or,

\longrightarrow\sin(3x)+\sin x-3\sin(2x)=\cos(3x)+\cos x-3\cos(2x)⟶sin(3x)+sinx−3sin(2x)=cos(3x)+cosx−3cos(2x)

Taking RHS to LHS,

31.	Find the simple interest on Rs 4500 for 2 years at 6% per annum. find the amount after 2 years
Answer» Before, finding the answer. LET's find out we can find the answer. In this QUESTION, we are asked to find the Simple Interest. So, to find the Simple Interest, we must use the formula of : $\boxed{ \sf Simple \: Interest = \frac{P \times R \times T}{100} }$ Now, to find the Amount, we must add the Simple Interest with the PRINCIPAL. __________________________ Given : Principal = Rs. 4500 Rate = 6% Time = 2 years To find : Simple Interest Amount Solution : We know that, ${ \hookrightarrow \sf Simple \: Interest = \dfrac{P \times R \times T}{100} }$ ${ = \sf \dfrac{4500 \times 6 \times 2}{100} }$ ${ = \sf \dfrac{4500 \times 18}{100} }$ ${ = \sf \dfrac{45 \not 0 \not 0 \times 18}{1 \not0 \not0} }$ ${ = \sf \dfrac{45 \times 18}{1 } }$ ${ = \sf \dfrac{810}{1 } }$ ${ \sf = 810 }$ THEREFORE, Simple Interest is Rs. 810. Now, ${ \hookrightarrow \sf Amount = Principal + Simple \: Interest }$ ${ \sf = 4500 + 810 }$ ${ \sf = 5310 }$ Therefore, the Amount is Rs. 5310.

Find the simple interest on Rs 4500 for 2 years at 6% per annum. find the amount after 2 years

Answer»

Before, finding the answer. LET's find out we can find the answer.

In this QUESTION, we are asked to find the Simple Interest.
So, to find the Simple Interest, we must use the formula of :

$\boxed{ \sf Simple \: Interest = \frac{P \times R \times T}{100} }$

Now, to find the Amount, we must add the Simple Interest with the PRINCIPAL.

__________________________

Given :

Principal = Rs. 4500
Rate = 6%
Time = 2 years

To find :

Simple Interest
Amount

Solution :

We know that,

${ \hookrightarrow \sf Simple \: Interest = \dfrac{P \times R \times T}{100} }$

${ = \sf \dfrac{4500 \times 6 \times 2}{100} }$

${ = \sf \dfrac{4500 \times 18}{100} }$

${ = \sf \dfrac{45 \not 0 \not 0 \times 18}{1 \not0 \not0} }$

${ = \sf \dfrac{45 \times 18}{1 } }$

${ = \sf \dfrac{810}{1 } }$

${ \sf = 810 }$

THEREFORE, Simple Interest is Rs. 810.

Now,

${ \hookrightarrow \sf Amount = Principal + Simple \: Interest }$

${ \sf = 4500 + 810 }$

${ \sf = 5310 }$

Therefore, the Amount is Rs. 5310.

33.	Multiply the reciprocal of 9/11 by the additive inverse of -18/55
Answer» Answer: The PRODUCT of reciprocal of 9/11 and ADDITIVE inverse of -18/55 is 2/5. Step-by-step explanation: To solve this we first NEED to know what is reciprocal and additive inverse. Every NONZERO rational number a/b has its reciprocal b/a. So that, $\sf{\circ\;\dfrac{a}{b}\times\dfrac{b}{a}=\dfrac{b}{a}\times\dfrac{a}{b}=1}$ Every rational number a/b (or -a/b), there is a additive inverse -a/b (or a/b). So that, $\sf{\circ\;\dfrac{a}{b}+\dfrac{-a}{b}=0}$ So, $\sf{\circ\;Reciprocal\;of\;\dfrac{9}{11}=\dfrac{11}{9}}$ $\sf{\circ\;Additive \;inverse \;of \;\dfrac{-18}{55}=\dfrac{18}{55}}$ Now, According to the question we have to MULTIPLY 11/9 by 18/55. $\sf{\longmapsto\dfrac{11}{9}\times\dfrac{18}{55}}$ Reducing the numbers, $\sf{\longmapsto\dfrac{1}{1}\times\dfrac{2}{5}}$ Multiplying the numbers, $\sf{\longmapsto\dfrac{2}{5}}$ Hence, The product 11/9 and 18/55 is 2/5.

Multiply the reciprocal of 9/11 by the additive inverse of -18/55

Answer»

Answer:

The PRODUCT of reciprocal of 9/11 and ADDITIVE inverse of -18/55 is 2/5.

Step-by-step explanation:

To solve this we first NEED to know what is reciprocal and additive inverse.

Every NONZERO rational number a/b has its reciprocal b/a. So that,

$\sf{\circ\;\dfrac{a}{b}\times\dfrac{b}{a}=\dfrac{b}{a}\times\dfrac{a}{b}=1}$

Every rational number a/b (or -a/b), there is a additive inverse -a/b (or a/b). So that,

$\sf{\circ\;\dfrac{a}{b}+\dfrac{-a}{b}=0}$

So,

$\sf{\circ\;Reciprocal\;of\;\dfrac{9}{11}=\dfrac{11}{9}}$

$\sf{\circ\;Additive \;inverse \;of \;\dfrac{-18}{55}=\dfrac{18}{55}}$

Now,

According to the question we have to MULTIPLY 11/9 by 18/55.

$\sf{\longmapsto\dfrac{11}{9}\times\dfrac{18}{55}}$

Reducing the numbers,

$\sf{\longmapsto\dfrac{1}{1}\times\dfrac{2}{5}}$

Multiplying the numbers,

$\sf{\longmapsto\dfrac{2}{5}}$

Hence,

The product 11/9 and 18/55 is 2/5.

Answer» Given :- If the size of the interior angles of a polygon are 2a, 4a, 6a, 6a, 8a & 10A. What would be the largest and smallest interior angle of the polygon, respectively ?

If the size of the interior angles of a polygon are 2a, 4a, 6a, 6a, 8a & 10a. What would be the largest and smallest interior angle of the polygon, respectively?

Answer»

Given :- If the size of the interior angles of a polygon are 2a, 4a, 6a, 6a, 8a & 10A. What would be the largest and smallest interior angle of the polygon, respectively ?

Answer :-

we know that ,

sum of interior angles of a regular polygon with n sides is = (n - 2) * 180° .

given that,

Polygon has = 6 sides .

so,

→ 2a + 4a + 6a + 6a + 8a + 10a = (6 - 2) * 180°

→ 36a = 4 * 180°

→ a = 20 .

then,

Largest angle = 10a = 10 * 20 = 200°
Smallest angle = 2a = 2*20 = 40° .

[ NOTE :- we can find sum of interior angles if all sides are equal , or regular polygon and in that case all interior angles will also be equal .]
