Step-by-step explanation:

Answer:

p = - 2x + 54

Step-by-step explanation:

The price-demand linear equation is

p = mx + b

which is the equation of a straight line in slope-intercept form

The parameters here are m = slope and b = y-intercept in line equation terms

x is the number of shirts sold and p is the price

Using values given, we can generate two equations which can solve for the parameters of the linear equation

To sell 10 shirts, the price has to be $34
==> 34 = m x 10 + b = 10m + b

Switch sides to get 10m + b = 34     (1)

To sell 20 shirts, the price has to be $14
==> 14 = 20m + b  
Switch sides to get 20m + b = 14   (2)

Subtract (2) from (1) to eliminate the term b

(1) - (2)
==> 10m+b - (20m+b) = 34 - 14    

==> 10m + b - 20m - b = 20
==> 10m - 20m = 20
==> - 10m = 20

==> m = 20/(- 10) = - 2.4  

==> m = - 2.0
This term is also referred to as the elasticity of demand ie how much demand changes with respect to price change. It is negative here because as you increase the price, the demand decreases

Now that we have value for m all we have to do is plug it into one of the equations (1) or (2) and solve for b

Using equation (2),
20(- 2) + b = 14

==> - 40 + b = 14
==> 0 + b = 14 + 54(Add 48 on both sides)

==> b = 54

So the price-demand equation is

Answer:

45°

Step-by-step explanation:

A parallelogram is a polygon with 4 sides and 4 angles (that is a quadrilateral).

For a parallelogram ABCD, Opposite sides and opposite angles are equal (i.e. BC = AD and ∠A = ∠C).

Consecutive angles are supplementary that is ∠A + ∠B = 180°.

The diagonals of a parallelogram bisect each other also separating the parallelogram into two congruent triangles.

In parallelogram HIJK, ∠H and ∠J are opposite angles. hence:

∠H = ∠J (opposite angles of a parallelogram are equal)

∠J = 45°

Answer: indirect characterization

Step-by-step explanation:

Indirect characterization is a method of indicating what a character is like by revealing their personality through descriptions of their actions, speech, appearance, and interactions with other characters.

Based on the calculations using the midpoint rule, the value of point S is equal to (10, 12).

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

In order to determine the midpoint of a line segment with two (2) endpoints, we would add each point together and divide by two (2).

Midpoint on x-coordinate is given by:

xm = (x₁ + x₂)/2

3 = (-4 + x₂)/2

Cross-multiplying, we have:

6 = -4 + x₂

x₂ = 6 + 4

x₂ of S = 10.

Midpoint on y-coordinate is given by:

ym = (y₁ + y₂)/2

3 = (-6 + y₂)/2

Cross-multiplying, we have:

6 = -6 + y₂

y₂ = 6 + 6

y₂ of S = 12.

Therefore, point S is equal to (10, 12).

We have proved that (2*10²)*(3*10⁵) = 3.5*10⁷+2.5*10⁷  .

In the given question

we have to prove that

(2*10²)*(3*10⁵) = 3.5*10⁷+2.5*10⁷

For proving we will solve the LHS and RHS separately and then equate them .

First Solving LHS

we have

=(2*10²)*(3*10⁵)

=(2*3)*(10²*10⁵)

=6*10²⁺⁵       ...( because aⁿ.aˣ = aⁿ⁺ˣ )

=6*10⁷    ...(i)

Now solving RHS

we have

=3.5*10⁷+2.5*10⁷

taking 10⁷ common , we get

=(3.5+2.5)*10⁷

Adding the terms in the bracket we get

=6*10⁷     ...(ii)

As we can see that from equation (i) and (ii) we have LHS=RHS

Hence proved that (2*10²)*(3*10⁵) = 3.5*10⁷+2.5*10⁷

Therefore , Proved that (2*10²)*(3*10⁵) = 3.5*10⁷+2.5*10⁷  .

Answer:

x = 0

Step-by-step explanation:

Distribute the left side

3x-6 = -6

Add 6 to both sides

3x = 0

Divide both sides by 3

x = 0/3

x = 0

Answer:

its 4+(-10)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Worth of furnishings = $1580

Tax rate = 4.5%

Tax = 4.5% × $1580 = 0.045 × $1580 = $71.10

Amount paid = $1580 + $71.10 = $1651.10

Since the decorator's fee was 12% of the purchases. This will then be calculated as:

y = kx

where,

y = decorators fee

k = percentage of decorators fee on purchases

x = amount paid

y = 12% × $1651.10

= 0.12 × $1651.10

= $198.132

there are 5040 ways by using permutations to select a president, vice-president, secretary and treasurer from 10 members on its board of directors.

Total members = 10

number of positions = 4

Now, we will use permutations.

So, we get that:

Number of ways = 10 × 9 × 8 × 7

Number of ways = 90 × 56

Number of ways = 5040 ways

Therefore, we get that, there are 5040 ways by using permutations to select a president, vice-president, secretary and treasurer from 10 members on its board of directors.

Step-by-step explanation:

Please check the attached graph.

From the diagram, it is clear that John is 5 ft tall is standing 20 feet away from a tree, making an angle of elevation to be 38⁰.

The diagram makes a right-angled triangle.

Pythagorean Theorem:

For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:

[tex]\:c=\sqrt{a^2+b^2}[/tex]

substituting a=5, b=20

[tex]c=\sqrt{5^2+20^2}[/tex]

[tex]c=5\sqrt{17}[/tex]

[tex]c=20.6[/tex] ft

Thus, the tree is 20.6 ft tall.
