Answer:
coordinate will be
r = (1.33,4.33)
Explanation:
As we know that if a point will divide two given coordinates in m : n ratio
then in that case the point is given as
here we know that two points are
(-7, -4) and (3, 6)
and the ratio is given as 1 : 5
now from above formula we will have
so coordinate will be
Answer:
24.71 mm
Explanation:
Distance is proportional to focal length, so
d∝f
which means
Magnification of first lens
and
Similarly, magnification of second lens
and
From the above equations we get
and
which means,
and
So, we get
∴ Focal length should this camera's lens is 24.71 mm
