1.	Find the perpendicular distance between the (3, 4) and the lines 3x + 4y =5
Answer» Solution : The PERPENDICULAR distance between the POINT (3,4) and the line 3x+4y=5 is 4 units Theory : The length perpendicular from a point $\sf\:(x_1,y_1)$ to a line ax+by+c=0 is $\rm=\|\dfrac{ax_1+by_1+c}{\sqrt{a^2+b^2}}\|$ Step by step EXPLANATION: We have to Find the perpendicular distance between the point (3,4) and the line 3x+4y=5 Let the perpendicular distance be P , and point (3,4) and line 3x+4y-5=0 Then , Perpendicular distance $\sf\:P=\|\dfrac{3(3)+4(4)-5}{\sqrt{3^2+4^2}}\|$ $\sf\implies\:P=\|\dfrac{9+16-5}{\sqrt{9+16}}\|$ $\sf\implies\:P=\|\dfrac{9+16-5}{\sqrt{9+16}}\|$ $\sf\implies\:P=\|\dfrac{25-5}{\sqrt{25}}\|$ $\sf\implies\:P=\|\dfrac{20}{5}\|$ $\sf\implies\:P=4$

1.

Find the perpendicular distance between the (3, 4) and the lines 3x + 4y =5

Answer»

Solution :

The PERPENDICULAR distance between the POINT (3,4) and the line 3x+4y=5 is 4 units

Theory :

The length perpendicular from a point $\sf\:(x_1,y_1)$ to a line ax+by+c=0 is

$\rm=|\dfrac{ax_1+by_1+c}{\sqrt{a^2+b^2}}|$

Step by step EXPLANATION:

We have to Find the perpendicular distance between the point (3,4) and the line 3x+4y=5

Let the perpendicular distance be P , and point (3,4) and line 3x+4y-5=0

Then ,

Perpendicular distance

$\sf\:P=|\dfrac{3(3)+4(4)-5}{\sqrt{3^2+4^2}}|$

$\sf\implies\:P=|\dfrac{9+16-5}{\sqrt{9+16}}|$

$\sf\implies\:P=|\dfrac{25-5}{\sqrt{25}}|$

$\sf\implies\:P=|\dfrac{20}{5}|$

$\sf\implies\:P=4$

How to Use the Distributive Property Calculator?

The procedure to use the distributive property calculator is as follows:

Step 1: Enter an expression of the form a (b+c) in the input field

Step 2: Now click the button “Submit” to get the simplified expression

Step 3: Finally, the simplification of the given expression will be displayed in a NEW window.

Distributive Property in Maths

In Mathematics, the numbers should obey the characteristic property during the arithmetic operations. The DIFFERENT properties are associative property, commutative property, distributive property, inverse property, identity property and so on. The distributive property is the one which allows us to multiply the number by a group of numbers, which are added together. The distributive property is given by: a(b+c) = ab + ac

Example

Question:

Simplify the given expression 4(2 + 8)

Solution:

Given expression: 4(2+ 8)

We know that the distributive property is given by:

a(b+c) = ab+ ac

Hence,

4(2 + 8) = 4(2) + 4(8)

=8+ 32

= 40

Therefore, 4 (2+8) is 40

Answer» Answer: C)a³b³ Step-by-step explanation: Given that, p = ab2 = a × b × b Given that, p = ab2 = a × b × band q = A3B = a × a × a × b Given that, p = ab2 = a × b × band q = a3b = a × a × a × b∴ LCM of p and q = LCM (ab2,a3b) = a × b × b × a × a = a3b2 Given that, p = ab2 = a × b × band q = a3b = a × a × a × b∴ LCM of p and q = LCM (ab2,a3b) = a × b × b × a × a = a3b2[Since, LCM is the PRODUCT of the greatest power of each prime factor INVOLVED in the numbers].

7. If two positive integers p and q can beexpressed as p = ab2 and q = a b, a, b beingprime numbers, then LCM (p, q) isNEXT(A) ab(B) a2b2(C) a3b2(D) a3b3

Answer»

Answer:

C)a³b³

Step-by-step explanation:

Given that, p = ab2 = a × b × b

Given that, p = ab2 = a × b × band q = A3B = a × a × a × b

Given that, p = ab2 = a × b × band q = a3b = a × a × a × b∴ LCM of p and q = LCM (ab2,a3b) = a × b × b × a × a = a3b2

Given that, p = ab2 = a × b × band q = a3b = a × a × a × b∴ LCM of p and q = LCM (ab2,a3b) = a × b × b × a × a = a3b2[Since, LCM is the PRODUCT of the greatest power of each prime factor INVOLVED in the numbers].

Add : 87 m 27 cm and 92 m 8 cm

Answer»

$\huge\fbox\color{gray}{Question}$

$\large\bold{Add:\:\:87m,\:27cm\:and\:92m,\:8cm}$

$\small\fbox\color{red}{Before\:to\:the\:answer,\: let's\:recap\:the\:METRIC CONVERSION}$

$\small\underline\bold{Length:}$

$$\Rightarrow1\:cm = 10\:mm\\\Rightarrow1\:DM = 10\:cm\\\Rightarrow1\:m = 100\:cm\\\Rightarrow1\:m=10\:dm\\\Rightarrow1\:km=1000\:m$$

_____________________

$\huge\fbox\color{gray}{Solution}$

$\small\bold{Before\:finding\:the\:sum\:of\:two\:measurements,}$

$\small\bold{first\:we\:have\:to\:make\:sure\:that\:they\:are\:in\:same\:metric\:units.}$

→ Here, there are two different units. So we have to convert the greater unit to smaller unit (i.e., metres to CENTIMETRES).

$\small\bold{We\:know\:that\:1\:m=100\:cm.\:So,}$

(1).. 87 m = 87 × 100

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎‎= 8700 cm

(2).. 92 m = 92 × 100

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎= 9200 cm

→ Now, we can 'cm(s)' with 'cm(s)'.

(1).. 8700 cm + 27 cm = 8727 cm

(2).. 9200 cm + 8 cm = 9208 cm

$\small\bold{Finally,}$

Add 8727 cms with 9208 cms

→ 8727 + 9208 = $\large\bold{17935\:cms}$

_____________________

$\large\fbox\color{orange}{Additional\:Steps:}$

We can convert 17935 cm to other units.

→ 17935 cm = 179350 mm

→ 17935 cm = 1793.5 dm

→ 17935 cm = 179.35 m

→ 17935 cm = 0.17935 km
