Answer:

Buenos días;

1) La ecuación de la velocidad en un movimiento uniformemente acelerado (M.U.A) es:

V=V₀+at.

V=30 m/s-2 m/s².t

Ahora elimina las unidades (m/s, m/s₂), y tendrás la ecuación de la velocidad en función del tiempo.  

V(t)=30-2t.

Sol: la ecuación de la velocidad en función del tiempo es : V(t)=30-2t.

2) La ecuación de la posición en función del tiempo en un M.U.A  es:

X=X₀+V₀.t+(1/2).a.t²

X=0+30 m/s.t+(1/2).(-2 m/s²).t²

Eliminas las unidades, y tendrás la ecuación de la posición en función del tiempo.

X(t)=30.t-t².

Sol: la ecuación de la posición en función del tiempo es: X(t):30t-t²

Un saludo.

Answer:

The next number selected should be between 2 and 3 .

Step-by-step explanation:

x. x    f(x)             g(x)

0        10               17

1           11              19

2          14              21

3          19              23

4         26             25

3.5      22.25        24

<u>2.5      16.25         22</u>

1.5       12.25        20

0.5       10.25       18

We see the pattern that it is increasing with only a unit. The last given data is mid of the last two values that is 3 and 4.

So the next value would be the mid of the next last two values that is 2 and 3 and will be 2.5

Now it is moving in the reverse direction in the same pattern  with a difference of a unit.

Fin the area of the polygons
german

Answer:45

Step-by-step explanation:

First, you need to calculate the area of the square.

(LxW)= 25.

Then, calculate the area of the triangle

(1/2BH)=5x(8/2)=5x4=20

Now, just add 20+25= 45

Answer:

  A) 40

  B) length = 4.275 km; not quite true. See below for explanation.

Step-by-step explanation:

A) Your calculator can tell you the ratio ...

  (national pennies)/(local pennies) = (8×10⁶)/(2×10⁵)

  = (8/2)×10⁶⁻⁵ = 4×10¹ = 40

The national drive collected 40 times as many pennies as the Valley Stream Central goal.

__

B) Multiplying the number of pennies by the diameter of each will tell the length of the line of pennies. That length can be compared to the 5 km distance to determine if the reporter's statement is true. (It is <em>not</em> true.)

  length of string = (length of penny) × (number of pennies)

  = (19×10⁻⁶ km) × (2.25×10⁵) = 42.75×10⁻¹ km = 4.275 km

The length of the pennies laid side-to-side is less than 5.0 km. The reporter's statement is not true.

_____

All scientific and graphing calculators and many 4-function calculators will let you enter numbers in scientific notation.
