The slope of the line that passes through the points (-2,5) and (1,4) is -1/3.

The slope of a line can be defined as the measure of the steepness of that particular line. If we were to define it mathematically, we would define it as the change in y-intercepts divided by the change in x-intercepts.

We know that the formula for finding the slope of a line is -

= m =  y₂-y₁/x₂-x₁ (i)

The given values are = x₁ = -2 ; x₂= 1 ; y₁= 5 ; y₂= 4

We use the given values and (i) to find -

= m = 4-5 / 1-(-2)

= m = -1/3

Hence, the slope of this line is -1/3.

The values of a and b are 6.83 and 1.17 respectively rounded to the nearest hundredth.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Let the numbers be a and b.

Given, (a + b) = 8..(i) and ab = 8.

Now,

(a + b)² = a² + 2ab + b².

64 = a² + b² + 16.

a² + b² = 48.

Now,

(a - b)² = a² + b² - 2ab.

(a - b)² = 48 - 16.

(a - b)² = 32.

(a - b) = 5.66...(ii)

Adding (i) and (ii) we get 2a = 13.66 ⇒ a = 6.83 and b = 8 - 6.83 ⇒ b = 1.17.

when two non-vertical lines are in the same plane and have the same slope,  they are said to be parallel lines. whereas the non-vertical lines are in the same plane and intersect at an angle of 90, they are said to be perpendicular.

A parallel lines is when two lines have the same slope, meaning they will never intersect. This is represented by the same "rise over run" ratio in the equation of the line. The perpendicular lines  is when two lines have a slope that is the opposite reciprocal of each other. This means that the lines will intersect at a 90-degree angle and can be represented by the equation y = -1/m * x + b, where m is the slope of one of the lines. Both of these concepts are important for understanding the basics of linear equations, as well as for determining the lines of best fit in graphs.

The Length of the tank is 19.28 cm

What is Surface area and volume ?

For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has.

According to question

We know that,

Volume of cuboid =Length × Breadth × Height

Now,

Volume of each brick

= 12×10×8 = 960 cm³

The ratio of the volume of water in the tank to the volume of the 6 brick = 9 : 8

Let the volume of water in the tank = x

Volume of the 6 brick = 6 × 960 cm³

= 5760 cm³

Therefore:

The volume of water in the tank / The volume of the 6 bricks  = 9/8

x/5760 = 9/8

x = 9/8 ×5760

x = 6480

Hence, the volume of water in the tank is 6480 cm³

Total Volume of the water tank = The volume of water in the tank  +  The volume of the 6 bricks

= 6480 + 960

= 7440 cm³

The base of the tank was square in shape

Length = Breadth

Therefore:

We know that,

Volume of cuboid

Length×Breadth×Height  =7440 cm³

Length×Length×Height = 7440

(Length)2 × 20 =7440

(Length)2 = 7440/20

(Length)2 = 372

Length = 3721/2

Length = 19.28 cm

Hence, length of tank = 19.287301… cm

The correct option for the area of the figure formed by a triangle and a parallelogram is 32 square millimeters.

To get the area of the figure, we solve for the area of the triangle and that of the parallelogram, and then add our results together.

area of a triangle is half the product of its base and height

area of parallelogram is the base multiplied by its height

the triangle has base = 8mm and height = 3mm

so

area of the triangle = (8mm × 3mm)/2

area of the triangle = 24mm²/2

area of the triangle = 12mm²

the parallelogram has base = 5mm and height = 4mm

so

area of the parallelogram = 5mm × 4mm

area of the parallelogram = 20mm²

Therefore, the area of the figure which is the sum of the area of the triangle and the area of the parallelogram is;

12mm + 20mm² = 32mm² or 32 square millimeters

3. We are given the point (1/3, 2). We can plug this into the equation as x1=1/3 and y1=2.

4. To find the slope (m), we need to calculate the rise over run. We can use the point (1/3, 2) and another point to calculate the slope.

5. Let's choose the point (0,0). The rise is 2 and the run is 1/3. So the slope (m) is 6.

Option C is correct, the set of side measurements that could be used to form a right-angle triangle is 5,12, and 13.

The side length of the triangle is shown in the option:

As we know,

Pythagoras' theorem is the square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.

Using Pythagoras' theorem:

From option(C):

5, 12 and 13

= (5) ² + (12) ² = (13) ²

= 25 + 144 = 169 (True)

Thus, the set of side measurements that could be used to form a right triangle is 5, 12, and 13 option (C) is correct.

An imperative theorem is a Pythagorean theorem, which states in any right triangle, the rectangle of the duration of the hypotenuse equals the sum of the squares of the lengths of the two different facets. If the hypotenuse has period c, and the legs have lengths a and b, then the theorem states that a² + b² =c²

The converse is real: if the lengths of the sides of a triangle satisfy the above equation, then the triangle has a right angle opposite side c.

some other facts about right triangles:

the acute angles of a right triangle are complementary.

= a + b+ 90°=180°

= a + b=90°

= a = 90° - b.

If the legs of a right triangle have the identical period, then the angles opposite those legs have the identical measure. considering those angles are complementary, it follows that every measure has 45 stages. via the Pythagorean theorem, the duration of the hypotenuse is the length of a leg times √2.

In a right triangle with acute angles measuring 30 and 60 degrees, the hypotenuse is two times the length of the shorter facet, and the longer side is the same as the length of the shorter side times √3:

= c = 2a

= b = a x √3.

The graph of a function can be sketched by plotting points.

First and foremost, it is to be determined if the function is odd/even or periodic. Next, we find the x and y intercepts. To sketch a graph of a function, one can start by plotting a few points that lie on the graph using the coordinates given by the function. For example, if the function is y = x², then points (0, 0), (1, 1), and (2, 4) can be plotted by substituting the values of x into the function to find the corresponding values of y.

Subsequent to this, one can connect the points with a smooth curve to form the graph of function. If the function is a straight line, the graph will be a straight line. If the function is quadratic, the graph will be a parabola. The graph may take on a more complicated shape for more complex functions.
