NARA [144]

Answer:

6000

Step-by-step explanation:

Given that :

Cost price = 4000

Find the price so that there will be a profit of 800 after allowing a discount of 20%

Selling price = (100/(100 - discount)) * 4000 + Markup)

Selling price = (100 / 80) * (4000+800)

Selling price = 1.25 * 4800

Selling price = 6000

Figure ABCD is a parallelogram.

Alika [10]

Answer:

3rd option, 44 units

Step-by-step explanation:

3x-1 = 2x+2

or, x = 3

so each side, 3×3-1 = 8

4y-2 = 2y+6

or, y = 4

so each side, 4×4-2 = 14

so perimeter

= 2(8+14)

= 44 units

Prove the identity.<br> tan^5x = tan x (sec² x - 2 sec² x + 1)

ddd [48]

goal:tan^5x=tanx(sec²x-2sec²x+1)

proof: from l.h.s to r.h.s

tan^5x=(tanx)^5=((tanx)(tan²x)(tan²x))

from trigonometry identity

(tan²x)=sec²x-1

tan^5x=(tanx(sec²x-1)(sec²x-1))

=(tanx(sec^4x-sec²x-sec²x+1))

=(tanx(sec^4x-2sec²x+1))

proved
