Answer:

78m^3

Step-by-step explanation:

basically you have to split it into two rectangles and add the volumes

so think of it like this (first picture)

- looking at the bigger rectangle (blue rectangle) the 6 and the 4 are there as hints to the smaller rectangle so just kind of disregard them

- basically the bottom length is 6 but the top length is 5 and this is because the bottom length includes the other rectangle (smaller/pink rectangle), meaning the extra length from the other rectangle (smaller/pink rectangle) is 1.

- then height is given as 4 and 5. the height of 4 is caused by the line stopping when it meets the pink/smaller rectangle, meaning that the height from the other rectangle (smaller/pink rectangle) is 1.

- so using the correct measurements, the height is 5, the length is 5, and the width is 3 so:

5 • 5 • 3 = 75

~ so as stated above from evaluating the different measurements and how the rectangles “intersect” or meet:

the height is 1, the width is 1, and the length is then given as 3 so:

1 • 1 • 3 = 3

so then 75 + 3 = 78

so the full volume is 78 m^3

hope this helps :)

The following data table for two distinct linear functions utilizing identical x values for both functions is displayed:

[tex]\begin{tabular}{|c|c|c|}$\mathrm{x}$ & $\mathrm{y}=2 \mathrm{x}+7$ & $\mathrm{y}=-\mathrm{x}+4$ \\$-3$ & $2(-3)+7=-6+7=1$ & $-(-3)+4=3+4=7$ \\$-2$ & $2(-2)+7=-4+7=3$ & $-(-2)+4=2+4=6$ \\$-1$ & $2(-1)+7=-2+7=5$ & $-(-1)+4=1+4=5$ \\0 & $2(0)+7=0+7=7$ & $-(0)+4=0+4=4$ \\1 & $2(1)+7=2+7=9$ & $-(1)+4=-1+4=3$ \\2 & $2(2)+7=4+7=11$ & $-(2)+4=-2+4=2$ \\3 & $2(3)+7=6+7=13$ & $-(3)+4=-3+4=1$\end{tabular}[/tex]

The table demonstrates that the function y = 2x + 7 and the function y = -x + 4 both have values of 5 for x = -1.

As a result, the two functions' graphs will intersect at (1, 5)

First of all, we create 2 LINEAR function, i created the function f(x)=2x+5 and the function h(x)=3x+2, both are linear(without a quadratic term). Then

Choose a group of x values before creating the table. Add each x value from the left side column to the equation. To find the y value, evaluate the equation (middle column). Since the table of values really only contains x and y pairs, you can choose to omit the middle column from your table as an optional step.

you replace the x for a number:

Table 1 (F(X)=2X+5)                                 Table 2 (H(X)=3X+2)

X=1----->Y=2+5=7                                     X=1------>Y=3·1+2=5

X=2---->Y=2·2+5=9                                  X=2----->Y=3·2+2=8

X=3---->Y=3·3+5=11                                  X=3----->Y=3·3+2=11

With both tables of data we can see that in the X=3/Y=11 point this two linear functions will intersect so the answer is that the two functions will intersect at (3,11)----->(X,Y)

The quantity [tex](6\sqrt{x^5})^7[/tex] is transformed, into an expression with a rational exponent.

[tex]x^5 * 7 = 35[/tex]

This is further explained below.

Exponents are said to be rational if they are able to be represented in the form of p/q, where the value of q is less than 0.

The notation for rational exponents is often written as xm/n, where x represents the base (a positive integer) and m/n is the rational exponent. Exponents may also be represented as xmn=nxm x m n = x m n.

This is another way to express rational exponents.

Generally, the equation is mathematically given as

[tex](6\sqrt{x^5})^7[/tex]

TRIANGLE

A triangle is a three-sided polygon that is sometimes (but not always) referred to as the trigon.

Each triangle has three sides and three angles, with some of the angles being the same.

In the case of a right triangle, the side opposite the right angle is known as the hypotenuse, while the other two sides are known as the legs.

Trilateral Relationship of Triangle

A trilateral is a shape with three sides in geometry. 'Of trilateral figures, an equilateral triangle is one with three equal sides, an isosceles triangle is one with two equal sides, and a scalene triangle is one with three unequal sides.'

Triangle Inequality

The triangle inequality asserts that the sum of the lengths of any two sides of a triangle must be larger than or equal to the length of the remaining side in mathematics.

The condition of the triangle's sides

According to the triangle inequality, the lengths of any two triangle sides must be more than or equal to the length of the third side. Only a degenerate triangle with collinear vertices can have that total equal to the length of the third side.

If and only if the side lengths satisfy the triangle inequality, a triangle with three given positive side lengths exists.

The coordinates of the vertices of A'B'C' for the reflection are (7,1),(5,-7), and (-2,1) respectively.

A reflection is a transformation that uses a line to reflect a figure, much like a mirror. The mirror line is also known as the line of reflection.

The given coordinates are A(7,-5), B(5,3), and C(-2,-5).

The line of reflection is y = -2.

We have to determine the coordinates of the vertices of A'B'C' for the reflection.

In this case, the x-coordinate will remain the same and the y-coordinate will vary as the points are reflected across the line y = -2.

From the line of reflection i.e.y = -2, point A(7,-5) is located down at a distance of 3 units so its reflection A' is 3 units up of line y = -2 at (7,1).

From the line of reflection i.e.y = -2, point B(5, 3) is located up at a distance of 5 units so its reflection B' is 5 units down of line y = -2 at (5,-7).

From the line of reflection i.e.y = -2, point C(-2,-5) is located down at a distance of 3 units so its reflection C' is 3 units up of line y = -2 at (-2,1).

Hence, the coordinates of the vertices of A'B'C' for the reflection are (7,1),(5,-7), and (-2,1) respectively.
