Answer:

An = 5n-18

Step-by-step explanation:

hello :

note :    the n th term of an arithmetic sequence is :

An =A1+(n-1)d   ....a common difference is : d  and A1 the first term

in this exercice :   d = 2-(-3)=-3-(-8) =5      A1 =  -13

the n th term of an arithmetic sequence is :An =-13+(n-1)(5)

An = 5n -5 -13

An = 5n-18

Ivanshal [37]

Answer:

  • 1.25 hours or 1 hour and 15 minutes

Step-by-step explanation:

<em>Question</em>

  • <em>Lisa lit a candle with a height of 8 inches. When lit, this candle loses 10% of its original  height every hour. </em>
  • <em>Please complete the following sentence by writing the number in the blank.   Until the candle has been burning for at least _______ hours, the height of Jennifer's candle will be more than 7 inches.</em>

<u>Candle looses 10% of 8 inches, it equals:</u>

  • 8*0.1 = 0.8 inches an hour

<u>Let x be required time, then:</u>

  • 8 - 0.8x > 7
  • 0.8x <  8 - 7
  • 0.8x  < 1
  • x  < 1/0.8
  • x  <  1.25
  • or 1 hour 15 minutes

Question 1:
AnnyKZ [126]

Answer(1):

Given that h(y)=2y-7.

h(8) means  plug y=8 into h(y)=2y-7.

h(8)=2*8-7=16-7=9

Hence C) 9 is the final answer.


Answer 2:

(7/8) = (m/32)

to solve for m, we begin by cross multiply

8m=7*32

8m=224

m=28

Hence choice C) 28 is final answer.


Reflection symmetry occurs when a line is drawn to divide a shape in halves so that each half is a reflection of the other.


Rotational symmetry is to check if the given picture is symmetric after some rotation.


Answer 3:

Letter "E" will have

B) the letter has reflection symmetry only

So B) is correct.


Answer 4:

Which statement is true?

Letter "Z" will have

B) the letter has rotation symmetry only

Hence B) is correct.


Answer 5:

Letter "X" will have

A) the letter has both reflection and rotation symmetry

Hence A) is correct.
