find inclination made by the line joining points (2a,2aroot3) and (3a,3aroot3) in direction of X-axis?

Answer»

$\begin{gathered}\begin{gathered}\bf \: Given \: coordinates \: are \: \begin{cases} &\sf{A(2a, 2a \sqrt{3} )} \\ &\sf{B(3a, 3a \sqrt{3} )} \end{cases}\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}\bf \:To\:find - \begin{cases} &\sf{<klux>ANGLE</klux> \: makes \: with \: direction \: of \: x - <klux>AXIS</klux>} \end{cases}\end{gathered}\end{gathered}$

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

Let suppose that line AB makes an angle θ with positive direction of x - axis.

We know,

If line passes through TWO points A (a, b) and B (c, d) and makes an angle θ with positivedirectionofx - axis, then slope (m) of line is

$\sf \: m \: = \: \dfrac{d - b}{c - a} = tan \theta \:$

Here,

$\: \: \: \: \: \: \bull \: \sf \: a \: = \: 2a$

$\: \: \: \: \: \: \bull \: \sf \: b \: = \: 2a \sqrt{3}$

$\: \: \: \: \: \: \bull \: \sf \: c \: = \: 3a$

$\: \: \: \: \: \: \bull \: \sf \: d \: = \: 3a \sqrt{3}$

So, on substituting the values, we get

$\bf \: tan \theta \: = \rm \: \dfrac{3a \sqrt{3} - 2a \sqrt{3} }{3a - 2a}$

$\bf \: tan \theta \: = \rm \: \dfrac{a \sqrt{3} }{a}$

$\bf \: tan \theta \: = \: \rm \: \sqrt{3}$

$\bf\implies \: \theta \: = \: 60 \degree$

Additional INFORMATION

1. Two LINES having slope m and M are parallel iff m = M.

2. Two lines having slope m and M are perpendicular iff mM = - 1

3. If line is parallel to x - axis, its slope is 0.

4. If a line is parallel to y - axis, its slope is not defined.

5. If 3 points A, B, C are collinear, then slope of AB = slope of BC.

24.

The center angle of the circle is 60 ° and the diameter is 6 cm. Draw this circle. Draw a circle touching this circle and the arc,with whole exeplention

Answer»

Solution :

For semicircle with diameters PS,

Radius = 6 cm

∴ Area of such semicircle =12πr2=12×227×62=3967cm2

Diameter PS=6+6=12cm

∴PQ=QR=RS=4cm

For semicircle with diameter QS, radius = 4 cm

∴ Its area =12πr2=12×227×42=1767cm2

For semicircle with diameter PQ, radius = 2 cm

∴ Its area =12×227×22=447cm2

∴ Area of shaded region =3967−1767+447=2647=37.71cm2

Given: PS = diameter of circle

and radius (R) = 6 cm

diameter PS=2×r

⇒PS=2×6 PS=12cm

PQ=QR=RS=123=4cm each.

Hence, REQUIRED perimeters = circumference of semicircle with radius 6 cm + circumference of semicircle with radius 4 cm + circumference of semicircle with radius 2 cm.

6π+4π+2π=12πcm

Answer»

Step-by-step explanation:

2x - y = 1 )-------(1)

2x + 2y = 10 )---------(2)

from EQUATION (2)

2x +2y = 10
2(x+y) = 10
x+ y = 5
x = 5-y )--------(3)

putting equation (3) in (1)

2x - y = 1
2(5 - y) - y = 1
10 - 2y -y = 1
10 -3y = 1
-3y = 1-9
-3y = -8
$y = \frac{8}{3}$

putting VALUE of y in question (3)

$x = 5 - \frac{8}{3}$
$x = \frac{15 - 8}{3}$
$x = \frac{7}{3}$

35.	an integer greater than 100 has its unit digit twice that of its ten digit. The hundreds digit is 25 percent of the ten digit. If the sum of all the digit is 13 ,what is the value of the integer?
Answer» Answer: 148 is the value of integer . Step-by-step explanation: Let the TEN digit : X So , unit digit : 2X ( as unit digit is twice ten digit) Hundred digit : X/4 ( as hundred digit is 25% of ten digit = 25/100×X = 1/4X = X/4 ) X/4 + X + 2X = 13 ( as sum of all digits is 13 ) Take LCM = 4 X + 4X +8X __________ = 13 4 13X/4 = 13 By transposing LHS to RHS X = 13×4 ____ 13 X = 4 So , unit digit = 2X = 2×4 = 8 Ten digit = X= 4 Hundred digit = 25% × X = 1 So , answer is 148 .

an integer greater than 100 has its unit digit twice that of its ten digit. The hundreds digit is 25 percent of the ten digit. If the sum of all the digit is 13 ,what is the value of the integer?

Answer»

Answer:

148 is the value of integer .

Step-by-step explanation:

Let the TEN digit : X

So , unit digit : 2X ( as unit digit is twice ten digit)

Hundred digit : X/4 ( as hundred digit is 25% of ten digit = 25/100×X = 1/4X = X/4 )

X/4 + X + 2X = 13 ( as sum of all digits is 13 )

Take LCM = 4

X + 4X +8X

__________ = 13

4

13X/4 = 13

By transposing LHS to RHS

X = 13×4

____

13

X = 4

So , unit digit = 2X = 2×4 = 8

Ten digit = X= 4

Hundred digit = 25% × X = 1

So , answer is 148 .

Answer»

Answer = 27 Boys

GIVEN : ↴

$\sf \: The \: ratio \: of \: the \: <klux>NUMBER</klux> \: of \: boys \: and \: girls \: in \: a \: class \: is \: 9 : 5.$

$\sf \: Total \: number \: of \: students \: in \: the \: class \: is \: 42.$

To Find : ↴

$\sf \: We \: need \: to \: find \: the \: number \: of \: boys.$

So, let's START : ↴

$\sf \: Boys \: = \: 9x$

$\sf \: Girls \: = \: 5x$

$\sf \longrightarrow \: 9x \: + \: 5x = 42$

$\sf \longrightarrow \: 14x \: = 42$

$\sf \longrightarrow \: x \: = \dfrac{42}{14}$

$\sf \longrightarrow \: x \: = \dfrac{ \cancel{42}}{\cancel{14}} = 3$

$\sf \: Till \: here \: We \: have \: just \: find \: the \: value \: of \: x$

$\sf \: Now, \: We \: will \: find \: the \: number \: of \: Boys.$

$\sf \: Number \: of \: Boys \: = \: 9 \times 3 \: = \: 27$

$\sf \: So, \: the \: No. \: of \: Boys \: = \: 27$

Answer = 27 Boys

_________________________

Some More INFORMATION : ↴

$\sf \: \: The \: Number \: of \:Girls \: = \: 5 \times 3 = 15$

$\sf \: So, \: the \: No. \: of \: Girls \: = \: 15$

_________________________

Let's VERIFY Our Answer : ↴

To verify our Answer we have to add 27 and 15. If the sum of both the numbers is 42, then it means that our Answer is correct.

So, Let's Check : ↴

$\sf \: 27 \: + \: 15 \: = \:42$

Hence the Number if Boys are 27

And the number of Gìrls are 15.
