Which expression is equivalent to 1/√121x^9y^8z^10
sweet [91]

Answer:

1/(11 x^(9/2) y^4 z^5)

or

sqrt(x)/ 11 x^5 y^4 z^5  

Step-by-step explanation:

1/ sqrt(121x^9y^8z^10)


Lets simplify the denominator

sqrt(121x^9y^8z^10)

Break it into pieces

sqrt(121) sqrt(x^9) sqrt(y^8) sqrt(z^10)

11  sqrt (x^8) sqrt(x) y^4  z^5

11 x^4 y^4 z^5  * sqrt(x)  



Putting this back in

1

----------------------------

11 x^4 y^4 z^5  * sqrt(x)


But we dont want a sqrt root in the denominator

Multiply by sqrt(x)/sqrt(x)

sqrt(x)

----------------------------

11 x^4 y^4 z^5  * sqrt(x) sqrt(x)

sqrt(x)

----------------------------

11 x^4 y^4 z^5  * x

sqrt(x)

----------------------------

11 x^5 y^4 z^5

for a short time after a wave is created by wind the height of the wave can be modeled using y= a sin 2pit/T where a is the ampl
dangina [55]

Answer:

y = 4 sin(t/2 + 4π/3) − 2

Step-by-step explanation:

General form:

y = a sin(2π/T t)

Given a = 4 and T = 4π:

y = 4 sin(2π/(4π) t)

y = 4 sin(t/2)

Add horizontal shift of -4π/3 and vertical shift of -2:

y = 4 sin(t/2 − (-4π/3)) − 2

y = 4 sin(t/2 + 4π/3) − 2
