UR ANSWER

Diameter of the semicircular protractor =14cm

Radius =

14/2cm=7cm

Perimeter of SEMICIRCLE =πr+d

Perimeter of semicircular protractor = 7

22×7+14=22+14=36cm

Answer» Basic Concept :- There are 4 methods to SOLVE this type of pair of linear equations. 1. Method of Substitution 2. Method of Eliminations 3. Method of Cross Multiplication 4. GRAPHICAL Method We prefer here Method of Eliminations. To solve systems using elimination, follow this procedure: The Elimination Method Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. Step 2: Subtract the SECOND equation from the first to reduce the equation to one variable. Step 3: Solve this new equation for one variable. Step 4: Substitute the value of this variable into either of Equation 1 or Equation 2 above and solve for other variable. Let's solve the PROBLEM now!! Given equations are $\rm :\longmapsto\:ax + by = a - b - - (1)$ $\rm :\longmapsto\:bx - ay = a + b - - (2)$ On multiply equation (1) by b, we get $\rm :\longmapsto\:abx + {b}^{2} y = ab - {b}^{2} - - (3)$ On multiplying equation (2) by a, we get $\rm :\longmapsto\:abx - {a}^{2} y = {a}^{2} + ab - - (4)$ Subtracting equation (4) from equation (3), we get $\rm :\longmapsto\: {b}^{2} y + {a}^{2} y = - {b}^{2} - {a}^{2}$ $\rm :\longmapsto\:y \: \cancel{( {a}^{2} + {b}^{2})} = - \: \cancel{( {b}^{2} + {a}^{2})}$ $\bf\implies \:y \: = \: - \: 1$ Now, Substitute the value of y in equation (1), we get $\rm :\longmapsto\:ax - b = a - b$ $\rm :\longmapsto\:ax = a$ $\bf\implies \:x \: = \: 1$ $\overbrace{ \underline { \boxed { \bf \therefore \: The \:solution\: is \: x \: = 1 \: \: and \: \: y \: = \: - 1)}}}$

Solve: ax + by = a - b and bx - ay = a + b

Answer»

Basic Concept :-

There are 4 methods to SOLVE this type of pair of linear equations.

1. Method of Substitution

2. Method of Eliminations

3. Method of Cross Multiplication

4. GRAPHICAL Method

We prefer here Method of Eliminations.

To solve systems using elimination, follow this procedure:

The Elimination Method

Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient.

Step 2: Subtract the SECOND equation from the first to reduce the equation to one variable.

Step 3: Solve this new equation for one variable.

Step 4: Substitute the value of this variable into either of Equation 1 or Equation 2 above and solve for other variable.

Let's solve the PROBLEM now!!

Given equations are

$\rm :\longmapsto\:ax + by = a - b - - (1)$

$\rm :\longmapsto\:bx - ay = a + b - - (2)$

On multiply equation (1) by b, we get

$\rm :\longmapsto\:abx + {b}^{2} y = ab - {b}^{2} - - (3)$

On multiplying equation (2) by a, we get

$\rm :\longmapsto\:abx - {a}^{2} y = {a}^{2} + ab - - (4)$

Subtracting equation (4) from equation (3), we get

$\rm :\longmapsto\: {b}^{2} y + {a}^{2} y = - {b}^{2} - {a}^{2}$

$\rm :\longmapsto\:y \: \cancel{( {a}^{2} + {b}^{2})} = - \: \cancel{( {b}^{2} + {a}^{2})}$

$\bf\implies \:y \: = \: - \: 1$

Now, Substitute the value of y in equation (1), we get

$\rm :\longmapsto\:ax - b = a - b$

$\rm :\longmapsto\:ax = a$

$\bf\implies \:x \: = \: 1$

$\overbrace{ \underline { \boxed { \bf \therefore \: The \:solution\: is \: x \: = 1 \: \: and \: \: y \: = \: - 1)}}}$

A line segment AB is to be divided in the ratio 2:3 then ray AX will be drawn such that angle BAX is ______ angle.

Answer» ONG>Answer:

So a total of 5 equal parts are needed.

Step-by-step EXPLANATION:

The line is to be divided in 2:3

Let the parts of line be 2X and 3x

2x=x+x

So 2x has 2 equal parts.

3x=x+x+x

So 3x has 3 equal parts.

So a total of 5 equal parts are needed.

Answer» ONG>Answer: 125 km/h Step-by-step explanation: Speed s = Distance d/Time TAKEN t ie s = d/t. s = 100 km/h, t = 3 h 20 min = 3 1/3 h = (10/3)h. 100 = d/(3 1/3) = d /(10/3) => d = (1 000/3) km. 2 h 40 min = 2 2/3 h = 8/3 h s = d/t = (1 000/3)/(8/3) = 125 km/h.

23.

A train traveling at an average speed of 100km/h covers a certain distance in 3 hours 36 minutes. At what average speed must the train travel to cover the same distance in 2hours 30 minutes

Answer» ONG>Answer:

125 km/h

Step-by-step explanation:

Speed s = Distance d/Time TAKEN t ie s = d/t. s = 100 km/h, t = 3 h 20 min = 3 1/3 h = (10/3)h.

100 = d/(3 1/3) = d /(10/3) => d = (1 000/3) km.

2 h 40 min = 2 2/3 h = 8/3 h

s = d/t = (1 000/3)/(8/3) = 125 km/h.

If f(x) =lower lt 0, upper lt x integration e^2tsin3t dt, then f'(x)= –

Answer»

$\large\underline{\sf{Given- }}$

$\rm :\longmapsto\: \sf \: f(x) = \sf \displaystyle\int^{x} _{0} \sf \: {e}^{2t} \: sin3t \: dt$

$\large\underline{\sf{To\:Find - }}$

$\rm :\longmapsto\:f'(x)$

$\begin{gathered}\Large{\bold{{\underline{Formula \: Used - }}}} \end{gathered}$

$\sf \: Differentiation \: under \: the \: integral \: <klux>SIGN</klux> \:$

$\bf \: The \: Leibniz \: Rule$

$\sf \: \dfrac{d}{dx}\sf \displaystyle\int^{b} _{a} \sf \:f(x,t)dt = \sf \displaystyle\int^{b} _{a} \sf \: \dfrac{ \partial}{ \partial \: x} f(x,t)dt + \dfrac{db}{dx}f(x,b) - \dfrac{da}{dx}f(x,a)$

$\large\underline{\sf{Solution-}}$

Given that

$\rm :\longmapsto\: \sf \: f(x) = \sf \displaystyle\int^{x} _{0} \sf \: {e}^{2t} \: sin3t \: dt$

On differentiating both sides W. r. t. x, we get

$\rm :\longmapsto\: \sf \: \dfrac{d}{dx}f(x) = \dfrac{d}{dx}\sf \displaystyle\int^{x} _{0} \sf \: {e}^{2t} \: sin3t \: dt$

$\rm :\longmapsto\: \sf \: f'(x) = \sf \displaystyle\int^{x} _{0} \sf \:\dfrac{ \partial}{ \partial \: x} \: {e}^{2t} \: sin3t \: dt + \dfrac{d}{dx}(x) \: {e}^{2x} sin3x - 0$

$\rm :\longmapsto\:f'(x) = 0 + 1 \times {e}^{2x} sin3x$

$\bf\implies \:f'(x) = {e}^{2x} sin3x$
