<u>Answer</u><u>:</u>

  • b =  \sqrt{ {c}^{2}  -  {a}^{2} }

<u>S</u><u>t</u><u>e</u><u>p</u><u>-</u><u>b</u><u>y</u><u>-</u><u>S</u><u>t</u><u>e</u><u>p</u><u> </u><u>Explanation</u><u>:</u>

In the given right-angled triangle, the largest angle is 90°. And side c is opposite to it, hence c is the hypotenuse.

Then, a and b are the leg sides of the triangle i.e. base and perpendicular. Then, By using Pythagoras theoram:

\longrightarrow{{a}^{2}  +  {b}^{2}  =  {c}^{2}}

Now shifting a² by subtracting from both sides,

\longrightarrow{{b}^{2}  =   {c}^{2}  -  {a}^{2}}

We need b, square rooting both sides

\longrightarrow{b =  \sqrt{ {c}^{2}  -  {a}^{2} }}

That is Option B. And we are done! :D

Answer:

 none of the above

 f(x) ≈ 197·1.03^x; approximately 3% daily

Step-by-step explanation:

If we let x represent days, then x/7 represents weeks and we can rewrite f(x) as ...

 f(x/7) = 197·1.25^(x/7) = 197·(1.25^(1/7))^x

 f(x) ≈ 197·1.03^x

__

The daily multiplier of 1.03 represents a daily growth rate of

 1.03 -1 = .03 = 3%
