Answer:

FALSE

Step-by-step explanation:

In order to be consistent with the system of unit we should decide if we are going to work with the CGS system <em>(centimeter-gram-second)</em> or the MKS system <em>(meter-kilogram-second). </em>

If we decide to work with the CGS system, the equation of motion would be

8,000x ′′ + 2x = 0; x(0) = 3, x ′ (0) = 0

since 1 Kg = 1,000 g

If we decide to work with the MKS system, the equation of motion would be

8x ′′ + 2x = 0; x(0) = 0.03, x ′ (0) = 0

given that 1 mt = 100 cm

Fibonacci numbers can be found in many places in nature, for example, the number of petals in a daisy, the number of spirals in
Otrada [13]

Answer: The Fibonacci sequence is a numerical pattern that can appear in many living things. It was first described in the 12th century by the Italian Leonardo Finonacci.

It is an infinite sequence that begins with 0 and 1. The sequence is completed with the sum of the previous 2 numbers.

Following this logic, we can assemble the sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144 and so on.

This sequence is very common in nature and can be observed in many living things, such as insects, plants, the human face, even a chameleon's tail.

For example in a shell.

If a to the power x by y is equal to 1 then the value of x is​
Mazyrski [523]

Answer:

a^x/y=1              x: 0

Step-by-step explanation: w.k.t,        a^0=1( any variable raised to 0 is 1)

                                    so, here the exponent is x/y which should have been 0 so that answer was 1.

What equation represents a parabola that opens UP with the vertex at 2,4
lubasha [3.4K]

Answer:

  y = (x -2)^2 +4

Step-by-step explanation:

The vertex form of the equation of a parabola is ...

  y = a(x -h)^2 +k

for vertex (h, k) and vertical scale factor "a". When a > 0, the parabola opens upward.

One equation for your parabola could be ...

  y = (x -2)^2 +4

__

In standard form this one is ...

  y = x^2 -4x +8
