Answer:

$\frac{108x^8}{y^5}$

Step-by-step explanation:

$(\frac{3x^2}{y} )^3 * (\frac{2x}{y})^2=\frac{3^3x^6}{y^3} *\frac{2^2x^2}{y^2} =\\= \frac{108x^8}{y^5}$

The perimeter of a college basketball court is 96m and the length is 14me more than the width. what are the dimesions?

Margaret [11]

Step-by-step explanation:

let width =x

length=x+14

....

perimeter=96=2*(L+W)

96=2*(X+X+14)

96=4x+28

96-28=4x

68=4x

68/4=x

17=x the width

length = 17+14=31m

....

Check

17+17+31+31=96

Solve for X. Greatly appreciate if someone could answer soon:)

vampirchik [111]

X = 11
angle LKM = angle KLM = angle LMK because it is an equilateral triangle
180/3 = 60
60=3x-27
60-27=3x
33=3x
x=11

A radioactive compound with mass of 260 grams decays at a rate of 3.8% per hour. Which equation represents how many grams of the

Dahasolnce [82]

The exponential equation that represents how many grams of the compound will remain after 8 hours is:

B: C=260(0.962)^8

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

A radioactive compound with mass of 260 grams decays at a rate of 3.8% per hour, hence the equation for the mass after t hours is given by:

$A(t) = 260(1 - 0.038)^t$

$A(t) = 260(0.962)^t$

After 8 hours, the amount is given by:

$A(t) = 260(0.962)^8$

Hence option B is correct.
