§in 75°+sin15°= 3 . |
|
Answer» (Sin75+Sin15). We will expand it by using the Identity: Sina+Sinb=2 sin(a+b)/2•cos(a-b)/2. Hence, we get Sin75+Sin15 = 2•sin(75+15)/2•cos(75–15)/2 = 2•sin45•cos30 = 2×1/√2×√3/2 =√3/√2*√2/√2=√6/2 |

Two dice are thrown at the same time and the product of numbers appearing on them isnoted. Find the probability that the product is a prime number |
|
Answer» GIven that two dice are rolled. Then the probability of outcomes n(S) = 6 * 6 = 36. Let E be the event of getting a product less than 9. The number whose product is less than 9 = ,{1,2},{1,3},{1,5},{2,1},}{3,1},,{5,1}, = 6 Therefore the required probability P(E) = n(E)/n(S) = 6/36 = 1/6 |

|
Answer» The third term of a GP = square of its firsttermar^2 = (a)^2r^2 = a^2÷ar^2 = a .......(1)now it is given that 5th term is 64 so ar^4 = 64a(r^2)^2 = 64from eq (1)a(a)^2 = 64a^3 = 64a = 4now from eq (1) r^2 = a r = a^(1/2)r. = 4^(1/2)r. = 2now we have a and r so we can calculate the first six terms of the GP.The first six terms if the GP are a, ar, ar^2, ar^3, ar^4, ar^5now putting the value if a and r we have first six terms of the GPSo the terms are 4, 8, 16, 32, 64, 128 |
