Answer:

Step-by-step explanation:

The height of the door is given as 10 feet. The bottom 1/2 has a height of 5 feet.

The width of one door = 12/2 = 6 feet.

The value for x^2 = 5^2 + 6^2

x^2 = 25 + 36

x^2 = 61

sqrt(x^2) = sqrt(61)

x = 7.81

The closest value = 8

$\bf \textit{we know that }
\begin{cases}

p=100
\end{cases}\implies 100=\cfrac{k\sqrt[3]{48820}}{78.7}
\\\\\\
100\cdot 78.7=k\sqrt[3]{48820}\implies \cfrac{7870}{\sqrt[3]{48820}}=k
\\\\\\
thus\qquad \boxed{p=\cfrac{\frac{7870}{\sqrt[3]{48820}}\sqrt[3]{w}}{s}}
\\\\\\
\textit{now, what is \underline{p} when }
\begin{cases}
w=54,688\\
s=72.6
\end{cases}?\implies p=\cfrac{\frac{7870}{\sqrt[3]{48820}}\sqrt[3]{54688}}{72.6}$

now, if that value is less than 100, then the fellow is "undernourished", otherwise, is overfed.

Given the piecewise function shown below select all of the statements that are true please help

KengaRu [80]

Answer:

B and D

Step-by-step explanation:

Take a look at all the options x=4, 3, 1, 2 > 0

So, we just care about the domain where x>0, which is $f(x)=x^{2}$ .

Then plug in x we will have the right answer.

Explanation:

m || n
