Find the slope of the line parallel to the line passing through the given points: (-2, 8) and (-6, 6)
Answer:
2
Step-by-step explanation:
Use the points to find the slope, using the formula (y2 - y1) / (x2 - x1).
[tex]= \frac{-6-(-2)}{6-8}[/tex] = -4/-2 = 2
Since it's just asking for the slope, the answer is 2 (any parallel lines have the same slope).
Can someone show me how to figure out the slope? I think its -3/1 but I'm not 100% sure.

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

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

To find:
The simplified form of the expression.
Solution:
We have,
[tex]\sqrt[3]{48}=\sqrt[3]{8\cdot \_\_}=[/tex]
The expression [tex]\sqrt[3]{48}[/tex] can be written as
[tex]\sqrt[3]{48}=\sqrt[3]{8\cdot 6}[/tex]
[tex]\sqrt[3]{48}=\sqrt[3]{8}\cdot \sqrt[3]{6}[/tex] [tex][\because \sqrt[3]{ab}=\sqrt[3]{a}\sqrt[3]{b}][/tex]
[tex]\sqrt[3]{48}=2\cdot \sqrt[3]{6}[/tex]
[tex]\sqrt[3]{48}=2\sqrt[3]{6}[/tex]
Therefore, [tex]\sqrt[3]{48}=\sqrt[3]{8\cdot 6}=2\sqrt[3]{6}[/tex].

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.

Find the shortest length of wood that can be cut into equal lengths of 3m. 8
and 12m
Answer:
24
Step-by-step explanation:
Find LCM of 3 8 and 12
(calculation attached)
lcm = 3 x 2 x 2 x 2 = 24
i hope im right!
The shortest length of the wood will be 24 meters.
The Least Common Multiple (LCM) refers to the common multiple that is the least (smallest) among all possible multiples for both numbers. Calculating this least common multiple for numbers is made easier by the LCM formula.
Given that the length of the wood is 3m, 8m, and 12 m. The shortest length will be calculated by taking the least common factor of the given lengths 3m, 8m, and 12 m.
The least common factor is calculated as:-
3 = 3 x 1
8 = 2 x 2 x 2
12 = 2 x 2 x 3
LCM = 3 x 2 x 2 x 2 = 24
Hence, the shortest length of the wood will be 24 meters.

What is the volume of the circular cylinder if height is 25 and circumference 12
Answer:
V = 900π ≈ 286.47 units³
Step-by-step explanation:
C = 2πr
12 = 2πr
r = 12/2π = 6/π
V = 2πr²h
V = π(6/π)²(25) = π(36/π²)(25)
V = 36/π(25) = 900/π ≈ 286.47

If f(x) = 2x – 6 and g(x) = x – 2x2, find each value.
f(h + 9)
Answer:
Solution for If f(x) = 2x – 6 and g(x) = x – 2x2, find each value. f(2)
The required value of each function is
f(h + 9) = 2(h + 6)
g(h + 9) = -(2h + 19)(h - 9)
What is a function?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y.
Now the given functions are,
f(x) = 2x – 6
g(x) = x – 2x²
Now putting x = h + 9 in f(x) and g(x)we get,
f(h + 9) = 2(h + 9) – 6
⇒ f(h + 9) = 2h + 18 – 6
⇒ f(h + 9) = 2h + 12
⇒ f(h + 9) = 2(h + 6)
and
g(h + 9) = (h + 9) – 2(h + 9)²
⇒ g(h + 9) = h + 9 – 2(h² + 81 + 18h)
⇒ g(h + 9) = h + 9 – 2h² + 162 + 36h
⇒ g(h + 9) = -2h² + 37h + 171
⇒ g(h + 9) = -(2h + 19)(h - 9)
Thus, the required value of each function is
f(h + 9) = 2(h + 6)
g(h + 9) = -(2h + 19)(h - 9)

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
