Para redondear este número a 1,000, verifiquemos el tercer dígito del número.
Si el dígito es mayor que 5, aumentamos el siguiente número en 1 unidad.
Si el dígito es menor o igual a 5, mantenemos el siguiente número.
El tercer dígito es 3, por lo que el número redondeado es:
So first, we know negatives are the least. comparing, -2 and -2.1, we can obviously see that -2.1 comes first
so we have -2.1, -2
then, the positives. you have 2.1, 2, and 2 1/11 first we know 2 is the least of them. so now we just need to figure out if 2.1 is greater than or less than 2 1/11. we can convert the decimal to a fraction. so 2.1 is 2 1/10 and 1/10 is greater than 1/11. so it goes 2, 2 1/11, 2.1
then putting it all together: -2.1, -2, 2, 2 1/11, 2.1
We have the operation:
(2n² + 1)/3
2n (n/3) + 1/3
Since we are to use the condition that 3 does not divide n, we have:
n/3 = q +r/3
n = 3q + r
where q is the quotient and r is the remainder and not divisible by 3 or equal to 0
both q and r are whole numbers
Substituting,
2(3q + r) (q + r/3) + 1/3
6q² + 4qr + 2r²/3 + 1/3
6q² + 4qr + (2r² + 1)/3
The term:
(2r² + 1)/3
will only be a whole number if r is not divisible by 3 or equal to 0, which means that
(2n² + 1)/3
is a whole number if and only if
n/3 is not a whole number
ANSWER
The correct answer is .
<u>EXPLANATION</u>
We were given the matrix equation;
.
We must first simplify the Left Hand Side of the equation by adding corresponding entries.
.
That is;
.
Since the two matrices are equal, their corresponding entries are also equal. we equate corresponding entries and solve for m and n.
This implies that;
We got this equation from row one-column one entry of both matrices.
Also, the row three-column three entries of both matrices will give us the equation;
Hence the correct answer is .
The correct option is option 2
Answer:
The sequence is recursive and can be represented by the function f(n + 1)= f(n) + 3/8
