Answer:

  \textbf{A. }\quad\dfrac{b^4}{a}

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)/(a^c) = a^(b-c)

  a^-b = 1/a^b

___

The expression can be rewritten as ...

  \dfrac{a^3b^5}{a^4b}=a^{3-4}b^{5-1}=a^{-1}b^4\\\\=\boxed{\dfrac{b^4}{a}}

What is the length of a kite string that is 6 meters above and 9 meters away from where it is being held? Round to the nearest t
ivann1987 [24]

Answer:

10.8 meters

Step-by-step explanation:

This situation forms a right triangle, where the length of the kite string is the hypotenuse, the distance from where it is held is the long leg, and the height is the short leg.

Use the pythagorean theorem to solve for c, the length of the kite string.

a² + b² = c²

6² + 9² = c²

36 + 81 = c²

117 = c²

10.8 = c

So, the length of the kite string is 10.8 meters

Describe how the graph of y=|x| – 4 is like the graph of y= |x| – 4 and how it is different.
Molodets [167]
If we were to subsitute the points and graph the equation we would notice that the shape is the same for both: a 45 degree angle line that goes upleft and up right
the graph of y=|x| looks like a right angle corner that is facing up that is ballancing on the point (0,0)
the graph of y=|x|-4 is the same except that the graph is shifter 4 units to the right ie. the point ofo the graph/rightangle is on point (4,0)
