2.	Log sin 1 . log sin 2 . log sin 3 .............log sin 179
Answer» Answer: 0 Step-by-step explanation: The given expression is $\log \sin 1\cdot \log \sin 2\cdot \log \sin 3\cdot...\cdot\log \sin 179$ We NEED to find the VALUE of given expression. From the given expression it is clear that $\log \sin 90$ TERM of LIES in the expression. We know that $\sin 90^{\circ}=1$ $\log(1)=0$ Using this facts, we get $\log \sin 90=\log (1)=0$ If any NUMBER multiplied by 0, then the resultant value is 0. $\log \sin 1\cdot \log \sin 2\cdot \log \sin 3\cdot...\cdot \log \sin 90\cdot...\cdot\log \sin 179$ $\log \sin 1\cdot \log \sin 2\cdot \log \sin 3\cdot...\cdot (0) \cdot...\cdot\log \sin 179$ $0$ Therefore, the value of given expression is 0.

2.

Log sin 1 . log sin 2 . log sin 3 .............log sin 179

Answer»

Answer:

0

Step-by-step explanation:

The given expression is

$\log \sin 1\cdot \log \sin 2\cdot \log \sin 3\cdot...\cdot\log \sin 179$

We NEED to find the VALUE of given expression.

From the given expression it is clear that $\log \sin 90$ TERM of LIES in the expression.

We know that

$\sin 90^{\circ}=1$

$\log(1)=0$

Using this facts, we get

$\log \sin 90=\log (1)=0$

If any NUMBER multiplied by 0, then the resultant value is 0.

$\log \sin 1\cdot \log \sin 2\cdot \log \sin 3\cdot...\cdot \log \sin 90\cdot...\cdot\log \sin 179$

$\log \sin 1\cdot \log \sin 2\cdot \log \sin 3\cdot...\cdot (0) \cdot...\cdot\log \sin 179$

$0$

Therefore, the value of given expression is 0.

Answer» SOLUTION GIVEN Population of a village in year 2007 was 180000 it became 210000 in 2008 TO DETERMINE The per cent rise in population from 2007 to 2008 CONCEPT TO BE IMPLEMENTED Percentage In study mathematics the term percentage is used. It is DENOTED by the symbol % The percentage is a number or ratio which is expressed as a fraction of 100. PROCESS In order to calculate percentage we divide the number by whole and multiply by 100 EVALUATION Here it is given that Population of a village in year 2007 was 180000 it became 210000 in 2008 So increase in population from 2007 to 2008 = 210000 - 180000 = 30000 So the required per cent rise in population from 2007 to 2008 $\displaystyle \sf{ = \frac{30000}{180000} \times 100 \: \%}$ $\displaystyle \sf{ = \frac{1}{6} \times 100 \: \%}$ $\displaystyle \sf{ = \frac{100}{6} \: \%}$ $\displaystyle \sf{ = \frac{50}{3} \: \%}$ $\displaystyle \sf{ = 16 \frac{2}{3} \: \%}$ ━━━━━━━━━━━━━━━━ Learn more from Brainly :- 1.

If Population of a village in year 2007 was 180000 it became 210000 in 2008, What was the per cent rise in population from 2007 to 2008?

Answer»

SOLUTION

GIVEN

Population of a village in year 2007 was 180000 it became 210000 in 2008

TO DETERMINE

The per cent rise in population from 2007 to 2008

CONCEPT TO BE IMPLEMENTED

Percentage

In study mathematics the term percentage is used. It is DENOTED by the symbol %

The percentage is a number or ratio which is expressed as a fraction of 100.

PROCESS

In order to calculate percentage we divide the number by whole and multiply by 100

EVALUATION

Here it is given that Population of a village in year 2007 was 180000 it became 210000 in 2008

So increase in population from 2007 to 2008

= 210000 - 180000

= 30000

So the required per cent rise in population from 2007 to 2008

$\displaystyle \sf{ = \frac{30000}{180000} \times 100 \: \%}$

$\displaystyle \sf{ = \frac{1}{6} \times 100 \: \%}$

$\displaystyle \sf{ = \frac{100}{6} \: \%}$

$\displaystyle \sf{ = \frac{50}{3} \: \%}$

$\displaystyle \sf{ = 16 \frac{2}{3} \: \%}$

25.	prove that - 4 is less than or equal to cos 2 X + 3 sin x is less than or equal to 17 / 8 for all real x
Answer» If you know derivatives then this question can be SOLVED pretty easily. DIFFERENTIATE the y = cos2x + 3sinx function with RESPECT to x. Then by dy/dx=0 you'll GET some values of x. Differentiate again to get d²y/dx². SUBSTITUTE values of x (which you had obtained by dy/dx=0) in this function of d²y/dx². For d²y/dx² < 0 you'll get maximum value of function. For d²y/dx² > 0 you'll get minimum value of function. Godspeed!

45.	Divide 24 in three parts such that they are in AP and their product is 440.
Answer» First part = x Second part = x+d Third part = x+2d The two equations are x + (x+d) + (x+2d) = 24 and x(x+d)(x+2d) = 440 Simplifying the first equation: x + (x+d) + (x+2d) = 24 x + x + d + x + 2d = 24 3x + 3D = 24 x + d = 8 d = 8-x SUBSTITUTING in the second equation: x(x+d)(x+2d) = 440 x(x+8-x)[x+2(8-x)] = 440 x(8)[x+16-2x] = 440 8x(16-x) = 440 x(16-x) = 55 16x-x² = 55 -x²+16x-55 = 0 x²-16x+55 = 0 (x-11)(x-5) = 0 x-11 = 0 ; x-5 = 0 x = 11; x = 5 d = 8-x d = 8-x d = 8-11 d = 8-5. ; d = 3 ONE solution: First part = x = 11 Second part = x+d = 11+(-3) = 8 Third part = x+2d = 11+2(-3) = 11-6 = 5 Thus 11, 8, and 5
