Answer:

<em>6.73</em> × 10^{-8}

Step-by-step explanation:

7.4 × 10^{-8}

6.7 × 10^{-9} = 0.67 × 10^{-8}

7.4 × 10^{-8} - 0.67 × 10^{-8} = ( 7.4 - 0.67 ) × 10^{-8} = <em>6.73 ×</em> 10^{-8}

Find the distance between the origin and the point R = (9,7,8). The distance is: Ensure that you use at least 4 decimal place ac
gregori [183]

Answer:

The distance between the origin and the given point is 13.9283 units.  

Step-by-step explanation:

The coordinates of origin are (0,0,0)

We are given a point R(9,7,80

The distance formula:

\sqrt{(y_1 -x_1)^2 + (y_2 -x_2)^2 + (y_3 -x_3)^2}, where (x_1, x_2, x_3) are coordinates of one point and  (y_1, y_2, y_3) are coordinates of other point.

Putting the values as:

y_1 = 9, y_2 = 7, y_3 = 8\\x_1 =0, x_2 = 0, x_3 = 0

We get d = \sqrt{81 + 64 + 49}

d = \sqrt{194}

d = 13.9283

Thus, the distance between the origin and the given point is 13.9283 units.
