Answer:
y = In | cos(2x + c ) | + c
Step-by-step explanation:
y" + (y')^2 + 4 = 0
substituting u = y'
u' + u^2 + 4 = 0
hence : u' = - (u^2 + 4 )
= 1 ------- (1)
integrating both sides of the equation 1
x + c = hence u = -2 tan(2x + c )
remember u = y'
y' = -2 tan(2x + c) ------ (2)
integrating both sides of the equation 2
y = ∫
therefore Y = In | cosu | + c
y = In | cos(2x + c ) | + c
Total amount saved in 1st case :
Total amount saved in 2nd case :
( Here are number of months )
Let, after x months the amount saved in both cases is same.
So,
Amount saved :
Hence, this is the required solution.
Answer: 150+475= Price before sale.
Step-by-step explanation:
Answer:
1344
Step-by-step explanation:
100cm = 1 m
Convert the dimensions of the floor to cm = Area of a rectangle = length x breadth = 320 x 280 = 89,600m²
Area of a square = length² = 10cm² = 100cm²
Number of tiles that would be needed = area of floor / area of square
89,600cm² / 100cm² = 896
Cost of one tile = rs 150 / 100 = 1.5
Cost of 896 tiles = 1.5 x 896 = 1344
Answer:√(6/5) and √(9/7) and √(7/5)
Step-by-step explanation:
1/4 = 0.25
5/4 = 1.25
√(6/5)=1.095445...
√(9/7)=1.1338934...
√(7/5)=1.1832159...
Thus, any non-perfect square radicals will be irrational numbers.
Hope this helps!! :)
