"m 1/n" is meaningless; if you want to indicate exponentiation, you must use the "^" symbol, as follows:

m^(1/n)

If you now wish to raise this to the power n, do this:

[m^(1/n)]^n Here we can mult. the 2 exponents together, obtaining m^1, or just plain m.

Mark the statement either true (in all cases) or false (for at least one example). If false, construct a specific example to sho

LUCKY_DIMON [66]

Answer with Step-by-step explanation:

We are given that $v_1,v_2,..,v_4$ are in $R^4$ and $v_1,v_2,v_3$ is linearly dependent then {v_1,v_2,v_3,v_4}[/tex] is also linearly dependent.

We have to find that given statement is true or false.

Dependent vectors:Dependent vectors are those vectors in which atleast one vector is a linear combination of other given vectors.

Or If we have vectors $x_1,x_2,....x_n$

Then their linear combination

$a_1x_1+a_2x_2+.....+a_nx_n=0$

There exist at least one scalar which is not zero.

If $v_1,v_2,v_3$ are dependent vectors then

$a_1v_1+a_2v_2+a_3v_3=0$ for scalars $a_1,a_2,a_3$

Then , by definition of dependent vectors

There exist a vector which is not equal to zero

If vector $v_3$ is a linear combination of $v_1\;and \;v_2$ , So at least one of vectors in the set is a linear combination of others and the set is linearly dependent.

Hence, by definition of dependent vectors

{ $v_1,v_2,v_3,v_4$ } is linearly dependent.

Option B is true.

About 23/40 of a lawn is planted with kentucky bluegrass. what percent of the lawn is planted with bluegrass?

Alisiya [41]

To find the percentage of a fraction, we first divide the numerator by the denominator

23/40 = 0.575

Then, we multiply it by 100 in order to find the percentage.

(100)(0.575) = 57.5%

This is your final answer.
