12. Si R(x)=-5x2+x-2 y S(x)=-x - 3x, se ¿cuál es el resultado de R(x) + S(x) ?

lesya692 [45]

Answer:

El resultado eres: $R(x) + S(x) = -6x^2 - 2x - 2$

Step-by-step explanation:

Se dan las siguientes funciones

$R(x) = -5x^2 + x - 2$

$S(x) = -x^2 - 3x$

Cuál es el resultado de R(x) + S(x) ?

Se soman los fatores en comun. Entonces:

$R(x) + S(x) = -5x^2 + x - 2 + (-x^2 - 3x) = -5x^2 + x - 2 - x^2 - 3x = -5x^2 - x^2 + x - 3x - 2 = -6x^2 - 2x - 2$

El resultado eres: $R(x) + S(x) = -6x^2 - 2x - 2$

An ice cream cone has a radius of 4 inches and a height of 9 inches. What is the exact value of the volume of the ice cream cone

Nata [24]

πr^2h/3
this is a formula if it is a right angle cone
π(4)^2 (9)/3
exponent, 4^2 then times by π
after times by (9/3)=
≈150.8

I think, double check and see if right
