f has a range of (-4, infinity), and a graph that is symmetric about the line x = -1 , and has a y- intercept of -3
Answers
The graph of the parabola is given at the end of the answer.
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
Considering the range and the symmetry line, the vertex of the function is at (-1,-4) and:
h = -1, k = -4.
Hence:
y = a(x + 1)² - 4.
It has a y-intercept of -3, that is, when x = 0, y = -3, hence we use it to find a as follows.
-3 = a - 4
a = 1.
Hence the function is:
y = (x + 1)² - 4.
The graph of this function is given at the end of the answer.

In Maths, Geometric Progression (GP) is a type of sequence where each succeeding term is produced by multiplying each preceding term by a fixed number, which is called a common ratio. This progression is also known as a geometric sequence of numbers that follow a pattern. Also, learn arithmetic progression here. The common ratio multiplied here to each term to get a next term is a non-zero number. An example of a Geometric sequence is 2, 4, 8, 16, 32, 64, …, where the common ratio is 2.
A geometric progression or a geometric sequence is the sequence, in which each term is varied by another by a common ratio. The next term of the sequence is produced when we multiply a constant (which is non-zero) by the preceding term. It is represented by:
a, ar, ar2, ar3, ar4, and so on.
Where a is the first term and r is the common ratio.
Note: It is to be noted that when we divide any succeeding term from its preceding term, then we get the value equal to the common ratio.
Suppose we divide the 3rd term by the 2nd term we get:
ar2/ar = r
In the same way:
ar3/ar2 = r
ar4/ar3 = r
General Form of Geometric Progression
The general form of Geometric Progression is:
a, ar, ar2, ar3, ar4,…, arn-1
Where,
a = First term
r = common ratio
ar^(n-1) = nth term
On the first day, the video was viewed = 320 times.
the number of views was 25% more than the day before which means increasing 1.25 per day.
G.P.
Where common ratio r = 1.25
First term = f(1) = 320
The formula of nth term in G.P. =
[tex]F(n)= f(1) r^{n-1}[/tex]
So, nth term of the given situation :
[tex]F(n)= (320) 1.25^{n-1}[/tex]
Where f(n) denotes the number of views on an nth day.
[tex]F(n)= (320) 1.25^{n-1}[/tex]
So, the number of views Vera's video got on an nth day =
[tex]F(n)= (320) 1.25^{n-1}[/tex]

Point F is on line segment EG. Given EG = 12 and FG = 8, determine the length

Answers
Given that Point F is on line segment EG, the Length of segment EF is 4.
What is the numerical length of segment EF?A line segment is simply part of the line that connects 2 points.
Given the data in the question;
Point F is on line segment EGSegment EG = 12Segment FG = 8Length of segment EFSince Point F is on line segment EG, length of segment EG equals the sum of length of segment EF and length of segment FG.
Length of segment EG = Length of segment EF + Length of segment FG
Hence;
12 = Length of segment EF + 8
Subtract 8 from both sides and simplify
12 - 8 = Length of segment EF + 8 - 8
12 - 8 = Length of segment EF
4 = Length of segment EF
Length of segment EF = 4
Given that Point F is on line segment EG, the Length of segment EF is 4.

TermsIn a simplified polynomial expressed as a sum of products, each of the products is a "term." This expression has two terms:
-3a30bThe sign separating terms in the sum is generally considered to be part of the following term. If this were written 30b -3a, one of the terms would still be -3a.

Step-by-step explanation:
They can't have the same surface area, because the surface area is a 2-dimensional measure of a 3-dimensional object(for the most part), while the volume is 3-dimensional, so they would not share the same surface area due to them being mostly different structures despite having the same amount of cubic units.

Megan cuts pieces of colored felt to
create a logo of a sun behind a
mountain peak. Determine the
approximate total amount of felt used
in the logo.
Answers
The approximate total amount of felt used in the logo is 334.34 square cm
How to determine the approximate total amount of felt used in the logo?We have the following parameters on the logo:
Shapes = Semicircle and Triangle
Where
Semicircle:
Diameter = 18 cm
Triangle
Base = 16 cm
Height = 10 cm
The approximate total amount of felt used in the logo is calculated as
Amount = Area of semi-circle + Area of triangle
This gives
Amount = π(d/2)^2 + 0.5bh
So, we have
Amount = 3.14 * (18/2)^2 + 0.5 * 16 * 10
Evaluate
Amount = 334.34
Hence, the approximate total amount of felt used in the logo is 334.34 square cm

For $300≤x<$1,000, the discount is of 4%, hence the discounted price is 96% of the original price, that is:
D(x) = 0.96x, 300≤x<1,000
For $1,000≤x<$3,000, the discount is of 5%, hence the discounted price is 95% of the original price, that is:
D(x) = 0.95x, 1,000≤x<3,000.
For $3,000≤x<$5,000, the discount is of 6%, hence the discounted price is 94% of the original price, that is:
D(x) = 0.94x, 3,000≤x<5,000.
For $5,000≤x, the discount is of 10%, hence the discounted price is 90% of the original price, that is:
