Given a discriminat of 36 how many solutions with the quadratic function have?

2

Step-by-step explanation:

So!

If the d (discriminant)

d > 0 Then 2 solutions

d = 0 Then 1 solution

d < 0 Then none

36 > 0 so 2 solutions

2 Rational Roots!

Step-by-step explanation:

If the discriminant or D

If D > 0 Then there are 2 solutions

If D = Positive Perfect Square then there are 2 Rational roots

If D = Positive Non Perfect Square then there are 2 Irational roots

If D = 0 Then there is 1 solution

If D < 0 Then there are no real roots or 2 complex roots

D or 36 > 0 and D is a perfect square so

2 Rational Roots!

in the opening of the question the word 'service' is associated only with the pretax value.

the closing part of the question asks: how much did she pay for the  

service

−−−−−−  

so technically the answer is

87.12

however, the intention of the question provider may have been that your answer is to be  

$

87.12

(

1

+

8

)

=

$

94.09

to 2 decimal places.
