the taxi fare in a city is as follows for the first kilometre, the fare is Rs 8 and for the subsequent distance it is Rs 5/km. taking the distance covered as x km and the total fare is Rs y, write a linear equation for this information and draw it's graph.​

Answer»

ANSWER:

here is your ans

Step-by-step explanation:

Total distance covered = x km. (GIVEN)

         Fair for 1st kilometre = RS.8 (Given)

         Fair for rest distance = (x 1) 5 (Since, it is given that except for first kilometre, the fare for subsequent distance is Rs 5 per km)

               Total fair = 8 + (x 1) 5

         y = 8 + 5x 5 (Total fare is given to be y)

         y = 5x + 3

         5x y + 3 = 0  

This is the REQUIRED linear equation.

Reduce the equation x-v3y +8 = 0 to the normal form.​

Answer»
  • The zeros of a polynomial are the SOLUTIONS to the equation P(X) = 0, where p(x) represents the polynomial. If we graph this polynomial as y = p(x), then you can see that these are the VALUES of x where y = 0. In other words, they are the x-intercepts of the graph

Two buildings are facing each other on a road of widht 12 metres. From the top of the first building which is 10 metres high, the angle of elevation of the top of the second is found to be 60°. What is the height of the second building?​

Answer»

Answer:

hello

Let AB and CE are two buildings are facing each other on a road BD of width 12m as shown in figure. From the top of the FIRST BUILDING , which is 10m high, the angle of elevation of the top of the second building CD is found to be 60°.

Let E is the point on CD in such a way that AB = ED = 10cm

Let CE = x m

Now, ∆CAE,

tan∠CAE = CE/AE [ see figure ]

tan60° = x/12 [ ∵AE = BD = 12m ]

√3 = x/12

x = 12√3 m

Hence, HEIGHT of second building is (x + 10) = 12√3 + 10 = 12 × 1.7 + 10

= 20.4 + 10 = 30.4 m

Please solve fastfastest gets brainlest​

Answer»

The circle touches the SIDES BC, CA, AB of the right triangle ABC at D, E and F respectively.

Assume BC = a, CA = b and AB = c

Then AE = AF and BD = BF, CE = CD .

OE = OD = OF = r.

Here OEDC is a square then CE = CD = r. i.e., b – r = AF, a – r = BF or AB = c = AF + BF = b – r + a – r

∴ r = (a + b - c )/2

the taxi fare in a city is as follows for the first kilometre, the fare is Rs 8 and for the subsequent distance it is Rs 5/km. taking the distance covered as x km and the total fare is Rs y, write a linear equation for this information and draw it's graph​

Answer»

ANSWER:

Step-by-step explanation:

As we know for first kilometer the price it Rs 8.                 ....(i)

As the TOTAL distance is x hence the distance TRAVELED after the first kilometer is x-1.

Fare per km after the first kilometer is 5.

So fare of x-1 km = 5*(x-1)                                                    ....(II)

We know total fare is Y.

hence

Adding eq (i) and (ii) we get

Y=5(X-1)+8.

or

Y=5X+3.

If x²-2x+sin²a=0 then​

Answer»

Answer:

GIVEN :

2 x tan²60° + 3 x sin²30° = ( 27 cos²45° ) / 4 sin²60° )

In the attachment , I have given the trigonometric table .

From there we have :

TAN 60° = √3

sin 30° = 1/2

cos 45° = 1 /√2

sin 60° = √3 / 2

Hence we can write the above equation as :

2 x ( √3 )² + 3 x ( 1/2 )² = ( 27 × ( 1/√2 )² ) / ( 4 × ( √3/2 )² )

⇒ 2 x × 3 + 3 x × 1/4 = ( 27/2 / 3 )

⇒ 6 x + 3 x /4 = 9/2

⇒ 2 x + x/4 = 3/2

⇒ x ( 2 + 1/4 ) = 3/2

⇒ x ( 8 + 1 )/4 = 3/2

⇒ x × 9/4 = 3/2

⇒ x = 3/2 × 4/9

⇒ x = 2/3

The value of x is 2/3

↪ sin A = x , then sin²A is x² . sin²A is spelled as sin squared A .

↪ The ratios sin , cos , cot , tan , sec and cosec are all positive in the first quadrant .

↪ Thereby the ratios of ACUTE angles are positive .

↪ It means that ratios of trigonometry INVOLVING 0° - 90° are always positive .

Find the value of Lim x--> π sin (π-x)/ π (π-x)

Answer»

Step-by-step explanation:

LIM sin(π-X)/π(π-x)

x---→ π

Now put π-x = h

So, for x---→ π , h---→ 0

So we have

Lim sinh/πh

h---→0

{We KNOW that limh----→0 sinh/h = 1}

Therefore,

Lim 1/π

h--→0

=1/π

Final Answer : 1/π

Write the capacity of tank in cubic metersand express titreslength is 5m40cm , breadth 6cm20cm , depth 8m,50​

Answer»

Answer:

the CAPACITY of tank in CUBIC metre is 284.58 cubic metre . in litre is 28458 litre .

Step-by-step explanation:

length = 5m40cm

= 5m + 0.4m

= 5.4m

breadth = 6M + 20cm

= 6m + 0.2m

= 6.2m

height = 8m50cm

= 8M + 0.5m

= 8.5m

capacity of tank = vol. of tank

= l × b × h

= 5.4 × 6.2 × 8.5

= 284.58 cubic metre

capacity of tank in litre is 28458 litre

Yaman runs a factory. He makes 2 groups of workers. He observes that the first group with (a -1) workers has worked for (b+1) days and the second group with (b+2) workers has worked for (a-1) days. The productivity ratio of group 1 to group 2 comes out to be 9/10. Can you calculate b.​

Answer»

•Yaman runs a factory.

•He makes 2 groups of WORKERS.

•He observes that the first group with (a -1) workers has worked for (b+1) day.

•The second group with (b+2) workers has worked for (a-1) DAYS.

•The productivity RATIO of group 1 to group 2 comes out to be 9/10.

•Productivity ratio of group 1 is (a-1)*(b+1)

•Productivity ratio of group 2 is (b+2)*(a-1)

•Therefore [(a-1)*(b+1)]/[(b+2)*(a-1)] = (b+1)/(b+2) = 9/10
