#1:

A)

you need to know where a vertex goes on a isosceles triangle...

I attached a picture that explains it.....

you also want to label triangle.... XYZ

I put a picture on of how you should of labeled the triangle...

B)

so we need to find Measure for each angle.... REMEMBER: A triangle angles needs to = 180.

so your equations will need to be equal to 180.

4x+4+2x+2+7x-8=180

so we combine liked terms

4x+2x+7x=13x

4+2-8=-2

13x-2=180

+2 +2

13x=182

/13 /13

x=14

now you plug in X

4(14)+4= 60

2(14)+2= 30

7(14)-8= 90

now you want to check you answers so add them up to see if your answers equal 180...

60+30+90=180

to be continued.... i do second question on a second answer since i dont want pictures to get mixed up

Answer:

  $68.00

Step-by-step explanation:

Let s represent the opening price. Then the closing price is ...

  s - 3.25% × s = $65.79

  s(1 -0.0325) = $65.79 . . . . collect terms

  0.9675s = $65.79 . . . . . . . simplify

  s = $65.79/0.9675 . . . . . . .divide by the coefficient of s

  s = $68.00 . . . . . the opening stock price

What is the correct solution to the equation 1 – (2x + 4) = –4x + 5?
lions [1.4K]

\\ \sf\longmapsto 1-(2x+4)=-4x+5

\\ \sf\longmapsto 1-2x-4=-4x+5

\\ \sf\longmapsto -2x-3=-4x+5

\\ \sf\longmapsto -2x+4x=5+3

\\ \sf\longmapsto 2x=8

\\ \sf\longmapsto x=\dfrac{8}{2}

\\ \sf\longmapsto x=4

What is the maximum number of relative extrema a polynomial function can have?
creativ13 [48]
Relative extrema occur where the derivative is zero (at least for your polynomial function). So taking the derivative we get

<span>20<span>x3</span>−3<span>x2</span>+6=0

</span><span> This is a 3rd degree equation, now if we are working with complex numbers this equation is guaranteed to have 3 solutions by the fundamental theorem of algebra. But the number of real roots are 1 which can be found out by using Descartes' rule of signs. So the maximum number of relative extrema are 1.</span>
