A) is the answer!

It is a penny correct ????

because it simplifies to 59F-(59*32)

then if f goes up 1, celsius goes up 59.

no other cases work, so i think its A.

HOPE THIS HELPED!

12 pi

Multiplying 'x' by a fraction < 1  stretches the function out.......multiplying 'x' by a number > 1 shortens the period.

( take 2 pi and divide by the number that x is multiplied by to get the period

     example   cos 1/6 x    has a period of   2 pi /(1/6) = 12 pi

     example    cos 3x       has a period of    2pi/3

BD does bisect  angle ABC

[ The little notations at the apex angles of triangles CBD and ABD indicate equal angles ]

hello classmate

A penny has heads, and tails, is brown, and has no legs.

There may be more, too......!!!

i think the answer is yes but i dont know how to explain it

Cannot access this.....

the letter X

6.

D =  (-inf, - 4) U (-4, inf)

R = (-inf, 2) U (2, inf)

Function because it passes the vertical line test

9. 

D =   x < -1   U  x > -1

R =   y  < - 4   U  y > - 4  

Function because it passes the vertical line test

20.

k ( -δw)  =   -2(-δw) - 15

                  __________

                    (-δw) + 9

21.   t(x + 4)  =  ( x + 4)^3 + 2(x + 4)  =  

        (x + 2)^2 (x + 4)  + 2x + 8  =

(x^2 + 4x + 16) (x + 4) + 2x + 8  =

x^3 + 4x^2 + 16x + 4x^2 + 16x  + 64 + 2x + 8  =

x^3 + 8x^2 + 34x + 72

Here is one way:

1st. Seq. = 0, -1, -1, 0, 2, 5, 9, 14, 20, 27, 35, 44........etc.
2nd. Seq =-1,  0,  1, 2,  3, 4, 5, 6,  7,   8,   9,   10.........etc.
The closed form of the 1st. sequence is:
1/2{n - 4}{n - 1}
Therefore, the 5th term of the 1st sequence is:
= 2.

I could be wrong but is it a penny? Because coins have a head and tail. The penny is the only coin that is brown.

A grizzly bear with it's legs chopped off, Ha...or maybe a brown snake...or even better a cane

I know right...I think the creators of this site truly are brilliant people.

My favorite thing is probably all the helpful people on this site to be honest. And the calculator too.

The period is 2 pi     which is the usual for sin and cos

the amplitude is reduced by 1/2 from the usual amplitude of 1

it is a cosine wave

1/2 cos x

My bad! I have such bad eyes, jeez...

1.) Grogg draws an equiangular polygon with g sides, and Winnie draws an equiangular polygon with w  sides, where g is less than w. If the exterior angle of Grogg's polygon is congruent to the interior angle of Winnie's polygon, find w.

2.)

For number two, that's all of the information it gives me.. I'm assumming that we just figure it out without knowing exactly which is which? 

There is no question for #1

And for the second one, we need to know which angles are A, B, C, D.....etc.
