<u>ANSWER</u>

\binom{2 }{ - 2}

<u>EXPLANATION</u>

We were given the vector equation:

2 \binom{1}{1} ) - 4 \binom{0}{1}

We perform the scalar multiplications first to get:

\binom{2 \times 1}{2 \times 1} ) - \binom{4 \times 0}{4 \times 1}

Simplify the components of each vector

\binom{2 }{2} - \binom{0}{4}

We subtract the corresponding components of the vector to get:

\binom{2 - 0}{2  - 4}

This simplifies to

\binom{2 }{ - 2}

The Sunny Days Apartment building has a cylindrical, above ground pool in the yard. The radius of the pool is 2 times its height
garik1379 [7]

9514 1404 393

Answer:

  6.2 ft

Step-by-step explanation:

The volume of a cylinder is given by ...

  V = πr²h

Here, we have r=2h and V=3000 ft³. Putting these numbers into the formula and solving for h, we get ...

  3000 ft³ = π(2h)²h

  (3000 ft³)/(4π) = h³ . . . . . divide by the coefficient of h³

  h = ∛(750/π) ft ≈ 6.2 ft

The pool is about 6.2 feet deep.

What is 0.002 1/10 of
ki77a [65]
<span>0.002 1/10 of what
=> 1/10a = 0.002
=> Now, let’s multiply both sides with 10 to find the answer since we’re looking for the 1/10 of what number.
=> 10 x 1/10 a = 10 x 0.002
=>  a = 0.02

Thus, 0.002 is the 1/10 of 0.02 number.
let’s check if we have a correct answer.
To check just do the other way around, Divide our answer by 10.
=> 0.02 / 10
=> 0.002
Therefore, our answer is correct
