Show that 1764 is perfect square find the number whose square is 1764​

Answer»

The square root of 1764 is 42, or else wise we can cay that 42 squared is 1764. In order to show that 1764 is a PERFECT square you COULD either USE a calculator to find the answer to the square and then show that when the root is squared we get the resulting answer. If you wanted to do it without a calculator you could find the root of the number and then show it is a perfect square by INDICATING that the end result is a rational number.

The length of the longer ladder is 37 ft and climbing on it,one can climb upto a height of 35 ft. The shorter ladder is 25 ft long and it reaches to a height of 24 ft. Find the distancebetween the foot of the two ladders?​

Answer»

Answer:

5FT

Step-by-step explanation:

The TWO ladder will form Right ANGLED triangle.

Length of ladder will be the hypotenuse.

Third side of Right angled triangle having SIDES 37ft and 35ft

= √37² - 35²= √(37+35)(37-35) = √72*2=√144=12ft

Third side of Right angled triangle having sides 25ft and 24ft

=√25²-24²= √(25+24)(25-24) =√49*1 = √49 = 7ft

Distance between foot of ladder = 12-7 =5ft

If (x + 1) and (x - 2) are the factors of mx^2 + x^2 - 2x + n . find the value of m and n.​

Answer»

<P>Answer:

m=2

n=-1

Step-by-step explanation:

==> X+1 = 0      ;   X-1 = 0

==> X = -1 ; 1

POLYNOMIAL = mx³+x²-2x+n

P[1] = m[1]³+[1]²-2[1]+ n

P[1] = m+ 1 - 2 + n

==> m+n - 1

==> m+n = 1 ....{1}

P[-1] = m[-1]³+[-1]²-2[-1]+n

==> -m+1+2+n ==> -m+n+3

==> -m+n= -3...........[2]

EQ[1] AND [2]

m+n = 1

-m+n = -3

2n = -2

==> n = -1

PUTTING VALUE IN EQ[2]

-m+n = -3

-m-1 = -3

-m= -2

m = 2

पाइथागोरस प्रमेय के अनुसार एक समकोण त्रिभुज में कर्ण का वर्ग शेष दो भुजाओं के वर्गों के योग के बराबर होता है।

अर्थात,

class 10 गणित-10 त्रिभुज पाइथागोरस प्रमेय

मान लिया कि MNO एक समकोण त्रिभुज है, जिसका कोण M = 900 अर्थात समकोण है।

समकोण के सामने वाली (सम्मुख) भुजा कर्ण (Hypotenuse) कहलाती है।

समकोण के संलग्न क्षैतिज भुजा को आधार (BASE) तथा समकोण के संलग्न उर्ध्वाकार भुजा को लम्ब (PERPENDICULAR) कहा जाता है।

कर्ण को प्राय: अंग्रेजी के अक्षर

h

से निरूपित किया जाता है, चूँकि कर्ण को अंग्रेजी में Hypotenuse कहते हैं।

आधार को प्राय: अंग्रेजी के अक्षर

B

लम्ब को प्राय: अंग्रेजी के अक्षर

p

से निरूपित किया जाता है, चूँकि लम्ब को अंग्रेजी में Perpendicular कहा जाता है।

अत: पाइथागोरस प्रमेय के अनुसार,

14.Factorize 2x² – 5 xy + 3y²} and use your result tofactorize 2(3a- b)²– 5 (3a-b) (2a-b)+3(2a-b)².The factors are​

Answer»

Answer:

AB

Step-by-step explanation:

Given an algebraic expression such that,

2 {x}^{2} - 5xy + 3 {y}^{2}

To FACTORISE it,

We will use MIDDLE term splitting method.

Therefore, we will get,

= 2 {x}^{2} - 2xy - 3xy + 3 {y}^{2} \\ \\ = 2x(x - y) - 3y(x - y) \\ \\ = (x - y)(2x - 3y)

Now, another expression is such that,

2 {(3a - b)}^{2} - 5(3a - b)(2a - b) + 3 {(2a - b)}^{2}

Let's assume that,

  • x = (3a-b)
  • y = (2a-b)

Therefore, we have,

= 2 {x}^{2} - 5xy + 3 {y}^{2}

Factorising this as same as above is DONE,

Therefore, we will get,

= {(3a-b)-(2a-b)}{2(3a-b)-3(2a-b)}

= (3a-b-2a+b)(6a-2b-6a+3b)

= ab

Hence, the REQUIRED value is ab.

The sum of 2 numbers is 17 and their product is 66

Answer»

The two numbers are 11 and 6

Step-by-step explanation:

LET the numbers be x and y. Then ACCORDING to the condition

x + y = 17 ...... eq (1)

xy =66  ........  eq (2)

From equation (2), we have

x = 66/y

Substituting the VALUE of x in eq (1)

66/y + y = 17

(66 + y2 )/y= 17

66 + y2 = 17y

y2 -17y +66 = 0

Now, we need to FACTORIZE the it

y2 -11y -6y +66 = 0

y(y-11) -6 (y-11) = 0

(y-11)(y-6)=0

This shows,

y = 11,6
