Madame Pickney has a rather extensive art collection and the overall value of her collection has been increasing each year. Three years ago, her collection was worth $600,000. Two years ago, the value of the collection was $690,000 and last year, the collection was valued at $793,500.
Assume that the rate at which Madame Pickney’s art collection’s value increase remains the same as it has been for the last three years. The value of the art collection can be represented by a geometric sequence. The value of the collection three years ago is considered the first term in the sequence.
What explicit rule can be used to determine the value of her art collection n years after that?
Answer:
B. 600,000 (1.15)^{n-1}
Step-by-step explanation:
The n-th term of a geometric sequence with initial value a and common ratio r can be determined by multiplying the first term of the sequence (i.e. initial value a) by r^{n-1}.
The first term (i.e. initial value a) is 600,000.
The common ratio r can be calculated by dividing any two consecutive terms in the sequence:
r = 690,000/600,000 = 1.15 or r = 793,500/690,000 = 1.15
Thus, we get the answer:
the explicit rule that can be used to determine the value of the art collection n years after that is 600,000 (1.15)^{n-1}
Answer:an=600,000(1.15)^n−1

The quiz says 140 is wrong, but I don’t know if that’s a problem on the teacher’s end or not, because everyone here says it’s 140
Answer:
I believe the answer is 110.
Answer:
110°Step-by-step explanation:
In this problem we need to use the Inscribed Angle theorem, which states that an inscribed angle is one-half its subtended arc.
[tex]\angle C=\frac{1}{2}arc(DB)=70\°[/tex]
Then, we use the theorem about a cyclic quadrilateral, which is an inscribed quadrilateral: "the opposite angles in a cyclic quadrilateral are supplementary".
[tex]\angle C + \angle A = 180\°\\\angle A = 180\° - \angle C\\\angle A = 180\° - 70\° \\\angle A = 110\°[/tex]
Therefore, the answer is 110°
The area of the base of a rectangular prism is 36 cm2. The height of the prism is 3 5 6 cm. What is the volume of the prism?
Answer:
138 cm³
Step-by-step explanation:
Given in the question that base of the rectangular prism = 36 cm²
Height of the prism = 3 5/6 cm = 23/6
We know that the volume of a rectangular prism with base area B and height H is given by
Volume = B(H)Plug values in the formula above to find the volume of the prism
Volume = 36(23/6)
= 6(23)
= 138 cm³
So the volume of prism = 138 cm³

A police department reports that the probabilities that 0, 1, 2, and 3 domestic disputes will be reported in a given day are 0.53, 0.43, 0.03, and 0.01, respectively. Find the mean.
Answer:
The mean of the outcomes is 0.52.
Step-by-step explanation:
Multiply each possible outcome {0, 1, 2, 3} by the respective probability, and then add up the four products:
0·0.53 + 1·0.43 + 2·0.03 + 3·0.01. This comes out to:
0 + 0.43 + 0.06 + 0.03 = 0.52
The mean of the outcomes is 0.52.
The mean of the outcomes will be equal to 0.52.
What is mean?Mean is defined as the ratio of the sum of the number of data sets to the total number of data.
Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Multiply each possible outcome {0, 1, 2, 3} by the respective probability, and then add up the four products:

Find the base of a triangle with the same area as the shaded region. The height of the triangle is 25 feet. Show ALL work.
(Hint
Area of a rectangle = Length× Width
Area of a triangle = 1/2× Base× Height)
Answer:
32 ft
Step-by-step explanation:
find the area of the large rectangle:
30 x 16 = 480
find the area of the small rectangle:
10 x 8 = 80
subract the small rectangle from the big rectangle to get the area of the shaded region:
480 - 80 = 400
now plug this area and the height into the equation for triangle area:
A = bh/2
400 = b(25)/2 multiply both sides by 2
2(400) = 2(25b/2)
800 = 25b divide both sides by 25
800/25 = 25b/25
32 = b
For this case we have that the area of the shaded region is given by the subtraction of the large rectangle minus the small rectangle.
[tex]A_ {sr} = 30 * 16-10 * 8\\A_ {sr} = 480-80\\A_ {sr} = 400[/tex]
Thus, the area of the shaded region is [tex]400 \ ft ^ 2[/tex]
If the triangle must have the same area and a height of 25, then we have:
[tex]400 = \frac {1} {2} b * 25\\400 = 12.5b[/tex]
Dividing between 12.5 on both sides of the equation:
[tex]b = 32[/tex]
Thus, the base of the triangle is 32.

How can the radian measure of an angle determine the arc length on the unit circle?
Step-by-step explanation:
Arc length is defined as:
s = rθ
where r is the radius and θ is the angle in radians
A unit circle has a radius of 1, so the arc length is equal to the radian measure of the angle.
The radian measure determines the arc length on the unit circle using the formula s = θ for a unit circle (radius = 1). Radians, being a ratio of arc length to radius, allow for direct conversion between angle and arc length, facilitating calculations and conversions between radians and degrees.
The radian measure of an angle can determine the arc length on the unit circle by using the formula arc length (s) = radius (r) × angle in radians (θ). Since the unit circle has a radius of 1, this simplifies to s = θ. The concept of radians is crucial here; a radian is defined as the ratio of the arc length to the radius of the circle, making it a dimensionless unit. This relationship remains constant regardless of the circle's size, meaning the radian measure directly gives the arc length on the unit circle.
For a full revolution of 2π radians (360 degrees), the arc length is equal to the circumference of the circle, which is 2πr. In the case of the unit circle, this equates to an arc length of 2π. This principle allows for the conversion between radians and degrees, and calculation of arc lengths for any given angle measured in radians.

Emma and Sydney go to the movie theater and purchase refreshments for their friends.
Emma spends a total of $25.50 on 7 drinks and 2 bags of popcorn.
Sydney spends a total of $52.50 on 5 drinks and 10 bags of popcorn.
Write a system of equations that can be used to find the price of one drink and the price of one bag of popcorn.
Using these equations, determine and state the price of a bag of popcorn, to the nearest cent.
25.50 = 7d + 2p
52.50 = 5d + 10p
These are the two equations we're going to use to determine the price of popcorn.
First we need to eliminate one set of variables. Let's eliminate the drinks.
127.50 = 35d + 10p
-367.50 = -35d + -70p
-240 = 0d - 60p
-240 = -60p
P = 4.00
So, popcorn is $4, right? Let's keep working on the problem so we can double check...
So, now let's add the $4 as the variable for P.
25.50 = 7d + 8
52.50 = 5d + 40
17.50 = 7d
12.5 = 5d
d = 2.5
d=2.5
This checks out! Since both equations state that drinks are 2.50, that means we have the right pricing for popcorn... $4.00
Popcorn is $4.00, drinks are $2.50

Step-by-step explanation:
Using Euler's relationship for polyhedra
F + V - E = 2
F is number of faces, V number of vertices, E number of edges
Rearrange to express E as the subject
Add E to both sides
F + V = E + 2 ( subtract 2 from both sides )
F + V - 2 = E ← substitute values
20 + 12 - 2 = E, hence
E = 30

If ΔFGH ≅ ΔIJK, which segment is congruent to segment GH?
segment HF
segment JK
segment IJ
segment FG
Answer:
Segment JK is congruent to segment to GH ⇒ 2nd answer
Step-by-step explanation:
* Lets revise the meaning of congruent triangles
- When two triangles are congruent then they will have exactly the
same three sides and exactly the same three angles
- Congruent triangles have same areas and same perimeters
- Ex: If Δ ABC ≅ Δ XYZ, then their corresponding sides are congruent
and their corresponding angles are equal
side AB ≅ side XY , side BC ≅ side YZ , side AC ≅ side XZ
angle A ≅ angle X , angle B ≅ angle Y , angle C ≅ angle Z
* Lets solve the problem
∵ Δ FGH ≅ Δ IJK
- The corresponding sides are:
# FG and IJ
# GH and JK
# FH and IK
∵ The corresponding side of GH is JK
∵ The corresponding sides are congruent
∴ GH ≅ JK
∴ Segment JK is congruent to segment to GH

Which answer is the approximate standard deviation of the data set?
Answer:
3.4
Step-by-step explanation:
Standard deviation of a population is defined as:
σ² = ∑(xᵢ − μ)² / n
The standard deviation of a sample is defined as:
s² = ∑(xᵢ − x)² / (n - 1)
It's not clear which one we have, so let's calculate both.
First, we must find the mean.
μ = (5+12+15+10+12+6+8+8) / 8
μ = 9.5
Now we find the squares of the differences:
(5-9.5)² + (12-9.5)² + (15-9.5)² + (10-9.5)² + (12-9.5)² + (6-9.5)² + (8-9.5)² + (8-9.5)²
= 80
Divide by n:
σ² = 80 / 8
σ² = 10
And take the square root:
σ = √10
σ ≈ 3.2
That's not one of the answers, so let's try the standard deviation of a sample instead of a population.
Instead of dividing by n, we'll divide by n-1:
s² = 80 / 7
And take the square root:
s = √(80/7)
s ≈ 3.4
So that must be it.
A student solved this problem and said the answer is 81 2 pounds. Jill's club bought 42 5 pounds of hot dogs, 31 2 pounds of hamburger, and 23 10 pounds of chicken for the picnic. How much meat did they buy altogether? Is the student's answer reasonable? No, the answer is not reasonable. It should be about 12 pounds. No, the answer is not reasonable. It should be about 15 pounds. No, the answer is not reasonable. It should be about 10 pounds. Yes, the answer is reasonable.
Answer:
D. No the answer is not reasonable. it should be about 10 pounds.
I took the test.
Answer:
No, the answer is not reasonable. It should be about 10 pounds.
Step-by-step explanation:
Given,
The quantity of hot dog bought by Jill's club = [tex]4\frac{2}{5}[/tex] pounds,
Hot dog = [tex]3\frac{1}{2}[/tex] pounds
Hamburger = [tex]2\frac{3}{10}[/tex] pounds
So, the total quantity of meat they bought
[tex]=4\frac{2}{5}+3\frac{1}{2}+2\frac{3}{10}[/tex]
[tex]=\frac{22}{5}+\frac{7}{2}+\frac{23}{10}[/tex]
[tex]=\frac{44+35+23}{10}[/tex] ( Adding fractions ),
[tex]=\frac{102}{10}[/tex]
[tex]=10.2\text{ pounds}[/tex]
Since, [tex]8\frac{1}{2}=\frac{17}{2}=8.5[/tex]
[tex]\implies 8.5\neq 10.2[/tex]
Hence, the student's answer is not reasonable it should be about 10 pounds.

Math PT Question 19 Which of the following is the correct equation for the trend line in the scatter plot ?
Using the points where the blue line crosses the X and Y axis:
(0,5) ans (-1, 0)
The slope is the change in Y over the change in X:
0-5 / -1 - 0 = -5/-1 = 5
Slope = 5
Y intercept = y1 = 5
Equation = y = 5x+5
Answer:
The correct equation for the trend line is y = 5x + 5
Step-by-step explanation:
* Lets revise the form of the equation of the line
- The slope intercept form is y = mx + b, where m is the slope of
the line and b is the y-intercept
- In the problem we have a trend line in the scatter-plot
- we cant find the exact value of the slope of the line from the points
in the scatter-plot because the line is best fit to the point, then we
will start with the y-intercept of the line
- From the graph the line intersect the y-axis at point (0 , 5)
∴ The y-intercept is 5
- We have two answers have y- intercept = 5, the first and second
answer, the right answer is one of them
- From the graph try to find two points closed the the line and use
them to find the slope of the line
- There are two points approximately closed to the line at points
(0 , 5) and (-1 , 0)
- Lets use the rule of the slope of a line which passes through points
(x1 , y1) and (x2 , y2)
- The slope of the line = (y2 - y1)/(x2 - x1)
∵ The point (0 , 5) is (x1 , y1) and point (-1 , 0) is (x2 , y2)
∵ x1 = 0 , x2 = -1 and y1 = 5 , y2 = 0
∴ the slope = (0 - 5)/-1 - 0 = -5/-1 = 5
∵ The equation of the line is y = mx + b
∵ m = 5 and b = 5
∴ The equation is y = 5x + 5

[tex]\frac{x^2-5}{x^2+5}=\frac{x^2-5}{(-5)^2+5}=\frac{x^2-5}{30}[/tex]
[tex]\frac{x-3}{x^2-25}=\frac{x-3}{(-5)^2-25}=\frac{x-3}{0}[/tex]
[tex]\frac{x^2-25}{2x^2+5}=\frac{x^2-25}{2(-5)^2+5}=\frac{x^2-25}{55}[/tex]
[tex]\frac{2x+1}{x^2+25}=\frac{2x+1}{(-5)^2+25}=\frac{2x+1}{50}[/tex]
[tex]\frac{(x-2)(x-5)}{(x+3)(x+5)}=\frac{(x-2)(x-5)}{(x+3)((-5)+5)}=\frac{(x-2)(x-5)}{0}[/tex]

Step-by-step explanation:
The first differences of the given terms are ...
8 -5 = 3
11 -8 = 3
These are the same value, so we see this sequence is an arithmetic sequence with a common difference of 3. The first term is 5.
The explicit formula for the n-th term is ...
an = a1 +d(n -1)
We know a1=5, d=3, and we want to find the value for n=22. Hence ...
a22 = 5 +3(22 -1) = 5 +63 = 68
The 22nd term is 68.
PLEASE HELP! I been stuck on this assignment for over 2 weeks. My teacher gave me a simple explanation when I asked for help, but I still didn't understand it.

Thomas wants to make a box with no lid out of a cardboard sheet to hold a marble collection. He plans to cut out four congruent squares from all corners of the sheet and then fold up the sides to make the box.
Thomas buys a cardboard sheet that is 8 by 12 inches. Let x be the side length of each cutout. Create an equation for the volume of the box, find the zeroes, and sketch the graph of the function.
What is the size of the cutout he needs to make so that he can fit the most marbles in the box?
If Thomas wants a volume of 12 cubic inches, what size does the cutout need to be? What would be the dimensions of this box?
This has to do with polynomials by factoring.
Please EXPLAIN IT so that I UNDERSTAND it. Don't just give me the answer. THANK YOU so much in advance. :)
Answer:
Question 1: x = 0,6,4
Step-by-step explanation:
#1. If we let x be the side of the cut-out square, the formula for the volume of the box is
[tex]\text{Volume} = (12 - 2x)(8 - 2x)(x).[/tex]
Expanding gives us
[tex]\text{Volume} = 4x^3 - 40x^2 + 96x. [/tex]
To find the zeros, we need to set the equation to 0, and the values of x that would result to zero would be:
[tex]x = 0, 6, 4[/tex]
As how it is told 'he' wanted to make a box with no lid for his marble connection, 'he' wants to cut out four "Identical" squares from all of the corners of the sheet (which I'm assuming is that there is four corners) and by doing so he then wants to fold all the sides...
So he buys one that is 8 by 12 inches, so you can draw a box that is (8, 12) put an 'x' at all four corners and 'cut' it the corners out.
Here's the formula that you can use... Which could be either one I guess..
-Cube = a 3
-- a is the side length
-Rectangular prism = a * b * c
-- a, b, c are the length, width, and height
The volume of a cube is side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches.
Once you found a function I think you should use the quadratic equation, which is- y=x2-20x+96
And you could use that equation to graph it out... But if they want it to be the volume of 12 cubic inches then er-... Yeah that's were i'm stumped at... My apologies..
A binomial experiment is conducted with 7
trials. Each trial has a probability of 0.75 for
success.
a) Which of these is a theoretical probability P(r)
for r trials
i. P(2) = 0.012 iv. P(5) = 0.015
ii. P(3) = 0.058 v. P(6) = 0.311
iii. P(4) = 0.005
b) What is the theoretical probability that at least
4 of the trials are successful, rounded to three
decimal places?
c) What is the theoretical probability that at most
2 of the trials are successful, rounded to three
decimal places?
Answer:
Step-by-step explanation:
To calculate the theoretical probability here, we need three inputs: 1) the number of trials (which here is 7); the probability of success (which here is 0.75); and an integer representing the particular outcome (which here would be r: {0, 1, 2, 3, 4, 5, 6, 7}.
(a) Most of today's calculators have probability distribution functions built in. I've used binompdf(n,p,r) here. i. P(2) = 0.012 is correct; it's the result of typing in binompdf(7,0.75,2). ii. P(3) = 0.058 is correct. iii. P(4) = 0.005 is false; this probability is 0.173. iv. P(5) = 0.015 is false. v. P(6) = 0.311 is correct.
(b) The probability that at least four trials are successful is equivalent to P(4) + P(5) + P(6) + P(7). Another way in which to calculate this would be to add up P(0) + P(1) + P(2) + P(3) and subtract the resulting sum from 1.00: That comes to: 1 - (0.000 + 0.001 + 0.012 + 0.058), or 1 - 0.071, or 0.929
