Let \mathbf u\in\mathbb R^2, where

\mathbf u=(u_1,u_2)

and let k\in\mathbb R be any real constant.

Given this definition of scalar multiplication, we can see right away that there is no identity element e such that

e\mathbf u=\mathbf u

because

e\mathbf u=e(u_1,u_2)=(eu_1,0)\neq(u_1,u_2)=\mathbf u

¿Cuál es el valor de 0.1561 redondeado a la décima más cercana?
Alik [6]

Answer: 0.2

Step-by-step explanation: Necesitamos ajustar la estimación de 0.1561 al décimo más cercano.

El número después del decimal es el número en el décimo lugar. Considere el número a un lado del lugar de las décimas y utilice el número para decidir si se reunirán o seguirán siendo el equivalente. Observe que el número a un lado del décimo lugar es mayor o equivalente a 5 o menos de 5. En el caso de que ese número sea más digno de mención o equivalente a 5, en ese punto el número se reunirá aún en la remota posibilidad de que ese número es menor de 5, en ese momento el número no se reunirá. Permanecerá igual.

Consideremos el número dado 0.1561

El número en el lugar de las décimas es 1

El número después del punto de las décimas es 5 (que es más prominente o equivalente a 5)

De esta manera, el número se reunirá en 0,2

Fill in the table. I will pick brainliest.
Nana76 [90]

Answer:

Start: Brown feather % is  97% Grey feather % is 3%

End: Brown feather % is  19% Grey feather % is 81%

Step-by-step explanation:

Start:

There is 700 total feather (679+21) so to get to 100(the denominator for percentages) you have to divide by 7

divide each number by 7(679/7 and 21/7)

and you get 97 and 3 which will be your percentages

End:

There is 740 total feather (140+600) so to get to 100(the denominator for percentages) you have to divide by 7.4

divide each number by 7.7(140/7.4 and 600/7.4)

and you get about 19(rounded) and about 81(rounded) which will be your percentages

Hope this helps!!!

Which equation is equivalent to –k + 0.03 + 1.01k = –2.45 – 1.81k
Nat2105 [25]
-k + 0.03 + 1.01K = -2.45 - 1.81k
0.01k + 0.03 = -2.45 - 1.81k
0.01k + 1.81k = -2.45 - 0.03
1.82k = -2.48
