Given the series 2+ 6 + 18+
*
use an appropriate formula to find S12.
Please put full solution.
Answer: Samsung Galaxy S12
Answer:
S₁₂ = 531440
Step-by-step explanation:
There is a common ratio between consecutive terms, that is
r = 6 ÷ 2 = 18 ÷ 6 = 3
This indicates the sequence is geometric with sum to n terms
[tex]S_{n}[/tex] = [tex]\frac{a(r^n-1)}{r-1}[/tex] ( r ≠ 1 )
where a is the first term and r the common ratio
Here a = 2 and r = 3 , then
S₁₂ = [tex]\frac{2(3^{12}-1) }{3-1}[/tex]
= [tex]\frac{2(531441-1)}{2}[/tex]
= 531441 - 1
= 531440
Find the length indicated please!!
What is the 18th term in this sequence?

Central Fencing has been hired to fence the perimeter of a rectangular field. The length of the field is 42 - W feet, where W is the width of the field, and the area of the field must be more than 432 square feet. Find the bounds on the width of the field.
Answer:
10.3 is the width
Step-by-step explanation:
set up an equation
42w=432
divided both sides by 42
W=10.2857142857
to rounded it to nearest tenth it will be 10.3
to check your answer multiply 10.3 by 42 it will be 432
check check
Answer:
18 ≤ w ≤ 24
Step-by-step explanation:
A = l * w
A ≥ 432 sq ft.
l = 42 - w
432 ≤ (42 - w) (w)
432 ≤ -w² + 42w
w² - 42w ≥ 432
Substitute values for w
w = 18
w = 24

Define the following vocabulary words
A.Factor
B.Variable
C.Product
D.Coefficient
Answer:
c
Step-by-step explanation:
Answer:
A factor is a circumstance or action that will/would influence an outcome.
A variable is something that is liable to change or something that isn't temporary.
A product is a result of an action or a process.
Coefficient means a quantity is being multiplied by the variable, for instance:
4 (the coefficient) X (the variable) - (the operator) 7 (the constant) = 5 (the constant)
What that looks like is: 4x-7=5.

A cylinder has a base with a radius of 7 cm and a volume of 615.44 cm3. Use 3.14 for π . Write and solve an equation to find the height of the cylinder.
Answer:
The height is 4 cm
Step-by-step explanation:
V = (pie) x radius² x height
615.44 cm³ = (3.14) x 7² x h
h = 615.44 cm³/(3.14 x 49)
h = 615.44 cm³/153.86
h = 4 cm²

A sculpture is in the shape of a cylinder. The sculpture has a diameter of 10 feet and a height of 21 feet. Which measurement is closest to the total surface area of the sculpture in square feet?
Answer:did u get the answer?
Step-by-step explanation:sorry
The measurement of total surface area of the sculpture in square feet is 814 square feet.
What is the surface area of a cylinder?The surface area of a cylinder can be calculated by adding the area of its lateral surface to the sum of the areas of its two circular ends. The formula for lateral surface area is given by: 2πrh
where r is the radius of the circular base and h is the height of the cylinder.
Since the diameter of the cylinder is 10 feet, the radius is 10/2 = 5 feet.
So, the lateral surface area of the cylinder = 2 × π × 5 × 21 = 210π square feet.
The area of each circular end is given by πr². Since the radius is 5 feet, the area of each circular end is π × 5² = 25π square feet.
Therefore, the total surface area of the cylinder is 210π + 2 × 25π = 260π square feet.
The value of π is approximately 3.14, so the surface area of the cylinder is approximately 260 × 3.14 = 816.4 square feet.
So, the closest measurement of the total surface area of the sculpture in square feet is 816 square feet.

Dan bought a new computer for $900. Each year, the value of the computer decreased by 25% of the previous year's value. At this rate, what can Dan expect the approximate value of the computer to be after 8 years?
Answer:
$90
Step-by-step explanation:
Given data
Price= $900
Rate= 25%
Time= 8 years
Let us apply the compounding formula
A= P(1-r)^t >>>>note that the negative sign is because of the depreciation
substitute
A= 900(1-0.25)^8
A= 900(0.75)^8
A= 900*0.100
A= $90
Hence the value of the car after 8 years will be $90

A Speedboat increases in speed uniformly from 20m/s to 30m/s for 12.2 s. What is the acceleration of the speedboat?
Answer:
0.82 m/s^2
Step-by-step explanation:
Given data
initial velocity=20m/s
Final velocity= 30m/s
Time = 12.2s
Applying the formula
a= v-u/t
a= 30-20/12.2
a= 10/12.2
a= 0.819
a=0.82 m/s^2

Charlotte and Riley walked 6/10 of a mile to school one day, and then after school they walked 3/8 of a mile to the store. From the store back home was another 2/5 of a mile. How far did the girls walk in all?
Answer: The girls walked [tex]1\dfrac38[/tex] miles.
Step-by-step explanation:
Given: Distance from home to school = [tex]\dfrac{6}{10}[/tex] mile
Distance from school to store = [tex]\dfrac38[/tex] mile
Distance from store to home = [tex]\dfrac25[/tex] miles
Total distance = [tex]\dfrac6{10}+\dfrac38+\dfrac25[/tex]
= [tex]\dfrac{6\times4+3\times5+2\times8}{40}[/tex] [L.C.M.(10,8,5)=40]
= [tex]\dfrac{24+15+16}{40}[/tex]
= [tex]\dfrac{55}{40}[/tex]
= [tex]\dfrac{11}{8}=1\dfrac38[/tex] miles
Hence, The girls walked [tex]1\dfrac38[/tex] miles.
