Answer:

a=0, b=16, of the pair (0,16)

Step-by-step explanation:

You want to prove the following: There are real numbers a and b such that \sqrt{a+b}=\sqrt{a}+\sqrt{b}

So, to prove this, it is enough to find a pair (a,b) of real numbers for which the equation holds true. There are infinite of such pairs, but one example is (0,16). Indeed:

\sqrt{a+b}=\sqrt{0+16}=\sqrt{16}=4=0+4=\sqrt{0}+\sqrt{16}=\sqrt{a}+\sqrt{b}

In fact, (0,m) or (n,0) ara valid pairs, for nonnegative numbers m,n. Even more is true; these are the only pairs which satisfy the equation.

Ket [755]

The percent error is 4.167 %

<em><u>Solution:</u></em>

Given that, Mrs Franklin's speedometer said she was driving at a rate of 48 miles per hour

When checking the accuracy of her speedometer, an Automotive Specialist recorded her speed at 50 miles per hour

<em><u>The percent error is given by formula:</u></em>

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

\text{Percent error } = \frac{\text{experimental-theoretical}}{theoretical} \times 100

From given,

Experimental value = 50

Theoretical value = 48

<em><u>Substituting the values in formula, we get,</u></em>

Percent\ Error = \frac{50-48}{48} \times 100\\\\Percent\ Error = \frac{2}{48} \times 100\\\\Percent\ Error = 4.167

Thus the percent error is 4.167 %

lys-0071 [83]

The numerical representation and final elevation of the fish relative to sea level are :

  • Final position = -13.52 + 7.8
  • Final position = - 5.72

<u>Given the Parameters</u> :

Initial depth of fish = - 13.52

Change in elevation of fish = 7.8 feets

Positions below sea level are represented as negative values (-) ;

Hence, initial position of fish = - 13.52

Change in position = Rise in depth of 7.8 feets

<u>The numerical representation of the final position of the </u><u>fish</u><u> </u><u>can</u><u> </u><u>be</u><u> written thus</u> :

  • Final position = Initial position + change in position

  • Final position = - 13.52 + 7.8

Hence, the final position of the fish will be :

  • Final position of fish = -13.52 + 7.8 = - 5.72
