What is the solution to 3 times the square root of 4 minus 2 times the square root of 4? A. 0 B. 1 C. 2 D. 3
olasank [31]

For this case we have the expression:

"the square root of 4" is represented algebraically as:

\sqrt {4}

Then, we can express the given statement as:

3 \sqrt {4} -2 \sqrt {4} =

They are similar terms, we can subtract:

3 \sqrt {4} -2 \sqrt {4} = \sqrt {4} = \sqrt {2 ^ 2}

By definition of power properties we have that:

\sqrt [n] {a ^ n} = a ^ {\frac {n} {n}} = a

Then the expression is reduced to:

\sqrt {2 ^ 2} = 2

Answer:

3 \sqrt {4} -2 \sqrt {4} = 2

3. A submarine dives at an
Vesna [10]

Answer:

The height of deepness of submarine is 424.1 feet  

Step-by-step explanation:

Given as :

The angle at which submarine drives of the surface of water = Ф = 13°

The speed at which submarine travel = s = 760 feet per minute

Let The height of deepness of submarine = h feet

The time taken to reach that deepness = t = 5 minutes

<u>According to question</u>

The height of deepness of submarine = \dfrac{\textrm speed}{\textrm time}

i.e h × cos(90 - Ф) = \dfrac{s}{t}

Or,  h × Sin(Ф) = \dfrac{\textrm 760 feet per min}{8 min}

Or,  h × Sin(13°) = 95 feet

Or,   h × 0.224 = 95 feet

∴  h = \dfrac{95}{0.224}

i.e h = 424.10 feet

So, The height of deepness of submarine = h = 424.10 feet

Hence, The height of deepness of submarine is 424.1 feet  Answer
