A hotel purchase 48 beds 35 chairs and 25 tables. If each bed cost Rs. 1350 each chair costs Rs. 225 each table costs Rs. 375. Find the total amount of bill ?

Answer»

ANSWER:

Rs. 82050

Step-by-step explanation:

ONE BED COSTS= Rs. 1350

THEN THE COST OF 48 BEDS WILL BE Rs. 1350 * 48 = Rs. 64800

ONE CHAIR COSTS = Rs. 225

35 CHAIRS COST WILL BE Rs. 225 *35 = Rs. 7875

ONE TABLE COSTS = Rs. 375

25 TABLES COST WILL BE = Rs. 25 * 375 = Rs. 9375

TOTAL COST = Rs. 64800 + 7875 + 9375 = Rs. 82050

5.

Can the sum of n terms in an A. P. Is n square +13n .justify your answer

Answer»

YES , sum of n terms of an AP would be n² + 13nwhose FIRST term is 14 and COMMON difference is 2.we have to check sum of n terms in an AP would be n² + 13N or not .let's try to resolve it in standard form of FORMULA of sum of n terms.i.e.,

Sn = n/2[2a + (n - 1)d ] .......(1)

n² + 13n = n(n + 13)= n/2 (2n + 26)= n/2 [2n - 2 + 28 ]= n/2 [ 2(n - 1) + 2 × 14 ]= n/2 [2(14) + (n - 1)2 ]........(2)

on comparing equations (1) and (2) we see a = 14 and d = 2 {a and d are both integers }hence sum of n terms of an AP would be n² + 13nwhose first term is 14 and common difference is 2.

18.

Solve it...........

Answer»

ANSWER:

VALUE of P(y) at y = 0 is 3.

GIVEN:

P(y) = 5y-4y²+3

TO FIND:

Value of above EXPRESSION at y = 0.

SOLUTION:

=> P(y) = 5y-4y²+3

Finding P(y) at y = 0.

=> P(0) = 5(0)-4(0)²+3

=> P(0) = 0-0+3

=> P(0) = 3

Value of P(y) at y = 0 is 3.

NOTE:

Some IMPORTANT formulas:

(a+b)(a-b) = a²-b²

(a+b)³ = a³+b³+3ab(a+b)

(a-b)³ = a³-b³-3ab(a-b)

a³+b³ = (a+b)(a²+b²-ab)

a³-b³ = (a-b)(a²+b²+ab)

(a+b)² = (a-b)²+4ab

(a-b)² = (a+b)²-4ab

Sum of ROOTS=2+(-1/3)=6-1/3=5/3

Product of roots=(2)(-1/3)=(-2/3)

x²-(Sum of Roots)x +(Product of Roots)=0

x²-(5/3)x-2/3=0

Step-by-step EXPLANATION:

x = 3 + 2root2

then 1/x= 1/3+2root2

=3 - 2root2/9-8= 3-2root2

and we know that (x+1/x)"2=x^2 + 1/x^2 +2

44.	Find the maximum and minimum value of f(x)= sinx+root 3 cosx
Answer» GIVEN, $\longrightarrow\sf{f(x)=\sin x+\sqrt3\,\cos x}$ DIVIDING and multiplying 2 on RHS, $\longrightarrow\sf{f(x)=2\left[\dfrac{\sin x+\sqrt3\,\cos x}{2}\right]}$ $\longrightarrow\sf{f(x)=2\left[\dfrac{1}{2}\,\sin x+\dfrac{\sqrt3}{2}\,\cos x\right]}$ $\longrightarrow\sf{f(x)=2\left[\cos60^o\sin x+\sin60^o\cos x\right]}$ $\longrightarrow\sf{f(x)=2\left[\sin x\cos60^o+\cos x\sin60^o\right]}$ SINCE $\sf{\sin A\cos B+\cos A\sin B=\sin(A+B),}$ $\longrightarrow\sf{f(x)=2\sin(x+60^o)}$ Well, since $\sf{\sin x\in[-1,\ 1],}$ $\longrightarrow\sf{\sin(x+60^o)\in[-1,\ 1]}$ $\longrightarrow\sf{2\sin(x+60^o)\in[-2,\ 2]}$ That is, $\longrightarrow\sf{f(x)\in[-2,\ 2]}$ Hence, $\longrightarrow\sf{\underline{\underline{\min(f(x))=-2}}}$ $\longrightarrow\sf{\underline{\underline{\max(f(x))=2}}}$

Find the maximum and minimum value of f(x)= sinx+root 3 cosx

Answer»

GIVEN,

$\longrightarrow\sf{f(x)=\sin x+\sqrt3\,\cos x}$

DIVIDING and multiplying 2 on RHS,

$\longrightarrow\sf{f(x)=2\left[\dfrac{\sin x+\sqrt3\,\cos x}{2}\right]}$

$\longrightarrow\sf{f(x)=2\left[\dfrac{1}{2}\,\sin x+\dfrac{\sqrt3}{2}\,\cos x\right]}$

$\longrightarrow\sf{f(x)=2\left[\cos60^o\sin x+\sin60^o\cos x\right]}$

$\longrightarrow\sf{f(x)=2\left[\sin x\cos60^o+\cos x\sin60^o\right]}$

SINCE $\sf{\sin A\cos B+\cos A\sin B=\sin(A+B),}$

$\longrightarrow\sf{f(x)=2\sin(x+60^o)}$

Well, since $\sf{\sin x\in[-1,\ 1],}$

$\longrightarrow\sf{\sin(x+60^o)\in[-1,\ 1]}$

$\longrightarrow\sf{2\sin(x+60^o)\in[-2,\ 2]}$

That is,

$\longrightarrow\sf{f(x)\in[-2,\ 2]}$

Hence,

$\longrightarrow\sf{\underline{\underline{\min(f(x))=-2}}}$

$\longrightarrow\sf{\underline{\underline{\max(f(x))=2}}}$
