Answer:
x=82
Step-by-step explanation:
53+45=98
180-98=82
Answer:
1260.04
Step-by-step explanation:
The formula for compound interest is:
A = P(1+
where A is the final amount, P is the initial principal balance, r is the interest rate, n is the number of times interest applied per time period and t is the number of time periods elapsed. Since the deposit was compounded annually, just like the interest, we can omit the n in the equation.
Applying the formula to question:
800(1+
= 1260.04 (rounded off to nearest cent since it's money)
Responder:
$ 11,137
Explicación paso a paso:
Como no se nos dice qué encontrar, también podemos encontrar el beneficio obtenido por la venta de 351 unidades de radio.
Dado
Función de costo C (x) = 43x + 1850
Función de ingresos R (x) = 80x
Obtener la función de ganancias
P (x) = R (x) - C (x)
P (x) = 80x - (43x + 1850)
P (x) = 80x - 43x - 1850
P (x) = 37x - 1850
Si se fabrican 351 radios, la ganancia obtenida se calculará como se muestra a continuación:
P (351) = 37 (351) - 1850
P (351) = 12,987-1850
P (351) = 11,137
<em>Por lo tanto, la ganancia obtenida de las ventas de 351 radios es de $ 11,137</em>
The solutions are C = 2 and C = -2
We can find this by solving for C.
C^2 - 4 = 0 ----> add 4 to both sides
C^2 = 4 ----> Take the square root of both sides
C = 2
However, since we used the square root function, we have to include a negative form of the answer as well as the positive one we found.
