Frequency  = 1 / period

So

Period = 1 /Frequency =  1 / 659

We have the form

y = A sin (B x)

A = the amplitude = 2.5

B =  [ 2pi ] / period  =   2pi / (1/659)   =   1318 pi

So....as the guest found....the function is

y = 2.5sin (1318 pi * x )

(3/4)^(5/6)    or     [(3/4)^(1/6) ]^5

You forgot to include the sin function...

2.5 sin (1318 pi x)

7x-3y+5=16   ⇒  7x - 3y  = 11       (1)

4y=3x+17   ⇒     -3x + 4y  = 17     (2)

Multiply the first equation through by 4  and the second through by 3....and we have

28x -12y  = 44

-9x + 12y  = 51       add these

19x  = 95     divide both sides by  19

x = 5

And using (1)  we can find y 

7(5) - 3y = 11

35 - 3y = 11        add 3y to both sides and subtract 11 from both sides

24 = 3y      divide both sides by 3

8 = y

So

(x , y) = ( 5, 8)

Good job, EW!!!

[ I didn't know this, either....until I looked it up...!!!  ]

I feel sorry for you

32^(4/5)   =

[ 32^(1/5) ]^4  =

[ ⁵√32 ]^4  =

[ 2 ]^ 4  =

If you decline cookies....you don't get milk....

A. magnitude

360  

36 * 10

(9 * 4) * (5 * 2)

3^2 * 2^2 * 5  * 2

3^2 * 2^3 * 5

So....the prime factors are  2, 3 and 5    !!!

I'm  assuming that you mean the base length is 64 feet

We can use the tangent inverse to find the angle of elevation....this is given by

arctan (height / half of base length)  =  angle of elevation

arctan (350 / 32) = angle of elevation ≈  84.7°

The angle of depression =  angle of elevation

I don't go to bed till 9:30 or later

so true today is one of those days where i just want to sleep. whats worse is im gonna be at school till 9 pm tonight.................

B and C

10 = 5(x - 3)     divide both sides by 5

2 = x - 3    add 3 to both sides

5 = x

We need the formula for the area of a circle....it is  3.14 * radius^2

A - The diameter is 6in....so...the radius is 3in

Total area for 10 pancakes =  10 * 3.14 * 3^2  =  282.6 in ^2

B -   25 * 3.14 * 2^2  =  314 in ^2

C  =  circumference of a circle = 2 (3.14) * radius

So

6.28 = 2 (3.14) ( radius)

6.28 = 6.28 ( radius)    divide both sides by 6.28

1 = radius

So....total area =   50 * 3.14 * 1^2  =  157 in ^2

So...the rankings from best to worst based on the area   =  B  A   C

ok 

thats ok i just dont know the work the answer i know

im sorry i tried

that is wrong it says 5
