Answer:
D. 4 real roots and 0 complex roots
Step-by-step explanation:
If I assume that the function you are saying is

There should be up to "4 roots," there can't be more or less than 4 total solutions. First, we need to check how many sign changes are there in this function. There are 3 positive real roots. Now lets check for negative roots.
There are is only 1 negative real root. Since we basically have 4 real roots, and the max is 4. There should be 4 real roots and 0 complex roots.
X=6
First subtract 11 from both sides and you'll get 5x^2=180 then divide 180 by 5 which equals 36 you get x^2=36 find square root of 36 is 6

Essentially look at your formula sheets, Take notes on your assessment questions and you should be fine.
Responder:
3 / 4x + 1/2 = x
Explicación paso a paso:
Dado que:
Capacidad total = x
Volumen inicial = cierta fracción * capacidad total
Volumen adicional agregado para llenar = 1/2
Por eso,
Inicial. Volumen + volumen adicional = volumen total
De las opciones:
Un volumen inicial de 3 / 4x
Volumen adicional de 1/2
Volumen total = x
Sumar todo hace que la ecuación:
3 / 4x + 1/2 = x
x - 3 / 4x = 1/2
Por lo tanto, la ecuación correcta de la opción es: 3 / 4x + 1/2 = x
