The correct line of best fit is y = -1/3x + 2. Option C

A line of best fit is a line that is used to approximate the underlying pattern or relationship between two variables in a scatterplot. The line of best fit is drawn so that the number of points above the line and below the line are approximately equal (and the line passes through as many points as possible).

The line of best fit is used to make predictions about the response variable based on the predictor variable, and to understand the strength and direction of the relationship between two variables.

The equation that represent the value of the computer in years is: computer cost at (n-1) year - 1/5 (n-1cost) and the computer be worth less than $100 at 10 year

They are the set of numbers and symbols that are related by the different mathematical operation signs such as addition, subtraction, multiplication, division among others.

According to the data problem,

The cost of computer = $ 800

It lost 1/5 of value every year.

The value of computer after 0 years = cost of computer = $ 800

The value after 1 year = 800 - (1/5*800) = $640

The value after 2 years = 640 - (1/5*640) = $512

The value after 3 years = 512- (1/5*512) = $409.6

Continue with the formula we have:

The value after 9 years = 134.21 - (1/5*134.21) = 107.37

The value after 10 years = 107.37 - (1/5*107.37) = 85.90

The value after n years = computer cost at (n-1) year - 1/5 (n-1cost)

The percent change of the data set is 10%.

Percentage change is a way to describe the difference between an old value and a new value, expressed as a ratio and then multiplied by 100.

If the price of a product was $5 last month and it increased to $5.50 this month, we can calculate the percentage change as

=> (5.50 - 5) / 5 x 100 = 10%.

This means that the price of the product has increased by 10% compared to last month. If the price had gone down, we would have a negative percentage change.

Percentage change is a useful tool to compare data sets, especially when dealing with large numbers.

30x2 is 60 so on the first box u put 2. Then u multiply again 30x2 which is 60 so u put the 60 on the box below the 76. U subtract

Next, you would subtract it which would turn out to be 16. Since 16 can't go in 30 equally, u would drop down the 2 in the 762 now you can do 30 into 162 which is 5 times bc 30x5 is 150 and doesn't go over so u put the 5 in the box next to the 2.

30x5 is 150, u put that in the box below 162. Then u subtract 162-150 which is 12. So you have a remainder of 12.

In nature, there are various constraints on population number and expansion. Some are depending on the density, whereas others are not.

A population's per capita growth rate changes—typically declines—with rising population density due to density-dependent limiting constraints. One illustration is how individuals in a group compete for scarce food.

Independent of population density, several factors impact the per capita growth rate. Natural catastrophes like forest fires are examples.

Diverse limiting variables can combine in intricate ways to generate different patterns of population expansion. Some populations exhibit cyclical oscillations, where the population size varies cycle by cycle in a predictable manner.

The particle is speeding up over the time interval (10/6, ∞).

The particle is speeding up when its acceleration is positive, which occurs when its second derivative is greater than 0. The second derivative of x (t) is 6t - 10, so the particle is speeding up when t > 10/6. Therefore, the particle is speeding up over the time interval (10/6, ∞).

To calculate this, we take the second derivative of x (t):

x''(t) = 6t - 10

We then set this equal to 0 and solve for t

6t - 10 = 0

t = 10/6

Recall that the general form of the equation of a straight line in two dimensions is

++=0.

This can also be written in the form 

=+, where  is the gradient and  is the -intercept, which we can determine by knowing two points on the line.

If (,) is a point that lies on the line, we can determine  from the general form as =−(+); thus, the equation of the line can be written as

+−(+)=0.

The equation of the line can also be realized as a dot product of two vectors as (,)⋅(−,−)=0.

Now, if we define the position vectors,⃑=(,),⃑

then the equation of the line can be written in vector form as⃑ ⋅⃑=⃑⋅⃑,where ⃑=(,) is called a normal vector of the line and ⃑−⃑ will lie completely on the line.

A property of the dot product states that two vectors are perpendicular to each other if their dot product is zero. This equation of the line in vector form shows that the normal vector ⃑ and the vector ⃑−⃑ are perpendicular to each other by this property.

The general equation of a plane in three-dimensional space can be represented as Ax + By + Cz = D.

What is the plane?

A plane is a two-dimensional doubly ruled surface spanned by two linearly independent vectors. The generalization of the plane to higher dimensions is called a hyperplane. The angle between two intersecting planes is known as the dihedral angle.

Where A, B, and C are coefficients and D is a constant.

The coefficients A, B, and C represent the components of the normal vector to the plane, and D represents the distance of the plane from the origin.

In order to find the intervals where function f(x) = eˣ Cos(x) is increasing and where it is decreasing, we find the points where the derivative of the function, f'(x), is positive and negative,

The derivative of function : f(x) = eˣ cos(x) is:

⇒ f'(x) = eˣ cos(x) + eˣ (-sin(x))

⇒ eˣ (cos(x) - sin(x))

So , To find the intervals where f'(x) is positive or negative, we can use the sign of the derivative to determine if the function is increasing or decreasing.

we  know that ;

⇒ When f'(x) > 0, the function is increasing.

⇒ When f'(x) < 0, the function is decreasing.

For function  " eˣ (cos(x) - sin(x)) " ,

we can see that f'(x) is positive when cos(x) > sin(x) and negative when cos(x) < sin(x).

By using a unit circle, we can see that the inequality cos(x) > sin(x) is satisfied for x in the interval (0, π/4) U (7π/4, 2π), and

Orthogonal Planes in Space: In three-dimensional space, a plane is said to be orthogonal to another plane if the two planes are perpendicular to each other, i.e., their normal vectors are perpendicular. Since the normal vectors of two orthogonal planes are perpendicular to each other, this means that the angle between them is equal to 90 degrees.

mrs. utley's class has a ratio of 5/7.

5/7 = 0.714285714...

so, the class of mrs. Utley had a greater ratio.

to compare the ratios (like any fraction) within calculating their decimal value, we need to bring them to the same denominator :

Where A, B, and C are indeed the angles and A, B, and C are the angles' opposing sides.

∠ A = 43 ∘ , ∠ C = 75 ∘ , b = 15 ;
