Not geometricGeometric==================================================
Explanation for problem 1
Divide each term over its previous term.
term2/term1 = 48/60 = 0.8term3/term2 = 36/48 = 0.75We can stop here. The two results 0.8 and 0.75 do not match up, so we don't have a common ratio. Therefore, this sequence is not geometric. A geometric sequence must have each ratio of adjacent terms to be the same value throughout the list of numbers.
Side note: This sequence is arithmetic because we are subtracting the same amount each time (12) to generate each new term.
--------------------------------------
Explanation for problem 2
Like before, we'll divide each term by its previous term.
term2/term1 = 6/3 = 2term3/term2 = 12/6 = 2term4/term3 = 24/12 = 2term5/term4 = 48/24 = 2Each ratio found was 2. This is the common ratio and it shows we have a geometric sequence. It indicates that each term is twice that of its previous term. Eg: the jump from 12 to 24 is "times 2".

How to find the numeric value of a function or of an expression?To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.
Hence, for item 1, we have that:
p(a) = 4a² - 3.
(as the input variable is x, which appears only once in the expression).
For item 2, we have that:
r(2a) = 1 + 3(2a) = 1 + 6a.
For item 3, the expression is calculated in two parts, as follows:
r(a) = 1 + 3a.3r(a) = 3(1 + 3a) = 3 + 9a.For item 4, the expression is also calculated in two parts, as follows:
p(a) = 4a² - 3.-4p(a) = -4(4a² - 3) = -16a² + 12.For item 5, we have that:
p(a²) = 4(a²)² - 3 = 4a^4 - 3.
For item 6, we have that:
r(x + 2) = 1 + 3(x + 2) = 1 + 3x + 6 = 3x + 7.

MAD AND DAD are playing a game where a player flips a coin. If the coin lands on heads, the player receives 1 point. If the coin lands on tails, the player receives 2 points. The expected value of a turn is 1.5 points. Which of the following statement is true?
If they play a large number of turns, they should expect to average about 1.5 points per turn.
It is possible for a player to get 1.5 point on a turn.
The total number of points from two turns must be exactly 3 points.
Answer:
The answer is the first one "If they play a large number of turns, they should expect to average about 1.5 points per turn."
Step-by-step explanation:
This is essentially, because the 1st answer makes sense, while the other two are kind of ridiculous. Saying that the amount of points are exactly 3 points is not true, and saying it is possible to get 1.5 points on a turn is also impossible.

Given points A (0,0), B (4,0), C (0,2), D (0,0), E (2,0), and F (0,1), which of the following proves that
A ABC - A DEF?
Similar triangles may or may not have equal side lengths
Triangles ABC and DEF are similar by SSS theorem
How to determine the similarity statementThe coordinates of the two triangles are:
A (0,0), B (4,0), C (0,2), D (0,0), E (2,0), and F (0,1)
Calculate the lengths of both triangles using the following distance formula
[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]
For triangle ABC, we have:
[tex]AB = \sqrt{(0 -4)^2 + (0 -0)^2} = 4[/tex]
[tex]BC = \sqrt{(4 -0)^2 + (0 -2)^2} = 2\sqrt 5[/tex]
[tex]CA = \sqrt{(0 -0)^2 + (0 -2)^2} = 2[/tex]
For triangle DEF, we have:
[tex]DE = \sqrt{(0 -2)^2 + (0 -0)^2} = 2[/tex]
[tex]EF = \sqrt{(2 -0)^2 + (0 -1)^2} = \sqrt 5[/tex]
[tex]FD = \sqrt{(0 -0)^2 + (1 -0)^2} = 1[/tex]
Divide corresponding sides of the triangles to calculate the scale factor k
[tex]k = \frac{AB}{DE} = \frac{BC}{EF} = \frac{CA}{FD}[/tex]
This gives
[tex]k = \frac{4}{2} = \frac{2\sqrt 5}{\sqrt 5} = \frac{2}{1}[/tex]
Evaluate the quotients
[tex]k = 2 = 2 = 2[/tex]
Since the quotients are equal, then the triangles are similar
Hence, triangles ABC and DEF are similar by SSS theorem

1. We mentioned how the price of movie tickets has increased over time with inflation in Unit 6. Let’s let the equation y = 0.50(1.06)x represent the price of movie tickets for the years after 1950.
Using this equation, fill in the following T-table for the years 1950, 1960, 1970, 1980, and 1990. Use X = 0, 10, 20, 30, and 40 to represent these years (the number of years after 1950).
# years after 1950 X
Ticket Price $ Y
2. Answer these questions:
• Do these prices look reasonable?
• What is the y-intercept?
• Is this growth or decay?
3. Graph the points on the graph provided and draw a smooth curve to represent the graph of the equation.
4. Use the extended curve below to predict the ticket prices in the following years:
• 2000 (x = 50)
• 2010 (x = 60)
• Are these prices reasonable?
5. Answer these questions:
• What is the average price of a movie ticket where you live?
• What is the price of a matinee?
• Substitute the number of years after 1950 that it is right now into the equation y = 0.50(1.06)x. (For instance, if it is 2006, use x = 56.) What answer did you get?
• Why do you think this is the same or different from the first answer you gave in this question?
An exponential function is a function that has the form y = ab^x, where a represents the initial value, and b represents the rate
(1) How to fill the tableThe exponential function is given as:
[tex]y = 0.50(1.06)^x[/tex]
When x = 0, we have:
[tex]y = 0.50 * (1.06)^0 = 0.50[/tex]
When x = 10, we have:
[tex]y = 0.50 * (1.06)^{10} = 0.90[/tex]
When x = 20, 30 and 40 we have:
[tex]y = 0.50 * (1.06)^{20} = 1.60[/tex]
[tex]y = 0.50 * (1.06)^{30} = 2.87[/tex]
[tex]y = 0.50 * (1.06)^{40} = 5.14[/tex]
So, the complete table is:
Years after 1950 X : 0 | 10 | 20 | 30 | 40
Ticket Price $ Y : 0.50 | 0.90 | 1.60 | 2.87 | 5.14
(2) The y-intercept and the rateThe prices look reasonable.
The y-intercept is when x = 0.
So, the value of the y-intercept is 0.50
Also, the rate represents a growth.
This is so, because the rate is greater than 1
(3) The graphSee attachment for the graph of the exponential function
(4) The prices in 2000 and 2010When x = 50 and 60, we have:
[tex]y = 0.50 * (1.06)^{50} = 9.21[/tex]
[tex]y = 0.50 * (1.06)^60} = 16.49[/tex]
Hence, the prices in 2000 and 2010 are $9.21 and $16.49

Cylinders A and B have the same radius but different heights. Which statement correctly compares cylinder A and cylinder B?
Answer:
The volume of cylinder B is 3 times the volume of Cylinder A
because the cylinder volume = pi r² h
h = hight
pi is a constant N
The volume of cylinder B is 3 times the Volume of cylinder A.
Option A is the correct answer.
What is a cylinder?
A cylinder is a three-dimensional figure that has a radius and a height.
The volume of a cylinder is πr²h.
Example:
The volume of a cup with a height of 5 cm and a radius of 2 cm is
Volume = 3.14 x 2 x 2 x 5 = 62.8 cubic cm
We have,
Cylinder A:
Radius = 6 cm
Height = 10 cm
Volume.
= π x 6² x 10
= 360π _____(1)
Cylinder B:
Radius = 6 cm
Height = 30 cm
Volume.
= π x 6² x 30
= 3 x 360π ______(2)
From (1) and (2) we get,
The volume of cylinder B = 3 x the Volume of cylinder A.
Thus,
The volume of cylinder B is 3 times the Volume of cylinder A.

A rectangular prism has a volume of 60 cubic centimeters. If you triple the length of this rectangular prism, what will its new volume be? A rectangular prism has a volume of 60 cubic centimeters. If you triple the length of this rectangular prism, what will its new volume be?
216,000 cm3
63 cm3
20 cm3
180 cm3
Step-by-step explanation:
the volume of such an object is created by multiplying the 3 side length dimensions :
length × width × height.
if you triple one of them, then you bring that factor 3 one time into the volume multiplication, and the volume also triples .
in our case that is 60×3 = 180.
FYI
if you would triple fire example all 3 dimension lengths, you would bring that factor 3 into the volume multiplication 3 times (once for every dimension).
and so the volume would increase by the factor
3×3×3 = 27.
