f(6) = - 10 and g(- 4) = 125
Step-by-step explanation:
substitute x = 6 into f(x) , that is
f(6) = - 2(6) + 2 = - 12 + 2 = - 10
substitute x = - 4 into g(x) , that is
g(- 4) = - 2(- 4)³ - 3 = - 2(- 64) - 3 = 128 - 3 = 125

Which describes the graph of y= -(x - 3)² + 2?
Answers
which means the graph is on quadrate 2 or 3.
Straight Line :
A straight line is an infinite-length line that does not have any curves on it. A straight line can be formed between two points also but both ends extend to infinity. A straight line is a figure formed when two points A (x1, y1) and B (x2, y2) are connected with the shortest distance between them, and the line ends are extended to infinity.
In the image shown below, a straight line between two points A and B is shown. A straight line AB is represented by: Vector AB
The lines are drawn in a slanting position or form some angle other than 0o, 90o, 180o, 270o, 360o with horizontal or vertical lines are called oblique or slanting lines.
y= -(x - 3)² + 2.
y= - (x2+9-6x)+2
y= -x2-9+6x+2
y= -x2-7+6x
y= -x2+6x-7
-y = x2+7x-x-7
-y= x(x+7)-1(x+7)
-y= (x+7)(x-1)
which means the graph is on quadrate 2 or 3.
straight line graph of y = -(x - 3)² + 2.4

Answers
The differences between the trapezoidal rule and simpson's rule is -
The trapezoidal rule and Simpson's method, the latter a set of formulas of varying complexity, are both Newton-Cotes formulas, that are used to examine and model complex curves.
What is trapezoidal rule?The trapezoidal rule is just an integration rule that divides a curve into small trapezoids to calculate the area under it. A area under the curve is calculated by adding the areas of all the small trapezoids.
Follow the steps below to use the trapezoidal rule to determine the area under given curve, y = f. (x).
Step 1: Write down the total number of sub-intervals, "n," as well as the intervals "a" and "b."Step 2: Use the formula to determine the width of the sub-interval, h (or) x = (b - a)/n.Step 3: Use the obtained values to calculate this same approximate area of a given curve, ba f(x)dx Tn = (x/2) [f(x0) + 2 f(x1) + 2 f(x2) +....+ 2 f(n-1) + f(n)], where xi = a + ixWhat is Simpson's method?Simpson's rule is used to approximate the area beneath the graph of the function f to determine the value of the a definite integral (such that, of the form b∫ₐ f(x) dx.
Simpson's 1/3 rule provides a more precise approximation. Here are the steps for using Simpson's rule to approximate the integral ba f(x) dx.
Step 1: Figure out the values of 'a' & 'b' from interval [a, b], as well as the value of 'n,' which represents the number of subintervals.Step 2: Determine the width of every subinterval using the formula h = (b - a)/n.Step 3: Using the interval width 'h,' divide this same interval [a, b] [x₀, x₁], [x₁, x₂], [x₂, x₃], ..., [xn-2, xn-1], [xn-1, xn] into 'n' subintervals.Step 4: In Simpson's rule formula, substitute all of these values and simplify. b∫ₐ f(x) dx ≈ (h/3) [f(x0)+4 f(x1)+2 f(x2)+ ... +2 f(xn-2)+4 f(xn-1)+f(xn)].Thus, sometimes we cannot solve an integral using any integration technique, and other times we don't have a particular function to integrate. Simpson's rule aids in approximating the significance of the definite integral in such cases.

First cross multiply
E/e = (R + r)/r
e(R + r) = rE
Now, divide both sides of the equation by (R + r)
That is,
e(R + r)/ (R + r) = rE/ (R + r)

The given algebraic expression 8x ia a one degree polynomial forming the straight line.
What is defined as the polynomials?Polynomials are algebraic expressions with indeterminates and constants in them.
A polynomial is a form of algebraic expression wherein all variable exponents are whole numbers. Variable exponents in any polynomial must be non-negative integers.The degree of a polynomial is the highest as well as greatest exponent of a variable in a polynomial. Utilising Descartes' Rule of Signs, the degree is used to estimate the optimum number of solutions to a polynomial equation.For the given algebraic expression 8x;
As, the highest exponent of the variable part 'x' is 1 that is why the degree of the polynomial is one.
This implies that for every value of x there is a single value of value of functions.
This will form the straight line when graph is plotted for them.
Thus, the given algebraic expression 8x is called the one degree polynomial.

The length of the given rectangle is 4ft more than twice the width. The perimeter of the particular rectangle is 26ft. Length and width of the rectangle is [tex]10ft[/tex] and [tex]3ft[/tex]
As per the question statement, The length of the given rectangle is 4ft more than twice the width. The perimeter of the particular rectangle is 26ft.
We are supposed to find out dimensions of the rectangle.
Let length of the rectangle = l
Width of the rectangle = w
[tex]l = 4 + 2w[/tex]
Perimeter of rectangle = [tex]2(l+w)[/tex]
Above mentioned are the given conditions in the linear equation form.
Perimeter of rectangle = [tex]2(l+w)[/tex] = 26 ft.
[tex]l+w = \frac{26}{2}[/tex]
[tex]l+w =13[/tex]
substituting [tex]l = 4 + 2w[/tex]
[tex]4+2w+w=13\\4+3w=13\\3w=13-4=9\\w=\frac{9}{3}[/tex]
[tex]w=3[/tex]
Hence width is 3ft.
Now length, [tex]l = 4 + 2w[/tex]
[tex]l=4+2*3\\l=4+6\\l=10[/tex]
