Answer:

[tex]\displaystyle y=-\frac{3}{8}x+2[/tex]

Step-by-step explanation:

Perpendicular lines have opposite reciprocal slopes. So, we must first determine our slope of the original equation by converting to slope-intercept form:

[tex]-8x+3y=-6\\3y=8x-6\\y=\frac{8}{3}x-2[/tex]

Hence, because the slope of the original line is 8/3, then the slope of the perpendicular line is -3/8. We are not done, however, as we need to account for the point that the perpendicular line passes through by solving for the new y-intercept:

[tex]y=-\frac{3}{8}x+b\\ \\8=-\frac{3}{8}(-16)+b\\\\8=6+b\\\\2=b[/tex]

Thus, the perpendicular line equation is [tex]y=-\frac{3}{8}x+2[/tex]. See below for a graph.

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

[tex]-8x+3y=-6\implies 3y=8x-6\implies y=\cfrac{8x-6}{3} \\\\\\ y=\stackrel{\stackrel{m}{\downarrow }}{\cfrac{8}{3}}x-2\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill[/tex]

[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{ \cfrac{8}{3}} ~\hfill \stackrel{reciprocal}{\cfrac{3}{8}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{3}{8} }}[/tex]

so we're really looking for the equation of a line whose slope is -3/8 and it passes through (-16 , 8)

[tex](\stackrel{x_1}{-16}~,~\stackrel{y_1}{8})\hspace{10em} \stackrel{slope}{m} ~=~ - \cfrac{3}{8} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{8}=\stackrel{m}{- \cfrac{3}{8}}(x-\stackrel{x_1}{(-16)}) \implies y -8= -\cfrac{3}{8} (x +16) \\\\\\ y-8=-\cfrac{3}{8}x-6\implies {\Large \begin{array}{llll} y=-\cfrac{3}{8}x+2 \end{array}}[/tex]

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 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°

So, tha angle is 320°

The fraction of their money remains for other expenses each month is 5/12.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given:

Williams spend 1/3 of their total monthly income for rent and 1/4 for food.

The fraction of their money remains for other expenses each month,

The slope of the line represented by the graph of a linear function is  -5/2

The general equation of a straight line is -

y = mx + c

where -

m → slope of line

c → y - intercept of line

here, we have,

Given in a question a linear function that decreases from left to right passing through the coordinates A(0,3) and B(2, -2).

A linear function is a function of general equation → y = ax + b which is same as y = mx + c.

So, it represents a straight line.

The line passes through the points A (0,3) and  B (2, -2).

The Slope of the given line can be calculated using the following formula -

m = (y[2] - y[1]) / (x[2] - x[1])

m = (- 2 - 3) / (2 - 0)

m = -5/2

Therefore, the slope of the line represented by the graph of a linear function is  -5/2.

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.

The lateral surface area painted black = 30% of 60π.

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

The length of the remaining sides is a = 57.50 and b = 61.93.

The law of sines specifies how many sides there are in a triangle and how their individual sine angles are equal. The sine law, sine rule, and sine formula are additional names for the sine law.

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

sinB/b = sinC/c

The politician experience 16% of actual change and 47% relative change in his support.

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 relative change of politician's support is:

Relative change = Ending% - Initial %

                                    Initial %

Relative change = 50% - 34%

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.
