Verify rolles therom the function f(x)=(x-2)(x-6)in the interval(2,6) |
|
Answer» Since, f(x=x 2+x−6 is a polynomial and every polynomial function is continuous for all x∈R So, f(x) is continuous at x∈[−3,2] Also, every polynomial function is differentiable. So, f(x) is differentiable at (−3,2) Now,f(−3)=9−3−6=0 f(2)=4+2−6=0 Hence, f(−3)=f(2)=0 Now, f′(x)=2x+1 f′(C)=2c+1 Since, all the conditions are satisfied,[tex]f′(c)=0 2c+1=0 c=−21 And, −21∈[−3,2] Hence, Rolle's theorem is verified. |

A cube painted red on two adjacent faces and black on the face opposite to the red faces and green on theremaining faces is cut into 64 smaller cubes of equal size. How many cubes are there which have no facepainted? |
|
Answer» Answer: Thus, there are two edges where the faces painted red and black meet, and each edge has FOUR cubes. Thus, there are totally 88 smaller cubes on each face. So, there are 32 smaller cubes which have at LEAST one of their faces GREEN. The remaining 64 - 32 = 32 smaller cubes have NONE of their faces green.hope it HELPS you please follow me and mark the answer as brainlist |

Let f:{1,2,3,4,5} to {1,2,3,4} be a function randomly formed. What is the probability that f is onto and f(i)≠i , i=1,2,3,4,5Answer is given 2/9Solution with explanation is required |
|
Answer» Let us first count the number of ELEMENTS in F. Total number of functions from A to B is 34=81. The number of functions which contain exactly two elements in the range is 3⋅24=48. The number of functions which contain exactly one elements in its range is 3×14=3 . THUS, the number of onto functions from A to B is 81−48+3=36 [using principle of inclusion exclusion] ∴n(F)=36 Let f∈F. We now count the number of ways in which f−1(x) consists of single ELEMENT. We can choose PREIMAGE of x in 4 ways. The remaining 3 elements can be mapped onto [y,Z] is 23−2=6 ways. ∴f−1(x) will consists of exactly one element in 4×6=24ways. Thus, the probability of the required event is 24/36=2/3. |

Sidh kare 6+√2 ak aprimy sankhaya hai |
|
Answer» Step-by-step explanation: Given, 6+√2 is irrational number, By the method of contradiction, let us assume 6+√2 is rational number, let, 6+√2 = p/q where p & q are co-primes, and b≠0, 6+√2 = p/q 6 = p/q - √2 Squaring on both sides, (6)² = (p/q - √2)² [Since (a-b)² = a² +2ab - b²] (OR) [(a-b)² = a² - b² + 2ab] 36 = (p/q)² - 2(p/q)(√2) + (√2)² 36 = p²/q² - (2p/q)(√2) + 2 (2p/q)(√2) = p²/q² + 2 - 36 (2p/q)(√2) = p²/q² - 34 √2 = (q/2q)[p²/q² - 34] Here, (q/2q)[p²/q² - 34] is rational number, So, √2 is also rational number, But it contradicts the fact that √2 is irrational number, So our assumption is wrong, 6+√2 is irrational number. |
