A reflection point occurs when a figure is constructed around a single point known as the point of reflection or center of the figure. For every point in the figure, another point is found directly opposite to it on the other side.

According to the given question:

1. Reflection of point 1 over X axis (x, -y) ⇔ (x, y)

 ∴ Reflection of (-4, 2) over X axis is (-4, -2)

2. Reflection of point 2 over Y axis (x, y) ⇔ (-x, y)

 ∴ Reflection of (-2, 3) over Y axis is (2, 3)

3. Reflection of point 3 over x = 1

 ∴ Reflection of (-2, 1) over x = 1 axis is (2, 1)

4. Reflection of point 4 over y = x is  (x, y) ⇔ (y, x)

 ∴ Reflection of (-1, 2) over X axis is (2, -1)

one leg of a right triangle is 6 inches longer than the other leg, and the hypotenuse is 30 inches. Thus,

The lengths of the legs of the triangle are 18 inches,24 inches and  30 inches.

Three vertices make up a triangle, a three-sided polygon. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

Given that,

one leg of a right triangle is 6 inches longer than the other leg.

hypotenuse is 30 inches.

Let assume, the other leg be x

It is given that, one leg of a right triangle is 6 inches longer than the other leg. So, One leg = x + 6

Since it is a right angled triangle,

h² = p² + b²

Where, h = hypotenuse

p = perpendicular

B = Base

So, (30)² = (x+6)² + x²

or, x = -24, 18

As, the length of side cannot be negative so x becomes 18.

Thus, x + 6 = 18 + 6 = 24 inches

Hypotenuse = 30 inches

Hence, the lengths of the legs of the triangle are 18 inches, 24 inches and  30 inches.

Circumference of the circle is 37.68 feet

A circle's diameter is multiplied by to determine its circumference (pi). You can also determine the circumference by multiplying 2radius by pi (=3.14).

R is specified as 6 feet, with a diameter of 12 feet (2 x 6).

Circumference: 12 feet times 3.14 inches, or 37.68 feet

If r is equal to 6 cm, the circumference is given by c = 2 (6) = 12 cm. If you'd rather have a number, the solution is 37.7 cm, rounded to the closest tenth.

D is the diameter, which is equal to 2 times r in the circumference formula ( r is the radius).

What is simultaneous linear equation?

At first it is important to know about linear equation

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A one degree equation is known as linear equation.

Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.

Here, a simultaneous linear equation needs to be solved

Let the number of children be x and number of adults be y

481 people used the public swimming pool.

x + y = 481 ..... (1)

The daily prices are $1.75 for children and $2.00 for adults.
Total price = $(1.75x + 2y)

By the problem,

1.75x + 2y = 932.50

7x  + 8y = 3730 .... (2)

Multiplying (1) by 7

7x + 7y = 3367.... (3)

Subtracting (3) from (2)

y = 363

Putting the value of y in (1)

x  + 363  = 481

x = 481 - 363

Answer: 35%

Step-by-step explanation:

To find the sum of vectors u and v, we can add their components separately:

(u + v)x = (7cos 310° + 2cos 115°)

(u + v)y = (7sin 310° + 2sin 115°)

Using a calculator to evaluate these expressions, we get:

(u + v)x = -2.16

(u + v)y = 8.48

The magnitude of the sum vector u + v can be found using the Pythagorean theorem:

|u + v| = √((u + v)x^2 + (u + v)y^2)

= √(-2.16^2 + 8.48^2)

= √(72.3584)

= 8.51

The direction of the sum vector u + v can be found using the inverse tangent function:

θ = tan^(-1)((u + v)y / (u + v)x)

= tan^(-1)(8.48 / -2.16)

= tan^(-1)(-3.928571428571429)

= 143.13°

Rounding the magnitude to the nearest tenth and the direction to the nearest degree, we get:

u + v = 8.5 (cos 143°, sin 143°)

Therefore, the sum of vectors u and v is equal to 8.5 (cos 143°, sin 143°).

The distance Alex jumped and the distance Eric jumped compared with the state records indicates that the magnitude of Eric's score was closer to their grades state  record

The magnitude of a value is the value itself, indicating the distance of the number from zero.

Alex is an eight grader

Eric is a seventh grader

The distance Alex jumped = 39.75  feet

The distance Eric jumped = 37 feet 11 inches

The eight grade record = 42.25 feet

The seventh grade record = 39 feet 3 inches

Each athlete distance  jumped is compared with  the record for the grade at which they jumped

The deviation of the distance  jumped from the record scores are;

Alex's difference between distance jumped  and the record = 39.75 - 42.25 =  -2.5

The difference between the distance Eric jumped and the record =  37 feet + 11 inches - (39 feet + 3 inches)  =  -(1 feet + 4 inches)

Answer: I can confirm that Eric is closer!

Step-by-step explanation:

Option (a) is correct option.

The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality.

Constant ratio, constant rate, unit rate, constant of variation, and even rate of change are other names for the constant of proportionality. When two or more parameters are proportional to one another either directly or indirectly, their relationship is stated as a = kb or a = k/b, where k denotes the direction of the relationship between the two variables.The proportionality constant is thus k.

Constant of proportionality in given case is nothing but slope of given graph.

Slope is given by tangent of the angle made by line with positive x-axis.

p =slope of line

p = [tex]\frac{y-axis}{x-axis}[/tex]

p=[tex]\frac{140}{2}[/tex] = 70

Answer:

Step-by-step explanation:

There are 1000 milliliters in one liter, so a two-liter bottle contains 1000 * 2 = 2000 milliliters of milk. Since one cup contains approximately 250 milliliters, a two-liter bottle contains 2000 / 250 = 8 cups of milk. Rounding this value to the nearest tenth, we find that there are approximately 8.0 one-cup servings of milk in a two-liter bottle.

Answer:

write the equation in slope intercept form. Write the numbers in the equation as simplified proper fraction improper fraction or integer

The equation of the parallel line t is y = -4x  - 9.

The equation of line s is given as

y = -4x - 5/3

Also, from the question, the point on line t is given as Point = (-3, 3)

The equation of a line can be represented as

y = m x + c-------(1)

Where m represents the slope

c is the constant value

By comparing the equations, we have the following

m = -4

This means that the slope of y = -4x - 5/3 is -4

The slopes of parallel lines are equal

This means that the slope of the line t is -4

The equation of the parallel line is then calculated as:

y = m(x - x₁) +y₁

Where m = -4

(x₁, y₁) = (-3, 3)

Now, we should substitute the known values in the above equation(1)

y = -4(x + 3) + 3

The answer to this Question based on speed is 1m/s

What is speed?

Speed can be defined as the rate at which an object moves from one point to another. It is usually measured in units of distance per unit of time, such as kilometers per hour (km/h) or miles per hour (mph). Speed is a scalar quantity, meaning it has magnitude but no direction. Speed can also be thought of as the rate of change of position. When an object is in motion, its speed is constantly changing due to the force of gravity, air resistance, and other external factors. The speed of an object can be affected by its weight, shape, and size. An object's speed can also be affected by other factors such as the friction of the surface it is moving on and the wind or air resistance. Speed is an important concept in physics, engineering, and many other fields.

we are given that velocity as a function of time along a single direction

we write v(t) = -2t+5

hence speed = mod(velocity)

speed at t = 2 sec = mod (velocity at t = 2 sec)
