Answer:
8.6
Step-by-step explanation:
There is an easier way which is finding the slope of the equation but I'm going to stick to distance formula(which is easier for me).
For this, you would have to know the distance formula which is
d=√(x2−x1)^2+(y2−y1)^2
Which simplifies into [tex]\sqrt{(7)^2 +(5)^2}[/tex] which you get from 6-(-1) and -2-(-7)
Further simplifies into [tex]\sqrt{49+25}[/tex]
=[tex]\sqrt{74}[/tex]
=8.602325
use the distance formula:
√ ( x2 - x1 )² + ( y2 - y1 )²
√ ( 6 - ( - 1 ) )² + ( - 2 - ( - 7 ) )²
√ ( 7 )² + ( 5 )²
√ 49 +25
√ 74
8.602325267

*
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
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
. Neve is examining a tree limb. She notices that the smaller branches spiral away from the larger limb. The limb has 1 branch, then another single branch. After that, the branches spiral in the pattern {2, 3, 5, 8, …}. Can you model the tree growth with the Fibonacci sequence? Explain.
Answer:
[tex]a_1=2\\a_n=a_{n-1}+(n-1)\,,n>1[/tex]
Step-by-step explanation:
Given: The smaller branches spiral in the pattern [tex]\{2,3,5,8,...\}[/tex] from a larger limb.
To model: the tree growth with the Fibonacci sequence
Solution:
Take [tex]a_1=2[/tex]
Let [tex]a_n[/tex] denotes the [tex]n^{th}[/tex] term.
[tex]a_2=3=2+1=2+(2-1)=a_1+(2-1)\\a_3=5=3+2=3+(3-1)=a_2+(3-1)\\a_4=8=5+3=5+(4-1)=a_3+(4-1)[/tex]
So,
[tex]a_1=2\\a_n=a_{n-1}+(n-1)\,,n>1[/tex]
Answer:
Yes.
Step-by-step explanation:
The pattern in which the branches are growing off the limb is {1, 1, 2, 3, 5, 8, …}, meaning you can use the model with tree growth.

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)

what's equivalent to y-1=-5(x-4). A,y=-5x-19. B,y=-5x+19 C,y=-5x-21 D,y=-5+21
Answer:
it must be y=-5x+21
Step-by-step explanation:
lets type the equation in front of us and make it simple so we can deal with it
y-1=-5(x-4)
first thing you need to do is to remove those brackets by multiplying whats in the bracket by -5 like this
y-1=-5x+20 -5*x=-5,, -5*-4=20 (note: when you multiply negative with
negative result is positive)
then add each side by 1 so it will be
y=-5x+21

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
Can of soup has a radius of 3.4 centimeters. Can is 10.2 centimeters tall, what is the approximate area of the label that wrap around the can?
Answer:
218 cm²
Step-by-step explanation:
Can of soup has a radius of 3.4 centimeters. Can is 10.2 centimeters tall, what is the approximate area of the label that wraps around the can?
The formula to solve the above question is given as:
The curved or the lateral surface area of the cylinder = 2πrh
Where:
r = 3.4 cm
h = 10.2 cm
The curved or the lateral surface area of the cylinder = 2 × π × 3.4 cm × 10.2 cm
= 217.9 cm²
Therefore, the approximate area of the label that wraps around the can is
218 cm².

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.
