THE ANSWER IS B , because you find find the radius that is 9 and then you you multiply 9 times 9 and it would give you 81 and then you multiply 3.14 times 81 . And it would give you 254.54 and I know I am right because I got right I had the same problem

To celebrate a diners anniversary, the owners have made a 40 foot long sandwich. The sandwich is cut into three unequal pieces.

Ivahew [28]

Let x be he length of middle piece.
3x = length of longer piece.
x-5 = length of shortest piece.

x + 3x + x-5 = 40
5x - 5 = 40
5x = 45
x = 45/5
x = 9. ( Size of middle piece )

Given that the longer piece is 3 times the size of middle piece,

Longest piece = 3 x 9 = 27.

Size of longest piece = 27 feet
Size of middle piece = 9 feet
Size of smaller piece = 40 - (27+9)
= 40 - 36
= 4 feet.
Thank you.

Una compañía sabe que si produce "x" unidades mensuales su utilidad "u" se podría calcular con la expresión:

belka [17]

Answer:

Δf(u) /Δx = 92,8 ( razón de cambio promedio)

Step-by-step explanation:

La expresión de la utilidad de la empresa u(x) en función de la cantidad de unidades producidas "x" es:

u(x) = 0,04*x² + 44*x -4000

Entonces la razón de cambio promedio en un intervalo (a ; b) en este caso ( 620 ; 600 ) viene dada por la expresión:

Δf(x)/ Δx = [ f(b) - f(a) ]/( b - a )

en donde f(b) y f(a) se obtienen por sustitución de los valores a y b es decir 600 y 620 respectivamente en la función f(x) = u(x) entonces

Δf(u) /Δx = [ u(b) - u(a) ]/( b -a ) (1)

u(b) = 0,04*(620)² + 44*(620) - 4000

u(b) = 15376 + 27280 -4000

u(b) = 2656 unidades

u(a) = 0,04* (600)² + 44* 600 - 4000

u(a) = 14400 + 26400 - 4000

u(a) = 800

Sustituyendo esos valores en la ecuación 1

Δf(u) /Δx = 2656 - 800 / 620 - 600

Δf(u) /Δx = 92,8
