ddd [48]

Answer:

  a = 2/3

Step-by-step explanation:

A cube root is the same as a 1/3 power. The square of that gives a 2/3 power.

  a = 2/3

_____

<em>Additional comment</em>

You can see the relationship between a root index and an exponent if you consider what the root means.

Consider a cube root, for example. When you cube the root, you get the original number:

  (∛x)·(∛x)·(∛x) = x

Now, let's write the root as a power of x: x^a.

  (x^a)·(x^a)·(x^a) = x . . . . . where x^a = ∛x

We know this product is ...

  x^(a+a+a) = x^(3a) = x^1

This tells us that ...

  3a = 1   ⇒   a = 1/3

That is, ∛x = x^(1/3).

Of course an n-th root is multiplied by itself n times to get the original number, so the corresponding exponent is x^(1/n).

Slav-nsk [51]

Answer:

Option c

Step-by-step explanation:

From the question we are told that:

Four accounting majors N_a=4

Two economics majors  N_e=2

Three marketing majors  N_m=3

Total Applicants N_T=9

Generally the equation for Different ways that five of these could be hired is mathematically given by

X_5=^9P_5

X_5=\frac{9!}{(9-5)!}

X_5=15120

Generally the equation for Different ways that Three of these could be hired is mathematically given by

X_3=^9P_3

X_3=\frac{9!}{(9-5\3)!}

X_3=504 ways

Find the value of x that makes p||q
padilas [110]

Answer:

1. x = 30

2. x = 39

Step-by-step explanation:

1.

4x and ( 3x + 30 ) are alternate exterior angles,

Alternate exterior angles are equal.

4x = 3x + 30

4x - 3x = 30

x = 30

2.

x and ( 3x + 24 ) are co - interior angles.

Sum of co - interior angles is 180,

x + 3x + 24 = 180

4x + 24 = 180

4x = 180 - 24

4x = 156

x = 156 / 4

x = 39
