Answer:

Ans.    64 cm

Step-by-step explanation:

we have to use the ratio of actual distance and distance on projection here.

Given,

Ratio of distance in projection and actual distance is  1:200,000

That means, 1 cm in projection will be 200,000 cm in actual distance.

Here,

Actual distance is 128 km.

we know, 1 km=100,000 cm

Now,  128 km=128,00,000 cm

So, actual distance is 128 00 000 cm.

Since, 200000 cm in actual distance means 1 cm in projection.

So,

for 12800000 cm in actual distance means 12800000/200000 cm in projection.

So, in the screen distance will be-

12800000 / 200000

=64 cm

" Given f (x) = 3x + 2 and g(x) = 4 – 5x, find (f + g)(x), (f – g)(x), (f × g)(x), and (f / g)(x).1. = [3x + 2] + [4 – 5x] = 3x + 2 + 4 – 5x. = 3x – 5x + 2 + 4. = –2x + 6. (f – g)(x) 2. = f (x) – g(x)= [3x + 2] – [4 – 5x] = 3x + 2 – 4 + 5x. = 3x + 5x + 2 – 4. = 8x– 2. 3. ...= (3x + 2)(4 – 5x) = 12x + 8 – 15x2 – 10x. = –15x2 + 2x + 8. " - Google
