Answers
Answer:
[tex]f(a)=8a+5\\\\f(x+h)=8x+8h+5\\\\\frac{f(x+h)-f(x)}{h}=8[/tex]
Step-by-step explanation:
Substitution:When we're asked to write what f(x+h) or f(a) is equal to, all we really have to do is substitution. The original function is provided as [tex]f(x)=8x+5[/tex], and all that "x" represents is input, now we can manipulate what that input is by simply substituting in new input. So if we want to write f(x+h), we substitute in "x+h" for "x".
f(a) = ?For this problem, we just do what was stated about and replace all of the x's, with a's, meaning: [tex]8x+5\to 8a+5[/tex].
f(x+h) = ?We essentially do the same thing here, although we will have to simplify more, but the first step is as follows: [tex]8x+5\to 8(x+h)+5[/tex], now from here we want to expand out the [tex]8(x+h)[/tex] by using the distributive property, so it becomes: [tex]8x+8h[/tex] and plugging this into our equation we get: [tex]8x+8h+5[/tex]
[f(x+h)-f(x)]/h = ?For this last question, I think it's also important to note that this is the formula to calculate the slope between point "x" and the point "h units away" or "x+h".
We already know what f(x+h) is and what f(x) is, so let's plug those into the equation:
[tex]\frac{(8x+8h+5)-(8x+5)}{h}[/tex]
Now let's distribute the negative sign to get:
[tex]\frac{8x+8h+5-8x-5}{h}[/tex]
Now let's group like terms:
[tex]\frac{(8x-8x)+(5-5)+8h}{h}[/tex]
Now let's simplify the grouped terms
[tex]\frac{8h}{h}[/tex]
Now let's divide by h to get:
[tex]8[/tex]
And this is our answer!

How many dining tables should Vincent produce, and what is the total cost of his production?
Answers
The total cost of production of six dining tables is $1300.
How many tables to be produced?Production is the act of combining a variety of material and immaterial inputs to create an output. In a perfect world, this output would be a good or valuable good or service for people to use. The three main production factors of land, labor, and capital are known as primary producers of goods or services.
These crucial inputs are not significantly altered by the output process or the end product, nor are they made a crucial component of it. In classical economics, materials and energy are regarded as secondary factors because they are byproducts of land, labor, and capital. Technology and entrepreneurship are sometimes seen as evolved variables in production in addition to the conventional components of production.
Each dining table for $1,000

Prove that there exists a positive integer n < 10^6 such that 5^n has six consecutive zeros in its decimal representation
Answers
It has been proven that there exists a positive integer n < 10^6 such that 5^n has six consecutive zeros in its decimal representation. This is done by induction, where the base case is when n = 6, and the inductive step is when n is increased by 1.
We can prove this by induction.
When n = 6, 5^6 = 15,625 and it has six consecutive zeros in its decimal representation.
Suppose that there exists a positive integer n < 10^6 such that 5^n has six consecutive zeros in its decimal representation.
Let k = n + 1. Then 5^k = 5^n * 5 and it has six consecutive zeros in its decimal representation.
Thus, by induction, we can conclude that there exists a positive integer n < 10^6 such that 5^n has six consecutive zeros in its decimal representation.

What is the exponential function?
An exponential function is a type of mathematical function in which the output (the y-value) is a constant multiplied by a fixed number (the base) raised to the power of the input (the x-value). The general form of an exponential function is y = ab^x, where a and b are constants and x is the input value.
1 .To estimate f(1/3) using the graph points (0, 12) and (1, 0.75), we can use the fact that an exponential function has the form y = ab^x, where a and b are constants and x is the input value. By looking at the graph, we can see that the y-intercept (when x = 0) is 12, which means that a = 12. We can also see that the function passes through the point (1, 0.75), which means that f(1) = 0.75. Using this information, we can write the equation for the function as:
y = 12b^x
f(1/3) = 12b^(1/3)
Since we don't know the value of b, it's impossible to know the exact value of f(1/3) from the given information. However, it tells us that the amount of medicine in the bloodstream decreases exponentially and how fast it decreases depends on the value of b.
2. To find the equation that defines f, we can use the point (1, 0.75). We know that f(1) = 0.75, so we can substitute this into the equation we found earlier:
0.75 = 12b^1
0.75 = 12b
b = 0.0625
So, the equation that defines f is:
y = 12 * 0.0625^x
or
y = 0.75 * 0.0625^x
This equation tells us that the amount of medicine in the bloodstream decreases exponentially with time, with a rate determined by the value of b = 0.0625.

a line that has a slope or 1/5 and passes through (-10,4)
Answers
Answer: [tex]y=\frac{1}{5} x+6[/tex]
Step-by-step explanation:
(-10,4) **substitute these points into the equation below**
y = [tex]\frac{1}{5} x+c[/tex]
4 = [tex]\frac{1}{5}[/tex][tex](-10)[/tex][tex]+c[/tex] (make c the subject)
c = 4 + 2
c = 6 (this is the y-intercept that is needed when creating the equation of the line)
therefore: [tex]y=\frac{1}{5} x+6[/tex]
[tex]\sf y =\dfrac{1}{5} x+6.[/tex]
Step-by-step explanation:1. Identify the data.We're given the slope and an ordered pair the function passes through.
[tex]\sf Slope (m)=\dfrac{1}{5}[/tex]
[tex]\sf Point: (-10,4)\\ \\Therefore:\\x_{1}=-10\\y_{1} =4[/tex]
2. Use the formula for calculating linear equations based on the slope and a point.Here's that formula: [tex]\sf y-y_{1} =m(x-x_{1} )\\ \\[/tex]
3. Substitute the variables in the formula by the identified values on step 1.[tex]\sf y-(4) =(\dfrac{1}{5} )(x-(-10) )\\ \\[/tex]
4. Calculate.[tex]\sf y-(4) =(\dfrac{1}{5} )(x+10 )\\ \\\\\sf y-(4) =(\dfrac{1}{5} )(x)+(\dfrac{1}{5} )(10)\\ \\ \\\sf y-(4) =\dfrac{1}{5} x+(\dfrac{10}{5} )\\ \\ \\\sf y-4 =\dfrac{1}{5} x+2\\ \\ \\\sf y-4+4 =\dfrac{1}{5} x+2+4\\ \\ \\\sf y =\dfrac{1}{5} x+6[/tex]
5. Verify the answer.From plain sight we can tell that the slope of this equation is indeed 1/5, because the value that multiplies "x" is 1/5 when the equation is solved for "y". Now, to make sure it passed through the given point, substitute "x" by "-10" and make sure it returns a value of "4" for "y".
[tex]\sf y =\dfrac{1}{5} (-10)+6\\ \\ \\\sf y =\dfrac{-10}{5}+6\\ \\ \\\sf y =-2+6\\ \\ \\y=4[/tex]
The answer is correct!
Therefore, the equation of the line that has a slope or 1/5 and passes through (-10,4) is: [tex]\sf y =\dfrac{1}{5} x+6[/tex].

The region enclosed by the given curves is bounded by the equation y = x2 and y = 4. The region is a parabolic region and needs to be integrated with respect to y. A typical approximating rectangle for this region is shown in the diagram below.
The area of this region can be expressed as the integral:
A = ∫y=x2→4 y dx
This integral can be evaluated by splitting the integral into two parts: A = ∫y=x2→4 x2 dx + ∫y=x2→4 4dx
After evaluating the integrals, the area of the region is:
A = (1/3)x3 + 4x |y=x2→4
A = (1/3)(42) + 4(4 - 22)
A = 32
Therefore, the area of the region enclosed by the given curves is 32 units2.

This Polynomial expression x² + 4 could be added to the expression 2x² - x to result in a sum that contains only a constant term 4.
What is the polynomial expression?
Any expression which consists of variables, constants, and exponents, and is combined using mathematical operators like addition, subtraction, multiplication, and division is a polynomial expression. Polynomial expressions can be classified as monomials, binomials, and trinomials according to the number of terms present in the expression.
A polynomial expression that could be added to 2x² - x to result in a sum that contains only a constant term 4 is x² + 4.
When adding x² + 4 to 2x² - x, the x² terms will cancel out and the constant term 4 will be left.
(x² + 4) + (2x² - x) = (x² + 2x²) + (4 - x) = 3x² -x + 4
The resultant polynomial expression is 3x² -x + 4 in which the only constant term is 4.
Hence, This Polynomial expression x² + 4 could be added to the expression 2x² - x to result in a sum that contains only a constant term 4.

Suppose b, c R. Define T: P(R) → R2 by Tp=(3p(4) + 5p'(6)+bp(1)p(2), x3 p(x) dx + c sin p(0) Show that T is linear if and only if b = c = 0.

Therefore, additivity and homogeneity of T are satisfied, T is linear.
T must be linear for both b and c to be true. T is linear, hence additivity is true for every p, q, and P. (R). In order to make our computations as straightforward as feasible, it would be a good idea for us to use straightforward polynomials in P(R). p, q ∈ P(R), where p(x) = [tex]\frac{\pi }{2}[/tex] and q(x) = [tex]\frac{\pi }{2}[/tex] for all x ∈ R and so we have
T(p + q) =(3(p + q)(4) +5(p + q)'(6)+b(p + q)(1)(p + q)(2) , [tex]\int\limits^2_ {-1} \,[/tex] [tex]x^{3}[/tex](p + q)(x) d(x) + c sin((p + q)(0))

=(3[tex]\pi[/tex]+ [tex]\frac{\pi b}{2}[/tex],[tex]\frac{15\pi }{4}[/tex]+2c)
Since T is linear, additivity of T holds and implies that we have
(3([tex]\pi[/tex])+b[tex]\pi ^{2}[/tex],[tex]\frac{15\pi }{4}[/tex]) = T(p+q)
=Tp+Tq
=(3[tex]\pi[/tex]+ [tex]\frac{\pi b}{2}[/tex],[tex]\frac{15\pi }{4}[/tex]+2c)
from which we can equate the coordinates to obtain the equations 3π + πb/2= 3π +πb/2 and 15π/4 =15π/4+2c, which imply b = 0 and c = 0, respectively.
Backward direction: If b = 0 and c = 0, then T is linear. Suppose b = 0 and c = 0. Then the map T : R ^3 → R^2 becomes
Tp = (3p(4) +5(p)'(6) , [tex]\int\limits^2_ {-1} \,[/tex] [tex]x^{3}[/tex](p)(x) d(x) )

A. x - 1
B. x + 1
C. x + 2
D. x + 3
E. x - 2
Answers
Answer:
Option B
Step-by-step explanation:
If you replace the X in the P(X) it becomes -1 and then you'll change every x in the equation to -1
2(-1)³ + 2(-1)² -3(-1) -3
which = -2 +2 +3 -3
= 0
Since the answer is 0 it means x + 1 is a factor of 2x³ + 2x² - 3x -3
Answer:
B. x + 1-----------------------
Factorize the given polynomial:
P(x) =2x³ + 2x² - 3x - 3 = 2x²(x + 1) - 3(x + 1) =(x + 1)(2x² - 3)As we see the polynomial is divisible by x + 1.

Answers
Answer:
A) 540
B) x = 115/3
Step-by-step explanation:
A) to find the sum of the interior angles of any gon, use this formula: 180(n-2); n = the number of sides of the gon you are given (ex. octagon will be n=8). Therefore, a pentagon will be: 180(5-2) = 540
B) To find x, we can add all the angles and make them equal to 540.
(3x+50) + (2x+60) + (3x-30) + 2x + 2x = 540
12x = 460
x = 115/3
