To compare the volumes of the prism we used the scale factor:

volume scale factor=(linear scale factor)³

the linear scale factor of the prism is:

(length of larger prism)/(length of smaller prism)

=36/9

=4

thus the volume scale factor will be:

4³=64

hence the volume of the larger prism is 4 times that of the smaller prism.

In the given expression

To differentiate it with respect to it, we will writ y' for every term of y

The differentiation of

The differentiation of

The differentiation of

Now let us write all of them in one line

Put the terms of y' on one side and the other term on the other side

Take y' as a common factor

Divide both sides by the bracket

Since the given point is (-2, 1), then

x = -2 and y = 1

Substitute them to find y'

**The value of y' is -16/19**

It may be useful because sometimes ur estimations and when u get your answer half of the time it's very close to it or a number less or a number higher
