2.	(M²_7M-11) (mas) send solution
Answer» Answer: M= (7+√94)/2 & M= (7-√94)/2 Step-by-step EXPLANATION: Given that, (M^2-7M-11)=0 there is a formula I.e; for the EQUATION ax²+bx+c=0 x=[-b±√(b²-4ac)]/2a Here,a=1,b=-7,c=-11,x=M Now, M=[-(-7)±√((-7)²-4(1)(-11))]/2(1) M=[7±√(49+44)]/2 M=(7±√94)/2 M=(7+√94)/2 & M=(7-√94)/2 HOPE THIS WOULD BE HELPFUL FOR YOU

2.

(M²_7M-11) (mas) send solution

Answer»

Answer:

M= (7+√94)/2 & M= (7-√94)/2

Step-by-step EXPLANATION:

Given that,

(M^2-7M-11)=0

there is a formula I.e;

for the EQUATION ax²+bx+c=0 x=[-b±√(b²-4ac)]/2a

Here,a=1,b=-7,c=-11,x=M

Now,

M=[-(-7)±√((-7)²-4(1)(-11))]/2(1)

M=[7±√(49+44)]/2

M=(7±√94)/2

M=(7+√94)/2 & M=(7-√94)/2

Answer» Let the age of his son be 'x' Then his FATHER's age becomes 2x Doubling age of father: 2(2x)= 4X Now, when the son's age is ADDED to this it becomes 95 4x + x =95 5x = 95 x = 19 FATHER'S AGE 2x = 19×2=38 SON'S AGE = x = 19

7.

The fathers age and twice the age of his son is 70. If we double the age of the father and add it tothe age of his son the sum is 95.

Answer»

Let the age of his son be 'x'

Then his FATHER's age becomes 2x

Doubling age of father: 2(2x)= 4X

Now, when the son's age is ADDED to this it becomes 95

4x + x =95

5x = 95

x = 19

FATHER'S AGE 2x = 19×2=38

SON'S AGE = x = 19

Answer»

◘ Question ◘

FIND the zeroes of the given polynomials.

(i) p(x) = 3X

(ii) p(x) = x² + 5X + 6

(III) p(x) = (x + 2)(x + 3)

(iv) p(x) = x⁴ - 16

◘ We Must Know ◘

To find the zero(s) of a given polynomial, it must be equated with zero. The possible values for 'x' will be the zeros of the polynomial.

◘ Solution ◘

$\sf{(i)\ p(x)=3x}\\\\\sf{\dashrightarrow 3x=0}\\\\\sf{\dashrightarrow x=\dfrac{0}{3} }\\\\\sf{\color{magenta}{\dashrightarrow x=0}}$

HENCE, the zero of this polynomial p(x) is 0.

$\rule{180}2$

$\sf{(ii)\ p(x)=x^2+5x+6}\\\\\sf{\dashrightarrow x^2+5x+6=0}\\\\\sf{\dashrightarrow x^2+2x+3x+6=0}\\\\\sf{\dashrightarrow x(x+2)+3(x+2)=0}\\\\\sf{\dashrightarrow (x+2)(x+3)=0}\\\\\sf{\dashrightarrow (x+2)=0\:\:or\:\:(x+3)=0}\\\\\sf{\color{magenta}{\dashrightarrow x=-2}\:\:or\:\:\color{magenta}{x=-3}}$

Hence, the zero of this polynomial p(x) are -2 & -3.

$\rule{180}2$

$\sf{(iii)\ p(x)=(x+2)(x+3)}\\\\\sf{\dashrightarrow (x+2)(x+3)=0}\\\\\sf{\dashrightarrow (x+2)=0\:\:or\:\:(x+3)=0}\\\\\sf{\color{magenta}{\dashrightarrow x=-2}\:\:or\:\:\color{magenta}{x=-3}}$

Hence, the zero of this polynomial p(x) are -2 & -3.

$\rule{180}2$

$\sf{(iv)\ p(x)=x^4-16}\\\\\sf{\dashrightarrow x^4-16=0}\\\\\sf{\dashrightarrow x^4=16}\\\\\sf{\dashrightarrow x=\sqrt[4]{16} }\\\\\sf{\color{magenta}{\dashrightarrow x=\pm 2}}$

Hence, the zeros of this polynomial p(x) are +2 & -2.

Answer» Answer: 44 Step-by-step explanation: first, we need to find a PERFECT square number which is above and NEAREST to 1400 by using LONG division method that would be 38² which is equal to 1444. Here, No. of plants = 1400. Since the remainder is 20 therefore, 38² > 1400 Hence, the number to be subtracted. if the number is LESS than 1400 then we need to add. = 38² - 1400 = 1444 - 1400 = 44 hence, the gardener required 44 more plants. hope it helps.

Answer»

Answer:

44

Step-by-step explanation:

first, we need to find a PERFECT square number which is above and NEAREST to 1400 by using LONG division method that would be 38² which is equal to 1444.

Here, No. of plants = 1400.

Since the remainder is 20

therefore, 38² > 1400

Hence, the number to be subtracted. if the number is LESS than 1400 then we need to add.

= 38² - 1400

= 1444 - 1400

= 44

hence, the gardener required 44 more plants.
