New Attached File Question!

Answer 1

I have no clue!

Answer 2

Q.6 use formula quadratic equation :
x=[-b+-sqrt(b^2-4ac)]/2a

Answer 3

x^2-3x-5=0, gives a=1 b=-3, and c=-5
plug of them to formula above

Answer 4

is it d?

Answer 5

it should get
x=[3+-sqrt(29)]/2
B

Answer 6

Oh, OMG! Thx! That's what I meant. :)

Answer 7

9.06] Using graphing technology, approximate the solutions of 0.35x2 − 2.52x + 1.34 = 0.

x ≈ 0.12 and x ≈ 4.56

x ≈ 0.58 and x ≈ 6.62

x ≈ 1.17 and x ≈ 6.14

x ≈ 1.83 and x ≈ 4.84
Do you know this one?

Answer 8

actually, i dont like using graph.. but i like by quadratic formula like before
x=[-b+-sqrt(b^2-4ac)]/2a
x=[2.52 +- sqrt((-2.52)^2 - 4*1*1.34)]/2*0.35
x=[2.52 +- sqrt(6.3504-5.36)]/0.7
x=[2.52 +- sqrt(0.9904)/0.7
x=[2.52 +- 0.995]/0.7
x1=(2.52+0.995)/0.7=...
x2=(2.52-0.995)/0.7=...

Answer 9

Ugh, I don't know. :(

Answer 18

I think it is C, right?

Answer 19

i got :
x1=(2.52+0.995)/0.7=5.021...
x2=(2.52-0.995)/0.7=2.178...
hmmm... there is no in option
maybe, i have used nearest not good here

Answer 20

Is it C though?

Answer 21

idk, obviously i got 5.021 and 2.178
soory if i was mistake calculate it

Answer 22

it is kay! LOL, thx for your help, have to go, byeee!!!

Answer 23

welcome, byee :D
