Answer 7

right

Answer 8

oh wow thanks!! Can you help with just 2 more?

Answer 9

ok.

its B

Answer 19

oh ok.... i get it just was stuck in the moment

Answer 20

what about this: Find an explicit rule for the nth term of the sequence.

2, -8, 32, -128, ...

an = 2 ● 4n+1
an = 2 ● (-4)n
an = 2 ● 4n-1
an = 2 ● (-4)n-1

Answer 21

I appreciate your help kind person!

Answer 22

what is a2/a1?

Answer 23

a2

Answer 24

a2 means second term a1 is 1st term.

I wrote them on my online paper

Answer 28

its d

Answer 29

oh my online paper told me that but i got confused

Answer 30

The focus is always inside the parabola
The focus is on the y-axis, so the parabola is vertical therefore y is function of x

Use following equation
\[y = \frac{1}{4p} x^2\]
where "p" is distance from vertex to focus
Here assume vertex is origin (0,0)

Answer 31

what would the final solution be?

Answer 32

Answer 39

ok. let me check. wait a bit

Answer 40

See the distance of any point on the parabola and the perpendicular distance from the directrix will be same. so

Answer 41

\[\sqrt{(x-0)^2+(y-6)^2}=\sqrt{(y+6)^2}\]

Answer 42

so. x^2+y^2-12y+36=y^2+12y+36
so x^2=24y

Answer 43

now you tell me the answer

Answer 44

y= (1/24) x^2

Answer 45

oh ok thats what i got before. Thanks! I missed the x^2 though

Answer 46

i think 6/5...

Answer 47

\[f(x)=-10/x\]

Answer 48

yes..

Answer 49

what is f'(x)?

Answer 50

Answer 51

im bad at explaining how i get somewhere

Answer 52
