What is a geometric sequence?In a geometric sequence, the ratio of two consecutive terms are always equal.
The general expression for the nth term is given as aₙ = a₁ × rⁿ⁻¹ .
The sum of n terms for this sequence is given as Sₙ = (rⁿ - 1)/(r - 1)
The given sequence is 1, 3, 7, 15, 31, 63...
Then, the sequence formed by subtracting the consecutive terms are given as,
3 - 1, 7 - 3, 15 - 7, 31 - 15, 63 - 31 .....
Which can be rewritten as,
2, 4, 8, 16, 32......
It is a geometric sequence as ratio of the consecutive terms are equal,
4/2 = 8/4 = 16/8
Hence, the required sequence is a geometric sequence found as 2, 4, 8, 16, 32......

Let the graph of g be a vertical stretch by a factor of 2, followed by a translation 5 units down of the graph of f(x) = e". Write a rule for g
Answer:
g(x) = 2e - 5
Step-by-step explanation:
f(x) = e
2 f(x) = 2e : vertical stretch by a factor 2
2 f(x) - 5 : transition 5 units down
g(x) = 2 f(x) - 5 = 2e - 5

x+8y=20
4x-y=14
Answer:
x=4
y=2
Step-by-step explanation:
x+8y=20
4x−y=14
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.
x+8y=20,4x−y=14
Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.
x+8y=20
Subtract 8y from both sides of the equation.
x=−8y+20
Substitute −8y+20 for x in the other equation, 4x−y=14.
4(−8y+20)−y=14
Multiply 4 times −8y+20.
−32y+80−y=14
Add −32y to −y.
−33y+80=14
Subtract 80 from both sides of the equation.
−33y=−66
Divide both sides by −33.
y=2
Substitute 2 for y in x=−8y+20. Because the resulting equation contains only one variable, you can solve for x directly.
x=−8×2+20
Multiply −8 times 2.
x=−16+20
Add 20 to −16.
x=4
The system is now solved.
x=4,y=2

Answer:
x = 4
Step-by-step explanation:
Combine like terms.
3x- 2x = 1x
New Equation: 1x + 1 = 5
Subtract 1 from 5.

What is the value of p?
A. 3.6
B 3.8
C.10.4
D.57.6
Answer:
A. p = 3.6
Step-by-step explanation:
4p = 14.4
To get p by itself we would divide by 4 on each side so
(4p / 4) = (14.4 / 4)
p = (14.4 / 4)
p = 3.6

A swimming pool is treated periodically to control harmful bacteria growth.
The concentration of bacterial per cm³ after t days is given by
C(t)
[tex] = 30t^2 -240t + 500 [/tex]
in how many days after a treatment will be concentration be minimal ?
Answer:
The answer is 4
Step-by-step explanation:
[tex]c \: (t) = {30ft}^{2} = - 240t + 500[/tex]
For a quadratic function as given to find the minimum you need to write it in vertex or find the vertex (the vertex in a quadratic function is thr maximum or minimum).
Use the next formula to find the t coordinate of the vertex (the time in the minimum concentration of bateria):
[tex]c \: (t) = {at}^{2} + bt + c \\ \\ tm = - \frac{b}{2a} [/tex]
For the given function:
[tex]tm = - \frac{ - 240}{(2)30} = \frac{240}{60} = 4[/tex]
The minimum concentration of bacteria will be after 4 days.

Write the equation, in standard form of the quadratic relation
Zeros of 5 and 6 and a y-intercept of 30
Answer:
[tex]f(x)=x^2-11x+30[/tex]
Step-by-step explanation:
The factored form of a quadratic is given by:
[tex]f(x)=a(x-p)(x-q)[/tex]
Where p and q are the zeros, and a is the leading coefficient.
The quadratic relation has zeros of 5 and 6, and it has a y-intercept of 30.
Since the zeros are 5 and 6, p and q are 5 and 6. Thus:
[tex]f(x)=a(x-5)(x-6)[/tex]
The y-intercept is 30. In other words, when x = 0, f(x) = 30:
[tex]30=a(0-5)(0-6)[/tex]
Solve for a:
[tex]30=a(-5)(-6)\Rightarrow 30=30a\Rightarrow a=1[/tex]
Therefore, our quadratic in factored form is:
[tex]f(x)=(x-5)(x-6)[/tex]
To find the standard form, expand:
[tex]\begin{aligned} f(x)&=(x-5)(x-6)\\&= (x-5)x+(x-5)(-6)\\&=(x^2-5x)+(-6x+30)\\&=x^2-11x+30\end{aligned}[/tex]

feet = 5/6 in a mile
Please give me a reasonable explanation, not just the answer. Thank you
One mile = 5,280 feet.
Understand?
I am assuming that you want to know what is 5/6 of a mile.
(5/6)(5,280) = 5(880) = 4,400 feet.
If by IN A MILE you mean division, then we do the following:
(5,280)/(5/6) = (5,280 • 6)/5 = 6,336.
Is either one or the other because your question is honestly not too clearly stated..

The value of the expression using sum will be (8y + xy + 4) / (2xy²).
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The expression is given below.
⇒ [(5y + 2) / (xy²)] + [(2x - 4) / (4xy)]
Simplify the expression, then we have
⇒ [(5y + 2) / (xy²)] + [(2x - 4) / (4xy)]
⇒ [4(5y + 2) / (4xy²)] + [y(2x - 4) / (4xy²)]
⇒ [(20y + 8) / (4xy²)] + [(2xy - 4y) / (4xy²)]
⇒ (20y + 8 + 2xy - 4y) / (4xy²)
⇒ (16y + 2xy + 8) / (4xy²)
⇒ (8y + xy + 4) / (2xy²)
The value of the expression using sum will be (8y + xy + 4) / (2xy²).
