Step-by-step explanation:

Given that,

Mass of Ella is 56 kg and mass of Tyrone is 68 kg.

Position of Ella is 1.5 m on the ramp.

Potential energy of an object is given by :

P = mgh

It is directly proportional to the position of an object.

If Tyrone stands at the top of ramp at more height than Ella, it will have more potential energy. Hence, the correct option is (d) "If Tyrone stands at the top of a 2 m high ramp, his potential energy will be greater than Ella's."

A car owner buys diesel at rs 7.50, rs 8, rs 8.50 per litre for three successive years. what approximately is the average cost p
alex41 [277]

Answer:

Average cost per litre of diesel = rs 8.00

Step-by-step explanation:

Amount spent on diesel each year = rs 4000

Price of a litre of diesel in the first year = rs 7.50

Price of a litre of diesel in the second year = rs 8.00

Price of a litre of diesel in the third year = rs 8.50

Average cost per litre of diesel = \frac{p_{1} + p_{2} + p_{3}  }{n}

where n is the number of years.

Average cost per litre of diesel  =  \frac{7.5 + 8.00 + 8.50}{3}

                                                     = \frac{24}{3}

                                                     = 8

Average cost per litre of diesel is rs 8.00

So that he buys an average of 500 (i.e \frac{4000}{8}) litres every year.

What is the explicit formula for this geometric sequence with recursive formula
Nonamiya [84]

C

generate the first few terms using the recursive formula

a_{2} = - 7 × \frac{1}{3} = - \frac{7}{3}

a_{3} = - \frac{7}{3} × \frac{1}{3} = - \frac{7}{9}

a_{4} = - \frac{7}{9} × \frac{1}{3} = - \frac{7}{27}

r = a_{2} / a_{1} = \frac{1}{3}


the n th term formula (explicit ) for a geometric sequence is

a_{n} = a_{1}r^{n-1} = - 7(\frac{1}{3})^(n - 1)

One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg ha
anastassius [24]
Solutions

To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c². 

Given 

One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg has a length of 10x yards.

First leg (24 yards) would be α 

Second leg would be β

Hypotenuse (74 yards) would be c

Now we have points α β c.  

a² (24) + β² ( x ) = c² (74) 

Calculations 

c² = α² + β²

74² = 24²+ β² 

<span>5476 = 576 + </span>β² 

5476 - 576 = β²
<span> </span>
<span>4900 = </span>β² 

→√4900 
<span> </span>
β<span> = 70 yards 
</span>
<span>70 = 10x 
</span>
<span>x = 70</span>÷<span>10 = 7 yards  
</span>
The second leg = 7 yards
