a.The formula that describe the sequence or progression is a+(7-7n)
b. 2nd term = -10 , 3rd term = 10, 4th term = -10 and 5th term = 10
What is arithmetic and geometric progression?Geometric Progression (GP) is a type of sequence where each succeeding term is produced by multiplying each preceding term by a fixed number, which is called a common ratio.
Arithmetic Progression (AP) is a sequence of numbers in order, in which the difference between any two consecutive numbers is a constant value. It is also called Arithmetic Sequence.
The nth term of an arithmetic progression is given as a(n)= a + (n − 1) × d
In geometric progression the nth term is given as a(n)= ar^(n-1)
where a is the first term
therefore if a = 12 and d is - 7
the formula for the arithmetic progression =
a(n) = 12+(n-1) -7 = 12+( 7-7n)
If the first term of a GP is 10 with common ratio of -1
then the second term = 10×-1 = -10
third term = -10×-1 = 10
fourth term = 10×-1 = -10
fifth term = -10× -1 = 10

Answer:
min: $65
per hour: $7.50
Step-by-step explanation:
The equation tells you Monica expects her pay to be $65 when she works 0 hours. That will be the minimum.
y = 7.5·0 +65 = 65 . . . for 0 hours
It also tells you the pay is expected to go up by $7.50 if she works 1 hour. That will be her hourly rate.
y = 7.5·1 +65 = 72.5 . . . for 1 hour; an increase of 7.50 over the minimum.
Minimum pay: $65
plus $7.50 per hour

14. x=1, x=−9
x^2 + 8x + 20 = 29
x^2 + 8x + 4^2 = 9 + 4^2
(x + 4)^2 = 25
x + 4 = ± 5
15. x = -1/2, x = -3/2
4x^2+8x+3=0
x = -8 ± √8^2-4x4x3/2x4
x = -8 ± √64-4x4x3/2x4
x = -8 ± √64-16x3/2x4
x = -8 ± √64-48/2x4
x = -8 ± √16/2x4
x = -8 ± √4/2x4
x = -8 ± √4/8
x = -4/8

Which expression represents the lateral surface area of the cone?
8 cm
6 cm
10 cm
LA-xi
0 (x)(3 cm)(10 cm)
O (*)(6 cm)(8 cm)
O (*)(6 cm)(10 cm)
N
Answer:
π(6 cm) (10 cm)
Step-by-step explanation:
As we know that
The formula to calculate the lateral surface area of the cone is πrl
where
r denotes the radius i.e. 6 cm
l denotes the length i.e. 10 cm
So based on the above information
The expression that shows the lateral surface area of the cone is
π(6 cm) (10 cm)
Therefore the third option is correct
Hence, the same would be relevant

About how much cardboard is needed to make the inner tube for a roll of paper if the tube has a radius of 2.25 cm and is 24 cm long?
382 cm
339 cm?
679 cm
371 cm
Step-by-step explanation:
Cardboard needed to make tube =
Circumference of Circle base (remember the base is hollow therefore there is no area needed.) x Length of Tube
given r = 2.25cm
L = 24cm
Cardboard needed =
[tex]2\pi \: rl = \\ 2\pi(2.25)(24) \\ = 2\pi(54) \\ = 108\pi {cm}^{2} \\ = 339 {cm}^{2} [/tex]
The cardboard is needed to make the inner tube for a roll of paper if the tube has a radius of 2.25 cm and is 24 cm long will be 339 cm². Option B is correct.
What is surface area ?The total land area of all the faces of a three-dimensional object is its surface area. When we wish to wrap something in real life, we employ the notion of surface areas of distinct things.
The cardboard is needed to make the inner tube for a roll of paper is found as;
Surface area of cardboard;
A=2πRL
A=2×3.14×(2.25)(24)
A=339 cm².
Hence,the cardboard is needed to make the inner tube for a roll of paper will be, 339 cm².

What is the answer for x+6x
Answer:
The answer is 7x
Step-by-step explanation:
The x is the coefficent and every x has a coefficent even if it doesn't have number because the coefficent represent how many x's there are so it is one x plus 6 x and that equal seven x. The x can be anything but one of something plus 6 equals 7.

Answer:
Step-by-step explanation:
well just go throught the factors as far as you can ik from my personal mindset that 14*14= 196 so if i go bk and calculate 13*13=169 which means its gonna be in between 13 and 14. so to figure this out we have to write it out. so we can try 13.5*13.5=182.25 so we have to go higher 13.89*13.89=192.9321 which means it has to be 13.89 rounded to the nearest hundreth.

Find the surface area of the
rectangular prism.
4 ft.
12 ft.
9 ft.
[? ] sq ft.
Answer:
384Step-by-step explanation:
Given,
Dimensions of the rectangular prism = 9ft, 12ft and 4ft
Therefore,
Surface area of the rectangular prism
= 2( lb + bh + lh)
[tex] = 2(12 \times 9 + 9 \times 4 + 12 \times 4) {ft}^{2} [/tex]
[tex] = 2(108 + 36 + 48) {ft}^{2} [/tex]
[tex] = 2 \times 192 {ft}^{2} [/tex]
[tex] = 384 {ft}^{2} [/tex]
Hence,
Surface area of rectangular prism is 384 sq. ft (Ans)
