An automobile license plate number issued by a certain state has 6 character positions. Each of the first 3 positions contains a single digit from 0 through 9. Each of the last 3 positions contains 1 of the 26 letters of the alphabet. Digits and letters of the alphabet can such license plate number can be made?

From the top of a tower two bodies are projected with the same intital speed of 40 ms^(-1) ,first body vertically upwards and second body vertically downwards .A third body is freely released from the top of the tower.If their respective times of flights are T_(1),T_(2) and T_(3) Identify the correct descending order of the times of flights

Integral of the form int[xf\'(x)+f(x)]dx can be evaluated by using integration by parts in first integral and leaving second integral as it is.Now answer the question: int[1/(x^4+1)-(4x^4)/(x^4+1)^2]dx= (A) x^2/(x^4+1)+c (B) x^3/(x^4+1)+c (C) x/(x^4+1)+c (D) none of these

Integral of the form int[xf\'(x)+f(x)]dx can be evaluated by using integration by parts in first integral and leaving second integral as it is.Now answer the question: int[x^(x+1)(logx+1)+x^x]dx= (A) x^(x+2)+c (B) x^(x+1)+c (C) x^x+x+c (D) none of these

Integral of the form int[xf\'(x)+f(x)]dx can be evaluated by using integration by parts in first integral and leaving second integral as it is.Now answer the question: int(x+sinx)/(1+cosx)dx= (A) xtanx/2+c (B) x/2tanx/2+c (C) x/2tanx+c (D) none of these

A body is thrown up in a lift with a velocity 5ms^(-1) relative to the lift and the time of flight is found to be 0.8 s. The acceleration with which the lift is moving up is (g=10ms^(-2))

If it possible to form a word with 1^(st) 4^(th) 7^(th) and 11^(th) letters of the word 'SUPERFLUOUS', write the first letter of that word. Otherwise, X is the answer

The postal rate for first-class mail is 44 cents for the first ounce or portion thereof and 17 cents for each additional ounce or portion thereof up to 3.5 ounces. The cost of a 3.5-ounce letter is 95cancel c . A formula for the cost in cents of first-class postage for a letter weighing N ounces (N le 3.5) is

An explosion blows a rock into three parts. Two parts go off at right angles to each other . These two are 1 kg first part moving with a velocity of 12 ms^(-1) and 2 kg second part moving with a velocity of 8 ms^(-1) . If the third part flies off with a velocity of 4 ms^(-1) . Its mass would be
