Answer:
(a) -7 , - 9 , - 11
(b) Arithmetic sequence
(c) There is a common difference of -2
(d) -53
Step-by-step explanation:
(a) To find the next three terms , we must firs check if it is arithmetic sequence or a geometric sequence . For it to be an arithmetic sequence , there must be a common difference :
check :
-3 - (-1) = -5 - (-3) = -7 - (-5) = -2
This means that there is a common difference of -2 , which means it is an arithmetic sequence.
The next 3 terms we are to find are: 5th term , 6th term and 7th term.
= a + 4d
= - 1 + 4 ( -2 )
= -1 - 8
= - 9
6th term = a +5d
= -1 + 5(-2)
= -1 - 10
= - 11
= a + 6d
= -1 + 6 (-2)
= -1 - 12
= -13
Therefore : the next 3 terms are : -9 , -11 , - 13
(b) it is an arithmetic sequence because there is a common difference which is -2
(c) Because of the existence of common difference
(d) 
= a + 26d
= -1 + 26 ( -2 )
= -1 - 52
= - 53
Answer:
approximately 9 weeks
Step-by-step explanation:
I can't really show the work on here, 1,000,000÷15,000= 66. (a whole lot of numbers, but only 66 is important). There is 7 days in a week, so 66 days ÷7 equals 9.(again a whole lot of useless numbers).

Answer: </h3>
approximately 36.633 cm if you use pi = 3.14
approximately 36.6519 cm if you use the calculator's stored value of pi
Work Shown:
L = arc length, r = radius, x = central angle in degrees
L = (x/360)*2*pi*r
L = (300/360)*2*pi*7
L = (35/3)pi .... exact arc length in terms of pi
L = (35/3)*3.14
L = 36.633 .... approximate arc length
Keep in mind that I used pi = 3.14 which isn't that great an approximation for pi. If you want to use more digits of pi, then use your calculator's built in version of it to get (35/3)*pi = 36.6519; of course it will depend on which option your teacher prefers.
Answer:
1306.90≅ 1307 rounded to the nearest tens
Step-by-step explanation:
r= radius = 13 cm
l is the slant height =19 cm
surface area of the cone= area of the circle + area of the curved of the cone
SA=πrl +πr²
SA=π(13)(19) +169π
SA= 247π +169π= 416π=1306.90≅ 1307 rounded to the nearest tens
