Responder:
24 días
Explicación paso a paso:
Dado que:
Total de páginas = 288
Número de páginas leídas por día = 12
Número de días que se necesitarán para leer el libro completo:
Total de páginas / número de páginas leídas por día
288/12
= 24
Por lo tanto, a María le tomará 24 días leer el libro completo, si lee 12 páginas del libro por día.
Answer:
-6i
Step-by-step explanation:
Complex roots always come in pairs, and those pairs are made up of a positive and a negative version. If 6i is a root, then its negative value, -6i, is also a root.
If you want to know the reasoning, it's along these lines: to even get a complex/imaginary root, we take the square root of a negative value. When you take the square root of any value, your answer is always "plus or minus" whatever the value is. The same thing holds for complex roots. In this case, the polynomial function likely factored to f(x) = (x+8)(x-1)(x^2+36). To solve that equation, you set every factor equal to zero and solve for the x's.
x + 8 = 0
x = -8
x - 1 = 0
x = 1
x^2 + 36 = 0
x^2 = -36 ... take the square root of both sides to get x alone
x = √-36 ... square root of an imaginary number produces the usual square root and an "i"
x = ±6i
Answer:
Approximately 4 gallons
Step-by-step explanation:
Step-by-step explanation:
First you do the one in the parentheses: 4 - 6 = -2
Then you got the answer: -2
Then you add -2 + 1 = -1
You got the answer: -1
Hello,
(x-(-1+4i))(x-(-1-4i))=((x+1)-4i)((x+1+4i)
=((x+1)²+16
=x²+2x+17
