WHICH EXPRESSION IS EQUIVALENT TO 3(x-2)
The expression 3(x-2) is equivalent to 3x - 6.
When you distribute the 3 to the term inside the parentheses, you multiply 3 by x and by -2, resulting in 3x - 6.
This is because the distributive property states that for any real numbers a, b, and c, the expression a(b+c) is equivalent to ab + ac. In this case, we have a = 3, b = x, and c = -2, so we can apply the distributive property and get 3x - 6.
You can also think of it as 3 multiplied by (x-2)
3x - 32 = 3x - 6
the graph below represents a linear function. which of the following equations models the linear graph above? please answer and explain why you chose the answer. i will mark you brainliest
D. Y= 4/3 (x)+4
The first step i did was finding C for the standard form equation of a linear function which is:
y=mx+c
Finding C is easy because C is simply the y-intercept(The point that crosses the y axis) which we can see from the graph is 4.
That allowed me to isolate possible answers of B and D because they contain a C which is equal to 4.
To determine which equation it was, i substituted an X coordinate to see if i got the correct Y coordinate from the graph.
Lets try B first and substitute the coordinate -3:
3/4 ×(-3)+4=1.75
As we see thats incorrect because the coordinate on the graph is (-3;0).
So we can conclude it is not b, however lets try D.
4/3 (-3)+4=0.
We see that this equation gives us the correct answer.
So therefore the correct equation is D
4/3 (x)+4

The value of a and b for the given quadrilateral to be a parallelogram is a = 16 and b = 4.
What is parallelogram?A quadrilateral having two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side. 360 degrees is the sum of all interior angles.
A parallelepiped is a three-dimensional shape with parallelogram-shaped faces.
We know that the opposite sides of a parallelogram are equal in length so we can equate the two sides as follows:
For a:
2a + 6 = 3a -10
Isolate the value of a by moving all the values having a to one side:
2a + 6 = 3a -10
3a - 2a = 6 + 10
a = 16
For b:
6b - 3 = 5b + 1
Isolate the value of b by moving all the values having b to one side:
6b - 3 = 5b + 1
6b - 5b = 1 + 3
b = 4
Hence, the value of a and b for the given quadrilateral to be a parallelogram is a = 16 and b = 4.

How can you compute depreciation mathematically?Identify the asset's cost. Get the asset's total depreciable value by deducting the projected salvage value from the asset's purchase price. Determine the asset's useful life. The annual depreciation amount is obtained by dividing the sum of steps (2) and (3) by the figure determined in steps (3).
Depreciation is the practice of deducting the cost of a company asset over a number of years as opposed to just one. There are four primary ways to depreciate assets: linear, twofold declining, sum of the years' digits, and manufacturing units.
As it is given, 1% of left tree is decaying every year.
Number of tree left after 8 years.
A = P{1-R/100}^ = 10M{1-1%/100}^

1) Evaluate the integral taking omega is the triangle formed by the x-axis 2y=x and x=2 (6e^(x^2))
2) Find the volue of the solid bounded by the coordinate planes and (1/3)x+(1/2)y+(1/4)z=1
The volume of the solid is 4π([tex]\frac{19}{6}[/tex]) and the integral of the f(x) , the line 2y=x, and x=2 is 3([tex]e^{4}[/tex] -1).
What is integral ?
An integral is a mathematical concept that is used to calculate the area under a curve or the total amount of change in a variable over a certain interval.
1)The first step is to find the intersection of the lines 2y=x and x=2. They will intersect at (2,1).
The second step is to find the intersection of the lines 2y=x and x=0. They will intersect at (0,0).
The third step is to find the integral over the region.
∫∫ (6e^(x^2))dxdy = ∫[0,2] (6e^(x^2))dx ∫[0,x/2] dy = ∫[0,2] (6e^(x^2))dx (x/2) = [3e^(x^2)] at [0,2] = 3e^(4) - 3e^(0) = 3(e^4 -1).
2)To find the volume of this solid, we can use the method of cylindrical shells.
we can find the function of the surface (1/3)x+(1/2)y+(1/4)z=1
by using cylindrical coordinates:
x = rcosθ , y = rsinθ , z = z
and substitute them in the equation (1/3)x+(1/2)y+(1/4)z=1
(1/3)rcosθ+(1/2)rsinθ+(1/4)z=1
(1/3)r(cosθ+2sinθ)+(1/4)z=1
z = 4(1-(1/3)r(cosθ+2sinθ))
V = ∫∫∫ 4(1-(1/3)r(cosθ+2sinθ)) rdrdθdz = 4π ∫[0,3] (1-(1/3)r(cosθ+2sinθ)) r^2 dr = 4π ∫[0,3] (1-r+(2/3)r^2) dr = 4π(3 - (3/2) + (2/3)) = 4π(19/6).
Hence , The volume of the solid is 4π([tex]\frac{19}{6}[/tex]) and the integral of the f(x) , the line 2y=x, and x=2 is 3([tex]e^{4}[/tex] -1).

Decrease 120% by 15%
By simply dividing the reduced value by 12, the value of 120 decreases by 12%, yielding a percentage drop of 102.
what is percentage ?In mathematics, a ratio or number expressed as a fraction of 100 is called a percentage. Also occasionally used are the acronyms "pct.," "pct," and "pc." However, the percentage symbol "%" is widely used to represent it. The % quantity is dimensionally empty. Basically, percentages are fractions when the denominator is 100. A percent symbol (%) should be placed next to a number to indicate that it is a percentage. For instance, you score a 75% on a test if you properly answer 75 out of 100 questions (75/100). When calculating percentages, multiply the result by 100 after dividing the amount by the total. By multiplying (value/total) by 100%, the percentage is determined.
given
The value of the percentage decrease
= · 120 - (15% × 120)
= 120 - 15% × 120
= 85 ÷ 100 × 120
= 85 × 120 ÷ 100 = 102
You may calculate the percentage drop by simply dividing the lowered value by the original value and multiplying the result by 100.
In this case, Reduced Value equals Original Value - New Value.
By simply dividing the reduced value by 12, the value of 120 decreases by 12%, yielding a percentage drop of 102.

The value of B, the area of the base, is 1,540 m^2.
What is value?Value is the relative worth, merit, or importance of something. It can refer to an intangible concept such as a person's principles or a tangible object such as a rare coin. Values vary widely across cultures, societies, and individuals, and can even vary within the same individual over time. Value is often used to describe the worth of something in terms of its usefulness, beauty, or desirability. Value can also refer to the moral or ethical standards of a person or group.
The area of the base can be found by using the formula A = V/h where A is the area of the base, V is the volume, and h is the height. In this case, A = 26,214 / 17 = 1,540 m^2. Therefore, the value of B, the area of the base, is 1,540 m^2.

We refer to two vectors as being orthogonal if they are perpendicular to one another. So these vectors' dot product will be zero. Let the given three vectors be [tex]\vec{u}[/tex], [tex]\vec{v}[/tex], and [tex]\vec{w}[/tex]. And the unknowns be a, b, c, d, and e.
Then, the vectors are written as

First, take [tex]\vec{u}[/tex] and consider unit length, we get,
[tex]1=\sqrt{(-0.6)^2+(0.8)^2+a^2}\\1=1+a^2\\a=0[/tex]
For [tex]\vec{v}[/tex], we get,
[tex]1=\sqrt{(b)^2+(c)^2+1^2}\\1=1+b^2+c^2\\b=0\;\text{and}\;c=0[/tex]
We know that [tex]\vec{w}[/tex] is orthogonal to both vectors, then,[tex]\vect{w}\cdot{\vec{v}=0[/tex]. Substituting, the values of [tex]\vec{v}[/tex] and [tex]\vec{w}[/tex], we get,
[tex]\begin{aligned}\langle d, -0.6, e\rangle \;\cdot\;\langle 0, 0, 1\rangle&=0\\e&=0\end{aligned}[/tex]
Also, [tex]\vect{u}\cdot{\vec{w}=0[/tex], Substituting, the values of [tex]\vec{u}[/tex] and [tex]\vec{w}[/tex], we get,
