Answer:

B) No Unique Solutions

Step-by-step explanation:

Given:

$z=x+5y-14$

$-2y=-4\\y={-4}{-2}=2$

$3x+y-3z=14$

now we now the value of y = 2 so we will substitute in equation $z=x+5y-14$

$z=x+5\times2-14\\z=x+10-14\\z= x-4$

Now, We have value of y=2 and value of $z=x-4$ Substituting in both the value in equation $3x+y-3z=14$

$3x+2-3(x-4)=14\\3x+2-3x+12=14\\14=14$

which means that the equation has Infinite solutions.

For what values of k

sergey [27]

If y = cos(kt), then its first two derivatives are

y' = -k sin(kt)

y'' = -k² cos(kt)

Substituting y and y'' into 49y'' = -16y gives

-49k² cos(kt) = -15 cos(kt)

⇒ 49k² = 15

⇒ k² = 15/49

⇒ k = ±√15/7

Note that both values of k give the same solution y = cos(√15/7 t) since cosine is even.

$\huge \boxed{ \green{ANSWER}}$

$\underline{v = 13 \: 520 \: {m}^{3} }$

$\huge \boxed{ \red{SOLUTION}}$

$v = lwh \\ = (52m) \: (13m) \: (20m) \\ \implies \underline{v = \: 13 \: 520 \: {m}^{3} }$
