5.	The radius of circle OB is 26 cm OP 10 cm find AB ...
Answer» ANSWER: Step-by-step explanation: radius of circle,OB = 26 cm OP = 10 cm, we need to FIND AB $AB^{2}$ = $OB^{2} - BC^{2}$ = 26^2 - 10^2 = 676 - 100 AB = $\sqrt{576}$ AB = 24 cm is the answer

5.

The radius of circle OB is 26 cm OP 10 cm find AB ...

Answer»

ANSWER:

Step-by-step explanation:

radius of circle,OB = 26 cm

OP = 10 cm,

we need to FIND AB

$AB^{2}$ = $OB^{2} - BC^{2}$

= 26^2 - 10^2

= 676 - 100

AB = $\sqrt{576}$

AB = 24 cm is the answer

15.	the length of a rectangle is a three time of its breadth if the area of the rectangle is 432 CM square then find the perimeter
Answer» Answer: 96 centimeters. Step-by-step explanation: Let the breadth of the RECTANGLE be N. LENGTH = 3n Area of the given rectangle = 432 cm² Area = length x breadth 432=3n x n 432=3 x n x n 432/3=n² n²=144 n=√144 n=12 cm. Breadth = 12 cm Length=3 x 12 = 36 cm Perimeter of a rectangle = 2(l+b) =2(36+12) =2 x 48 =96 cm.

15.

the length of a rectangle is a three time of its breadth if the area of the rectangle is 432 CM square then find the perimeter

Answer»

Answer:

96 centimeters.

Step-by-step explanation:

Let the breadth of the RECTANGLE be N.

LENGTH = 3n

Area of the given rectangle = 432 cm²

Area = length x breadth

432=3n x n

432=3 x n x n

432/3=n²

n²=144

n=√144

n=12 cm.

Breadth = 12 cm

Length=3 x 12 = 36 cm

Perimeter of a rectangle = 2(l+b)

=2(36+12)

=2 x 48

=96 cm.

24.	Convert 20gm of water into mole
Answer» ANSWER: MOLAR mass of H = 1 Molar mass of O = 16 Molar mass of C = 12 Molar mass of Water = H20 = 2*1+16 = 18 G/mol So, 1 mole of water weighs = 18 g which implies, 18g of water = 1 mole THerefore, 20g of water = 20/18 = 1.11 mole

24.

Convert 20gm of water into mole

Answer»

ANSWER:

MOLAR mass of H = 1

Molar mass of O = 16

Molar mass of C = 12

Molar mass of Water = H20 = 2*1+16 = 18 G/mol

So, 1 mole of water weighs = 18 g

which implies, 18g of water = 1 mole

THerefore, 20g of water = 20/18 = 1.11 mole

Answer» $\dfrac{1+\cos \theta}{\sin \theta} -\dfrac{\sin \theta}{1+\cos \theta} =2\cot \theta$ , proved Step-by-step explanation: To prove that, $\dfrac{1+\cos \theta}{\sin \theta} -\dfrac{\sin \theta}{1+\cos \theta} =2\cot \theta$ L.H.S. = $\dfrac{1+\cos \theta}{\sin \theta} -\dfrac{\sin \theta}{1+\cos \theta}$ TAKING LCM of DENOMINATOR part, we GET $=\dfrac{(1+\cos \theta)^2-\sin^2 \theta}{\sin \theta(1+\cos \theta)}$ Using the algebraic identity, $(a+b)^{2} =a^{2} +2ab+b^2$ $=\dfrac{1+\cos^2 \theta+2\cos \theta-\sin^2 \theta}{\sin \theta(1+\cos \theta)}$ Using the TRIGONOMETRIC identity, $\sin^2 A=1-\cos^2 A$ $=\dfrac{1+\cos^2 \theta+2\cos \theta-(1-\cos^2 \theta)}{\sin \theta(1+\cos \theta)}$ $=\dfrac{1+\cos^2 \theta+2\cos \theta-1+\cos^2 \theta}{\sin \theta(1+\cos \theta)}$ $=\dfrac{2\cos^2 \theta+2\cos \theta}{\sin \theta(1+\cos \theta)}$ $=\dfrac{2\cos \theta(\cos \theta+1)}{\sin \theta(1+\cos \theta)}$ $=\dfrac{2\cos \theta}{\sin \theta}$ = $2\cot \theta$ = R.H.S., proved. Thus, $\dfrac{1+\cos \theta}{\sin \theta} -\dfrac{\sin \theta}{1+\cos \theta} =2\cot \theta$ , proved

Prove that1 + costheta/sintheta-sintheta/1+costheta=2cot theta

Answer»

$\dfrac{1+\cos \theta}{\sin \theta} -\dfrac{\sin \theta}{1+\cos \theta} =2\cot \theta$ , proved

Step-by-step explanation:

To prove that, $\dfrac{1+\cos \theta}{\sin \theta} -\dfrac{\sin \theta}{1+\cos \theta} =2\cot \theta$

L.H.S. = $\dfrac{1+\cos \theta}{\sin \theta} -\dfrac{\sin \theta}{1+\cos \theta}$

TAKING LCM of DENOMINATOR part, we GET

$=\dfrac{(1+\cos \theta)^2-\sin^2 \theta}{\sin \theta(1+\cos \theta)}$

Using the algebraic identity,

$(a+b)^{2} =a^{2} +2ab+b^2$

$=\dfrac{1+\cos^2 \theta+2\cos \theta-\sin^2 \theta}{\sin \theta(1+\cos \theta)}$

Using the TRIGONOMETRIC identity,

$\sin^2 A=1-\cos^2 A$

$=\dfrac{1+\cos^2 \theta+2\cos \theta-(1-\cos^2 \theta)}{\sin \theta(1+\cos \theta)}$

$=\dfrac{1+\cos^2 \theta+2\cos \theta-1+\cos^2 \theta}{\sin \theta(1+\cos \theta)}$

$=\dfrac{2\cos^2 \theta+2\cos \theta}{\sin \theta(1+\cos \theta)}$

$=\dfrac{2\cos \theta(\cos \theta+1)}{\sin \theta(1+\cos \theta)}$

$=\dfrac{2\cos \theta}{\sin \theta}$

= $2\cot \theta$

= R.H.S., proved.

Thus, $\dfrac{1+\cos \theta}{\sin \theta} -\dfrac{\sin \theta}{1+\cos \theta} =2\cot \theta$ , proved

43.	ImA 20 m deep well with diamt am isdog and the fourth from digging iseventy spread out to form a platform88m x 14 m. find the height of thePlat foom
Answer» Answer: magine two baseballs are being thrown at you. One is traveling at 50 mph and the other at 150 mph. Even if you somehow catch that 150 mph ball, it might knock you off your FEET. It will take more effort on your part to stop the 150 mph ball than the 50 mph one. So it stands to reason that velocity is a very IMPORTANT ASPECT of momentum. However, that's not all there is to momentum. Now imagine two balls being thrown at you at 50 mph. One is a baseball and the other is a bowling ball. You probably aren't going to want to try to stop the bowling ball. It's going to keep traveling even after it hits you. Both balls are traveling at the same velocity, so what makes the bowling ball so much harder to stop? It's because it is heavier. It has more mass. So the other important aspect of momentum is mass. In physics, we define momentum mathematically as the multiplication of mass and velocity as seen in this equation: p = m * v p = momentum m = mass v = velocity As far as momentum's units go, we have no SPECIAL symbol used just for momentum. Instead, it is simply the combination of mass's STANDARD unit of kilograms (kg) and velocity's standard unit of meters per second (m/s). Momentum is measured in standard units of kilograms times meters per second (kg m/s).

A rectangular grassy plot is 112 m, long and 78 m broad. It has a gravel path 2.5 m wide all around it on the side. Find the area of the path and the cost of constructing it at rs 4.50 square metre.

Answer»

ANSWER:AREA of PLOT =length *breath=

=112*78

=8736

new length= 112+2.5=114.5

new breadth=78+2.5=80.5

area =length *breath=

=114.5*80.5=9217.25

area of path=9217.25-8736=481.25

cost of constructing = 481.25*4.50=2165.625
