Simplify the expression.

Sati [7]

Answer:

LAST OPTION: $x^9$

Step-by-step explanation:

For this exercise it is important to remember the Power of a power property, which states that:

$(a^m)^n=a^{mn}$

The expression given in the exercise is:

$(x^\frac{3}{2})^6$

Therefore, in order to simplify it, you must apply the Power of a power property explained before.

Then, you get the following expression:

$=x^{(\frac{3}{2}*6)}=x^{(\frac{3*6}{2})}=x^{\frac{18}{2}}=x^9$

As you can notice, the expression obtained matches with the expression provided in the last option.

Read this description of the life cycle of a mushroom. 1. A mushroom begins to grow underground as a single-celled "spore.” 2. T

Dahasolnce [82]

The correct answer is C. The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground.

Explanation:

Two key features of living organisms are energy processing and response to stimuli. These two features imply organisms require nutrients, which can be taken from the environment or created through a process such as photosynthesis and they sense their surroundings and respond to it.

Moreover, these two features are exemplified by mushroom (fungi) in the sentence "The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground" because the first section shows the developing mushroom takes nutrients from the soil or its environment and this is essential for growing and survival. Also, the second section of the sentence shows the developing mushroom can sense its environment and respond by developing only in appropriate conditions.

A right cylinder has a height of 20 1/2ft and a diameter of 1 1/5 times it's height what is the volume of the cylinder? Use 3.14

anygoal [31]

Volume (V) of a cylinder is the area of circular base (pi×r^2) times it's length/height (h):
$V = \pi {r}^{2} (h) \: \: \pi = 3.14$
h = 20.5 ft
diameter (d) = 1 1/5 × h, 1 1/5 = 6/5 = 1.20
d = 1.20 × 20.5 = 24.6 ft
radius (r) = 1/2 d = 24.6/2 = 12.3 ft
$V = \pi {r}^{2} (h) \\ V = 3.14 ({12.3}^{2}) (20.5) \\ V = 3.14 (151.29) (20.5) \\ V = 475.05 (20.5) = 9738.54 \: {ft}^{3}$
