Answer:
To find out if a point is inside, on, or outside a circle, we need to substitute the ordered pair into the equation of the circle:
(x-xc)^2+(y-yc)^2=r^2
where (xc,yc) is the centre of the circle, and r=radius of the circle.
If the left-hand side [(x-xc)^2+(y-yc)^2] is less than r^2, then point (x,y) is INSIDE the circle. If the left-hand side is equal to r^2, the point is ON the circle.
Finally, if the left-hand side is greater than r^2, the point is OUTSIDE the circle.
For the given problem, we have xc=3, yc=0, or centre at (3,0), r=sqrt(49)=7
(x-xc)^2+(y-yc)^2=r^2 => (x-3)^2+y^2=7^2
A. (-1,1),
(x-3)^2+y^2=7^2 => (-1-3)^2+1^2=16+1=17 <49 [inside circle]
B. (10,0)
(x-3)^2+y^2=7^2 => (10-3)^2+0^2=49+0=49 [on circle]
C. (4,-8)
(x-3)^2+y^2=7^2 => (4-3)^2+(-8)^2=1+64=65 > 49 [outside circle]

How do the slopes and y–intercepts of the two equations compare?.
The two equations with slope and y-intercept are compared as the lines may be intersecting, parallel, and coincident.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
Let the two equations in the form of slope and y-intercept.
[tex]\rm L_1: y = m_1x +c_1\\\\L_2: y = m_2x +c_2[/tex]
There are three cases are as follows;
Case 1 - If lines are intersecting then the slope of both equations will be different.
Case 2 - If lines are parallel then the slope of lines are same but the intercept will be different.
Case 3 - If lines are coincident their slope and the intercept will be the same.

Answer:
The probability of picking a 7 as the first card is 4 out of 52 or 1/13. The probability of picking a 5 as the second card is 4 out of 51. For both to happen, we multiply and get about .00603318

Graph g(x)=5|x -6|+2g(x)=5∣x−6∣+2g, left parenthesis, x, right parenthesis, equals, 5, vertical bar, x, minus, 6, vertical bar, plus, 2.
The graph of the absolute value function can be seen at the end of the answer. There we see a translated and dilated parent function.
How to graph the absolute value function?Here we want to graph:
g(x) = 5*|x - 6| + 2
First, remember that the minimum of the absolute value part |f(x)| is 0, so the minimum of the above function is 2, and that happens when x = 6. That will be the vertex of our function.
From that point, we will have two lines, one that goes to the right with a slope of 5, and the other that goes to the left with slope of -5 (the coefficient that multiplies the absolute value part of the function).
The graph of the function can be seen below.

Note: I will be writing these in slope-intercept form.
[6] y = 2x + 4
Since the line is going from bottom left to top right, we know the slope of the line is positive.
-> The b, or y-intercept, is 4 because the line hits the y-axis at 4.
-> The slope can be found with change in y over change in x,
[tex]\frac{14-4}{5-0} =\frac{10}{5} =2[/tex]
-> The final equation is y = 2x + 4
[7] y = -3x - 5
Because the line is going from top left to bottom right, we know the slope of the line will be negative.
-> The b, or y-intercept, is -5 because the line hits the y-axis at -5.
-> The slope can be found with change in y over change in x,
[tex]\frac{4--5}{-3-0}=\frac{4+5}{-3-0}=\frac{9}{-3}=-3[/tex]

find the length of the diameter of circle 0
Answer:
Diameter = 19.33
Step-by-step explanation:
Imaging a radius line from O to the endpoints of the 7. call this line R.
Label the part of the vertical line from O to the 90 degree intersection y.
Now you have a right triangle.
Using the Pythagorean theorem:
R² = 7² + y²
also
y = R - 3
substitute for y:
R² = 49 + (R-3)²
R² = 49 + R² - 6R + 9
simplify:
0 = 58 - 6R
6R = 58
R = 9.6667
Diameter = 2(9.6667) = 19.33

Answer:
$22,320
Step-by-step explanation:
1. Understanding
Mean is the average of a given set
2. Solving
We have to find the average of all of these numbers.
How do I find the average?
I add all of the numbers and divide by the number of numbers I added. Example:
(x + x + x + x)/4 or,
(x+x)/2 and examples in numbers:
(3+4)/2 or,
(9+4+8+5+7)/5
See what I mean? Dividing by the number of numbers I have.
Ok, now we know that, we can solve!
Here is the equation for this problem:
(24,600+19,000+33,000+15,000+20,000)/5 (We have 5 numbers)
We have to do Parentheses First
(24,600+19,000+33,000+15,000+20,000)/5 --> 111,600/5
111,600/5 = 22,320
22,320 is the average number of all of the numbers, which is the mean

x = 14
Step-by-step explanation:
x + 96 + 5x = 180
6x + 96 = 180
6x = 84
x = 14
Answer:
[tex]\huge\boxed{\sf x = 14}[/tex]
Step-by-step explanation:
x + 96 + 5x = 180 (Angles on a straight line)
Combine like terms
x + 5x + 96 = 180
6x + 96 = 180
Subtract 96 to both sides
6x = 180 - 96
6x = 84
Divide both sides by 6
x = 84 / 6
x = 14

A theater has 15 seats in the front row. The number of seats in each row follows an arithmetic series with 72 seats in the last row. The theater has a total of 870 seats. How many rows does the theater have? By how many seats does each row increase? Please show all work.
Step-by-step explanation:
Given:
Theater has 15 seats
Last Row has 72 seats.
Theater has a total of 870 seats.
Unknown: Number of rows
Number of seats in each row.
Equations: Since we know the total number of seats the Theater has we can use the sum of arithmetic series
[tex]s = \frac{a _{1} + a _{n} }{2} n[/tex]
Where a1 is the first row of seats
s is total number of seats
an is last row of seats
n is number of rows.
[tex]870 = \frac{15 + 72}{2} (n)[/tex]
[tex]870 = \frac{87}{2} n[/tex]
[tex]2(870) = 87n[/tex]
[tex]20 = n[/tex]
So we have 20 rows.
To find how many seats does each row increase, we use this formula,
[tex]a _{n} = a + (n - 1)d[/tex]
Let use the 20th row as an example,
[tex]a _{20} = 15 + (19)d[/tex]
[tex]72 = 15 + (19)d[/tex]
[tex]57 = 19d[/tex]
[tex]3 = d[/tex]
So the common difference is 3.
So the seats of each row increase by 3.

An engineer is tasked with doubling the length and width of a city park. The engineer draws the park on a coordinate plane and labels it ABCD. Find the area of the park before and after the expansion. A coordinate plane with Square A B C D plotted. Point A is at zero comma three. Point B is at thee comma three. Point C is at three comma zero, Point D is at zero comma zero. A photo of a park with a caption that says, dimensions of park are being doubled. What is the area of the park before the expansion?
The vertex coordinates of the park the engineer draws, A(0, 3), B(3, 3),
C(3, 0), D(0, 0) give the area of the park before expansion as 9 unit².
How can the area of the park be found?
The shape of the park = A square
The vertices of the park = ABCD
The coordinates of the point are; A(0, 3), B(3, 3), C(3, 0), D(0, 0)
The length of side AB = 3 - 0 = 3
Length of side BC = 3 - 0 = 3
Length of side CD = 3 - 0 = 3
Length of side AD = 3 - 0 = 3
Therefore, the park is a square with side length, s = 3 units
The area of a square, A = Side × Side = s²
The area of the park before expansion, A = 3 unit × 3 unit = 9 unit²

Answer:
side AB = [tex]9\sqrt{2}[/tex]
hypotenuse CB = 18
Step-by-step explanation:
with a 45-45-90 triangle, we know that the two legs (AC and AB in this picture) are the same length, so if AC is [tex]9\sqrt{2}[/tex] , then AB would have to be the same so therefore it would also be [tex]9\sqrt{2}[/tex]. We also know that the length of the hypotenuse (CB) is the length of the leg times [tex]\sqrt{2}[/tex]. So, it would be [tex](9\sqrt{2} ) *\sqrt{2}[/tex], which is the same as saying [tex]9*(\sqrt{2}) * (\sqrt{2} )[/tex]. Doing [tex](\sqrt{2}) * (\sqrt{2} )[/tex] would cancel out the square roots, leaving you with just 2, so you get 9*2, which is 18.
