A university designs its campus with a master plan of two concentric circles. All of the academic buildings are within the inner circle (so that students can get between classes in less than 10 minutes), and the outer circle contains all the dormitories, the Greek park, cafeterias, the gymnasium, and intramural fields. Assuming the center of campus is the origin, write an equation for the outer circle if the diameter is 3800 feet. Equation Editor
Answer:
[tex]x^2+y^2=36100000[/tex]
Step-by-step explanation:
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]

[tex]pg\int\limits^7_7(10-y)2\sqrt{7^2-y^2} \, dy[/tex]
*The last bound is negative 7
Then it equals 15085928 or 1.5E7
Step-by-step explanation:
[tex]x^2+y^2=7^2[/tex]
area = 2xdy
depth = (7+3)-y -> (10-y)
total force = [tex]pg\int\limits^7_7 {(10-y)2x} \, dy[/tex]
Substitute 2x from the first equation as x=[tex]\sqrt{7^2-y^2}[/tex]
total force = [tex]pg\int\limits^7_7 {(10-y)2\sqrt{49-y^2} } \, dy[/tex]
=pg1539.38
=(1,000)(9.8)(1539.38)=1.5E7 N
*Lower bound is -7, can't get the program to allow me to put it as a negative
The hydrostatic force against one side of the plate is an integral 1.5E7 N.
What is the equation of a circle at the origin?The general equation of a circle is [tex](x-h)^{2} +(y-k)^{2} = r^{2}[/tex]. The coordinate is (0, 0) at the origin, so the equation will become [tex](x)^{2} +(y)^{2} = r^{2}[/tex].
[tex](x)^{2} +(y)^{2} = 7^{2}[/tex]
area of circular plate = 2xdy
depth = (7+3)-y = (10-y)
The total force = [tex]pg\int\limits^7_7[ {10-y} ]2xdy[/tex]
Substitute 2x from the first equation as x = [tex]\sqrt{7^{2} -y^{2} }[/tex][tex]pg\int\limits^7_7[ {10-y} ]\sqrt{49 -y^{2} }dy[/tex]
= pg 1539.38
= (1,000)(9.8)(1539.38)
= 1.5E7 N
Thus, The hydrostatic force against one side of the plate is an integral 1.5E7 N.

b) f^-1 = [tex]\sqrt{x+1}[/tex]
c) 3
Step-by-step explanation:
Just plug the numbers in for x:
(5)^2 -1 = 24
Switch x and y then solve for y and replace y with f^-1(x):
x = y^2 -1
sqrt(x +1) = y = f^-1(x)
Now plug in 8:
f^-1(x) = sqrt(8 +1) = 3

Step-by-step explanation:
biked 139/8 saturday
biked 135/7 sunday
which fraction is greater by finding a common denominato 107/56r
Least common Denominator of 7 and 8 is 56
139x 7/8 x 7= 973/56
135x8/7 x 8=1080/56

Everglades National Park is 225 mi long. What scale is needed to draw a map of Everglades National Park that is 10 in. long?
A. 1 in. = 22.5 mi
B. 10 in. = 225 mi
C. 1 in. = 0.04 mi
D. 10 in. = 22.5 mi
Answer:
A. 1 in. = 22.5 mi
Step-by-step explanation:
Since 22.5 x 10 = 225, we can conclude that this will fit the scale needed. B. is incorrect because it is simply illogical in context with a scale and the question. C. is incorrect since 10 x 0.04 is 0.4, which does not equal 10. D. is incorrect since we need the scale to add up to equal 225 mi, not 22.5.

+3x−96, x, squared, plus, 3, x, minus, 9.
Your answer should be a polynomial in standard form.
Answer:
8x²- x -8
Step-by-step explanation:
The question is not well written. I guess what you mean is:
Subtract -2x^2+4x-1 ( minus 2x squared plus 4x minus 1) from 6x^2+3x-9 (6x squared plus 3x minus 9).
To subtract -2x^2+4x-1 from 6x^2+3x-9, that is
6x^2+3x-9 - (-2x^2+4x-1). This can be written as
6x²+3x-9 - (-2x²+4x-1)
Now, opening the bracket, we will get
6x²+3x-9 +2x²-4x+1
Then, collecting like terms, we get
6x²+2x²+3x-4x-9+1
6x²+2x² = 8x²
3x-4x = -x
-9+1 = -8
∴6x²+2x²+3x-4x-9+1 becomes
8x²-x -8
The answer is 8x²-x -8.
Simplified form of the polynomial :
8x²- x -8
Given(correct form of question):
Subtract -2x²+4x-1 ( minus 2x squared plus 4x minus 1) from 6x²+3x-9 (6x squared plus 3x minus 9).
Now,
To subtract -2x²+4x-1 from 6x²+3x-9, that is
6x²+3x-9 - (-2x²+4x-1). This can be written as
6x²+3x-9 - (-2x²+4x-1)
Now, opening the bracket, we will get
6x²+3x-9 +2x²-4x+1
Then, collecting like terms, we get
6x²+2x²+3x-4x-9+1
6x²+2x² = 8x²
3x-4x = -x
-9+1 = -8
∴6x²+2x²+3x-4x-9+1 becomes 8x²-x -8
Thus,
The answer is 8x²-x -8.

The point B (-2, 4) has been rotated by 270⁰ counter clock wise about the point (1, 3). Determine the coordinates for the point B’. 1.B' ( - 2, - 6) 2.B' ( - 2, 6) 3.B' ( 2, - 4) 4.B' ( 2, 6)
Answer:
The coordinates of the point B’ is (2,6)
Step-by-step explanation:
Let us have a case of rotation for 270 counterclockwise first;
So if we had;
(x,y) and we rotate 270 degrees about the origin, we will have (y , -x)
This is the case of the origin.
In cases where we are not rotating around the origin, say a point (a,b)
The result of the rotation will be;
(x,y) Turning to (y - b + a , a - x + b)
In the case of this question;
x = -2, y = 4
a = 1 , b = 3
Substituting these into the rotation equation, we have;
(4-3 + 1 , 1-(-2) + 3)
= (2 , 6)
So the coordinates of the point B’ is (2,6)

Dancing Pools sells swimming pools in 4 sizes. The small pool is 72 feet
long and 18 feet wide. The medium pool is 80 feet long and 20 feet wide. The
large pool is 88 by 22. If the new superduper Coffeetable pool is 96 feet long,
how wide will it be?
Answer:
24 feet wide
Step-by-step explanation:
72/18 = 4
80/20 = 4
88/22 = 4
Since there is one common answer between all sizes, you can make a ratio to help or you can use inverse operations.
Inverse operations is easier, so you would divide 96 by 4, and that will equal 24.
