.
Answer:
x + x + 2
Step-by-step explanation:
cuz if its consecutive odd then its every 2 numbers so if x = 3 then you add two to x
Resposta: 30
Explicação passo a passo:
Dado o seguinte:
Preço para atingir a meta = $ 20
Penalidade por falta de alvo = $ 10
Se 80 tiros forem disparados e os participantes receberem $ 100.
Número de vezes que o participante atinge o alvo.
Deixe o número de erros = m
Deixe o número de acertos = h
h + m = 80 - - - - (1)
20h - 10m = 100 - - - (2)
h = 80 - m
Substitua h = 80 - m em (2)
20 (80 - m) - 10m = 100
1600 - 20m - 10m = 100
-30m = 100 - 1600
-30m = - 1500
m = 50
De (h = 80 - m)
h = 80 - 50
h = 30
Número de acertos = 30
O participante acerta o alvo 30 vezes
