Answer:
AB=10
AB=7.2
Step-by-step explanation:
AB= √{(9-1)²+(8-2)²} = √{8²+6²}=√{64+36}=√100 =10
AB= √{(6-2)²+(2-8)²} = √{4²+(-6)²}=√{16+36}=√52 =7.2
The distance between points A(1, 2) and B(9,8) is 10 and the distance between points A(2, 6) and B(8, 2) is 7.2.
What is a coordinate plane ?A coordinate plane is a plane in which a set of two number lines are represented, horizontal line is called x-axis and vertical line is called y-axis.
In the first coordinate plane,
The coordinate of point A is (1, 2) and coordinate of point B is (9,8),
To find distance, use distance formula between two points (x₁, y₁) and (x₂, y₂) is [tex]\sqrt{(x_2 - x_1)^2+ (y_2 -y_1)^2)}[/tex]
Thd distance between A(1, 2) and B(9,8),
AB= [tex]\sqrt{{(9-1)^2+(8-2)^2}}[/tex] = [tex]\sqrt{{8^2+6^2}}[/tex]=[tex]\sqrt{{64+36}}[/tex]=[tex]\sqrt{100}[/tex] =10
In the second coordinate plane,
The coordinate of point A is (2, 6) and coordinate of point B is (8, 2),
To find distance, use distance formula between two points (x₁, y₁) and (x₂, y₂) is [tex]\sqrt{(x_2 - x_1)^2+ (y_2 -y_1)^2)}[/tex]
The distance between A(2, 6) and B(8, 2),
AB= [tex]\sqrt{{(8-2)^2+(2-6)^2} }[/tex]= [tex]\sqrt{6^2+(-4)^2}}[/tex]=[tex]\sqrt{{36+16}}[/tex]=[tex]\sqrt{52}[/tex] =7.2

What is least amount of surface area possible on a rectangular prism with a volume of 64 cubic inches? What are the dimensions of this rectangular prism?
Answer: 64=s3
Step-by-step explanation: V=s3
64=s3
find the cubic root of each side
3√ 64=s4=s
so the side of the cube is 4 cu in.
The surface area of a cube is
SA=nA
where SA
is surface area, n
is the number of faces, and A
is the area of one face.
Te area of one face (A) is s2 so

HELP PLEASE. What is true about the domain and range of the function?
O The domain is all real numbers less than or equal to

O The domain is all real numbers such that -3 sxs1,
and the range is all real numbers less than or equal to
4.
O The domain is all real numbers, and the range is all
real numbers less than or equal to 4.
O The domain is all real numbers less than or equal to
4, and the range is all real numbers.
Answer:
Step-by-step explanation:
This equation is y=4-(x+1)^2, there is no restriction upon x and y has a max value of four and approaches negative infinity as x moves away from -1 in either direction. So the domain is all real numbers and the range is all real numbers less than or equal to four.
The domain and range of the quadratic function are:
Domain: Set of all real numbers.Range: y ≤ 4.How to get the domain and range?
For a function y = f(x), we define the domain as the set of the possible inputs x, and the range is the set of the possible values y.
On the graph, we can see a quadratic function.
For the domain, we usually start assuming that the domain is the set of all real numbers, and then we remove problematic points. Where a problematic point can be a zero on a denominator or something like that.
In the case of a quadratic, there are no problematic points, then the domain is the set of all real numbers.
For the range, we can see that the function has a maximum at y = 4, and then it goes down, so the range is just:
R: y ≤ 4.

Answer:
x = 132º
Step-by-step explanation:

x = 132º
3. Which figure is a reflection of A over the x-axis? *
Answer:
triangle E
Step-by-step explanation:
imagine the X-axis as a mirror, the mirror reflects the shape or the body, and you'll see that the same distance you're away from the mirror as your reflection distance
if you want to prove that the triangle E is the reflection of the triangle A, count from the nearest point from the X-axis, you'll count 3 to reach the X-axis ,and the difference will be also 3 from the X-axis to the nearest point to the triangle E
A tank that holds up 10 gallons. when its active, a drain empties water from the tank at a constant rate, when Jada first see the tank, it contains 7 gallons of water. three minute later the tank contains five gallons of water.
At what constant/rate is the amount of water changing in the tank?
Answer:
-2/3 gallon/minute
Step-by-step explanation:
In three minutes the water volume has decreased by 2 gallons (7 less 5 is 2). The unit rate of decrease of the amount of water in the tank is thus:
- 2 gallons
------------------- = -2/3 gallon/minute

Answer:
< F would be 140 degrees
Step-by-step explanation:
So what you would do is that since they told you angle D is 40 degrees and you know that the 2 lines in there are parallel, and since they are asking for angle F, whne you add angle F and angle H they should equal 180 degrees which you know so you just subtract 40 degrees from 180 and you get 140 degrees which if angle F and you can subtract 40 since angle H and angle D would be congruent.
Help please.
Is algebra.
Answer:
3
Step-by-step explanation:
To find the average rate of change, we can use the formula: (y2-y1) / (x2-x1).
Let (15, 45) be (x1, y1) and (29, 87) be (x2, y2).
So we have: (87-45) / (29-15)
This can be simplified to: 42/14, or 3.

An online furniture store sells chairs for $150 each and tables for $400 each. The store must sell a minimum of $4900 worth of chairs and tables each day. Write an inequality that could represent the possible values for the number of tables sold, tt, and the number of chairs sold, cc, that would satisfy the constraint.
Answer: 150c + 400t ≥ 4900
Step-by-step explanation:
Let the number of chairs sold = c
Let the number of tables sold = t
Price for each chair = $150
Price for each table = $400
The inequality that could represent the number of tables and chairs sold will be:
(150 × c) + (400 × t) ≥ 4900
150c + 400t ≥ 4900
