Answer:
arrowhead : 15
bone : 721
clay bowl : 0
necklace : 462
woven basket : -1200
Step-by-step explanation:
Consider sea level to be zero elevation, then anything above sea level is related to a positive number equal he elevation at which it was found, and anything below sea level would be associated with a negative number (the opposite of the depth at which it was found,as shown below:
arrowhead : 15
bone : 721
clay bowl : 0
necklace : 462
woven basket : -1200
Answer:
Step-by-step explanation:
arrow head is 15 feet because it is above sea level making it positive
bone 721 feet is also positive because anything positive is above sea level
clay is zero because it is at sea level so it is not positive or negative

Determine the explicit form of the function that describes the sequence below.
16, 24, 36, 54, ...
A. f(n) = 8n + 8
B. f(n) = 16(3/2)^(n - 1)
C. f(n) = 3/2(n - 1) + 16
D. f(n) = 3/2(16)^(n - 1)
Answers
Answer:
B. f(n) = 16(3/2)^(n - 1).
Step-by-step explanation:
You can just substitute values. For questions like these, I usually use the second or third value to try the equations, because most of the time, the people who made these problems would make them all work for the first or last values.
A: 8n + 8 = 8 * 3 + 8 = 24 + 8 = 32. 32 is not equal to 36, so you can eliminate A.
B: 16 (3/2)^ (n - 1) = 16 * (1.5)^ (3 - 1) = 16 * (1.5)^ 2 = 16 * 2.25 = 36. 36 = 36, so you can keep this choice... for now.
C: 3/2 (n - 1) + 16 = 1.5 * (3 - 1) + 16 = 1.5 * 2 + 16 = 3 + 16 = 19. 19 does not equal 36, so you can eliminate C.
D: 3/2 (16)^ (n - 1) = 1.5 * (16)^ (3 - 1) = 1.5 * 16^2 = 1.5 * 256 = 384. 384 does not equal 36, so you can eliminate D as well.
Since A, C, and D do not work, you can say that the explicit form of the function would be Choice B.
Just to be sure, you can check using all four values...
f(1) = 16 * (1.5)^0 = 16 * 1 = 16 TRUE
f(2) = 16 * (1.5)^1 = 16 * 1.5 = 24 TRUE
f(3) = 16 * (1.5)^2 = 16 * 2.25 = 36 TRUE
f(4) = 16 * (1.5)^3 = 16 * 3.375 = 54 TRUE
Since all of the values match up, you can be sure that Choice B is the right answer.
Hope this helps! :)
The explicit form of the function that describes the sequence is
[tex]T_n[/tex] = 16 (1.5[tex])^{n-1[/tex].
What is Explicit form?Without expressing the other terms of the sequence, explicit formulas are always utilised to represent any term of the sequence. The word "explicit" means something that may be found directly without having to know the other phrases in the sequence. A single formula, known as the explicit formula, can be used to describe each term in a series in an individual way.
we have sequence
16, 24, 36, 54, ......
So, a = 16
r =24/16 = 1.5
So, the standard form of explicit form
[tex]T_n = a r^{n-1[/tex]
Then, [tex]T_n[/tex] = 16 (1.5[tex])^{n-1[/tex]

Next:
first pirate --> 1/2 + 3/4 = 5/4 coins
second pirate --> 3/2 - 3/4 = 3/4 coins
Next:
first pirate --> 5/4 - 5/8 = 5/8 coins
second pirate --> 3/4 + 5/8 = 11/8 coins

express 3m24cm in kilometers,leaving your answer in standard form
Answers
Answer:
0.00324 kilometres
Step-by-step explanation:
Remember:
100 centimeters = 1 meter
1000 meters = 1 kilometer
So first, let's add together the meters and centimeters. To do that, we have to convert the meters to centimeters. That would become 300 centimeters, then you add the 24 centimeters to get 324 centimeters. Then, you convert that to kilometers. You can use a calculator for this, but I'll show you how to do this without a calculator. Since 100 centimeters is one meter, and 1000 meters equals to one kilometer, there would be 5 spaces from 324 to our answer, so you move the invisible decimal point 5 spaces to the left, and you get your answer, which is 0.00324 kilometres!

"Filipe" was playing with a triangle on a coordinate plane. The triangle's area is 242424 square units. The largest circle he can fit in the triangle is centered at (0,0)(0,0)left parenthesis, 0, comma, 0, right parenthesis and passes through the point (1.2,1.6)(1.2,1.6)left parenthesis, 1, point, 2, comma, 1, point, 6, right parenthesis. Approximately what percentage of the triangle does the circle cover?
Answers
Answer:
52.33% is the correct answer.
Step-by-step explanation:
Given that:
Area of triangle = 24 sq units
Center of Circle is at (0, 0) and the circle passes through (1.2, 1.6).
To find: The percentage of triangle covered by circle.
Solution: To find the required percentage, we need to find the area of circle.
To find the area of circle, we need the radius of circle.
Radius of circle is the distance between the center of circle and any point that lies on the periphery of the circle.
We can use Distance formula :
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Radius = [tex]\sqrt{(1.2-0)^2+(1.6-0)^2} = \sqrt{1.44+2.56} = \sqrt{4} = 2\ units[/tex]
Now, area of circle is given by the formula:
Area = [tex]\pi r^{2}[/tex]
Area = 3.14 [tex]\times 2^{2}[/tex] = 12.56 sq units
Percentage of Triangle covered:
[tex]\dfrac{Area\ of\ circle}{Area\ of\ triangle}\times 100\\\Rightarrow \dfrac{12.56}{24}\times 100\\\Rightarrow 52.33\%[/tex]
Hence, 52.33% is the correct answer.

10 tolas gold bought from American market at $ 553 per tola is sold in Nepal at 20% customs duty charge and 13% VAT. At what price should it be sold ?
Answers
Answer: $735.49
Step-by-step explanation:
Given, the price of 10 tolas gold bought from American market = $553
Custom duty charge = 20%
VAT = 13%
Custom duty charge = 20% of $553
= 0.20 x 553 [we divide a perecntage to convet it into decimal]
= $110.6
VAT = 13% of $553
= 0.13 x 553
= $71.89
Selling price = Original price +Custom duty charge + VAT
= $553+$110.6+ $71.89
= $735.49
Hence, it should be sold at $735.49 .

Step-by-step explanation:
The given limit problem is
[tex]\lim_{x\to 0}\dfrac{-7+x}{x^2}[/tex]
Left hand limit of the function is
[tex]LHL=\lim_{x\to 0^-}\dfrac{-7+x}{x^2}=\lim_{h\to 0}\dfrac{-7+(0-h)}{(0-h)^2}[/tex]
[tex]LHL=\lim_{h\to 0}\dfrac{-7-h}{h^2}[/tex]
Applying limit, we get
[tex]LHL=-\infty[/tex]
Right hand limit of the function is
[tex]RHL=\lim_{x\to 0^+}\dfrac{-7+x}{x^2}=\lim_{h\to 0}\dfrac{-7+(0+h)}{(0+h)^2}[/tex]
[tex]RHL=\lim_{h\to 0}\dfrac{-7+h}{h^2}[/tex]
Applying limit, we get
[tex]RHL=-\infty[/tex]
Since, LHL=RHL, therefore limit of the function exist at x=0.
Hence, [tex]\lim_{x\to 0}\dfrac{-7+x}{x^2}=-\infty[/tex].

Step-by-step explanation:
Given
[tex]f(x) = x^3 - 9x[/tex]
[tex]Interval: (12,6)[/tex]
Required
Determine the average rate of change
Average rate is calculated as thus;
[tex]A(x) = \frac{f(b) - f(a)}{b - a}[/tex]
In this case; b = 12 and a = 6
Calculating f(12)
[tex]f(12) = 12^3 - 9 * 12[/tex]
[tex]f(12) = 1728 - 108[/tex]
[tex]f(12) = 1620[/tex]
Calculating f(6)
[tex]f(6) = 6^3 - 9 * 6[/tex]
[tex]f(6) = 216 - 54[/tex]
[tex]f(6) = 162[/tex]
Substitute 12 for b and 6 for a in [tex]A(x) = \frac{f(b) - f(a)}{b - a}[/tex]
[tex]A(x) = \frac{f(12) - f(6)}{12 - 6}[/tex]
Substitute values for f(6) and f(12)
[tex]A(x) = \frac{1620 - 162}{12 - 6}[/tex]
[tex]A(x) = \frac{1458}{ 6}[/tex]
[tex]A(x) = 243[/tex]

Explanation:
The rectangular prism (aka rectangular block) has dimensions 2, 4 and 3. You can say they are the length width and height. The volume is 2*4*3 = 24 cubic cm.
The trapezoid's volume is found by multiplying the area of the trapezoidal face by the depth of 3 cm. Let's find the area of the trapezoid first
A = area of trapezoid
A = height*(base1+base2)/2
A = 2*(4+2)/2
A = 6
Then we multiply this with the depth of 3 cm to get 6*3 = 18 cubic cm
Lastly, we subtract the two volumes
difference in volume = (rectangular block) - (trapezoidal block)
difference in volume = 24 - 18
difference in volume = 6 cubic cm
----------
An alternative is to find the volume of each triangular piece on the left and right sides. Then add up those portions to get the answer. In a way, you can think of those triangular wedges as empty space.

Answer:
A) U′ (0, 1), V′ (2, 2), W′ (2, 0)
Step-by-step explanation:
The coordinate plane showing Triangle UVW is found online and attached below.
From the graph, the coordinates of the vertices of the triangle are:
U(0,3), V(6,6) and W(6,0)
When you dilate a point (x,y) with a scale factor of 1/3, you obtain: [tex]\left(\dfrac{x}{3}, \dfrac{y}{3}\right)[/tex]
Therefore, applying the dilation [tex](x,y) \rightarrow \left(\dfrac{x}{3}, \dfrac{y}{3}\right)[/tex], we have:
[tex]U(0,3) \rightarrow U'(\frac{0}{3} ,\frac{3}{3})=U'(0 ,1)\\\\V(6,6) \rightarrow V'(\frac{6}{3} ,\frac{6}{3})=V'(2 ,2)\\\\W(6,0) \rightarrow W'(\frac{6}{3} ,\frac{0}{3})=W'(2 ,0)[/tex]
The coordinates of the resulting triangle U′V′W′ are:
U′ (0, 1), V′ (2, 2), W′ (2, 0)
The correct option is A.
