Answer» SHOW that the height of the CYLINDER of maximum volume that can be INSCRIBED in a sphere of RADIUS R is \(\large\frac{2R}{\sqrt 3}\) . A) TOOLBOX: Volume =πr2h Step 1: Radius of the sphere=R Let h be the diameter of the base of the inscribed cylinder . Then, h2+x2=(2R)2 h2+x2=4R2------(1) Volume of the cylinder =πr2h V=π(x22)2.h =πx44.h Volume=14πx2h Substituting the value of x2 we get V=14πh(4r2−h2) From (1),x2=4R2−h2 V=πR2h−14πh3

8.

A right circular cylinder is inscribed in a sphere of radius R.Show that the volume is maximum when its height is 2R/√3.

Answer»

SHOW that the height of the CYLINDER of maximum volume that can be INSCRIBED in a sphere of RADIUS R is $\large\frac{2R}{\sqrt 3}$ .

A)

TOOLBOX:

Volume =πr2h

Step 1:

Radius of the sphere=R

Let h be the diameter of the base of the inscribed cylinder .

Then,

h2+x2=(2R)2

h2+x2=4R2------(1)

Volume of the cylinder =πr2h

V=π(x22)2.h

=πx44.h

Volume=14πx2h

Substituting the value of x2 we get

V=14πh(4r2−h2)

From (1),x2=4R2−h2

V=πR2h−14πh3

Answer» Step-by-step explanation: Let the volume of cistern = V litre (L) let the flow RATE of one PIPE be x L/min and that of other pipe be y L/min Since 6 minute are needed to fill the pipe 6x+6y = V = total volume (1) V/x = TIME TAKEN by one pipe and V/y = time taken by other pipe V/x + V/y = 5 min 1/x - 1/y = 5/V (2) Solve Time taken by one pipe = 15 min and Time taken by other pipe = 10 min Option 6) 15 min and 10 min

12.

Two pipes running together can 6ll a tank in 6minutes. If one pipe takes 5 minutes more than theother to fill the tank, find the time in which eachpipe would fill the tank separately.

Answer»

Step-by-step explanation:

Let the volume of cistern = V litre (L)

let the flow RATE of one PIPE be x L/min and that of other pipe be y L/min

Since 6 minute are needed to fill the pipe

6x+6y = V = total volume (1)

V/x = TIME TAKEN by one pipe and V/y = time taken by other pipe

V/x + V/y = 5 min

1/x - 1/y = 5/V (2)

Solve

Time taken by one pipe = 15 min

and Time taken by other pipe = 10 min

Option 6) 15 min and 10 min

16.	Solve the system of linear equation by substitution.b = -3a - 7 b = a + 9 Solution: (☐, ☐)
Answer» Let's start by solving for a. TAKE the first equation, b = -3a - 7, and substitute in the second equation, b = a + 9, for b. We now have: a+ 9 = -3a - 7 Add 3a to both sides. 4a + 9 = -7 Subtract 9 from both sides. 4a = -16 Divide each side by 4. a = -4 Let's use the second equation, b = a + 9, to solve for a. Put in the value we just solved for. We now have: b = -4 + 9 Simplify. b = 5 Let's check our answer, starting with the first equation, b = -3a - 7. Put in the values for a and b. 5 = -3(-4) - 7 5 = 12 - 7 5 = 5 Do the same with the second equation, b = a + 9. 5 = -4 + 9 5 = 5 The solution to the SYSTEM of EQUATIONS is (5, -4).

16.

Solve the system of linear equation by substitution.b = -3a - 7 b = a + 9 Solution: (☐, ☐)

Answer»

Let's start by solving for a.

TAKE the first equation, b = -3a - 7, and substitute in the second equation, b = a + 9, for b.

We now have:

a+ 9 = -3a - 7

Add 3a to both sides.

4a + 9 = -7

Subtract 9 from both sides.

4a = -16

Divide each side by 4.

a = -4

Let's use the second equation, b = a + 9, to solve for a.

Put in the value we just solved for.

We now have:

b = -4 + 9

Simplify.

b = 5

Let's check our answer, starting with the first equation, b = -3a - 7.

Put in the values for a and b.

5 = -3(-4) - 7

5 = 12 - 7

5 = 5

Do the same with the second equation, b = a + 9.

5 = -4 + 9

5 = 5

The solution to the SYSTEM of EQUATIONS is (5, -4).

Answer»

Answer:

10

Step-by-step EXPLANATION:

LET the TOTAL no. of toffies be X

then, toffies given to elder son = x/3

remaining toffies = x- x/3 = 2x/3

toffies given to younger son = 1/4 × 2x/3

= x/6

still 30 toffies are left.

A/q

x/3 + x/6 + 30 = x

x - x/3 - x/6 = 30

(6x - 2x - x)/6 = 30

3x/6 = 30

x = 30 × 6/3

x = 60

total toffies = 60

toffies given to younger son = x/6 = 60/6

= 10

39.	32. Prove that root 5 is irrational
Answer» TO PROVE :- Root of 5 is IRRATIONAL PROOF We can EASILY prove this by using the cobtradiction METHOD :- Let root 5 be x/y where x and y are co-primes. $\sqrt{5} = \frac{x}{y} \\ \\ \\ \implies 5 = \frac{ {x}^{2} }{ {y}^{2} } \\ \\ \\ \implies 5 {y}^{2} = {x}^{2} \\ \\ \\ \implies {y}^{2} = \frac{ {x}^{2} }{5} \\ \\ \\ {x}^{2} is \: divisible \: by \: 5 \: so \: x \: is \: also \: divisible \: by \: 5 \\ \\ \\ now \: let \: \frac{x}{5} \: be \: s \\ \\ \\ \frac{x}{5} = s \\ \\ \\ \implies 5s = x \\ \\ \\ \implies 25 {s}^{2} = {x}^{2} \\ \\ \\ \implies 25 {s}^{2} = 5 {y}^{2} \\ \\ \\ \implies {s}^{2} = \frac{ {y}^{2} }{5} \\ \\ \\ hence \: {y}^{2} is \: divisible \: by \: 5 \: so \: y \: is \: also \: divisible \: by \: 5$ Hence both x and y are divisible by 5 so x and y aren't co-primes. Therefore it contradicts our assumption so root 5 is irrational.

We can EASILY prove this by using the cobtradiction METHOD :-

Let root 5 be x/y where x and y are co-primes.

$\sqrt{5} = \frac{x}{y} \\ \\ \\ \implies 5 = \frac{ {x}^{2} }{ {y}^{2} } \\ \\ \\ \implies 5 {y}^{2} = {x}^{2} \\ \\ \\ \implies {y}^{2} = \frac{ {x}^{2} }{5} \\ \\ \\ {x}^{2} is \: divisible \: by \: 5 \: so \: x \: is \: also \: divisible \: by \: 5 \\ \\ \\ now \: let \: \frac{x}{5} \: be \: s \\ \\ \\ \frac{x}{5} = s \\ \\ \\ \implies 5s = x \\ \\ \\ \implies 25 {s}^{2} = {x}^{2} \\ \\ \\ \implies 25 {s}^{2} = 5 {y}^{2} \\ \\ \\ \implies {s}^{2} = \frac{ {y}^{2} }{5} \\ \\ \\ hence \: {y}^{2} is \: divisible \: by \: 5 \: so \: y \: is \: also \: divisible \: by \: 5$

Hence both x and y are divisible by 5 so x and y aren't co-primes.

Therefore it contradicts our assumption so root 5 is irrational.

47.

Prove that: cos 105° + cos 15º = sin 75º - sin 15°

Answer»

ANSWER:

Step-by-step explanation:

SIN 75º - sin 15º = 2cos{(75º + 15º)/2}sin{(75º - 15º)/2}

= 2cos45ºsin30º

= 2 X (1/√2) X (1/2) = 1/√2.

COS 105º + cos 15º

= 2cos{(105º + 15º)/2}cos{(105º - 15º)/2}

= 2cos60ºcos45º

= 2 X (1/2) X (1/√2) = 1/√2.

Left-hand side = right-hand side.
