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.

What is the solution to the system of equations?
sukhopar [10]

Answer:

(x, y) = (-3, -6)

Step-by-step explanation:

The second equation can be used to write an expression for y:

... -5x -21 = y . . . . . . . add y-21 to both sides

This expression can be substituted for y in the first equation:

... 6 = -4x +(-5x -21)

... 27 = -9x . . . . . add 21, collect terms

... -3 = x . . . . . . . divide by -9

Using this value of x in the expression for y, we find ...

... -5(-3) -21 = y = -6

The solution is x = -3, y = -6.

katovenus [111]

Good evening

Answer:

A) 6

Step-by-step explanation:

Firstly, the solution set to the inequality is : x > 7

Because, x + 8 > 15 ⇌ x > 15 - 8 ⇌ x > 7

Hence

The only number that is NOT in the solution set is 6

What is the following product? sqr root 10 x sqr root 10
DENIUS [597]

Answer:

10

Step-by-step explanation:

Note that \sqrt{a} × \sqrt{a} = a

Consider the following example

\sqrt{100} × \sqrt{100}

= 10 × 10

= 100 ← the value inside the radical, thus

\sqrt{10} × \sqrt{10} = 10
