Here it is mentioned that the there are two concentric circles this means that they have the same center.
The center of the circles are the origin [tex](0,0)[/tex].
Radius of the outer circle is
[tex]r=\dfrac{3800}{2}=1900\ \text{m}[/tex]
Equation of a circle
[tex](x-a)^2+(y-a)^2=r^2[/tex]
where
[tex]a\ \text{and}\ b\ \text{are the}\ x\ \text{and}\ y\ \text{coordinates of the center}[/tex]
[tex]r=\text{Radius of the circle}[/tex]
Here the equation will be
[tex](x-0)^2+(y-0)^2=1900^2\\\Rightarrow x^2+y^2=3610000[/tex]
The equation of the outer circle is [tex]x^2+y^2=3610000[/tex]

The orange shape is a dilation of the black shape. What is the scale factor of the dilation?1/10 1/2 10 2
Answer:
Scale = ¼
Step-by-step explanation:
See attachment for complete question.
In the attached, we have.
Width = 4 units. ----- Orange
Width = 16 units ------- Black

Is the relationship between the number of tickets sold and the number of hours proportional? If so, how many tickets were sold in 8 hours?
Answer:
640 tickets.
Step-by-step explanation:
8hours × 80 = 640
There are 640 tickets are sold in 8 hours.
What is Proportional?
The equality between two ratio is called Proportional.
Given that;
Number of hours for selling number of tickets.
Since, To check the relationship is proportional or not, we check the equality between two given ratio.
Hence, The ratio are;
Number of hours : Number of Tickets
= 3 : 240 : : 5 : 400
It can be solve as;
= 3/240 = 5/400
= 1/80 = 1/80
= 1:80 : : 1:80
Thus, The given relationship between the number of tickets sold and the number of hours is proportional.
Now, Let number of tickets in 8 hours = x
Then, By definition of proportional we get;
⇒ 3 : 240 :: 8 : x
Solve the proportional as;
⇒ 3/240 = 8/x
⇒ x = 8 × 80
⇒ x = 640
So, There are 640 tickets are sold in 8 hours.

Answer:
x = 5 + 5y/4
Step-by-step explanation:
I think its like this: 4x - 5y = 20
Add 5y to both sides: 4x = 20 + 5y
Divide both sides by 4: x = 20/4 + 5y/4

A probability experiment is conducted in which the sample space of the experiment is S={1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}. Let event E={2, 3, 4, 5, 6, 7}, event F={5, 6, 7, 8, 9}, event G={9, 10, 11, 12}, and event H={2, 3, 4}. Assume that each outcome is equally likely. List the outcome s in For G. Now find P( For G) by counting the numb er of outcomes in For G. Determine P (For G ) using the General Addition Rule.
Answer:
The answer is " [tex]\bold{\frac{2}{3}}[/tex]"
Step-by-step explanation:
Given set:
[tex]\to F \ or\ G = \{ 5,6,7,8,9,10,11,12\}[/tex]
In the above-given set, there are 8 elements and 12 possible outcomes so, the equation is:

[tex]=\frac{5}{12}+\frac{4}{12}- P(E \cap H)\\\\=\frac{6}{12}+\frac{3}{12}- \frac{1}{12}\\\\=\frac{6+3-1}{12}\\\\=\frac{8}{12}\\\\=\frac{2}{3}\\\\[/tex]
American Black Ducks migrate a great distance every year. A typical bird will travel 2,739 miles in 33 days. Which of the following best represents this trip with a constant unit rate of travel? 7.4A
Answer:
Rate of travel = 83 miles per day
Step-by-step explanation:
Given:
Total distance = 2,739
Number of days = 33 days
Find:
Rate of travel
Computation:
Rate of travel = Total distance / Number of days
Rate of travel = 2,739 / 33

When the output value of a real-valued function, f(x), is equal to f(-x), for all values of x inside the domain of f, the function is said to be an even function.
It is claimed that a real-valued function f(x) is an odd function when, for all values of x in the domain of f, the output value of f(-x) is equal to the negative of f(x).
Given:
As, we know the first graph graph of an odd function is at the same distance from the origin but in opposite directions and, graph of an even function remains the same after reflection about the y-axis.
So, The polynomial function for this graph is of odd degree and the leading coefficient is negative.
and, The polynomial function for this graph is of even degree and the leading coefficient is negative.

Sequence: 49, 36, 25, 16, 8, 4, 1 * Is this a arithmetic or geometric sequence? and if it is arithmetic find the common difference and if it is geometric find the common ratio? and please do not give me a stupid answer only smart people answer this if you know the answer to this you are smart.
Answer:
Step-by-step explanation:
The sequence is nor properly written. This is correct sequence
49, 36, 25, 16, 9, 4, 1...
Merely looking at the sequence, we can see that it doesn't form an arithmetic sequence nor does it form a geometric sequence.
The values of the sequence are all perfect squares.
Rewriting the sequence;
7², 6², 5², 4², 3², 2², 1²...
Now we can see that the base values for an arithmetic sequence as shown:
7, 6, 5, 4, 3, 2, 1...
We find the common difference of this sequence as shown
d = T2-T1 = T3-T2 = T4-T3
Given T1 = 7, T2 = 6, T3 = 5, T4 = 4
Substitute
d = 6-7 = 5-6 = 4-5 = -1
d = -1
Get the nth term using the sequence
Tn = a+(n-1)d
a is the first term
d is the common difference
n is number of terms
Tn = 7+(n-1)(-1)
Tn = 7+(-n+1)
Tn = 7+1-n
Tn = 8-n
Since their power are constant i.e squared, hence we will square the ntj term as well to get the nth term of the original sequence as;
Tn = (8-n)²
To conclude, we can say that the sequence is neither arithmetic nor geometric sequence since the terms of the sequence are prefect squares.

All I need is the slope and the equation also the y-intercept to help please!
Answer:
1) Slope; -10
Y-intercept; (0,60)
Equation; y=−10x+60
2) Slope;-1/2
Y-intercept; (0,0)
Equation; y=−1/2x
Step-by-step explanation:
Use the slope formula and slope-intercept form y=mx+b to find the equation.
Answer:
1.)
slope: -10
y-intercept: 60
equation: [tex]y=-10x+60[/tex]
2.)
slope: [tex]-\frac{1}{2}[/tex]
y-intercept: 0 (the line passes through the origin)
equation: [tex]y=-\frac{1}{2} x[/tex]
Explanation:
To find your slope you can use the equation [tex]\frac{y_{2}-y_1 }{x_2-x_1}[/tex], plugging in the designated numbers from two ordered pairs you select from the chart.
Your y-intercept is the value found at y whenever x is equal to 0.
For your equation, you simply place your slope in front of x and add on your y-intercept.
