Answer:

That would be 9 my good sir ( or ma'am )

Step-by-step explanation:

basicly round the 61 so that there would not be a remainder and divide 54 by 6 you will get 9, so therefore the same case is for 540 by 60.

Find the volume of the parallelepiped with adjacent edges t = 3j – 4j – 6k, u = 3i – 7j – 7k and v = 5i + j + 3k.

Assoli18 [71]

Answer:

94 cubic units

Step-by-step explanation:

The volume of this parallelepiped (the product of area of its base and height) is equal to the absolute value of the scalar triple product $|\vec{t}\cdot (\vec{u}\times \vec{v})|$

Since

$\vec{t}=3\vec{i}-4\vec{j}-6\vec{k}=(3,-4,-6)\\ \\\vec{u}=3\vec{i}-7\vec{j}-7\vec{k}=(3,-7,-7)\\ \\\vec{v}=5\vec{i}+\vec{j}+3\vec{k}=(5,1,3)$

we have

$|\vec{t}\cdot (\vec{u}\times \vec{v})|=\left|\left|\begin{array}{ccc}3&-4&-6\\3&-7&-7\\5&1&3\end{array}\right|\right|=|3\cdot (-7)\cdot 3+(-4)\cdot (-7)\cdot 5+3\cdot 1\cdot (-6)-5\cdot (-7)\cdot (-6)-3\cdot (-7)\cdot 1-3\cdot (-4)\cdot 3|=|-63+140-18-210+21+36|=|-94|=94\ un^3.$

Does this matrix have an inverse?why or why not ?

Ierofanga [76]

Answer:

C. No, because it's determinant is zero

Step-by-step explanation:

$A= \begin{bmatrix} 16 & - 4\\\\ 8 & - 2\end{bmatrix}$

$det(A) =\begin{vmatrix} 16 & - 4\\\\ 8 & - 2\end{vmatrix}$

$det(A) = 16\times (-2)-(-4)\times 8$

$det(A) = -32+32$

$det(A) = 0$

2/8=1/4 so 1/4 of 4000 is 1500. 1500/2=750 people. 1500+750=2250. 2250/16000=0.1406 Multiply 0.1406 by 100 and you get 14.06 and then round.

Assume you invest $3,000 in an account that pays 7% compounded monthly. How much money will be in the account after 6 years?

omeli [17]

Use A = P(1+r/n)^(nt).

Here, A = $3000(1+0.07/12)^(12*6). Can you evaluate this?
