Answer:

Option (2)

Step-by-step explanation:

In an arithmetic progression,

a_1,a_2,a_3.........a_{n-1},a_n

First term of the progression,

a = a_1

Common difference 'd' = (a_2-a_1)

Recursive formula for the sequence,

a = a_1

a_n=a_{n-1}+d

By applying these rules in the recursive formula,

a_1=\frac{4}{5}

a_n=a_{n-1}+\frac{3}{2}

Common difference 'd' = \frac{3}{2}

Therefore, Option (2) will be the answer.

Elan Coil [88]

Answer:

14 cm

Step-by-step explanation:

Given:

A mug can hold 13.46 oz of coffee.

The radius of the mug is 3 cm.

Given that 1 cm^{3} equals 0.034 oz.

Question asked:

What is the height of the mug to the nearest centimeter ?

Solution:

Given that 1 cm^{3} equals 0.034 oz.

By unitary method:

0.034 oz = 1 cm^{3}

1 oz = \frac{1}{0.034}

13.46 oz = \frac{1}{0.034}\times13.46 =395.88 \ cm^{3}

A mug can hold 13.46 oz of coffee means volume of cylinder is given which is 395.88 cm^{3}. Now we can find the height of the mug by using volume of cylinder formula:

volume of cylinder = \pi r^{2} h

                   395.88=\frac{22}{7} \times3\times3\times \ h\\395.88=\frac{198 \ h}{7}

By cross multiplication:

                 395.88\times 7 =198\ h\\2771.16= 198\ h

By dividing both side by 198

h = 13.99 cm

Therefore,  height of the mug to the nearest centimeter is 14 cm.
