Question

Algebraic expression as a product of two factors such that one factor is the HCF of the terms of the expression 12pq-+30q

Answer 1

Step-by-step explanation:

To find : Magnification of the image.

Solution :

Given that,

Height of object is 3 cm.

Height of image is 6 cm.

In front of a concave mirror.

We know,

Magnification produced by a mirror is equal to the ratio of the height of the image to the height of the object.

Mathematically,

• m = h'/h

[Where, h' is height of image and h is height of object]

Put h' and h in formula :

\implies⟹ m = 6/3

\implies⟹ m = 2

Therefore,

Magnification is +2.
