Identify the correct command to find the derivative ofywith respect toxof the following equation:y=4x∧4−3x∧2+6x+14dydx=polyder([4,0,−3,6],14)dydx=polyder([4,0,−3,6,14])dydx=polyder(4,0,−3,6,14)dydx=polyder([4,−3,6],14) Explanation: When taking the derivative of a polynomial, the coefficients of the polynomial must be arranged in decending powers, being careful to specify zero for missing terms. The constant (i.e.,xto the zero power) is included in the array of coefficients.
The derivative of the given polynomial equation is 16x³ - 6x + 6.
We are given an equation. The equation represents a polynomial in one variable. The degree of the polynomial is four; hence, it is called biquadratic. We need to find the derivative of the given polynomial. The derivative of a function of a real variable in mathematics describes the sensitivity of the function value to a change in its argument. Calculus relies heavily on derivatives.
The equation is given below.
y = 4x^4 - 3x² + 6x + 14
dy/dx = (d/dx)(4x^4 - 3x² + 6x + 14)
dy/dx = (d/dx)(4x^4) - (d/dx)(3x²) + (d/dx)(6x) + (d/dx)(14)
dy/dx = [4*4x^(4 - 1)] - [3*2x^(2 - 1)] + [6*1x^(1 - 0)] + [14*0x^(0 - 1)]
dy/dx = 16x³ - 6x + 6
Hence, the derivative of the given polynomial equation is 16x³ - 6x + 6.

The value of x is 32.5°(degree) when isosceles triangle has a base angle of (4x-3)degrees and non base angle is 54 degrees.
How to calculate the value of x?We know that an isosceles triangles is composed of a vertex angle and two base angles. The base angles are congruent to each other. We also know that the sum of a triangle's angles is 180°(degrees).
According to given data,
⇒ 180 - {(4x-3)+54}= 0
⇒180 - 4x + 3 - 54 = 0
⇒130 = 4x
∴ x = 32.5°(degree).
That means that each base angle is 32.5°(degree).

Referring to the Fig. in Question #1, find the area of the regular polygon
shown. [Note: do not approximate the value of any radicals; thus, if you
obtain, for example, 45 times the square root of 3, simply type 45SQR(3)
as your final answer.]
Answer:
Perimeter = 18√3 = 18SQR(3)
Area = 27√3 = 27SQR(3)
Step-by-step explanation:
The sides of a regular polygon are congruent.
Therefore, as the triangle is a regular polygon, it is an equilateral triangle since its sides (and interior angles) are congruent.
The interior angles of a triangle sum to 180°. Therefore, each interior angle of the equilateral triangle is 60°.
Therefore, the right triangle formed inside the equilateral triangle by the perpendicular bisectors is a 30-60-90 triangle with hypotenuse of 6 units.
The ratio of the side lengths of a 30-60-90 triangle is b : b√3 : 2b, where:
b = shortest side opposite the 30° angle.b√3 = side opposite the 60° angle.2b = longest side (hypotenuse) is opposite the right angle.As the hypotenuse of the 30-60-90 right triangle is 6 units:
[tex]2b = 6 \implies b=3[/tex]
Therefore, the length of the longest leg of the right triangle is 3√3.
As this is half the length of one side of the equilateral triangle:
[tex]\implies \sf Perimeter = 6 \times 3 \sqrt{3}=18\sqrt{3}\; units[/tex]
Heron's Formula allows us to find the area of a triangle in terms of its side lengths.
Heron's Formula
[tex]\sf Area = \sqrt{s(s-a)(s-b)(s-c)}[/tex]
where:
a, b and c are the side lengths of the triangle.s is half the perimeter.Given:
Each side length = 6√3 unitsHalf perimeter = 9√3 unitsSubstitute these values into the Heron's formula to calculate the area of the equilateral triangle:
[tex]\begin{aligned}\implies \sf Area &= \sf \sqrt{9\sqrt{3}(9\sqrt{3}-6\sqrt{3})^3}\\ &= \sf \sqrt{9\sqrt{3}(3\sqrt{3})^3}\\ &= \sf \sqrt{9\sqrt{3}(81\sqrt{3})}\\&=\sf \sqrt{2187}\\&=\sf \sqrt{729 \cdot 3}\\&=\sf \sqrt{729}\sqrt{3}\\&=\sf 27\sqrt{3} \;\;units^2\end{aligned}[/tex]

a rectangle with a diagonal of length xx is twice as long as it is wide. what is the area of the rectangle?
A rectangle with a diagonal of length x is twice as long as it is wide, the area of the rectangle is (B) 2x²/5..
How to find the area of the rectangle?Given that we have a rectangle with a diagonal of length x is twice as long as it is wide.
Let
L = length of rectangle,
W = width of rectangle and
D = length of diagonal = x
Given that the length of diagonal, x is twice as long as it is wide, we have that
L = 2W
Also, since it is rectangle, we have that
D² = L² + W²
D² = (2W)² + W²
D² = 4W² + W²
x² = 5W²
W² = x²/5
W = x/√5
W = x√5/5
since the length of the rectangle, L = 2W, we have that
L = 2W
= 2x√5/5
The area of the rectangle
The area of the rectangle is given by A = LW where
L = length of rectangle and
W = width of rectangle
So, A = LW
= 2x√5/5 × x√5/5
= 2x² × 5/25
= 2x²/5
So, the area of the rectangle is (B) 2x²/5

At 61°F, a certain insect chirps at a rate of 99 times per minute, and at 64°F, they chirp 117 times per minute. Write an equation in slope-intercept form that represents the situation.
An equation in slope-intercept form that represents the situation is C(x) = -267 + 6x.
What is the equation in slope intercept form?A linear equation is an equation that has a single variable that is raised to the power of one. When shown on a graph, a linear equation is a straight line that can slope either upward or downward.
The general form of a linear equation is
y = mx + b
Where:
b = intercept y = dependent variable x = independent variable m = slopeSlope = change in the chirps / change in the temperature
Slope = (117 - 99) / (64 - 61)
Slope = 18 / 3
Slope = 6
99 = a + 6x
99 = a + 6(61)
99 = a + 366
a = 99 - 366
a = -267
C(x) = -267 + 6x

The sequence that can be defined by the recursive formula is (c) 4, 2.75, 1.5...
How to determine the elements of the recursive definition of f?The function definition is given as
f(1) = 4
f(n + 1) = f(n) - 1.25 for n ≥ 1
Set n = 1
So, we have the following representation
f(1 + 1) = f(1) - 1.25
This gives
f(2) = f(1) - 1.25
So, we have
f(2) = 4 - 1.25 = 2.75
Set n = 2
So, we have the following representation
f(2 + 1) = f(2) - 1.25
This gives
f(3) = f(2) - 1.25
So, we have
f(3) = 2.75 - 1.25 = 1.5
So, we have
4, 2.75, 1.5...
The sequence that matches 2.75, 1.5... in the options is (c) 4, 2.75, 1.5...
