Answer» In TRIANGLE BDC BD²= BC²+CD² BD² = 12² + 5² BD² = 144 +25 BD² = 169 BD = 13cm In Triangle ABC AB²= AC² + BC² 15² = AC² + 12² 225 = AC² + 144 AC² = 225 - 144 AC² = 81 AC = 9 We know that AC = AD + CD SO, 9 = AD + 5 AD = 9-5 AD = 4

11.

ABC is right angle triangle with ACB=90*, BC=12cm, AB=15cm, and CD=5cm.Find the lengths of AD.

Answer»

In TRIANGLE BDC

BD²= BC²+CD²

BD² = 12² + 5²

BD² = 144 +25

BD² = 169

BD = 13cm

In Triangle ABC

AB²= AC² + BC²

15² = AC² + 12²

225 = AC² + 144

AC² = 225 - 144

AC² = 81

AC = 9

We know that AC = AD + CD

SO,

9 = AD + 5

AD = 9-5

AD = 4

Answer»

Answer:

This implies that

x2+2ax=4x−4a−13

or

x2+2ax−4x+4a+13=0

or

x2+(2a−4)x+(4a+13)=0

Since the equation has just one solution INSTEAD of the usual two distinct solutions, then the two solutions MUST be same i.e. discriminant = 0.

Hence we get that

(2a−4)2=4⋅1⋅(4a+13)

or

4a2−16a+16=16a+52

or

4a2−32a−36=0

or

a2−8a−9=0

or

(a−9)(a+1)=0

So the VALUES of a are −1 and 9.

Answer» ANSWER:- Speed of bus is 70 km per HOUR. Speed of train is 300 km per hour. Train TRAVELS faster than the bus. ━━━━━━━━━━━━━━━━━━━━━━━━━━ GIVEN:- Distance travelled by the bus in 6 hours :- 420 km Distance covered by the train in 3 hours :- 900 km TO FIND:- Speed of the bus = ? Speed of the train = ? Which one of the two travel's faster = ? SOLUTION:- Formula to find speed ↴ $\bold{ \underline {\overline{ \boxed{S = \frac{D \: (Distance)}{T\: (Time)}}}}}$ Speed of the bus = S = D/T S = D/T = 420/6 420/6 = 70 km So, the speed of the bus is 70 km per hour. Speed of the train = S = D/T S = D/T = 900/3 900/3 = 100 km So, the speed of the train is 300 km per hour. So, together the bus covers 70 Km in 1 hour and the train covers 300 Km in 1 hour. TO COMPARE:- Speed of the bus and Speed of the train Speed of bus = 70 km Speed of train = 300 km So, 300 > 70 Speed of the bus is LESSER than the speed of the train. So, the train travels faster than the train. ━━━━━━━━━━━━━━━━━━━━━━━━━━

A bus travelled a distance of 420 km in 6 hours and a train covered a distance of 900 km in3 hours. Calculate their speed and tell which one of the two travels faster- bus or train?

Answer»

ANSWER:-

Speed of bus is 70 km per HOUR.
Speed of train is 300 km per hour.
Train TRAVELS faster than the bus.

━━━━━━━━━━━━━━━━━━━━━━━━━━

GIVEN:-

Distance travelled by the bus in 6 hours :- 420 km

Distance covered by the train in 3 hours :- 900 km

TO FIND:-

Speed of the bus = ?

Speed of the train = ?

Which one of the two travel's faster = ?

SOLUTION:-

Formula to find speed ↴

$\bold{ \underline {\overline{ \boxed{S = \frac{D \: (Distance)}{T\: (Time)}}}}}$

Speed of the bus = S = D/T

S = D/T = 420/6

420/6 = 70 km

So, the speed of the bus is 70 km per hour.

Speed of the train = S = D/T

S = D/T = 900/3

900/3 = 100 km

So, the speed of the train is 300 km per hour.

So, together the bus covers 70 Km in 1 hour and the train covers 300 Km in 1 hour.

TO COMPARE:-

Speed of the bus and Speed of the train

Speed of bus = 70 km

Speed of train = 300 km

So,

300 > 70

Speed of the bus is LESSER than the speed of the train.

So, the train travels faster than the train.

The curved surface area of a cylinder of height 20cm is 1760cm^2.finds its volume

Answer»

$\: \: \: \: \: \: \: \sf{height \: of \: cylinder} = 20cm$

$\: \: \: \: \: \sf{curved \: surface \: area \: = 1760 \: {cm}^{2} }$

$\: \: \: \: \: \: \: \: \red{ \boxed{ \sf{csa \: of \: cylinder = 2\pi rh}}}$

$\: \: : ⟹ \: \:\: \: \: \: \: \: \: \: \sf{2\pi rh = 1760}$

$\: \: \: \: \: \: : ⟹ \sf {2 \times \ \frac{22}{7} \times r \times 20 = 1760}$

$\: \: \: \: \: \: \: \: \: \: \: : ⟹ \sf{r = \frac{1760 \times 7}{2 \times 22 \times \times 20 } }$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: : ⟹ \sf{r = 14 \: cm}$

$\: \: \: \: \: \: \: \pink{ \boxed{ \sf{volume \: of \: cylinder = \pi r {}^{2} h}}}$

$\: \: \: \: \: \: : ⟹ \: \: \: \: \sf{ \frac{22}{7} \times 14 \times 14 \times 20}$
