Determine the Next three terms in the following sequence -1 1/2 -1/4 1/8
Answer:
-1/16 1/32 -1/64
Step-by-step explanation:
They are dividing by -2 each time; therefore, they multiply (1/4) x (-1/2), (-1/16) x (-1/2), (1/32) x (-1/2) because of the keep change flip rule.
Answer:
-
[tex] - \frac{1}{16} \\ \frac{1}{32} \\ \frac{ - 1}{64} [/tex]
Step-by-step explanation:
It's a geometric sequence with the common ratio r = -1/2
1st: -1
2nd: (-1)x(-1/2) = 1/2
3rd: (1/2) x (-1/2) = -1/4
4th: (-1/4) x (-1/2) = 1/8
so:
5th: (1/8) x (-1/2) = -1/16
6th: (-1/16) x (-1/2) = 1/32
7th: (1/32) x (-1/2) = -1/64

1. National Geographic is reporting on the migration patterns of Canadian Geese. One of
the birds they are tracking traveled from Ottawa, Canada to Jackson, Mississippi
Part A: What units would be best to describe this situation
Part B: While writing the article for the next edition of National Geographic, the reporter
estimates that this goose flew 2,552,000 yards. How many significant digits does
the reporter's estimate have?
Part C: The Editor in Chief decided that the reporter chose the incorrect units. The editor
wants the reporter to convert the distance to miles. Complete this conversion.
Part D: Your younger brother determined that the distance from Jackson to Tucson
Arizona is 7,159,680 feet. He claims that this is further than the distance to
Ottawa. Is he correctJustify your answer using mathematical evidence.
Answer:
Part A: The unit that would be best to describes the situations is to the mile
Part B: 4 significant figures
Part C: 1,450 miles
Part D: He is not correct
Step-by-step explanation:
Part A: By unit conversion, we have;
1 mile = 1,760 yards
Given that the distance from Ottawa, Canada to Jackson Mississippi is 2,552,000 yards it would best simplified into miles
Part B: The number of significant digits in the reporters estimate are the non-zero digits before the zeros in the number figure which are 2, 5, 5, and 2 or 4 significant figures
Part C: 2,552,000 yards = 2,552,000 yards/(1,760 yards/mile) = 1,450 miles
Part D: Given that the distance from Jackson to Tucson = 7,159,680 feet, we have;
1 mile = 5,280 feet
Therefore;
7,159,680 feet = 7,159,680 feet/(5,280 feet/mile) = 1,356 miles
Therefore, the claim that the distance from Jackson to Tucson which is 1,356 miles is further than the distance from Ottawa, Canada to Jackson Mississippi which is 1,450 miles is not correct because;
The distance from Jackson to Tucson 1,356 miles [tex]\ngtr[/tex] 1,450 miles which is the distance from Jackson to Ottawa
A student rides his bike to school with an average velocity of 10 miles per hour. It takes him 12 minutes to get to school. Write a function that models the student's distance from home. Use t for time in hours and d for distance. Then identify the domain and range of this situation using interval notation--label each one!
Answer:
The function is [tex]d=10t[/tex]
domain is 0 to 0.2 hour.
range is 0 to 2 miles.
Step-by-step explanation:
Given that,
Average velocity = 10 miles/hour
Time = 12 min = 0.2 hour
We need to write a function that models the student's distance from home
Using formula of distance
[tex]d=v\times t[/tex]
Where, v = velocity
t = time
d = distance
Put the value into the formula
[tex]d=10t[/tex]
This is a function.
We know that,
Domain :
Domain shows the time.
So, domain = 0 to 0.2 hour
Range :
Range shows the distance.
The range at t =0,
Put the value of t in the function
[tex]d = 10\times0=0[/tex]
The range at t =0.2 hour
[tex]d = 10\times0=0[/tex]
[tex]d=2\ miles[/tex]
So. range = 0 to 2 miles
Hence, The function is [tex]d=10t[/tex]
domain is 0 to 0.2 hour
range is 0 to 2 miles

Answer:
f(x) = -3x⁴ - 3x³ - 8x + 2
As x -> ∞, f(x) -> -∞
As x -> -∞, f(x) -> -∞
f(x) = 3x³ - 8x² - x + 1
As x -> ∞, f(x) -> ∞
As x -> -∞, f(x) -> -∞

Answer: E. (13, 31)
Step-by-step explanation:
Let x= first number
Let y= Second number
----------------------------------
y-5=2x
x+y=44
--------------------------------
y=2x+5
x+y=44
----------------------------
x+(2x+5)=44 ⇔ substitute y value in terms of x
x+2x+5=44
3x+5=44
3x=39
x=13

the measure of one angle of a triangle is three times the measure of a second angle. the measure of the third angle is 12 less than the sum of the other two. what are the measures of the 3 angles
PLEASEEEE HELP<333
Answer:
24, 72, and 84
Step-by-step explanation:
Let the first, second, and third angles be A, B, and C, respectively.
So, first of all, since the figure is a triangle, the three angles must total 180. Thus:
[tex]A+B+C=180[/tex]
Now, we are told that the measure of one angle (let's use A) is 3 times the measure of a second angle (B). So:
[tex]A=3B[/tex]
And the measure of the third angle (C) is 12 less than the sum of the other two (A&B). Therefore:
[tex]C=(A+B)-12[/tex]
For this equation substitute A for 3B:
[tex]C=(3B+B)-12[/tex]
Combine like terms:
[tex]C=4B-12[/tex]
So we have the following equations thus far:
[tex]A+B+C=180[/tex]
[tex]A=3B[/tex]
[tex]C=4B-12[/tex]
So, substitute A and C in for the first equation:
[tex]A+B+C=180\\(3B)+B+(4B-12)=180[/tex]
Combine like terms:
[tex]8B-12=180[/tex]
Add 12 to both sides:
[tex]8B=192[/tex]
Divide by 8:
[tex]B=24[/tex]
So, the second angle B is 24 degrees.
The first angle A is three times B. Thus, A is 3(24)=72 degrees.
And C is 12 less than the sum of them. Thus:
[tex]C=(72+24)-12\\C=96-12\\C=84[/tex]
So, our angles are:
24, 72, and 84
And we are done :)

Is "What is the area of the floor in this classroom?" a statistical question?
The answer is No
Explanation:
All statistical questions involve collecting numerical data (usually from a group of people) and then analyzing it to draw conclusions about the opinions of people of a certain phenomenon as the data varies depending on the response of each person. This process is not required to determine the area of the floor because this has a unique answer and can simply be found by measuring the height and width of the classroom and then multiplying both numbers. Also, this does not imply gathering a lot of data and the data does not vary.
The distance that a jogger travels at a constant speed of 6.5 miles per hour can be modeled by the linear function f(x)=6.5x, where x is the time in hours the jogger runs. What is the domain of this function? How would a graph of this function show it?
The domain of the function f(x) = 6.5x will be a positive real number.

The distance that a jogger travels at a constant speed of 6.5 miles per hour can be modeled by the linear function f(x) = 6.5x, where x is the time in hours the jogger runs.
We know that time is a scalar quantity. Then the value of the time is always greater than equal to zero.

if a right cylinder have the same radius and height as the oblique cylinder shown here, what is the volume of the right cylinder? Use 3.14 for pi. Round to the nearest whole number.
Answer:
[tex]\displaystyle V_\text{right} \approx 1696\text{ units}^3[/tex]
Step-by-step explanation:
Recall that the volume for an oblique cylinder is the same for the volume of a right cylinder. That is:
[tex]\displaystyle V_\text{right} = V_\text{oblique} = \pi r^2h[/tex]
Hence, find the volume of the oblique cylinder:
[tex]\displaystyle \begin{aligned} V_\text{oblique} & = (3.14)(6)^2(15) \\ \\ & = 1695.6 \text{ units}^3 \\ \\ &\approx 1696\text{ units}^3\end{aligned}[/tex]
Therefore:
[tex]\displaystyle V_\text{right} \approx 1696\text{ units}^3[/tex]
In conclusion, the volume of the right cylinder is about 1696 units³.
