You are given a distance of 20 kilometers and time of 30 minutes. You are required to find for the speed of the travelling object. The equation for speed is distance over time. Speed is a scalar quantity. It tells you the direction of the travelling object. The solution in this problem is,

Speed = distance/time
Speed = 20 kilometers / 30 minutes
<u>Speed = 2/3 kilometers per minute or 0.667 kilometers per minute</u>
<span>Therefore, the speed of the object is 0.667 km per minute.</span>

Which statement about the point (2, 0) is true?

ICE Princess25 [194]

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

The Correct choice is : C

$\qquad \sf \dashrightarrow \: it \: \: is \: \: on \: \: the \: x - axis$

As we can observe, the y - coordinate ( ordinate ) of the given point (2 , 0) is 0. so it's obvious that it's distance from x - axis is Zero. In other words we can say that the point is lying on x - axis.

Whats the distance between (-8,-7) (8,-4)

balandron [24]

To find the distance between points, use the distance formula.

Distance formula: $\sqrt{ (x_{2} - x_{1})^{2} + ( y_{2} - y_{1})^{2} }$

Plug in your values for $x_{2}, x_{1}, y_{2}, y_{1}$ using (-8, -7) and (8, -4) and solve.

$\sqrt{(8 - (-8))^{2}+(-4 - (-7))^{2}}$
$\sqrt{(8+8)^{2}+(-4+7)^{2}}$
$\sqrt{(16)^{2}+(3)^{2}}$
$\sqrt{256+9}$
$\sqrt{265}$ ≈ $16.28$

Answer:
Approximately 16.28 units.
