The required  mark-up percentage of the manager is 60%.

The gross profit of a unit, which is its sales price less its cost to produce or acquire for resale, is divided by the unit's cost to determine the markup %. The markup percentage, which is computed as (12 - 8) / 8, is 50% for an item that costs the business $8 to produce but is priced at $12.

We have,

Cost price of the Unit = $350

Selling price of the unit = $560

Then,

Mark-up percentage = ($560 - $350)/$350 × 100

Mark-up percentage = $210/$350 × 100

Mark-up percentage = 0.6 × 100

Mark-up percentage = 60%

The slope of the line that passes through the points (9,8) and (2,3) is 5/7.

The slope of a line in a graph is a measure of its steepness or slant. It is defined as the ratio of the vertical change (rise) to the horizontal change (run) between any two points on the line. In mathematical terms, the slope of a line can be represented as the difference in the y-coordinates of two points on the line divided by the difference in the x-coordinates of the same two points.

The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula:

slope = (y2 - y1) / (x2 - x1)

Plugging in the given points, we get:

slope = (3 - 8) / (2 - 9) = -5 / -7 = 5/7

So, the slope of the line that passes through the points (9,8) and (2,3) is 5/7.

Therefore , the solution of the given problem of equation comes out to be cost of one pair of pants is $40.

The similar symbol (=) is used in mathematical equations to variables denote equality between two propositions. Mathematical formulae, which are abstractions of reality, are used to demonstrate how different numerical factors can be compared. For instance, the equal sign splits the integer 12 or perhaps the equation y + 6 = 12 to two separate halves. One can compute how so many characters each side of the a character has. Contradictory meanings are common in symbols.

Here,

Given :

Mathew bought 5 shirts and 2 pairs of pairs is $165.

Toby bought 3 shirts and 5 pairs of pants for $251.

x is the shirt of price ,

y is the pants of price .

Thus,

=> 5x + 2y = 165

=> 3x + 5y = 251

So,

=> x = 165 -2y/5

=> 3(165 - 2y/5) + 5y = 251

=> 3(165 - 2y /5) + 5y = 251

=>  495 - 6y  + 25y = 251 *5

=>  495 + 19y = 1255

=> 19y = 1255 - 495

=> 19 y =  760

=> y =760/19

=> y = 40

and

=> x = 165 - 2*40 /5

=> x = 165-80/5

=> x = 85/5

=> x =17

Thus , cost of one pair of pants is $40.

for the first point, the first statement is true since both lines intersect at (4,5)

for the second point, this is also true because since (4,5) is on both functions, x=4 and y=5 will be a solution for both

for the third point, this is also true since the point of intersection is (4,5), this is the solution for the system

for the fourth point, this is untrue. since we don't know what f and g are and the only solution to the system is (4,5), what works for f may not necessarily work for g. so 4/d is the answer.

A triangle is a polygon with three sides and three vertices. The triangle's total number of angles comes to 180°. The distances between the formed the sight-lines are;

RB = 210 feet

OC = 275 feet

The distance between the point close to the river and the next point further from the river = is 115 feet

In triangles ΔPRB and ΔPOC,

we have;

∠PRE = ∠POC = 90°

Given;

∠PER ≅ ∠PCO

By the corresponding angle formed between two parallel lines and a common transversal.

Using angle-angle similarity theorem;

ΔPRE is similar to ΔPOC Which gives;

PR / PO = RE / OC

Let x represent the distance across the river,

we have;

PR = x

PO = 115 + x

Which gives;

x / (115+x) = 210 / 275

275x = 210 × (115 + x)

275x = 24150 + 210x

275x - 210x = 24150

65x = 24150

x = 371. 54

The value of the trigonometric relation tan θ = 0.25819889

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin (-θ) = -sin (θ)

csc (-θ) = -csc (θ)

cos (-θ) = cos (θ)

sec (-θ) = sec (θ)

tan (-θ) = -tan (θ)

cot (-θ) = -cot (θ)

In the first quadrant, sin, cos and tan are all positive.

In the second quadrant going anti-clockwise, only sin is positive.

In the third quadrant going anti-clockwise, only tan is positive.

In the fourth quadrant going anti-clockwise, only cos is positive

Given data ,

Let the angle be represented as θ

Now , the measure of sin θ = - ( 1/4 )

So , the value of θ lies in the 3rd quadrant

Taking inverse on both sides of the equation , we get

θ = sin⁻¹ ( - ( 1/4 ) )

θ = 194.47751218° + 2πn

Now , In the third quadrant going anti-clockwise, only tan is positive.

So , tan θ = tan ( 194.47751218 )

On simplifying the equation , we get

tan ( 194.47751218 ) = 0.25819889

Hence , the value of tan ( 194.47751218 ) is 0.25819889

Step-by-step explanation:

it says it in the headline : the cube root function.

1.

it goes through (0, 0) and (1, 1) and (-1, -1).

so,

f(x) = cubic root(x)

domain = (-infinity, +infinity)

range = (-infinity, +infinity)

x-intercept = 0

y-intercept = 0

2.

the function is y = cubic root(x + 2)

compared to

y = cubic root(x)

the domain is x >= -2

wrong !

this is not a square root. for the square root that domain would be correct (there are no real number square roots for negative values). but cubic roots are possible also for negative values. this function has the same domain and range as the basic y = cubic root(x) : (-infinity, +infinity).

the function is a vertical translation of g(x) = cubic root(x).

wrong !

vertical means up/down.

but it is a horizontal (left/right) translation of that g(x). by 2 units to the left, actually.

3.

for 1 <= x <= 4 we have already the average rate of change :

about 0.197

for 4 <= x <= 7 we get

(f(7) - f(4))/(7 - 4) ≈ (1.91 - 1.59)/3 ≈ 0.109

so, the interval [1, 4] has a greater average of change.

which is also clear when looking at the graph : the function increases stronger for the lower x-values than for the larger x-values.
