Answer:

3.012 Yards

If that is an answer choice (which I suppose it is, as I have the sme question).

I will explain why:

Firstly the answer choices (A: 2.998, B. 3.001, C: 2.999) all fall below 3.002 yards, even though they aren't enough, it is still within a reasonable range, far closer to 3.002 than 3.012. Therefore, It would be your answer!~

Answer:

(a, b) = (-2, -1)

Step-by-step explanation:

The transpose of the given matrix is ...

$A^T=\left[\begin{array}{ccc}1&2&a\\2&1&2\\2&-2&b\end{array}\right]$

Then the [3,1] term of the product is ...

$(A\cdot A^T)_{31}=\left[\begin{array}{ccc}a&2&b\end{array}\right]\cdot\left[\begin{array}{ccc}1&2&2\end{array}\right]=a+2b+4$

and the [3,2] term is ...

$(A\cdot A^T)_{32}=\left[\begin{array}{ccc}a&2&b\end{array}\right]\cdot\left[\begin{array}{ccc}2&1&-2\end{array}\right]=2a-2b+2$

Both of these terms in the product matrix are 0. We can solve the system of equations by adding these two terms:

(a +2b +4) +(2a -2b +2) = (0) +(0)

3a +6 = 0

a = -2

Substituting for 'a' in term [3,1] gives ...

-2 +2b +4 = 0

b = -1

The ordered pair (a, b) is (-2, -1).

What is 4x-2+x=-2+2x

Vsevolod [243]

Answer:

x= no solution

Step-by-step explanation:

4x-2+x=-2+2x

We first add 4x+x on the left side.

5x-2=2+2x

We then add 2 to both sides.

5x=2x

The answer is no solution because we got no answer out of the equation.

Kryger [21]

Answer:4.6 liter

Step-by-step explanation:

Given

Helena family is 4600 milliliter

and we know

1 liter is equal to 1000 ml

and 1 ml is equal to 0.001 m

So, 4600 ml is equal to

$\Rightarrow 4600\times 0.001$

$\Rightarrow 4.6\ liter$
