There is typo error in the question. Here is the corrected question:

The explicit rule for an arithmetic sequence is a_n=8.7+(-1.4)(n-1). What is the value of the 47th term? Round to the nearest tenth, if necessary.

A. –55.7

B. –26.4

C. 45.6

D. 65.8

Answer:

-55.7

Step-by-step explanation:

Given:

The explicit rule for the given arithmetic sequence is:

a_n=8.7+(1.4)(n-1)

Now, the 47th term is nothing but the value of 'n' as 47.

Plug in the value of 'n' as 47 in the above rule and determine the 47th term represented by a_{47}. This gives,

a_{47}=8.7-1.4(47-1)\\a_{47}=8.7-1.4(46)\\a_{47}=8.7-64.4\\a_{47}=-55.7

Therefore, the 47th term of the given arithmetic sequence is -55.7. So, the first option is correct.

kykrilka [37]
If it reaches its maximum height a t=3 its velocity must be zero at t=3

dy/dx=0 at t=3

dA/dx=4x+12=24 at t=3 so this does not apply

dB/dx=-4x+12=0 at t=3 and B=13 at t=3 so B applies

dC/dx=-4x-12=-24 at t=3 so this does not apply

dD/dx=-4x-12=-24 at t=3 so this does not apply

dE/dx=-4x-12=-24 at t=3 so this does not apply

So only quadratic B: reaches a maximum height of 13 feet at 3 seconds.

An office opens at 9am and closes at 5.30pm with a lunch break of 30minutes. What is the ratio of lunch break to the total perio
Alex777 [14]

Answer:

1:17

Step-by-step explanation:

Find out how long it it between 5.30pm and 9am. This is 8 hours 30 minutes or 510 minutes.

Now, arrange them in the ratio of Lunch Break to Total office time

30:510. This can be simplified to 1:17

Please check if the question is worded correctly, just in case. Because ratio questions are usually based on a part and the remaining parts of the same thing, and not part to whole.

Anyway. The answer given if for the question you have typed.

Hope this helps.

djyliett [7]

Answer:

13

Step-by-step explanation:

If ABC is equilaterteral then all the angles must be equal and 60°

8x - 44 = 60 add 44 to both sides

8x = 104 divide both sides by 8

x = 13

Help with this question please ASAP!! :)
Ivan

Answer:

options 1, 3, and 6.

Step-by-step explanation:

on the diagram, ∠2 is in the area of line EA and EG. If you are reading it by letters, ∠GEA is equal to ∠2 because they are in the same area. The last option (6) being ∠AEG, the middle angle is E which is the same as ∠GEA and ∠2.

hope this helps!! :))
