Answer:
7n + 1
Step-by-step explanation:
the general formula for figuring out the formula of a sequence is a + (n - 1)d, where a = the first term and d = the common difference
The question tells u that the first term is 8 and the common difference is 7
Knowing this, you can substitute those values into the formula and simplify:
a + (n - 1)d
= 8 + (n - 1)*7
= 8 + (7n -7)
= 8 + 7n - 7
= 7n - 7 + 8
= 7n + 1
and there's your explicit formula! hope this helped!

1. -1, 3, 4
2. -3, 0, 0, 5
3. -2 multiplicity 3
4. (x+3)^2(x+1)
Answer:
Step-by-step explanation:
(x+1)(x-3)(x-4) = (x+1)(x²-7x+12) = x³-6x²+5x+12
:::::
(x+3)(x-0)(x-0)(x-5) = (x+3)(x²)(x-5) = (x²-2x-15)x² = x⁴-2x³-15x²
:::::
(x+2)³ = x³ + 3·x²·2 + 3·x·2² + 2³ = x³ + 6x² + 12x + 8
:::::
(x+3)²(x+1) = (x²+6x+9)(x+1) = x³ + 7x² + 15x + 9

The length of a rectangle is 3 times as big as the width. If beth increases each dimension by 4, write an expression to represent the new area, a, of the rectangle.
Answer: See explanation
Step-by-step explanation:
Let the width of the rectangle be x.
The length of a rectangle is 3 times as big as the width. Length = 3x
New width = x + 4
New length = 3x + 4
The new area will be:
a = (3x + 4)(x + 4)
a = 3x² + 12x + 4x + 16
a = 3x² + 16x + 16

The sum of 6 times a number and 8 times another number is 12. The difference of those numbers is 9. What are the two numbers
Answer:
(x,y): (6 , -3) or (-30/7 , 33/7)
Step-by-step explanation:
6x + 8y = 12
x = y + 9 or y = x+ 9
if x = y+9
6*(y+9) + 8y = 12
14y = -42
y = -3 and x = 6
if y = x+9
6x + 8*(x+9) = 12
14x = -60
x = -30/7 and y = 33/7

Peggy takes 2.5 hours to deliver 328 magazines. What is the rate per hour she is delivering the magazines
Answer: 131 magazines per hour
Step-by-step explanation:
Peggy delivered 328 magazines in 2.5 hours.
To find out the rate at which she delivered these magazines, divide the number of magazines by the time taken to deliver them:
= Magazines / Time in hours
= 328 / 2.5
= 131 magazines per hour
The image shown is an object formed from a cylinder and spherical hemisphere. The radius of the base is 7 cm and the height of the cylinder is 10 cm
(π = 22/7). The volume of the object is ....
A. 2258,67 cm3
B. 2618,33 cm3
C. 2926,67 cm3
D. 2977,33 cm3
Answer:
Volume = 2,258.67 cm³
Step-by-step explanation:
Volume of the object = volume of hemisphere + volume of cylinder
= ⅔πr³ +πr²h
Where,
π = 22/7
r = 7 cm
h = 10 cm
Volume = (⅔*22/7*7³) + (22/7*7²*10)
Volume = 2,258.67 cm³

The ratio x:10 is equilvalent to 9:6. What is the value of x
Answer: x=20/3=6.67
Step-by-step explanation:
To solve proportions, the most useful way is to use [cross multiplication], where we not multiply horizontally but as diagonally.
-----------------------------------------------------------------------------
Given
x:10=9:6
Cross Multiply
9·x=6·10
9x=60
Divide 9 on both sides
9x/9=60/9
x=20/3=6.67
Hope this helps!! :)

A rectangular prism is 3 inches long, 5 inches wide, and has a height of 6 inches. What is its surface area?
63 in 2
90 in 2
120 in 2
126 in 2
Answer:
D) 126 in²
Step-by-step explanation:
A rectangular prism is 3 inches long, 5 inches wide, and has a height of 6 inches. What is its surface area?
The formula for the surface area of a rectangular prism =
A=2(wl+hl+hw)
Where
W= Width = 5in
H = Height = 6 in
l = Length = 3 in
Surface area =
2(5 × 3 + 6 × 3 + 5 × 6) square inches
2(15 + 18 + 30) square inches
2(63) square inches
= 126 square inches (in²)

Answer:
Radius is 3.5 cm
Diameter is 7 cm
Step-by-step explanation:
Radius is half the diameter
They give you the diameter at 7 cm
Then you have to half that to get 3.5 cm as the radius
Answer:
The answers are the diameter is 7 because whatever the line across is it's the diameter and the radios is half of what the diameter is so whatever is half of 7 is your radios.
Step-by-step explanation:
Diameter: 7
Radios: 3.5 or 3 1/2
Urgent please help..
Answer:
answer would be (1,-1)
Step-by-step explanation:
Dialation means to multiply, so u would multiply the point where D is so in the graph it shows D is on 2, -2 so you would multiply 2 by 1/2 and -2 by 1/2 which would give you (1, -1)
Find the volume of the prism. Round your answer to the nearest tenth.
for brainlist
Answer:
d. V = 668.2 ft³
Step-by-step explanation:
[tex]V = \frac{1}{2}bhl\\V = \frac{1}{2}(8.6)(8.4)(18.5)\\V = 668.2ft^{3}[/tex]
Answer:
[tex]\boxed {\boxed {\sf D. \ V \approx 668.2 \ ft^3}}[/tex]
Step-by-step explanation:
The volume of a triangular prism is found using this formula:
[tex]V=\frac{1}{2} bhl[/tex]
For this prism, the base is 8.6 feet, the height is 8.4 feet, and the length is 18.5 feet.
[tex]b= 8.6 \ ft \\h= 8.4 \ ft \\l= 18.5 \ ft[/tex]
Substitute the values into the formula.
[tex]V= \frac{1}{2} (8.6 \ ft) (8.4 \ ft) ( 18.5 \ ft)[/tex]
Multiply the first two numbers in parentheses.
[tex]V= \frac{1}{2} (72.24 \ ft^2) ( 18.5 \ ft)[/tex]
Multiply again.
[tex]V= \frac{ 1}{2} (1336.44 \ ft^3)[/tex]
Multiply by 1/2 or divide by 2.
[tex]V= 668.22 \ ft^3[/tex]
Round to the nearest tenth. The 2 in the hundredth place tells us to leave the 2 in the tenth place.
[tex]V \approx 668.2 \ ft^3[/tex]
The volume is about 668.2 cubic feet.

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 11 feet cubed.
A sphere with height h and radius r. A cylinder with height h and radius r.
Which equation gives the volume of the sphere?
V = four-thirds (11) pi
V = two-thirds (11) pi
V = four-thirds (11)
V = two-thirds (11)
9514 1404 393
Answer:
V = (2/3)(11)
Step-by-step explanation:
The given cylinder has a height of 2r, so its volume is ...
V = πr²(2r) = 2πr³
The volume of a sphere is given by ...
V = 4/3πr³
Then the ratio of the volume of the sphere to the volume of the cylinder is ...
(4/3πr³)/(2πr³) = (4/3)/2 = 2/3
So, the volume of the sphere is 2/3 times the volume of the cylinder:
V = (2/3)(11)
Answer:
answer is d

Bob and Chris share money in the ratio 2:3
Bob receives £8
Work out how much Chris receives
Step-by-step explanation:
total ratio is 5
first find the total amount
bob's ratio is 2/5
so 2/5 ×total amount=8 pounds
0.4 ×total amount=8 pounds
total amount=8/0.4=20 pounds
so chris receives: 20-8=12 pounds
The ground temperature at airport is 12 degrees. The temperature decreases by 5.2 degrees for every mile above ground. What would be the temperature outside of plane 3 miles above ground
Answer:
-3.6 degrees
Step-by-step explanation:
Since we need to find the temperature that is 3 miles above ground we first need to multiply the distance above ground by the decrease in temperature per mile.
3 * 5.2 = 15.6
Now that we have the total decrease in temperature at that altitude we subtract it from the temperature at ground level. This gives us the final temperature at 3 miles above the ground.
12 - 15.6 = -3.6
Finally, we can see that the temperature is -3.6 degrees

Step-by-step explanation:
We need to find the value of the given expression :
30³÷(−5)
It can be written as :
[tex]\dfrac{30xy^3}{(-5xy)}=\dfrac{30}{-5}\times \dfrac{xy^3}{xy}\\\\=-6\times y^2\\\\=-6y^2[/tex]
So, the value of the given expression is [tex]-6y^2[/tex].
the TV Margaret wants cost $270 This week only, the TV is discounted by 25%. Margaret must pay 6% sales price. which saves the most money?
A. Taking the discount first then adding on the sales tax
B. Adding on the sales tax first and then taking the 25% discount
C. Both methods save the same amount of money
Answer:
C
Step-by-step explanation:
Method A:
270 decrease 25% =
270 × (1 - 25%) = 270 × (1 - 0.25) = 202.5
202.5 increase 6% =
202.5 × (1 + 6%) = 202.5 × (1 + 0.06) = 214.65
Method B:
270 increase 6% =
270 × (1 + 6%) = 270 × (1 + 0.06) = 286.2
286.2 decrease 25% =
286.2 × (1 - 25%) = 286.2 × (1 - 0.25) = 214.65
