2.7^n+ 3.5^n-5 is divisible by 24---- to prove

put n=1

14+15-4=24

p(1) true.

put n=k

2.7^k+ 3.5^k-5=24m-------1)

to prove: n=k+1 is true

put n= k+1

2.7.7^k+3.5.5^k-5

from 1) -5=24m-2.7^k-3.5^k

14.7^k+15.5^k+24m-2.7^k-3.5^k

24m+7^k(14-2)+5^k(15-03)

24m+12.7^k+12.5^k

24(m+7^k/2+5^k/2)

24 multiplied by any digit means it is divisible by 24.

by p.m.i. it is proved that n is true for N

Given polynomials arepx³+3x²-3and2x³-5x+p

It is also given that these two polynomials leave the same remainder when divided byx-4

p(4)³+3(4)²-3 = 2(4)³-5(4)+p

64p+48-3 = 128-20+p

64p-p = 108-45

63p = 63

p = 1

Given cost of blanket is twice the number of blanketslet cost of blanket is x and number of blankets is 2xSo given total cost of blanket is ₹4608so Equation will be4608 = 2x × xx² = 2304x = √2304x = 48option (2) is correct

2304 root is 48

sorry for inconvenience check this one,Given cost of blanket is twice the number of blanketslet cost of blanket is x and number of blankets is 2xSo given total cost of blanket is ₹4608so Equation will be4608 = 2x × xx² = 2304x = √2304x = 48option (2) is correct

There are 4 Kings in a deck.(i) So the probability of drawing a king is 4/52if the card is replaced, then again the probability would be 4/52.so joint probability would be= (4/52)x(4/52)=1/169(ans)(ii) the probability of drawing a king out of 52 cards is 4/52.the probability of drawing a king out of 51 cards is (3/51)so joint probability is (4/52)x(3/51)=1/221(ans)

Surface area of solid= Surface area of Cuboid having side 7 cm + Surface area of Hemisphere having maximum diameter

= 6×(Side)² + 3 πR² where R is radius of sphere.

= 6×7² + 3×22/7×(7/2)²

= 6×49+ 3×22/7×49/4

=294 +115.50

= 409.50 cm²

If you will take diameter of hemisphere along the Diagonal of a cuboid it will just come out of surface i.e it will cross the boundary of cuboid.

Let terms of AP are a, a + d, a + 2d, a + 3d, a + 4d

Then,a*(a + 4d) = 28.... (1)

As per given condition(a + 2d) - a = 62d = 6d = 3

Put value of d in eq(1)a(a + 4*3) = 28a^2 + 12a - 28 = 0a^2 + 14a - 2a - 28 = 0a(a + 14) - 2(a - 14) = 0(a - 2)(a + 14) = 0a = 2, - 14

Thus, For a = 2, d = 3AP is 2, 5, 8, 11, 14

For a = - 14, d = 3AP is - 14, - 11, - 8, - 5, - 2

Sum of all the angles of triangle is 180°

So, 105°+57°+x = 180° 162°+x = 180° x = 180° - 162° x = 18°

tnx 👍

Last year number of bags 1720Increase in % = 20%so, 1720 of 20% = 1720×20/100 = 172×2 = 344Total bags = 1720+344 = 2064
