Answer:

See proof

Step-by-step explanation:

Statements Reasons

1. $\overline{AEC}$ bisects $\angle DAB,\ \angle 1\cong \angle 2$ Given

2. $\angle 3\cong \angle 4$ Definition of angle bisector

3. $\overline{AE}\cong \overline{AE}$ Reflexive property of equality

4. $\triangle ABE \cong \triangle ADE$ AAS postulate

5. $\overline {AB}\cong \overline{AD}$ Congruent triangles have congruent corresponding sides

6. $\overline{AC}\cong \overline{AC}$ Reflexive property of equality

7. $\triangle BAC \cong \triangle DAC$ SAS postulate

8. $\overline {BC}\cong \overline{CD}$ Congruent triangles have congruent corresponding sides

The curve with equation y=e^2x/4+3e^x has one stationary point.find the exact value of the coordinates of this point

Softa [21]

$y=\dfrac{e^{2x}}{4+3e^x}$
$\implies y'=\dfrac{2e^{2x}(4+3e^x)-3e^xe^{2x}}{(4+3e^x)^2}$
$\implies y'=\dfrac{8e^{2x}+3e^{3x}}{(4+3e^x)^2}$

Stationary points occur where the derivative is zero. The denominator is positive for all $x$ , so we only need to worry about the numerator.

$8e^{2x}+3e^{3x}=e^{2x}(8+3e^x)=0$

$e^{2x}>0$ for all $x$ , so we can divide through:

$8+3e^x=0\implies e^x=-\dfrac83$

But $e^x>0$ for all $x\in\mathbb R$ , so this function has no stationary points...

I suspect there may be a typo in the question.

Classify the triangle as acute, right, or obtuse and classify it as equilateral, isoceles, or scalene.

Vsevolod [243]

I think it’s the one with acute because it’s less than 90 degrees
