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

<h3>
1. Compare Functions B and L by determining which one has the greater rate of change.</h3>
The rate of change is expressed as the ratio between a change in one variable relative to a corresponding change in another. On the other hand, a linear function is given as the form:
And 
is the rate of change we are looking for. For Function B we have a Table and the slope can be found by choosing two points, therefore:
As you can see 
has a rate of change of 6 while the function of the table has a rate of change of 3.
<em> In conclusion,</em> <em>has the greater rate of change</em>
<h3>
2. which one has a greater y-intercept?</h3>
We need to get the equation that rules the points given on the table. Two-Point Form of the Equation of a Line is:
As you can see has a y-intercept of 
while the function of the table has a y-intercept of 
<em> In conclusion,</em> <em>also has the greater y-intercept</em>
Answer:
2
Step-by-step explanation:
20-7x=6x-6
20+6=6x+7x
26=13x
x=2
A = pi times radius squared (radius is half the 16 inch diameter so 8 inches)
A = 3.14 x r^2
A = 3.14 x 8^2
A - 200.96 sq inches
