The operation is known as rounding of a number.

This means basically if i measure the temperature of a city and it comes out to be 22.9 degrees. I will round it of to 30 degrees or the amount of significant figures i am designated with.

Similarly if its 22.85 and i have to round of to 3 significant figures it becomes 22.9 degrees.

ROunding off is obviously done watching to which digit we have to.

This operation is called rounding. 

For example, if I scored 97.9 points on a math test, I could round it up to 98. Or, if I scored 92.1 points, then I could round it down to 92. In both cases, the real math scores (both of which are decimals) are replaced by different, whole numbers.

The displacement (in meters) of a particle moving in a straight line is given by the equation of motion
Ksenya-84 [330]

Answer:

  • -2/a³ m/s
  • -2 m/s
  • -1/4 m/s
  • -2/27 m/s

Step-by-step explanation:

The velocity is the derivative of position:

  v = ds/dt = (d/dt)(t^-2) = -2t^-3

For t=a, the velocity is

  -2a^-3 = -2/a³ . . . . meters per second

For t=1, the velocity is ...

  -2·1³ = -2 . . . . meters per second

For t=2, the velocity is ...

  -2·2^-3 = -2/8 = -1/4 . . . . meters per second

For t=3, the velocity is ...

  -2·3^-3 = -2/27 . . . . meters per second

F(x) = 2x2 + 12x + 1<br> Determine the vertex
Gnom [1K]

Answer:

Step-by-step explanation:

The vertex would be the highest/lowest point so lets factor this first

when we factor we get

2(x^2+6x+8)

2(x+4) (x+2)

Using zero product property we find the 2 x values and x intercepts are

-4 and -2

the middle point of these points is -3

Substitute -3 for x and solve

2(-3+4) (-3+2)

2 * 1 *  -1

2*-1

-2

(-3,-2) is the vertex
