8 is not a perfect number as sum of its proper divisors is not equal to 8.

A perfect number is a positive integer that is equal to the sum of its proper divisors, which are the divisors of the number excluding the number itself. In other words, a perfect number is a number that can be written as the sum of its divisors, excluding itself.

For example, the number 6 is a perfect number because its divisors are 1, 2, and 3, and 1+2+3 = 6.

8 is not a perfect number because it is not equal to the sum of its proper divisors. The divisors of 8 are 1, 2, 4, and 8, and 1+2+4 = 7, which is less than 8.

Therefore, 8 is not a perfect number. To this date, only 49 known perfect numbers have been found, they are all even numbers and the largest known perfect number is 2^(74,207,281) − 1, it has over 22 million digits.

The perimeter of the triangle formed by ABC is 26.56

A coordinate system is a method for determining how to position points or other geometrical objects on a manifold, such as Euclidean space, uniquely using one or more integers, or coordinates.In order to make it simple to identify the points, a cartesian plane divides the plane space into two dimensions.

Here,

The coordinate plane is another name for it. The horizontal x-axis and the vertical y-axis are the two axes of the coordinate plane. The origin is the place where these coordinate axes connect, and they split the plane into four quadrants (0, 0). Additionally, each point in the coordinate plane is denoted by the coordinates (x, y), where x represents the point's location in relation to the x-axis and y represents its position in relation to the y-axis.

The points on the plane are

A (1,-2) , B(8,-5) and C (5,5)

The length of AB is

=> (81)2+(-5+1)2 = √72 +42

= √65

The length of BC is

Answer:

So the solution is x = -0.57 and y = 30/7.

Step By Step Explanation:

To solve a system of linear equations, such as "x = 8 - 2y" and "3x + y = 6", we can use substitution or elimination method.

Using substitution method:

solve one equation for one variable

substitute the expression obtained in step 1 into the second equation

solve the equation obtained in step 2 to find the value of the variable that was solved for

substitute this value back into the first equation to find the value of the other variable.

x = 8 - 2y;

3x + y = 6;

solve for x in the first equation

x = 8 - 2y

substitute the value of x in the second equation

3(8-2y) + y = 6

solve the second equation obtained for y

24 - 6y + y = 6

25 - 6y = 6

-6y = -19

y = 19/6

substitute the value of y back in the first equation

x = 8 - 2(19/6) = 8 - (38/6) = 8 - (63/6) = 8 - (63/6) = 8 - 10.5 = -2.5

So the solution is x = -2.5 and y = 19/6

Alternatively, using elimination method:

Add or subtract one equation from the other to eliminate one of the variables.

Solve the resulting equation for the remaining variable.

Substitute this value into either of the original equations to find the value of the eliminated variable.

Multiply the first equation by -3

-3x = -24 + 6y;

Add the above equation to the second equation

-3x + y = 6

-24 + 6y + y = 6

-24 + 7y = 6

7y = 30

y = 30/7

substitute the value of y into the first equation

x = 8 - 2(30/7) = 8 - (60/7) = 8 - (60/7) = 8 - 8.57 = -0.57

So the solution is x = -0.57 and y = 30/7.

option A The inequity x ≥   3 indicates how many days it will take Rebecca to finish her orders.

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal symbol (). Different inequalities are used to contrast values, no matter how small or large. Many simple inequalities can be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

The equation of the tangent line to the circle through the point (-6,8) has equation = Y = 0.75x + 3.5

For circles that have a center at (0,0), the equation is  [tex]x^{2} + y^{2} = r^{2}[/tex]

[tex]x^{2} + y^{2} = 10^{2}[/tex]

[tex]x^{2} + y^{2}[/tex] = 100

We check if the point (-6,8) is a circle

[tex]x^{2} + y^{2}[/tex] = 100

[tex]-6^{2} + 8^{2}[/tex] = 36 + 64 = 100

So the point is exactly at circle line, as picture below

We solve the gradient of a normal line (n)

Mn = [tex]\frac{y2 - y1}{x2 - x1}[/tex] = [tex]\frac{8 - 0}{-6 - 0}[/tex]  = [tex]- \frac{8}{6}[/tex]

For perpendicular lines the gradient is

Mp = [tex]- \frac{1}{Mn}[/tex]  = [tex]\frac{- 1 }{-\frac{8}{6} }[/tex] = [tex]\frac{6}{8} = \frac{3}{4}[/tex]

The standard equation of a linear line is

Y =  mx + c

We need to find constant (c). We substitute x and y with point (-6,8)

So, x = -6 and y = 8

C = y - mx

C = 8 - ¾(-6) = 8 – [tex]\frac{18}{4}[/tex] = 3.5

With m = Mp =  [tex]\frac{3}{4}[/tex] and c = 3,5    

So, Y =  mx + c

      Y =     [tex]\frac{3}{4}[/tex] x + 3.5

      Y = 0.75x + 3.5

The product of (miles/hour) and (hours) is (miles), so only answers with units of distance are applicable. The numbers are ...

 f(3) = 2·3² +2 = 20 . . . . miles per hour

 g(3) = 3+2 = 5 . . . . hours

so (f·g)(3) = f(3)·g(3) = 20·5 = 100 . . . . miles

(f ⋅ g)(3) = 100, the distance in miles the bus traveled.

Step-by-step explanation:

Given functions:

[tex]\begin{cases}f(x)=2x^2+2\\g(x)=x+2\end{cases}[/tex]

To calculate the composite function (f ⋅ g)(3), multiply function f(3) by function g(3).

If function f(x) represents the rate of a bus travelling in miles per hour,

and function g(x) represents the time the bus travelled in hours:

[tex]\implies f(x) \cdot g(x)=\rm miles/hour \cdot hour=\dfrac{miles}{hour} \cdot hours=miles=distance[/tex]

Therefore, (f ⋅ g)(3) = 100 represents the distance in miles the bus traveled.

A Riemann sum is a method used to approximate the definite integral of a function. A definite integral is a measure of the area between a function and the x-axis over a certain interval. The Riemann sum formula is used to approximate this area by breaking up the interval into a number of subintervals (or "rectangles") and summing the areas of each rectangle. The formula for a Riemann sum is given by:

∑ f(x_i) * Δx

where f(x) is the function being integrated, x_i is the right endpoint of the i-th subinterval, Δx is the width of the subinterval, and the sum is taken over all the subintervals.

The Riemann sum formula is defined with a limit, as the number of subintervals approaches infinity and the width of subintervals approaches zero, the Riemann sum formula becomes the definite integral.

There are different ways to calculate Riemann sum, such as Left Riemann Sum, Right Riemann Sum, Midpoint Riemann Sum, and Trapezoidal Riemann Sum, each one of them has different ways to calculate x_i, thus leading to different results, but all of them approach the definite integral as the number of subinterval increases.
