Graph the function f(x)=1/2 sqrt(x+1)
goldenfox [79]

The function is defined only if x+1 \geq 0 \iff x \geq -1. So, the leftmost point is x=-1, and we have


f(-1)=\frac{1}{2}sqrt(-1+1) = 0


So, the first point is (-1,0)


The three additional points seem arbitrary, so let's choose x=0,1,2. We have:


f(0)=\frac{1}{2}sqrt(0+1) = \frac{1}{2}


So, the second point is (0,\frac{1}{2})


f(1)=\frac{1}{2}sqrt(1+1) = \frac{\sqrt{2}}{2}


So, the third point is (1,\frac{\sqrt{2}}{2})


f(2)=\frac{1}{2}sqrt(2+1) = \frac{\sqrt{3}}{2}


So, the fourth point is (2,\frac{\sqrt{3}}{2})

X = 20

Square both sides:
5x = 100
x = 20

triangle AMY ~ MEG , AM = 5 MY=7 AY =3. MEG IS A DILATION of AMY by a scale facyor of 1/3. fimd the perimeter of MEG.
Mademuasel [1]

Answer:

7

Explanation:

From the question, we're told that triangles AMY and MEG are similar. If triangle AMY has sides AM = 5, MY = 7, and AY = 3 then we can find the side lengths of triangle MEG since we're told from the question that it is a dilation of AMY by a scale factor of 1/3.

So all we need to is multiply the corresponding sides of AMY by 1/3, so we'll have;

\begin{gathered} ME=5\ast\frac{1}{3}=\frac{5}{3} \\ EG=7\ast\frac{1}{3}=\frac{7}{3} \\ MG=3\ast\frac{1}{3}=3 \end{gathered}

We can then go ahead and find the perimeter of MEG. Note that to find the perimeter of a triangle, we add all the length of its sides;

\begin{gathered} \text{Perimeter of MEG}=\frac{5}{3}+\frac{7}{3}+3 \\ =\frac{5+7+9}{3} \\ =\frac{21}{3} \\ =7 \end{gathered}

The perimeter of MEG is 7.
