Olin [163]3 years ago
5 0

Step-by-step explanation:

<em>Here </em><em>we </em><em>can </em><em>see </em><em>it </em><em>is </em><em>an </em><em>isosceles </em><em>triangle </em><em>so </em><em>base </em><em>angles </em><em>are </em><em>equal </em>

<em>x </em><em>+</em><em> </em><em>x </em><em>+</em><em> </em><em>8</em><em>0</em><em>°</em><em> </em><em>=</em><em> </em><em>1</em><em>8</em><em>0</em><em>°</em><em><</em><em>Being </em><em>sum </em><em>of </em><em>angles </em><em>of </em><em>triangle </em><em>></em>

<em>2x </em><em>=</em><em> </em><em>1</em><em>8</em><em>0</em><em>°</em><em> </em><em>-</em><em> </em><em>8</em><em>0</em><em>°</em>

<em>2x </em><em>=</em><em> </em><em>1</em><em>0</em><em>0</em><em>°</em>

<em>Therefore </em><em>x </em><em>=</em><em> </em><em>5</em><em>0</em><em>°</em>

Find the minimum value if f(x) = xe^x over [-2,0]
SashulF [63]

Given function:

f(x)=xe^x

The minimum value of the function can be found by setting the first derivative of the function to zero.

f^{\prime}(x)=xe^x+e^x\begin{gathered} xe^x+e^x\text{ = 0} \\ e^x(x\text{ + 1)  = 0} \end{gathered}

Solving for x:

\begin{gathered} x\text{ + 1 = 0} \\ x\text{ = -1} \end{gathered}\begin{gathered} e^x\text{ = 0} \\ \text{Does not exist} \end{gathered}

Substituting the value of x into the original function:

\begin{gathered} f(x=1)=-1\times e^{^{-1}}_{} \\ =\text{ -}0.368 \end{gathered}

Hence, the minimum value in the given range is (-1, -0.368)
