Answer» Answer: HEYA mate here is ur answer → Divisibility rule of 4 The basic rule for divisibility by 4 is that if the number formed by the last two DIGITS in a number is DIVISIBLE by 4, the original number is divisible by 4; this is because 100 is divisible by 4 and so adding hundreds, thousands, ETC. is simply adding another number that is divisible by 4. → Divisibility rule of 6 A number is divisible by 6 if it is divisible by 2 and 3 both. Consider the following numbers which are divisible by 6, using the test of divisibility by 6: 42, 144, 180, 258, 156.

The basic rule for divisibility by 4 is that if the number formed by the last two DIGITS in a number is DIVISIBLE by 4, the original number is divisible by 4; this is because 100 is divisible by 4 and so adding hundreds, thousands, ETC. is simply adding another number that is divisible by 4.

Answer» Answer: Step-by-step explanation: Let α and β are the zeroes of a quadratic polynomial. Given: ONE zero(α)= 3+√2 Sum of its zeroes (α+ β)= 6 (α+ β)= 6 3+√2 + β= 6 β = 6- (3+√2)= 6 -3 -√2= 3-√2 β= 3 -√2 Product of zeroes (α. β) = (3+√2) (3-√2) α. β =( 3)² - (√2)²= 9 - 2= 7 [(a+b) (a-b)= a² - b²] α. β = 7 Required Polynomial= k [x²-(Sum of zeroes)X +( Product of zeroes)] = k[ x² -(α+ β)x +(α. β], where k is a non zero real number. = x² -(6)x + (7) [ here k = 1] = x² - 6x + 7 Hence, a quadratic polynomial is x² - 6x + 7.

Form a quadratic polynomial whose one zero is 3+√2

Answer»

Answer:

Step-by-step explanation:

Let α and β are the zeroes of a quadratic polynomial.

Given: ONE zero(α)= 3+√2

Sum of its zeroes (α+ β)= 6

(α+ β)= 6

3+√2 + β= 6

β = 6- (3+√2)= 6 -3 -√2= 3-√2

β= 3 -√2

Product of zeroes (α. β) = (3+√2) (3-√2)

α. β =( 3)² - (√2)²= 9 - 2= 7

[(a+b) (a-b)= a² - b²]

α. β = 7

Required Polynomial= k [x²-(Sum of zeroes)X +( Product of zeroes)]

= k[ x² -(α+ β)x +(α. β], where k is a non zero real number.

= x² -(6)x + (7) [ here k = 1]

= x² - 6x + 7

Hence, a quadratic polynomial is x² - 6x + 7.

(the differentiation method is appropriate here) To determine which point maximizes the function.

+ Find the greatest value for the expression (a+x) ^3(a-x)^4 for x

Answer»

Answer:

To find greatest value of;

[(a+x)^3 ][(a-x)^4]=f (x) (say)

We are to find the point(s) of extremum of the given function. (the differentiation method is appropriate here)

To determine which point maximizes the function.

Given; x (a-x)>0 ( log function can be imposed upon the given function for ease of calculation)

So; taking log on given function we get;

log (f (x))= 3log (a+x)+4log (a-x)=g (x) (LET)

Now; differentiating f (x) and finding the extreme points by equating to 0 is equivalent to differentiating log (f (x)) and finding the extreme points, as log(.) function is monotonic.

So; d/dx (log (f (x))=0

Or, d/dx (3log (a+x)+4log (a-x))=0

Or,[ 3/(a+x)]-[4/(a-x)]=0

Or, 3/(a+x)=4/(a-x)

Or, (a-x)/(a+x)=4/3

Or,2a/-2x=7/1 (by componendo and DIVIDENDO)

Or, x=-a/7

Now to check if the extremun point x=-a/7 is MAXIMA or not;DOUBLE differentiation log (f (x))

g’’(x)[at x=-a/7]

=[-3/(a+x)^2]+[4 /(a-x)^2] (at x=-a/7)

=[(7/2)^2][(-1/12)+(1/8)] < 0

So according to rule maxima exists at ;

x=-a/7

The required MAXIMUM is ;

[(a-7/a)^3][(a+7/a)^4]

=[(2a/7)^7][12^3×4]

26.	A circular wire is cut from a circle of radius 7.5 cm and wounded over a circumference of circular wheel of radius 120 cm.Find the angle made at centre of wheel by the wire.Answer is π/8write the step by step deviation
Answer» Step-by-step explanation: Here, Circumference of the circle = 2πr =2π ×7.5 cm = 15π cm Now, circumference of the wheel= 2πr = 2π×120cm = 240π cm The circumference of the wheel is at 360° as it is the complete circle whereas the new wire radius has changed and its circumference will not totally cover the wheel, So here, LET x be the TOTAL angle of the SMALLER C. 240πcm = 360° 15π cm = x° By cross multiplication we get 240πcm× x = 360×15πcm x = 5400/240 = 22.5° And your ans= π/8 = 180/8= 22.5

A circular wire is cut from a circle of radius 7.5 cm and wounded over a circumference of circular wheel of radius 120 cm.Find the angle made at centre of wheel by the wire.Answer is π/8write the step by step deviation

Answer»

Step-by-step explanation:

Here,

Circumference of the circle = 2πr

=2π ×7.5 cm = 15π cm

Now, circumference of the wheel= 2πr

= 2π×120cm

= 240π cm

The circumference of the wheel is at 360° as it is the complete circle whereas the new wire radius has changed and its circumference will not totally cover the wheel,

So here, LET x be the TOTAL angle of the SMALLER C.

240πcm = 360°

15π cm = x°

By cross multiplication we get

240πcm× x = 360×15πcm

x = 5400/240 = 22.5°

And your ans= π/8 = 180/8= 22.5

Please solve and don't spam or write anything unnecessarily it is a request ,question given below .

Answer»

$\LARGE{ \underline{ \purple{ \sf{Required \: answer:}}}}$

GIVEN:

$\rm{ \dfrac{ log(a) }{5} = \dfrac{ log(<klux>B</klux>) }{6} = \dfrac{ log(c) }{7} }$

We have to FIND the value of b² according to the above data.

Let,

$\rm{ \dfrac{ log(a) }{5} = \dfrac{ log(b) }{6} = \dfrac{ log(c) }{7} = k}$

Then,

log a = 5K
log b = 6k
log c = 7k

When the base of the logarithm is not mentioned, it is taken to be of base 10.

a = $\rm{{10}^{5k} }$
b = $\rm{{10}^{6k} }$
c = $\rm{{10}^{5k} }$

We have to find the value of b²

⇛ $\rm{({{10}^{6k}})^{2} }$

⇛ $\rm{{10}^{12k} }$

This can be written as,

⇛ $\rm{{10}^{5k + 7k} }$

⇛ $\rm{{10}^{5k} }\times\rm{{10}^{7k} }$

⇛ a × c

Thus, the required value of b² is ac.

And we are done...

In AABC, 2B = 90°, AB = (2x + 1) cm and BC = (x + 1) cm. If the area of the AABC is60 cm?, find its perimeter.

Answer»

Correct Question:

In ∆ ABC, B = 90°, AB= (2x + 1) cm, and BC = (x + 1) cm. If the area of the ∆ ABC is 60 cm², find it's PERIMETER?

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\setlength{\unitlength}{1.9cm}\begin{picture}(6,2)\linethickness{0.5mm}\put(7.7,2.9){\large\sf{A}}\put(7.7,1){\large\sf{B}}\put(10.6,1){\large\sf{C}}\put(8,1){\line(1,0){2.5}}\put(8,1){\line(0,2){1.9}}\qbezier(10.5,1)(10,1.4)(8,2.9)\put(8.8,0.7){\sf{\large{(x + 1)}}}\put(8.2,1){\line(0,1){0.2}}\put(8,1.2){\line(3,0){0.2}}\put(7.1,1.8){\sf (2x + 1)}\end{picture}$

⠀

$\frak{Here} \begin{cases} & \sf{Base = \bf{x + 1}} \\ & \sf{Perpendicular = \bf{2x + 1}} \end{cases}\\ \\$

We KNOW that,

⠀

${\boxed{\sf{\purple{Area_{\; \triangle} = \dfrac{1}{2} \times Base \times Height}}}}\\ \\$

Now, Putting values,

⠀⠀

$:\implies\sf \dfrac{1}{2} \times (x + 1) \times (2x + 1) = 60\\ \\$

$:\implies\sf \dfrac{1}{2} (2x^2 + 3x + 1) = 60\\ \\$

$:\implies\sf 2x^2 + 3x + 1 = 120\\ \\$

$:\implies\sf 2x^2 + 3x - 119 = 0\\ \\$

So,

⠀⠀

$:\implies\sf x = \dfrac{- 3 \pm \sqrt{3^2 - 4(2)(-119)}}{2(2)}\\ \\$

$:\implies\sf x = \dfrac{- 3 \pm \sqrt{9 + 952}}{4}\\ \\$

$:\implies\sf x = \dfrac{- 3 \pm 31}{4}\\ \\$

$:\implies\sf x = 7, \dfrac{-34}{4}\\ \\$

Here, value of x can't be negative.

⠀⠀

So,

⠀⠀

$:\implies{\boxed{\frak{\pink{x = 7}}}}\;\bigstar\\ \\$

Therefore,

⠀⠀

AB, (2x + 1) = 2 × 7 = 1 = 15 cm

BC, (x + 1) = 7 + 1 = 8 cm

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

☯ Now, finding AC which is Hypotenuse of ∆ ABC,

⠀⠀

★ Using Pythagoras Theorem,

⠀⠀

${\boxed{\sf{\purple{H^2 = B^2 + P^2}}}}\\ \\$

$:\implies\sf H^2 = 8^2 + 15^2\\ \\$

$:\implies\sf H^2 = 64 + 225\\ \\$

$:\implies\sf H^2 = 289\\ \\$

$:\implies\sf \sqrt{H^2} = \sqrt{289}\\ \\$

$:\implies\bf H = 17\;cm\\ \\$

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

☯ Now, Finding Perimeter of ∆ ABC,

⠀⠀

$:\implies\sf Perimeter = AB + BC + CD\\ \\$

$:\implies\sf Perimeter = 15 + 8 + 17\\ \\$

$:\implies{\boxed{\frak{\pink{Perimeter = 40\;cm}}}}\;\bigstar\\ \\$

$\therefore\;{\underline{\sf{Hence,\;The\; perimeter\;of\; \triangle\;ABC\;is\; \bf{40\;cm}.}}}$
