If f:R→R, g :R→R are defined by f(x) = 3x-1, g(x) =x²+1 then find 1. gof(2a-3) 2. fog(2) |
|
Answer» Answer F(x)=3x−4 ⇒f −1 (x)= x+4
; g(x)=2+3x ⇒g −1 (x)= 3 x−2
f −1 (5)= 3 5+4
=3 (g −1 of −1 )(5)=g −1 [f −1 (5)]=g −1 (3) = 3 3−2

Please log in or register to answer this question. 1 Answer 0 votes answered Nov 7, 2017 by akansha Expert (2.2k points) LET four numbers in A.P. be a – 3d, a – d, a + d and a + 3d. (a – 3d) + (a – d) + (a + d) + (a + 3d) = 32 ⇒ 4a = 32 ⇒ a = 8 Product of extremes = (a – 3d) (a + d) + (8 – 3d) (8 + 3d) = 64 – 9d2 Product of means = (a – d) (a + d) = (8 – d) (8 + d) = 64 – d2 Product of extremes: product of means = 7:15 (Given) When a = 8 and d = 2 a – 3d = 8 – 3 × 2 = 8 – 6 = 2 a – d = 8 – 2 = 6 a + d = 8 + 2 = 10 a + 3d = 8 + 3 × 2 = 8 + 6 = 14 When a = 8, d = –2 a – 3d = 8 – 3 × (–2) = 8 + 6 = 14 a – d = 8 – (–2) = 8 + 2 = 10 a + d = 8 – 2 = 6 a + 3d = 8 + 3 × (–2) = 8 – 6 = 2 ∴ The four numbers are 2, 6, 10 and 14 |

) A picture is to be painted on a canvas of length 40 cm and width 80 cm. A margin of 5 cm has to be left on all sides of the canvas. Find the area of the actual picture and the area of the margin in sq m |
Answer»
⠀ Given,
⠀ We are said that a picture is painted on a canvas whose length = 40 cm, and breadth = 80 cm. And there is a margin of 5 cm from all sides along the canvas. ⠀ We've to find the area of actual picture (excluding Margin) and the area occupied by margin in SQUARE m. So, let's find the area of whole canvas first by inserting the given values in the Formula of Area of Rectangle. Thus, the area of canvas (ABCD) is 3200 cm². ⠀
According to question, the canvas has a margin of 5 cm along it's side. So, subtract 5 cm from all four sides of ABCD, to get the dimensions of PQRS. Find area in sq. m. (Refer to the attachment for better understanding). RS = length = 40cm - (5cm + 5cm) = 30cm
QS = Breadth = 80cm - (5cm + 5cm) = 70 cm Put the obtained values in the Formula, ⠀
⠀ Now, To Find the area of margin, subract PQRS from ABCD. ⠀
