Question

i cant figure out the answers to these questions ive been trying to solve them since yesterday morning. someone please help!!??
1. write the polyomial in sandard fom. Then name the polyomial based on its degree ad number of terms.
6 - 12x + 13x^2 - 4x^2
A. 9x^2 - 12x; quadratic binomial
B. 9x^2 - 12x + 6; qadratic trinomial
C. -3x^2 + 6; quadratic binomial
D. 9x^2 - 12x - 6; cubic trinomial

2. A bioligist studied the populations of common guppies and endlers guppies over a 6-year period. The biologist modeled the populations, in tens of thousands, with the following polynomi

Answer 1

If you have \(x\times x\) you can say \(x^2\), right?

Answer 2

yea

Answer 3

Or \(x\times x\times x\times x\times x=x^5\)
We use the little number to say how many times we multiply the same number over and over.

Answer 4

ok

Answer 5

so is it lke 29x^5 or im not sure

Answer 6

If we do that three times we can cay\[3x^2=(x\times x)+(x\times x)+(x\times x)\]

Answer 7

oh okay

Answer 8

or \(3x^2+2x^2 = (x\times x)+(x\times x)+(x\times x)+(x\times x)+(x\times x)\)
which is just five times doing that \((x\times x)\)

Answer 9

ok that makes a whole lot more since now

Answer 10

You have \(6 - 12x + 13x^2 - 4x^2\)
and see you have 13-4 of the x squared

Answer 11

so 13x^2 is like saying (x times x) 13 times

Answer 12

yup

Answer 13

so now its 9x^2

Answer 14

?

Answer 15

Quite literally 9 times (x times x).
Yes

Answer 16

ok thanks!! (:

Answer 17

Do you own a bicycle?

Answer 18

yea y?

Answer 19

What about a tricycle?

Answer 20

uh no

Answer 21

So you only own one polycycle?

Answer 22

polycycle?

Answer 23

Poly, some number of.
Like polynomial, here you have three different parts, so you have a tri-nomial.

Answer 24

oh ok

Answer 25

wat about cubic or quadratic? how do i know that?

Answer 26

quadratus is latin for square

Answer 27

ok

Answer 28

cubic means cubed or to the three \(x^3\)

Answer 29

ok i forgot about that thank you so so so so much!!

Answer 30

Happy to help
