What is the 87th term of the arithmetic sequence with this explicit formula

Mathematics
1 answer:
emmasim [6.3K]2 years ago
8 0

Answer:Step-by-step explanation:

If there is a sequence and if we are to find its 87th term we must have the general term formula for the sequence.

Normally for sequences which follow a pattern there will be a formula for nth term.

Example is arithmetic sequence nth term = a+(n-1)d where a is the I term and d the common difference.

Similarly for geometric sequence nth term

= is the nth term

Thus to find the 87th term, we must be able to find out the pattern of the sequence by which any term is related to its previous term

Either general term formula or recurring formula should be given to get the 87th term

Step-by-step explanation: is arithmetic sequence nth term = a+(n-1)d where a is the I term and d the common difference. Still stuck? Get 1-on-1 help from an expert tutor now.

james and his sister save money for a trip to the water park. james has saved half the amount of money as his sister has saved.
valina [46]

Answer:

money saved by james = 30/2 = 15

equation used

money with James  = 3/4 (money with sister)

x/2 + 30 =3/4( x + 30 )

Step-by-step explanation:

Let money saved by sister be x

given

James has saved half the amount of money as his sister has saved.

Money saved by James = x/2

Total money saved by both of them = x + x/2

If they both save 30 more

Then

money with sister = x + 30

money with james = x/2 + 30

given that If they both save 30 more, james will have saved 3/4 as much as her sister

thus,

money with james  = 3/4 (money with sister)

x/2 + 30 =3/4( x + 30 )

=> 4(x+30*2) /2 = 3x+90

=> 2x + 120 = 3x + 90

=> 3x-2x = 120-90

=> x = 30

Thus,

money saved by james = 30/2 = 15

equation used

money with james  = 3/4 (money with sister)

x/2 + 30 =3/4( x + 30 )

A cone has the diameter of 15 inches and is 27 inches tall what is the volume for the cone?
suter [353]

Answer:

the volume of a cone = 1589.625feet³

Step-by-step explanation:

given that the diameter of the cone = 15inches

radius = 15inches/2 = 7.5inches

height of the cone = 27 inches

volume of the cone = ?

recall that

the  formulae for finding the volume of a cone is given to be

= 1/3πr²h

the volume of a cone = πr² h/3

the volume of a cone = 3.14  × ( 7.5)² × 27/3

the volume of a cone = (3.14 x  56.25 x27)/3

the volume of a cone = 4768.875/3

the volume of a cone = 1589.625feet³
