The answer is D. Need anymore help, let me know.

D. Evan studied twice as long as Ted. 

Ted studied 3 hours and Evan studied for 6 hours. 

It's cool. Happens to me all the time mate.

Psh this was so easy wth I read the question incorrectly 

The answer is C, 3 seconds. 

Anything else, let me know.

Knew it! Thanks!!

Note that the function is at a max  at  x   =  2

From there....the function decreases as we move to the right...so...it decreases on    ( - 2, inf )  =   2 < x < inf ⇒ "C"

  {  Positive infinity is to the right....negative infinity is to the left.... on the x axis }

I think that you are getting confused..."interval"  usually refers to  the   x axis  values

The function decreases to -infinity along the y axis  as we move to the right

So  we can say that, as we move toward infinity on the x axis....the function decreases to -infinity along the y axis

Does that make sense....???

19 + 5x > 26    where x is the average number of digs you must have in each game to break your record

Thank youuuu

If  b/a   is a root...then   ( ax  - b )  is a factor.....

To see this...set   

ax  - b  = 0   add b to both sides

ax  = b     ...divide both sides by a

x   = b / a

So...this means that  3/4 is a root   and  ( 4x - 3)  is a factor  ⇒  C

I forgot I even posted this, thank you! I already got the answer but it's good to know I was correct :D

feet

8.5 x 10-2  =  .085 miles x 5280  feet /1 mile   = 448.8 feet

A /  B  = 

[2.4 x 10^11 ]  / [ 8 * 10^9 ] =

[2.4 / 8 ]  *  [  10^11 / 10^9 ]    =

.3 * 10^2   =

30  times as great  

x^3  + x^2  - 8x  - 8     factor as

x^2 (x + 1)  - 8 ( x + 1) 

(x + 1)  (x^2  - 8)  =

(x + 1) (x  + √8) (x - √8 ) 

Setting each factor to 0 and solving for  x  produces  x  = -1, x = -√8  , x  = √8

So....three real roots ⇒   "B"

1L  = 1 Kg...so

[ 3.5 x 10^ (-2) ]  *  [2.64 x 10^20   ]  =

[3.5 x 2.64  ]x  [ 10^(-2) * 10^(20 ]   =

9.24 x  10^18   Kg

3x^5  - 2x  + 1    =   0 

-1 is a root because   3(-1)^5  - 2(-1) + 1   =  -3 + 2 + 1  = 0

Look at the graph here : https://www.desmos.com/calculator/3lxzwfyib2

The graph never  intersects the  x axis again...so the remaining roots are complex

WolframAlpha shows that the polynomial has 4  remaining complex roots : 

https://www.wolframalpha.com/input/?i=3x%5E5%C2%A0+-+2x%C2%A0+%2B+1%C2%A0+%C2%A0+%3D%C2%A0+%C2%A00

 x ^3 +4x ^2+7x+6

-2 is a root because   (-2)^3  + 4(-2)^2  + 7(-2)  + 6  =   -8 + 16  - 14 + 6  = 0

So  (x + 2)  is a factor.....using synthetic division, we can find the remaining polynomial as follows

-2  [ 1    4     7      6  ]

            -2     -4    -6

     _______________

       1    2     3      0

The remaining polynomial is

x^2  + 2x  + 3   set to 0

x^2 + 2x + 3   = 0        subtract 3 from both sides

x^2  + 2x    =  -3        take 1/2 of 2  = 1...square it  = 1...add it to both sides

x^2 + 2x  + 1   = -3 + 1      factor the left side, simplify the right

(x + 1)^2   = -2       take both roots

x + 1  = ±√[-2]

x = 1  = ±√[2] i     subtract 1 from both sides

x  =  ±√[2] i  - 1

So...the other two factors are    -1 + √[2] i  and   -1 - √[2] i

So...the complete factorization is

A. f(x)=(x+2)(x−(−1+i√2))(x−(−1−i√2))

x^3−4x^2+4x−16      factor by grouping

x^2 ( x - 4)  + 4 ( x - 4)   =

(x - 4) (x^2 + 4)   =

(x - 4)  ( x + 2i) ( x - 2i)

By the Remainder Theorem.....to find the remainder...just plug 3 into the function and we have

4(3)^3  - 17(3)^2  + 14(3)  - 3 = 

4*27  - 17*9  + 42  - 3  =

-6

Note that synthetic division would provide the same result

3 [  4   -17     14     -3   ]

            12    -15     -3

      4    -5     -1      -6

Let ABC be an isosceles triangle  with  AB  = AC

Draw median BM to side  AC  and  median CN to side AB

Note that  since AB  = AC...then then the medians divide  AB and AC into two equal parts.....so....MC   = NB

And since  AB  = AC, then angle ABC  = angle ACB

And BC  = BC

So...by side-angle side.....triangle  MCB is congruent to triangle NBC

So...therefore....BM  = CN

I always do very elaborate costumes but this year I'm doing something comfy and simple. I am going as a penguin. 

Probably gonna do what my little cousin is gonna do, fortnite character. I know, dreadful.

Could you tell me which concept this problem is in?

I'm a cemetery bride this year. I was catwoman last year which was pretty fun but I also looked like a spy xD
