Question

can someone plz explain and help me put this into standard form >>> Y=0.05x^2+x+1?

Answer 1

Y=0.05x^2+x+1
This is in standard form for a parabola, which you have. Do you mean vertex form?
vertex form = y= a(x-h)2+k

Answer 2

yes thank you now I know why no one answers my question srry.

Answer 3

Ok one sec let me type it out. You just want the answer or would you want me to explain?

Answer 4

explain. and show.

Answer 5

kk give me a sec

Answer 6

okay.

Answer 7

is the vertex (.25,0)?

Answer 8

Grrr was typing out a huge tutorial and some how it got wiped lol

Answer 9

Got to the x of the vertex, which will be 10

Answer 10

omg. that sucks.srry

Answer 11

so my answer is wrong?

Answer 12

Ok we need to find the vertex. To find the vertex we use the Y=0.05x^2+x+1 equation
and the formula \( \frac{b}{2(a)} \)
b = x =1
a = .05

\[ \frac{1}{2(.05)} \]
\[ \frac{1}{.1} = 10 \]

Ok our x for our vertex = 10 now to find the y for our vertex point we need to insert 10 for x in the equation Y=0.05x^2+x+1

\[ Y=0.05(10)^2+10+1 \]
\[ Y=0.05(100)+10+1 \]
\[ Y=5+10+1 \]
\[ Y=11 \]

Now we have our y = 11 so our vertex is (10,11) so to put this in vertex form we plug our points in to y= a(x-h)^2+k

a = 0.05
x = x
h = vertex x 10
k = vertex y 11

Now just plugin
\[y= a(x-h)^2+k \]
\[y= 0.05(x-10)^2+11 \]

Answer 13

just give me a sec to read it over plz

Answer 14

Sorry, where ever you see 11 it should be 16

Answer 15

I was rushing that time around lol

Answer 16

oh okay so y=16 then?

Answer 17

yes

Answer 18

lol that's fine , I'm glad you took the time to help me out.

Answer 19

so the axis is -16?

Answer 20

Also, remember the x of the vertex can be found using \( \frac{b}{2(a)} \) which will give you the x of the vertex

Answer 21

no wait the axis would be -10.

Answer 22

is that right?

Answer 23

Yes

Answer 24

thank god.

Answer 25

okay , well thanks so much for helping me.

Answer 26

No problem anytime.

Answer 27

I am here to help with what I can

Answer 28

I know math can be frustrating lol

Answer 29

yah it really is , I have a short fuse for this stuff sometimes. lol

Answer 30

It is a lot harder too and more frustrating when you don't have anyone around to ask questions. That is why I like places like this :-)

Answer 31

ikr , I totally agree, I'm glad I found this place.

Answer 32

Ok have a good one. I will see ya around

Answer 33

kk. u2.
