The required solution of the given differentiation is given as y'(2) = 135/16. Option A is correct.

The method of determining the derivative of an implicit function is by differentiating each term separately, expressing the derivative of the dependent variable as a symbol, and solving the resulting expression for the symbol.

here,
y = [x - 1/x]³
y' = 3[x - 1/x]² × [1 + 1/x²]

put x = 2
y'(2) = 3 [2 - 1/2]² × [1 + 1/4]
y'(2) = 3[3/2]²[5/4]
y'(2) = 27/4 × 5/4
y'(2) = 135/16

Thus, the required solution of the given differentiation is given as y'(2) = 135/16.

The exponential grows at the same rate as the quadratic in the interval

0 ≤ x ≤ 1.

The average Rate of Change function is defined as the average rate at which one quantity is changing with respect to something else changing. In simple terms, an average rate of change function is a process that calculates the amount of change in one item divided by the corresponding amount of change in another.

The average rate of change of a function A = [tex](f(a) - f(b))/(b-a)[/tex]

Given an exponential function, say f(x), such that f(0) = 1 and f(1) = 2.

A quadratic function, say g(x), such that g(0) = 0 and g(1) = 1.

The rate of change of a function f(x) over an interval a ≤ x ≤ b is given by

[tex](f(a) - f(b))/(b-a)[/tex].

Thus, the rate of change (growth rate) of the exponential function, f(x) over the interval 0 ≤ x ≤ 1 is given by

 = (2-1)/1 = 1

Similarly, the rate of change (growth rate) of the quadratic function, g(x) over the interval 0 ≤ x ≤ 1 is given by

=(1 - 0)/1  = 1

Therefore, the exponential grows at the same rate as the quadratic in the interval 0 ≤ x ≤ 1.

It usually consists of variables, coefficients, and constants, connected by operations such as addition, subtraction, multiplication, and division. Equations are used to model relationships between different quantities and to solve problems in various fields such as physics, engineering, and economics. For example, the equation y = mx + b represents a straight line in two-dimensional space, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept.

The line 2x + 3y = 5 contains AB, so AB lies on the line 2x + 3y = 5. To dilate triangle ABC to A'B'C, the center of dilation is a fixed point and the scale factor is a constant. Since AB lies on the line 2x + 3y = 5, the line containing A'B' after dilation must be parallel to the line 2x + 3y = 5, so the correct answer is (a) 3x + 2y = 10.

The angle of least positive measure coterminal with -40 degrees is 320°

Coterminal angles are angles that share the same initial side and the same terminal side.

Since we have our initial angle as -40 degrees.

Let x be the angle of least positive measure coterminal with -40 degrees

We know that to get coterminal angles, we add or subtract 360° to the angle.

So, for a positive coterminal angle, we add 360° to it.

So, x = (-40°) + 360°

Which gives

x = -40° + 360°

x = 320°

The total surface area painted black = 56.5 square feet to the nearest tenth.

A cone is a three-dimensional geometric form with a flat base and a smooth, tapering apex or vertex. A cone is made up of a collection of line segments, half-lines, or lines that link the base's points to the apex, which is a common point on a plane that does not include the base.

Given that, three large cones hang from the ceiling in an office building in front of a bank of windows.

The height of each cone is 12 feet, and the circumference of the base of each cone is 8π feet.

The base and 40% of the lateral surface of each cone is painted red, and the rest of each cone is painted black.

Circumference of the base of the cone = 8π feet.

2πr = 8π

πr = 4π

The surface area of the cone = πr x slant height

Slant height = [tex]\sqrt{radius^2+height^2}[/tex]

= √12²+4² = 12.6 ft

The surface area of the cone = 12.6 x 4π

The surface area of the cone = 60π.

Parallel lines are any two or more lines that all lie in the same plane and never cross one another. They are equally spaced apart and have the same incline.

Numerous pairs of angles are created whenever any two parallel lines are intersected by a third line known as a transversal. The other angles are supplementary while some are congruent (equal).

Angles on a straight line sum up 180°

Let us take the line t as our straight line

(7x – 1)° + (9x + 5)° = 180°

(7x + 9x + 5 – 1) = 180

16x + 4 = 180

(-5, -3), in slope-intercept form, is parallel to the equation -3x - 7y = 10.

Therefore, we must first determine this's slope.

-3x - 7y = 10

To both sides, add three.

-7y = 3x + 10

Add -7 to both sides.

y = -3/7x - 10/7

Our slope is thus -3/7.

The slopes always remain the same when searching for a line that is parallel to something.

Remember that y = mx+b is the slope-intercept form as well.

Where b is the y-intercept and m is the slope.

Our y-intercept is -3 since the coordinates (-5,-3) are available.

The slope here is -3/7.

Put those numbers into the slope-intercept form equation, then, to solve.

The equation of the line parallel to the given line is y = -3x/7 + 47/7

The equation of the perpendicular will be  y = 7x/3 -13/3

The formula for a straight line is y=mx+c where c is the height at which the line intersects the y-axis, often known as the y-intercept, and m is the gradient.

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.

The slope of a line that is perpendicular to another line is equal to the negative reciprocal of that line's slope. The slope of the original line's perpendicular line is -2, which is the original line's negative reciprocal.

The equation of the line is 3x + 7y = 8

The slope of the line is = -3/7

so the equation of the line parallel to the given line is y = -3x/7 + c

the point given as (4,5)

The line is 5 = -3*4/7 + c

or, c = 5 + 12/7 = 47/7

the equation of the line parallel to the given line is y = -3x/7 + 47/7

The slope of the line perpendicular to the given line is 7/3

So, the equation of the line is y = 7x/3 + c

The intercept is 5 = 7*4/3 + c

Actual change refers to the simple difference between the ending and initial condition. In this case, actual change is the gap of the politician's support increase. The actual change of the politician's support is:

Actual change = Ending% - Initial %

Actual change = 50% - 34%

Actual change = 16%

Relative change is the percentage change between ending and initial condition based on the perspective of the initial condition. Relative change measures the gap between the ending and initial conditions compared to the initial condition. Relative change can be calculated by dividing the gap of 2 conditions with the initial condition.

The side or unknown angle of an oblique triangle is found using the law of sine. Any triangle that is not a right triangle is referred to as an oblique triangle.

Given a triangle ABC, and ∠B = 90°

∠A = 68.2° and c = 23.0

so ∠C = 90 - ∠A

∠C = 90 - 68.2

∠C = 21.8°

according to the law of sines,

sinA/a = sinB/b = sinC/c

for a,

sinA/a = sinC/c

substitute the values

sin(68.2)/a = sin(21.8)/c

a = 23(sin68.2)/(sin21.8)

a = 57.50
