Each washing machine is $390 and the first washing machine is better because its marked down all the way in stead of a discount, meaning that the tax will be lower (I think)
Answer:20000
Step-by-step explanation:
(1-sin(x))(1+sin(x))=1/1+tan(x^2)
I think the right side is tan^2 x ( the square of tan x)
Left side = 1 - sin^2 x
Right side = 1 / ( 1 + (sin^2 x / cos^2x))
= 1 / (cos^2x + sin^2x) / cos^2 x
Now sin^2 x + cos^2 x = 1 so
this = 1 / 1 / cos^2x
= cos^2x = 1 - sin^2 x = Left side - Proved
Answer:
11ts + 4t^2 + 7t
Step-by-step explanation:
7st + 4t(s + t + 4) - 9t
= 7st + 4ts + 4t^2 + 16t - 9t
= 11ts + 4t^2 + 7t
Answer:
a. 25.12 cm^2
Step-by-step explanation:
Area = π * r^2
a = π * 4^2
a = π * 8
a = 25.12
