Mathematics

Mrrafil [7]3 years ago

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points A(-7, a) and B(c, d).

Substitute:

m=\dfrac{d-a}{c-(-7)}=\dfrac{d-a}{c+7}

Exception: c ≠ -7.

Consider two points in a two dimensional coordinate plane

(x_{1},y_{1})\text { and }  (x_{2},y_{2})

As you know mid point of a line joining two points is the coordinate of the middle point of only that portion of line joining between two points.

[tex]\text   { Mid point of  }  (x_{1},y_{1})\text { and }  (x_{2},y_{2}) =(\frac{x_{1}+x_{2}}{2} ,\frac{y_{1}+y_{2}}{2})[/tex]

As we know distance formula gives the Distance between line joining two points in two dimensional coordinate system.It is always positive.

[tex]\text   { Distance formula between two points  }  (x_{1},y_{1})\text { and }  (x_{2},y_{2}) =\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]

Distance formula gives the distance between two points, whereas Mid point formula gives coordinate of the middle point.

What is the best example of elasticity demand in the context university of rwanda
WINSTONCH [101]

Answer:

Step-by-step explanation:

<u>Elasticity Demand</u>

  • The flexibility of interest is a significant minor departure from the idea of interest. Request can be delegated as versatile, inelastic, or unitary.
  • Flexible interest is one in which the adjustment of the amount requested because of an adjustment of cost is huge. An inelastic interest is one in which the adjustment of the amount requested because of an adjustment of cost is little.
  • The equation for processing versatility of interest is:

(Q1 - Q2)/(Q1 + Q2)

(P1 - P2)/(P1 + P2)

  • In the event that the recipe makes an outright worth more prominent than 1, the interest is flexible. At the end of the day, the amount changes quicker than the cost. On the off chance that the worth is under 1, the request is inelastic. All in all, the amount changes more slowly than the cost. In the event that the number is equivalent to 1, the flexibility of interest is unitary. All in all, the amount changes at a similar rate as the cost.
  • An illustration of items with a flexible interest is purchaser durables. These are things that are bought inconsistently, similar to a clothes washer or an auto, and can be deferred assuming the cost rises. For instance, vehicle refunds have been extremely fruitful in expanding car deals by diminishing costs.

What does x equal? <br><br><br> This question is found on Khan academy.
Sauron [17]

Answer:

Hi there!

The correct answer is 95°

Step-by-step explanation:

Okay if you look at the picture, 95 degrees' supplementary angle is 85 degrees. A supplementary angle means it adds up to 180°. So that means the angle that is supplementary to 85 is 95. **Keep in mind since they did not tell that the sides are parallel you cannot assume that 95° and angle x° are vertical so this is the safest way to solve the problem**

alisha [4.7K]

Answer:

The correct answer is D) 360 possible arragements.

Step-by-step explanation:

To solve the problem, we use the slot method. There are 6 possibilities:

Possibility N°1: J _ _ _ _ _  (Joey is first in the line)

Possibility N°2: _ J _ _ _ _  (Joey is second in the line)

Possibility N°3: _ _ J _ _ _  (Joey is third in the line)

Possibility N°4: _ _ _ J _ _  (Joey is fourth in the line)

Possibility N°5: _ _ _ _ J _  (Joey is fifth in the line)

Possibility N°6: _ _ _ _ _ J (Joey is sixth in the line)

Frankie must always stand behind Joey.

Possibility N°1: there are 5! possible arragements , 5!=120

Possibility N°2: Frankie can't be ahead of Joe, so possible cases, 5! - 4! = 120 -24 = 96

Possibility N°3: Frankie can't take be at the first two positions, so 5! - 2×4! = 120 -48 = 72

Possibility N°4: Frankie can't take the at the first three, so 5! - 3×4! = 120 - 72 = 48

Possibility N°5: Frankie can't take be at first 4, so 5! - 4×4! = 120-96 = 24

Possibility N°6: It does not satisfy the criteria.

The sum the possibilities is 120+96+72+48+24=360 possible arragements.
