Martin wants to use coordinate geometry to prove that the opposite sides of

romanna [79]

The correct answer is option A which is the distance between A and D will be AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$ .

<h3>What is coordinate geometry?</h3>

A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

The formula utilised to find the distance between two points is;-

X = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

We have the coordinates of the point A = (0, 0) and D is (0, b).By applying the formula to find the distance between A and D.

AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$ .

Therefore the correct answer is option A which is the distance between A and D will be AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$ .

Calcula el volumen en metros cúbicos de una piscina que tiene 8 m de largo 2 m de ancho y 1.5 m de profundidad

Stella [2.4K]

Answer:

V = 24 m³

Step-by-step explanation:

The given question says that, 'Calculate the volume in cubic meters of a pool that is 8 m long, 2 m wide and 1.5 m deep'.

A pool is in the shape of a cubiod. The volume of the cuboid is given by :

V = lbh

Where

l is length, b is width and h is height

Put all the values,

V = 8 × 2 × 1.5

= 24 m³

So, the volume of the pool is equal to 24 m³.
