6.	What is the distance between thepoints A (sintita-costita,0) B(0,sintita +costita)?
Answer» THETA is WRITTEN as A. Answer: Distance between ( sinA - cosA, 0 ) and ( 0 , sinA + cosA ) is √2. Step-by-step explanation: Using distance formula : Distance between any two points A( a,B ) and B( c, d ) is given by √{ ( a - c )^2 + ( b - d )^2 } . On the BASIS of this : = > Distance between the given points = > √{ ( sinA - cosA -0 )^2 + ( 0 - sinA - cosA ) } = > √{ sinA - cosA )^2 + ( - sinA - cosA )^2 } = > √{ sin^2 A + cos^2 A - 2sinAcosA + sin^2 A + cos^2 A + 2sinAcosA } = > √{ 2( sin^2 A + cos^2 A ) } = > √2( 1 ) = > √2 HENCE distance between ( sinA - cosA, 0 ) and ( 0 , sinA + cosA ) is √2.

What is the distance between thepoints A (sintita-costita,0) B(0,sintita +costita)?

Answer»

THETA is WRITTEN as A.

Answer:

Distance between ( sinA - cosA, 0 ) and ( 0 , sinA + cosA ) is √2.

Step-by-step explanation:

Using distance formula :

Distance between any two points A( a,B ) and B( c, d ) is given by √{ ( a - c )^2 + ( b - d )^2 } .

On the BASIS of this :

= > Distance between the given points

= > √{ ( sinA - cosA -0 )^2 + ( 0 - sinA - cosA ) }

= > √{ sinA - cosA )^2 + ( - sinA - cosA )^2 }

= > √{ sin^2 A + cos^2 A - 2sinAcosA + sin^2 A + cos^2 A + 2sinAcosA }

= > √{ 2( sin^2 A + cos^2 A ) }

= > √2( 1 )

= > √2

HENCE distance between ( sinA - cosA, 0 ) and ( 0 , sinA + cosA ) is √2.

Answer:

Q5. BY USING the FORMULA for even obs.

[n/2th obs.+(n/2+1)th obs.]/2

So accord. To question,

x–2+x=32

So,x=17.

Q6. Probablity will be 2/10= 1/5

Q9. The co.ordinates of the triangle will be, (0,0);(0,6);(6,0)

As x/6+y/6=1 (as we know that the denominator will be the required x and y co-ordinates.)

So AREA of the triangle,

1/2×6×6=18 sq.units.

The dripped water is collected in a cylindrical vessel.The outer diameter and uniform thickness of this vessel is 10 cm and 1 cm respectively. How many minutes will be required to fill the vessel completely if it's height is 70 cm?
Answer» Total minute to fill vessel = 109.95 minute. Given: Water drips from a tap at a rate of 4 drops every 3 seconds . Volume of one drop of water is 0.4 cubic cm. The outer diameter of this vessel is 10 cm. Uniform thickness of this vessel is 1 cm. Height of this vessel is 70 cm. Find: How many minutes will be required to fill the vessel completely. Explanation: Inside diameter of the vessel is 2 times less than thickens of the vessel because of both side thickness Inside diameter of the vessel = 10 - (2×1) =8 cm. Volume of vessel = $\frac{\pi }{4}$ ×(Inside diameter) ² × Height = $\frac{\pi }{4}$ × 8² × 70 =3518.58 cm³ 4 drops every 3 seconds and one drop =0.4 cm³ Therefore 4 drop = 4 × 0.4 = 1.6 cm³ for 3 second.

Water drips from a tap at a rate of 4 drops every 3 seconds .Volume of one drop of water is 0.4 cubic cm. The dripped water is collected in a cylindrical vessel.The outer diameter and uniform thickness of this vessel is 10 cm and 1 cm respectively. How many minutes will be required to fill the vessel completely if it's height is 70 cm?

Answer»

Total minute to fill vessel = 109.95 minute.

Given:

Water drips from a tap at a rate of 4 drops every 3 seconds .
Volume of one drop of water is 0.4 cubic cm.
The outer diameter of this vessel is 10 cm.
Uniform thickness of this vessel is 1 cm.
Height of this vessel is 70 cm.

Find:

How many minutes will be required to fill the vessel completely.

Explanation:

Inside diameter of the vessel is 2 times less than thickens of the vessel because of both side thickness
Inside diameter of the vessel = 10 - (2×1)

=8 cm.

Volume of vessel = $\frac{\pi }{4}$ ×(Inside diameter) ² × Height

= $\frac{\pi }{4}$ × 8² × 70

=3518.58 cm³

4 drops every 3 seconds and one drop =0.4 cm³
Therefore 4 drop = 4 × 0.4 = 1.6 cm³ for 3 second.
Therefore for 1 minutes total volume fill will be =1.6 × $\frac{60}{3}$

= 32 cm³

Total minute to fill vessel = $\frac{3518.58}{32}$

= 109.95 minute.

Determine whethermachino should be purchased ornot:(a) Should be purchased(b) Should not bo purchased(c) Can't say about purchase(d) None of the above
Answer» Answer: (a) Should be purchased Step-by-step explanation: this is because the BORROWING charge is 10% p.a. which means ₹5,000 each year and machine will contribute ₹12,000 each year so the PROFIT for each year is ₹12,000 - ₹5,000 = ₹7,000 hence TOTAL profit is ₹35,000

(a) Should be purchased

Step-by-step explanation:

this is because the BORROWING charge is 10% p.a. which means ₹5,000 each year
and machine will contribute ₹12,000 each year
so the PROFIT for each year is ₹12,000 - ₹5,000 = ₹7,000
hence TOTAL profit is ₹35,000

48.	A motor boat goes down the stream 30km and again returns to thestarting point in a total time of 4 hours and 30 minutes. If the speed of the stream is 5 kon/hr, then find the speed of the motor boat in still water.
Answer» $\bold{\underline{QUESTION}}$ A Motor boat goes downstream 30 km and again returns to the starting point in a total time of 4 hours and 30 minutes if the speed of the stream is 5 kilometre per hour then find the speed of motor boat in still water. $\bold{\underline{ANSWER}}$ Speed of motor boat in still water is 15 km/h. Step-by-step EXPLANATION: The speed of the boat in still water is 15 km/hr. Total time taken by the motorboat = 4 hrs 30 minutes = 4 ½ hr = (9/2) hrs The distance TRAVELLED by boat during downstream = 30 km The speed of the stream = 5 km/hr Let the speed of the boat in still water be “x” km/hr. So, The speed of the boat downstream = (x + 5) km/hr The speed of the boat upstream = (x - 5) km/hr and, Time taken to travel downstream = 30/(x+5) Time taken taken to travel upstream = 30/(x-5) Therefore, according to the question, we can write the eq. as, [30/(x+5)] + [30/(x-5)] = 9/2 ⇒ 30 [(x-5+x+5)/{(x-5)(x+5)}] = 9/2 ⇒ 30 [(2X) / (x² - 25)] = 9/2 ⇒ 10 [(2x) / (x² - 25)] = 3/2 ⇒ 40x = 3x² – 75 ⇒ 3x² – 40x – 75 = 0 ⇒ 3x² – 45x + 5X – 75 = 0 ⇒ 3x(x-15) + 5(x-15) = 0 ⇒ (x-15)(3x+5) = 0 ⇒ x = 15 or -5/3 Neglecting the negative value ⇒ x = 15 km/hr ← speed of the boat in still water ----------------------------------------------------------------------------------------- Also View: A man can row 4.5 km/hr in still water and he finds that it takes him twice as long to row up as to row down the river.

A motor boat goes down the stream 30km and again returns to thestarting point in a total time of 4 hours and 30 minutes. If the speed of the stream is 5 kon/hr, then find the speed of the motor boat in still water.

Answer»

$\bold{\underline{QUESTION}}$

A Motor boat goes downstream 30 km and again returns to the starting point in a total time of 4 hours and 30 minutes if the speed of the stream is 5 kilometre per hour then find the speed of motor boat in still water.

$\bold{\underline{ANSWER}}$

Speed of motor boat in still water is 15 km/h.

Step-by-step EXPLANATION:

The speed of the boat in still water is 15 km/hr.

Total time taken by the motorboat = 4 hrs 30 minutes = 4 ½ hr = (9/2) hrs

The distance TRAVELLED by boat during downstream = 30 km

The speed of the stream = 5 km/hr

Let the speed of the boat in still water be “x” km/hr.

So,

The speed of the boat downstream = (x + 5) km/hr

The speed of the boat upstream = (x - 5) km/hr

and,

Time taken to travel downstream = 30/(x+5)

Time taken taken to travel upstream = 30/(x-5)

Therefore, according to the question, we can write the eq. as,

[30/(x+5)] + [30/(x-5)] = 9/2

⇒ 30 [(x-5+x+5)/{(x-5)(x+5)}] = 9/2

⇒ 30 [(2X) / (x² - 25)] = 9/2

⇒ 10 [(2x) / (x² - 25)] = 3/2

⇒ 40x = 3x² – 75

⇒ 3x² – 40x – 75 = 0

⇒ 3x² – 45x + 5X – 75 = 0

⇒ 3x(x-15) + 5(x-15) = 0

⇒ (x-15)(3x+5) = 0

⇒ x = 15 or -5/3

Neglecting the negative value

⇒ x = 15 km/hr ← speed of the boat in still water

-----------------------------------------------------------------------------------------

A man can row 4.5 km/hr in still water and he finds that it takes him twice as long to row up as to row down the river. Find the rate of the stream.
