4 AnswersMathematics1 decade agoCan someone explain to me how to get exact and approximate solutions to three decimal places?
y^2-6y+9=36
This is what I have. Can someone tell me if I have done this correctly.
y^2-6y+9=+/-6
(y^2-9)=+/-6
9+6=15
9-6=3
So, I got that the solutions would be 15,3... is that right?
3 AnswersMathematics1 decade agohow do you find the vertex in the equation f(x)=-2x^2+2x+8?
I figured out most of it, but I can not seem to figure out how they got the final answer.
I know the line of symmetry is 1/2 so the equation becomes f(1/2)=2(1/2)^2+2(1/2)+8
and I know the answer turns out to be 17/2, but I have NO IDEA how they got 17. Can someone explain it to me?
3 AnswersMathematics1 decade agoWhen does the baby start to hear outside of the uterus?
I am 11 weeks. My husband is in Iraq and I want to know when I should start putting him on speakerphone so he can talk to the baby. He won't be back until the birth, but I still want my little nudger to know his/her daddy's voice before then.
1 AnswerPregnancy1 decade agoNine weeks and stomach is obviously getting larger...?
I am nine weeks pregnant and my stomach seemed to start rounding out at 6 weeks or so. Is that normal? I haven't gained any weight on the scale or anything, but even my clothes are starting to not fit right. I know it's normal to get baby bump faster with the second but this is only my first. My friends have even started pointing it out. I'm not worried or anything, just curious. Any help would be greatly appreciated. :) Thanks.
