Answer» ANSWER: a) 19.5 is the answer. b) 0.26 is the answer. c) 4 is the answer. Step-by-step explanation: a) (3+√5) (2+√3) = (3+2.23) (2+1.73) = (5.23) (3.73) = 19.5. b) (√5-√3)² is SIMILAR as (a- b)² formula so, a=√5,b=√3 and the formula is a²-2ab+b² when we use that formula (√5-√3)² = (√5)²-2√15+(√3)² = (5)-2√15+(3) = 8-2√15 = 8-2(3.87) = 8-7.74 = 0.26 c) (√11+√7) (√11-√7) is similar as (a+b) (a-b) formula so, a=√11,b=√7 and the formula is a²-b² when we use that formula (√11+√7) (√11-√7) = (√11)²- (√7)² = (11) - (7) = 4 HOPE you UNDERSTAND and it helps.

4.

Help for my question pls

Answer»

ANSWER:

a) 19.5 is the answer.

b) 0.26 is the answer.

c) 4 is the answer.

Step-by-step explanation:

a) (3+√5) (2+√3) = (3+2.23) (2+1.73)

= (5.23) (3.73)

= 19.5.

b) (√5-√3)² is SIMILAR as (a- b)² formula so, a=√5,b=√3 and the formula is a²-2ab+b² when we use that formula

(√5-√3)² = (√5)²-2√15+(√3)²

= (5)-2√15+(3)

= 8-2√15

= 8-2(3.87)

= 8-7.74

= 0.26

c) (√11+√7) (√11-√7) is similar as (a+b) (a-b) formula so, a=√11,b=√7 and the formula is a²-b² when we use that formula

(√11+√7) (√11-√7) = (√11)²- (√7)²

= (11) - (7)

= 4

HOPE you UNDERSTAND and it helps.

5.	11. Find the equation of the locus of P, A=(2,3) B=(2,-3) and PA+PB=8.
Answer» ANSWER: Step-by-step explanation: GIVEN, Co-ordinates of :- A = ( 2 , 3 ) B = ( 2 , - 3 ) Let. Co-ordinated of 'P' be :- P = (x , y) PA + PB = 8 To Find :- Equation of the locus. Solution :- PA + PB = 8 PA = 8 - PB SQUARING on both sides :- $(PA)^2=(8-PB)^2$ $(PA)^2=64-16PB+(PB)^2$ Let it be equation - 1 Distance Formula :- $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ According to PA :- (x , y) = (x_1 , y_1) (2 , 3) = (x_2 , y_2) $(PA)^2 = \left(\sqrt{(2-x)^2+(3-y)^2}\right)^{2}$ $= 4 - 4x + x^2 + 9 - 6y + y^2$ $= x^2+y^2-4x-6y+13$ According to PB :- (x , y) = (x_1 , y_1) (2 , -3) = (x_2 , y_2) $(PB)^2 = \left(\sqrt{(2-x)^2+(-3-y)^2}\right)^{2}$ $=4-4x+x^2+y^2+6y+9$ $=x^2+y^2-4x+6y+13$ Substituting Value in equation - 1:- $x^2+y^2-4x-6y+13 = 64-16PB+x^2+y^2-4x+6y+13$ $-12y-64=-16PB$ $-4(3y+16)=-4(4PB)$ $3y+16=4PB$ Squaring on Both sides :- $(3y+16)^2=(4PB)^2$ $9y^2+96y+256=16(PB)^2$ Substituting Value of (PB)^2 :- $9y^2+96y+256=16(x^2+y^2-4x+6y+13)$ $9y^2+96y+256=16x^2+16y^2-64x+96y+208$ $16x^2+16y^2-64x+96y+208-9y^2-96y-256=0$ $16x^2+7y^2-64x-48=0$ Since the equation of the locus is :- $16x^2+7y^2-64x-48=0\\$

11. Find the equation of the locus of P, A=(2,3) B=(2,-3) and PA+PB=8.

Answer»

ANSWER:

Step-by-step explanation:

GIVEN,

Co-ordinates of :-

A = ( 2 , 3 )

B = ( 2 , - 3 )

Let. Co-ordinated of 'P' be :-

P = (x , y)

PA + PB = 8

To Find :-

Equation of the locus.

Solution :-

PA + PB = 8

PA = 8 - PB

SQUARING on both sides :-

$(PA)^2=(8-PB)^2$

$(PA)^2=64-16PB+(PB)^2$

Let it be equation - 1

Distance Formula :-

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

According to PA :-

(x , y) = (x_1 , y_1)

(2 , 3) = (x_2 , y_2)

$(PA)^2 = \left(\sqrt{(2-x)^2+(3-y)^2}\right)^{2}$

$= 4 - 4x + x^2 + 9 - 6y + y^2$

$= x^2+y^2-4x-6y+13$

According to PB :-

(x , y) = (x_1 , y_1)

(2 , -3) = (x_2 , y_2)

$(PB)^2 = \left(\sqrt{(2-x)^2+(-3-y)^2}\right)^{2}$

$=4-4x+x^2+y^2+6y+9$

$=x^2+y^2-4x+6y+13$

Substituting Value in equation - 1:-

$x^2+y^2-4x-6y+13 = 64-16PB+x^2+y^2-4x+6y+13$

$-12y-64=-16PB$

$-4(3y+16)=-4(4PB)$

$3y+16=4PB$

Squaring on Both sides :-

$(3y+16)^2=(4PB)^2$

$9y^2+96y+256=16(PB)^2$

Substituting Value of (PB)^2 :-

$9y^2+96y+256=16(x^2+y^2-4x+6y+13)$

$9y^2+96y+256=16x^2+16y^2-64x+96y+208$

$16x^2+16y^2-64x+96y+208-9y^2-96y-256=0$

$16x^2+7y^2-64x-48=0$

Since the equation of the locus is :-

$16x^2+7y^2-64x-48=0\\$

10.	5) Find the height of a cuboid whose volume is 1360 cm2 and base area is 272 cm2Respectively.
Answer» Answer :- The HEIGHT of the cuboid is 5 CM. To find :- The height of a cuboid whose VOLUME is 1360 cm² and base area is 272 cm². Step-by-step explanation :- Here, we have to find the height of the cuboid! We know that :- $\underline{\boxed{\sf Base\: Area = L \times B}}$ Where, L = Length. B = Breadth. Hence, $\underline{\boxed{\sf L \times B = 272 \: cm^2}}$ Now, we know that :- $\underline{\boxed{\sf Volume \: of \: a \: cuboid = L \times B \times H}}$ Where, L = Length. B = Breadth. H = Height. Here, Length × Breadth = 272 cm². Volume = 1360 cm². Let the height be h. Substituting the given VALUES in this formula, $\rm 1360 = 272 \times h$ Multiplying 272 with h, $\rm 1360 = 272h$ Transposing 272 from RHS to LHS, changing it's sign, $\rm \dfrac{1360}{272} = h$ DIVIDING 1360 by 272, $\overline{\boxed{\rm 5 \: cm = h}}$ ________________________________ Hence, the height of the cuboid is 5 cm.

5) Find the height of a cuboid whose volume is 1360 cm2 and base area is 272 cm2Respectively.

Answer»

Answer :-

The HEIGHT of the cuboid is 5 CM.

To find :-

The height of a cuboid whose VOLUME is 1360 cm² and base area is 272 cm².

Step-by-step explanation :-

Here, we have to find the height of the cuboid!

We know that :-

$\underline{\boxed{\sf Base\: Area = L \times B}}$

Where,

L = Length.
B = Breadth.

Hence,

$\underline{\boxed{\sf L \times B = 272 \: cm^2}}$

Now, we know that :-

$\underline{\boxed{\sf Volume \: of \: a \: cuboid = L \times B \times H}}$

Where,

L = Length.
B = Breadth.
H = Height.

Here,

Length × Breadth = 272 cm².
Volume = 1360 cm².

Let the height be h.

Substituting the given VALUES in this formula,

$\rm 1360 = 272 \times h$

Multiplying 272 with h,

$\rm 1360 = 272h$

Transposing 272 from RHS to LHS, changing it's sign,

$\rm \dfrac{1360}{272} = h$

DIVIDING 1360 by 272,

$\overline{\boxed{\rm 5 \: cm = h}}$

________________________________

Hence, the height of the cuboid is 5 cm.

Answer» LET the NUMBERS be X, X+1 (X+X+1)² = 20 (2X + 1)² = 20 4X² + 1 + 4X = 20 4X² + 4X = 19 4(X² + X) = 19 X² + X = 19/4 X² + X = 4.75 X(X+ 1) = 4.75 so, X = √(4.75/X)

15.

Sum of the square of the two consecative natural number is 20

Answer»

LET the NUMBERS be X, X+1

(X+X+1)² = 20

(2X + 1)² = 20

4X² + 1 + 4X = 20

4X² + 4X = 19

4(X² + X) = 19

X² + X = 19/4

X² + X = 4.75

X(X+ 1) = 4.75

so, X = √(4.75/X)

It implies, E is the midpoint of AC.

12. If A (1,-2), B (-2.3) and C (2.-5) are the vertices of AABC, then the equation of the median BE is(a) 7x + 13y + 47 = 0 (b) 13x + 7y + 5 = 0(c) 7x – 13y + 5 = 0 (d) none of these

Answer»

GIVEN :-

The vertices of triangle ABC as

A (1, -2)

B (-2, 3)

C (2, -5)

To Find :-

Equation of median BE

Solution :-

We KNOW,

Median BE divides the opposite side AC in to two equal parts.

It implies, E is the midpoint of AC.

Coordinates of A = (1, - 2)

Coordinates of C = (2, - 5)

Using midpoint Formula,

${\underline{\boxed{\rm \: (x,y) = \bigg({ \dfrac{x_1 + x_2}{2} \; ,\; \dfrac{y_1 + y_2}{2} \bigg) \quad}}}}$

Here,

• x₁ = 1

• x₂ = 2

• y₁ = - 2

• y₂ = - 5

Hence, Coordinates of E is evaluated as

$\rm :\longmapsto\:{\rm \: Coordinates \: of \: E = \bigg({ \dfrac{1 +2}{2} \; ,\; \dfrac{ - 2 - 5}{2} \bigg) \quad}}$

${\underline{\boxed{\rm \: Coordinates \: of \: E = \bigg({\dfrac{3}{2} \; ,\; \dfrac{ -7}{2} \bigg) \quad}}}}$

Now,

We know,

Equation of line passing through 2 points is given by

$\rm :\longmapsto\:\bf \:y - y_1 = \dfrac{y_2-y_1}{x_2-x_1} (x-x_1)$

Now,

$\rm :\longmapsto\:{\rm \: Coordinates \: of \: E = \bigg({\dfrac{3}{2} \; ,\; \dfrac{ -7}{2} \bigg) \quad}}$

$\rm :\longmapsto\:Coordinates \: of \: B = ( - 2, \: 3)$

Here,

$\rm :\longmapsto\:x_1 = - 2,y_1 = 3,x_2= \dfrac{3}{2} ,y_2= \dfrac{ - 7}{2}$

Hence, Equation of line BE is

$\rm :\longmapsto\:\:y - 3 = \dfrac{\dfrac{ - 7}{2} - 3}{\dfrac{3}{2} + 2 } (x + 2)$

$\rm :\longmapsto\:\:y - 3 = \dfrac{\dfrac{ - 7 - 6}{2}}{\dfrac{3 + 4}{2}} (x + 2)$

$\rm :\longmapsto\:\:y - 3 = \dfrac{ - 13}{7} (x + 2)$

$\rm :\longmapsto\:7y - 21 = - 13x - 26$

$\bf\implies \:13x + 7y + 5 = 0$

$\large{\boxed{\boxed{\bf{Option \: (b) \: is \: correct}}}}$

Additional Information :-

Different forms of equations of a STRAIGHT line

1. Equations of horizontal and vertical lines

Equation of the lines which are horizontal or parallel to the X-axis is y = a, where a is the y – coordinate of the points on the line.

Similarly, equation of a straight line which is vertical or parallel to Y-axis is x = a, where a is the x-coordinate of the points on the line

2. Point-slope form equation of line

Consider a non-vertical line L whose slope is m, A(x,y) be an arbitrary point on the line and P(a, b) be the fixed point on the same line. Equation of line is given by y - b = m(x - a)

3. Slope-intercept form equation of line

Consider a line whose slope is m which CUTS the Y-axis at a distance ‘a’ from the ORIGIN. Then the distance a is called the y– intercept of the line. The point at which the line cuts y-axis will be (0,a). Then equation of line is given by y = mx + a.

4. Intercept Form of Line

Consider a line L having x– intercept a and y– intercept b, then the line passes through X– axis at (a,0) and Y– axis at (0,b). Equation of line is given by x/a + y/b = 1.

5. Normal form of Line

Consider a perpendicular from the origin having length p to line L and it makes an angle β with the positive X-axis. Then, the equation of line is given by x cosβ + y sinβ = p.
