Answer:

<h2>g > 0</h2>

Step-by-step explanation:

Among the options, the most reasonable is g > 0, because the movement of a pendulum depends on gravity, it's the reason of the movement actually, because the gravity is the acceleration of such oscillation.

Moreover, without gravity there weren't any pendulum movement, remember that acceleration refers to the change of velocity, which is what happens in all oscillations of a pendulum. If you think about it, you will realize that a pendulum stops in extreme points, then goes back, this movement tend to be periodical, because the gravity is approximately constant basically.

Therefore the right answer is g > 0.

Three-fourths of the employees at a bookstore came to a staff meeting. Less than 24 employees were at the meeting. The inequalit
Len [333]

Answer:

The correct option is 4.

Step-by-step explanation:

It is given that the three-fourths of the employees at a bookstore came to a staff meeting. Less than 24 employees were at the meeting.

Let the total number employees be e.

Three fourth of the total employees is \frac{3}{4}e, the total number of employees at the meeting were less than 24.

\frac{3}{4}e

Multiply 4 both sides.

\frac{3}{4}e\times 4

3e

Divide both sides by 3.

e

Therefore the value of e is less than 32.

In a number line as we approach towards left the the value of integers decreases.

Since the value of e is less than 32, therefore the solution graph is from negative infinity to 32.

Since 32 is not included in the solution set, therefore there is an open circle on 32.

Option 4 is correct.

Is UVW=Xyz?if so, name the postulate that applies
aivan3 [116]

By critically observing the two triangles, we can deduce that they: B. might not be congruent.

<h3>The properties of similar triangles.</h3>

In Geometry, two triangles are said to be similar when the ratio of their corresponding sides are equal in magnitude and their corresponding angles are congruent.

By critically observing the two triangles, we can logically deduce that the three angles of both triangles are congruent in accordance with AAA similarity postulate:

  • <U ≅ <X
  • <V ≅ <Y
  • <W ≅ <Z

However, AAA isn't a congruence postulate and as such all similar triangles might not be congruent.
