determine whether each function has line symmetry.
Answer: 1 and 3 dont 2 and 4 do have a line of symmetry
Step-by-step explanation:
Graphs 1, 3 function are not line symmetry and 2 and 4 have line symmetry.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The line of symmetry is an imaginary line that runs through the centre of a line or shape creating two perfectly halves.
To check a function to be symmetrical about the origin we need to replace y with minus y and x with minus x and the function must be equal to original function.
In the given graphs, 1 and 3 are not symmetrical and 2 and 4 are symmetrical.
Hence graphs 1, 3 function are not line symmetry and 2 and 4 have line symmetry.

If a 200 N net force acts on a 500 grams car, what will the acceleration of the car be?
Answer:
The acceleration of the car will be 400 m/s².
Step-by-step explanation:
The acceleration of the car can be found using Newton second law:
[tex] F = ma [/tex]
Where:
F: is the net force = 200 N
m: is the mass = 500 g
a: is the acceleration =?
Then, the acceleration will be:
[tex] a = \frac{F}{m} = \frac{200 N}{500 g*\frac{1 kg}{1000 g}} = 400 m/s^{2} [/tex]
Therefore, the acceleration of the car will be 400 m/s².

Answer:
all angles are 60 degrees
Step-by-step explanation:
since all sides are equal, all angles will be equal so its a equilateral triangle
all angles in a equilateral triangle are 60 as 180/3 is 60
so all angles equal 2x
2x = 60
x = 60/2 = 30

Lines AAA, BBB, and CCC show proportional relationships.
Which line has a constant of proportionality between yyy and xxx of 333?
The line A has the constant of proportionality between x and y as 5.
What do you mean by constant of proportionality?In mathematics, we use the constant of proportionality to determine the type of proportionality, whether direct or indirect.
The proportionality constant aids in the solution of equations encompassing ratios and proportions.If one quantity increases, other quantity increases, the two quantities are considered to be proportional. Furthermore, as one quantity decreases, so does the other.For, the data given in the question;
Given lines A, B, and C Obtaining the equation for the line yields the proportionality constant.
1) Line A intersects (0,0) and (1, 5). Line A's equation is given by:
y - y₁ = [(y₂ - y₁)/(x₂ - x₁)]×(x - x₁)
Substitute the values;
y - 0 = [(5 - 0)/(1 - 0)]×(x - 0)
y = 5x
y/x = 5
The proportionality constant between y and x is 5.
2) Line B traverses (0,0) and (3, 5). Line A's equation is given by:
y - y₁ = [(y₂ - y₁)/(x₂ - x₁)]×(x - x₁)
Substitute the values;
y - 0 = [(5 - 0)/(3 - 0)]×(x - 0)
y = 5x/3
y/x = 5/3
The proportionality constant between y and x is 5/3.
3) Line C intersects (0,0) and (3, 2). Line A's equation is given by:
y - y₁ = [(y₂ - y₁)/(x₂ - x₁)]×(x - x₁)
Substitute the values;
y - 0 = [(3 - 0)/(2 - 0)]×(x - 0)
y = 3x/2
y/x = 3/2
The proportionality constant between y and x is 2/3.
Therefore, the constant of proportionality between x and y as 5 shown by line A.

5 small bucket and 2 large bucket of water make 20 liter.three small bucket and 2 large bucket make only 18 liter.how much water each bucket hold?
9514 1404 393
Answer:
small: 1 liter; large: 7.5 liters
Step-by-step explanation:
The difference between the two sets of buckets is 2 small buckets and 2 liters. Hence we know that a small bucket is 1 liter.
Then 5 small buckets contribute 5 liters to the 20-liter total. The remaining 15 liters comes from 2 large buckets, so each of those is 7.5 liters.
Large bucket: 7.5 liters
Small bucket: 1 liter

The expression equivalent to 4^-5 • 3^-5 is 12^-5
What are equivalent expressions?Equivalent expressions are simply known as expressions with the same solution but different arrangement.
Given the index expressions;
4^-5 • 3^-5
Using the exponent rule, the two values are have different bases but the same exponent and thus, we multiply the bases and leave the exponents the same way.
This can be written as;

Astrid is painting the outside of her cabin = 23 hours
Astrid has her two sons help if they each work at approximately the same rate as Astrid is 23/2 = 11.5
Then 11.5/2 = 5.75 hours.
The work is calculated using the work formula. Let's review what work means before learning the formula. When we apply a force to an item and the object is moved, we say that work has been done. The work done becomes zero if there is no displacement in the direction of the force. Calculating the amount of labor required to move an object is done using the work formula.
