Step-by-step explanation:
From inspection of the graph:
center of the circle = (6, -4)radius = 4 unitsGeneral equation of a circle: (x - a)² + (y - b)² = r²
(where (a, b) is the center and r is the radius)
Therefore, substituting the given values into the equation:

What is the value of b in the equation y = mx + b if the slope is 5 and we have one ordered pair (2, 3)?
Answers
Step-by-step explanation:
the slope is always the factor of x.

Find the area of the trapezoid. The median is equal to 25cm and the height is 8cm. (btw if you explained how to find the base would help a lot) :)
Answers
The area of trapezium with a median of 25 cm and height of 8 cm = 200 cm².
What is the Area of a Trapezium?Area of trapezium = 1/2(a + b)h, where a and b are the parallel bases of the trapezium, and h is the height.
Note, median of a trapezium = half of the sum of the length of the two bases of a trapezium = 1/2(a + b). Therefore, the area of a trapezium with a given median would be:
A = median length × height

mary needs 50 ft of fence to protect her rectangular garden from squirrels. How long and how wide is the garden if the length is 8 ft more than the width
Answers
[tex]\bold{\huge{\underline{ Solution }}}[/tex]
Given :-Mary needs 50 ft of fence to protect her rectangular garden from squirrel The length of the garden is 8 ft more than the width To Find :-We have to find the length and breath of the rectangular garden Let's Begin :-Mary needs 50ft of fence to protect her rectangular garden from squirrel
Therefore,We can conclude that
The perimeter of the rectangular garden
[tex]\bold{ = 50\: ft}[/tex]
We know that,
Perimeter of the rectangle
[tex]\sf{ = 2( Length + Breath) }[/tex]
Here, we have Length of the garden that is 8ft more than the widthLet assume the width of the garden be x
According to the question
[tex]\sf{ Perimeter\:of\:rectangle = 2( x + 8 + x) }[/tex]
[tex]\sf{ 50 = 2( x + 8 + x) }[/tex]
[tex]\sf{ 50 = 2( 2x + 8)}[/tex]
[tex]\sf{ 50 = 4x + 16}[/tex]
[tex]\sf{ 50 - 16 = 4x }[/tex]
[tex]\sf{ 34 = 4x }[/tex]
[tex]\sf{ x = }{\sf{\dfrac{34}{4}}}[/tex]
[tex]\sf{ x = 8.5 }[/tex]
Thus, The breath of the garden is 8.5 ft
Therefore,The length of the garden
[tex]\sf{ = x + 8}[/tex]
[tex]\sf{ = 8.5 + 8}[/tex]
[tex]\sf{ = 16.5\: ft }[/tex]
Hence, The length and breath of the rectangle are 8.5ft and 16.5ft .
Given :
Mary needs 50 ft of fence to protect her rectangular garden from squirrels.The length is 8 ft more than the width of the garden.⠀
To Find :
The dimensions of the garden.⠀
Solution :
Let us assume the length of the garden as x ft and therefore, the width will become (x - 8) ft.We know that,
[tex]\qquad{ \sf{ \pmb{2(Length + Width ) = Perimeter_{(rectangle)}}}}[/tex]
⠀
Substituting the values in the formula :
[tex]{ \dashrightarrow\qquad{ \sf{2(x + x - 8 ) = 50}}}[/tex]
[tex]{ \dashrightarrow\qquad{ \sf{2(2x- 8 ) = 50}}}[/tex]
[tex]{ \dashrightarrow\qquad{ \sf{4x- 16 = 50}}}[/tex]
[tex]{ \dashrightarrow\qquad{ \sf{4x = 50 + 16}}}[/tex]
[tex]{ \dashrightarrow\qquad{ \sf{x = \dfrac{66}{4} }}}[/tex]
[tex]{ \dashrightarrow\qquad{ \bf{x = 16.5}}}[/tex]
Therefore,
The Length of the garden is 16.5 ft .⠀
[tex]{ \dashrightarrow\qquad{ \sf{Width_{(Garden)} = x - 8}}}[/tex]
[tex]{ \dashrightarrow\qquad{ \sf{Width_{(Garden)} = 16.5 - 8}}}[/tex]
[tex]{ \dashrightarrow\qquad{ \bf{Width_{(Garden)} = 8.5}}}[/tex]
⠀
Therefore,
The Width of the garden is 8.5 ft .⠀
Hence,

Answers
Answer:
18. The conjecture is: The product of two negative even integers is an even integer.
Testing: Let integers be -4 and -6. [Two negative even integers]
Then (-4) × (-6) = 24 [Even integer]
19. The conjecture is: Sum of two negative odd integers is a negative even integer.
Testing: Let the two negative odd integers be -3 and -7.
Then -3 + (-7) = -10 is a negative even integer
20. The conjecture is: Sum of two even integers and two odd integers is an even integer.
Testing: Let integers be 4, 12, 13, 17 (Two even integers and two odd integers)
Then 4 + 12 + 13 + 17 = 46 (Even integer)
21. The statement is: p------->q [If you ran 1 mile, then you ran 5280 feet]
Decide whether statement is true: So if p is True then q is also True.
Hence p------->q is True. So the given statement is True.
Step-by-step explanation:
18. The product of two negative even integers.
Let the integers be -2m and -2n, m and n are positive integers
Product in (-2m) × (-2n) = 4mn = 2(2mn)
= 2p, p = 2mn
The conjecture is: The product of two negative even integers is an even integer.
Testing: Let integers be -4 and -6. [Two negative even integers]
Then (-4) × (-6) = 24 [Even integer]
19. The sum of two negative odd integers.
Let the integers be -(2m + 1) and -(2n + 1), m and n are positive integers
Then -(2m + 1) + [-(2n + 1)] = -2m - 1 - 2n - 1
= -2m - 2n - 2
= -2(+m + 2 + 1)
= -2p, p = m + n + 1
The conjecture is: Sum of two negative odd integers is a negative even integer.
Testing: Let the two negative odd integers be -3 and -7.
Then -3 + (-7) = -10 is a negative even integer
20. The sum of two even integers and two odd integers.
Let the integers be 2m, 2n, 2p + 1, 2q + 1 (m, n, p, q are positive integers)
Then, 2m + 2n + 2p + 1 + 2q + 1 = 2(m + n + p + q + 1)
= 2r, r = m + n + p + q + 1
The conjecture is: Sum of two even integers and two odd integers is an even integer.
Testing: Let integers be 4, 12, 13, 17 (Two even integers and two odd integers)
Then 4 + 12 + 13 + 17 = 46 (Even integer)
21. Let p: You ran 1 mile
Let q: You 5280 feet
The statement is: p------->q [If you ran 1 mile, then you ran 5280 feet]
Since 1 mile = 5280 feet
So if p is True then q is also True.
Hence p------->q is True. So the given statement is True.

Haley has $155 in savings, and her brother Hank has $230. Hayley is saving $10 each week and her brother is spending $15 each week. After how many weeks will their savings account have the same amount of money in them?
Answers
Answer:
3 weeks
Step-by-step explanation:
Set the equations. Let "amount of weeks" be signified by the variable, x.
First, note that Haley starts with $155, and saves $10 each week:
10x + 155
Next, note that her brother has $230 saved and spends $15 each week:
230 - 15x.
Set the two equations equal to each other:
10x + 155 = 230 - 15x
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Divisions
Additions
Subtractions
~
First, subtract 155 and add 15x to both sides of the equation:
10x (+15x) + 155 (-155) = 230 (-155) - 15x (+15x)
10x + 15x = 230 - 155
25x = 75
Next, divide 25 from both sides of the equation:
(25x)/25 = (75)/25
x = 75/25 = 3
3 weeks is your answer.

Answers
Using proportions, it is found that the best estimate for the squirrel population is of 8000.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 43 squirrels out of 430 had tags. Considering that in the entire population, 800 are tagged, and we want to find the total population, the rule of three is given by:
43 tagged - 430 squirrels

the functions for cost and revenue, Then, predict the profit after 10 months of operation, found your answer to the nearest dollar. Provide
valid mathematical reasoning and calculations to support your answer,
Answers
The profit function of the business is the difference between the revenue and the cost functions
The equations of the cost and the revenue functions are: [tex]y = \frac 43x[/tex] and [tex]y = 0.5x + 3.5[/tex]The profit function is [tex]y = \frac 56x - 3.5[/tex]The profit after 10 months of operation is 29/6Part A: The equations to represent the functionsFor the revenue function, we have the following points
(x,y) = (0,0) and (6,8.0)
Since the line passes through the origin, the equation of the line would be:
[tex]y = \frac{y_1}{x_1} * x[/tex]
So, we have:
[tex]y = \frac{8.0}{6} * x[/tex]
[tex]y = \frac 43x[/tex]
For the cost function, we have the following points
(x,y) = (0,3.5) and (9,36) for x > 5
The equation of the line would be:
[tex]y = \frac{y_1-y_2}{x_1-x_2} * (x - x_1) + y_1[/tex]
So, we have:
[tex]y = \frac{6.5-3.5}{6-0} * (x - 0) + 3.5[/tex]
[tex]y = 0.5x + 3.5[/tex]
Hence, the equations of the cost and the revenue functions are: [tex]y = 0.5x + 3.5[/tex] and [tex]y = \frac 43x[/tex]
Part B: The profit functionThis is calculated as:
Profit = Revenue - Cost
So, we have:
[tex]y = \frac 43x - 0.5x - 3.5[/tex]
Evaluate the difference
[tex]y = \frac 56x - 3.5[/tex]
Part C: The profit after 10 months of operationSubstitute 10 for x in [tex]y = \frac 56x - 3.5[/tex]
[tex]y = \frac 56 * 10 - 3.5[/tex]
[tex]y = \frac {50}6 - 3.5[/tex]
Evaluate the difference
[tex]y = \frac {50-21}6[/tex]
[tex]y = \frac {29}6[/tex]
Hence, the profit after 10 months of operation is 29/6
