Answer:
<em>La masa del paracaidista es 7.14 Kg</em>
Step-by-step explanation:
<u>Peso y Masa</u>
La masa de un objeto es una medida de la cantidad de material que el objeto posee. Sus unidades más comunes son el Kg, gr, lb, Ton.
El peso de un objeto de masa m es la fuerza con la cual la Tierra atrae al objeto a través de la aceleración de gravedad g. Sus unidades son iguales a las de cualquier fuerza, es decir, Nw, Kgf, Dina. Su fórmula es:
P=m.g
Si tenemos el peso P=70 N, podemos calcular la masa, despejándola de la fórmula:
Sustituyendo los valores:
La masa del paracaidista es 7.14 Kg
I am not in 8th grade but it might be the 2nd one
<u><em>v=-6 is the right answer. </em></u> First you had to subtract by 7 from both sides of equation, and it gave us, . And then simplify, and it gave us, . You can also add by 8v from both sides of equation, and it gave us, . Next simplify, and it gave us, . Then you divide by 2 from both sides of equation, and it gave us, . And finally simplify, and it gave us the answer is <u><em>v=-6 is the right answer.</em></u> Hope this helps!

Answer:
Step-by-step explanation:
Given that a company fixed costs are 400 dollars
and variable cost = per unit and x the no of units produced
Selling price = per unit
a) Break even units
At break even units selling price = variable cost
Break even units = 76
b) Revenue = Sales - total costs
=
Use derivative test to get max revenue
R'(x) =
R"(X) <0
So maximum when I derivative =0 or when
x=38
c) price when x =38 is
