The equation showing the relationship between w and t is w = 4t

From the table, we have the following points:

(0,0) and (1,4)

Start by calculating the slope (m)

m = \frac{y_2 -y_1}{x_2 -x_1}

So, we have:

m = \frac{4 -0}{1 -0}

Simplify the numerator and the denominator

m = \frac{4}{1}

Divide 4 by 1

m = 4

The equation is then calculated as:

w = m(t - t_1) + w_1

This gives

w = 4(t - 0) + 0

Simplify

w = 4t

Hence, the equation is w = 4t

An oblique triangular pyramid has a base area
lubasha [3.4K]

The height of the oblique triangular pyramid is 18 units if the base area of 21 square units and a volume of 126 cubic units.

<h3>What is volume?</h3>

It is defined as a three-dimensional space enclosed by an object or thing.

We know the volume of an oblique triangular pyramid is given by:

\rm V = \dfrac{1}{3}b\times h

Where b is the area of the base and h is the height of the pyramid.

We have b = 21 square units  and V =  126 cubic units.

\rm 126 = \dfrac{1}{3}\times21\times h

h = 18 units

Thus, the height of the oblique triangular pyramid is 18 units if the base area of 21 square units and a volume of 126 cubic units.
