Given f(x) = x^2 - 3x + 4

Then,f(2x + 1) = (2x+1)^2 - 3(2x+1) + 4= 4x^2 + 1 + 4x - 6x - 3 + 4= 4x^2 - 2x + 2

As per given conditionf(x) = f(2x + 1)x^2 - 3x + 4 = 4x^2 - 2x + 23x^2 + x - 2 = 03x^2 + 3x - 2x - 2 = 03x(x + 1) - 2(x + 1) = 0(3x - 2)(x + 1) = 0x = 2/3, - 1

sulldle alea Ulule toy.26. If the radil of the circular ends of a bucket 28 cm high, are 20 cm7 cm, find its capacity and total surface area.(CBSE 2011]

Answer»

Given, Height of the bucket (frustum) (h) = 45 cm

Radius 1 (R) = 28 cm

Radius 2 (r) = 7 cm

-------------------------------------------------------------------------------------------------------------

Volume of frustum = π/3 h (R²+r²+R*r) (where R is the bigger radius and r is the smaller radius and h is the height)

= π/3 45 [(28)² + (7)² + 28*7]

= π * 15 * [ 784 + 49 + 196 ]

= π * 15 * 1029

= π * 15435

= 22/7 * 15435

= 22 * 2205

= 48510 cm³

Hence our volume is 48510 cm³

Answer:

Given,

Height of the bucket (h) = 45 cm

Radius one (R) = 28 cm

Radius a pair of (r) = 7 cm

Volume of solid = π/3 h (R²+r²+R×r)

where,

R= larger radius

r = smaller radius

h= height

=> π/3 forty five [(28)² + (7)² + 28×7]

=> π × 15× [ 784 + 49 + 196 ]

=> π × 15 × 1029

=> π × 15435

=> 22/7 × 15435

=> 22× 2205

= > 48510 cm³
