Answer:

d =  \sqrt{(x2 - x1) {}^{2} + (y2 - y1) {}^{2}  }

Step-by-step explanation:

d =  \sqrt{( - 4 + 3) {}^{2} + (7 - 9) {}^{2}  }

d =   \sqrt{(1 + 4)}  =  \sqrt{5}

What is the value of x in the figure?
finlep [7]
<h3>Answer:  x = 29</h3>

======================================================

Work Shown:

x+61 = 90

x+61-61 = 90-61

x = 29

------------

Explanation:

  • The first step is valid because the two angles x and 61 are complementary angles. They form a right angle or 90 degree angle.
  • In the second step, I subtracted 61 from both sides to undo the "+61".

Using the midpoint method, calculate the price elasticity of demand of Good Z using the following information: When the price of
exis [7]

Answer: (B) The price elasticity of demand for good Z = 0.86

Step-by-step explanation:

The formula for determining elasticity of demand by using the midpoint method is

(Q2 - Q1)/[(Q2 + Q1)/2] / (P2 - P1)/[(P2 + P1)/2]

Where

P1 is the initial price of the item.

P2 is the final price of the item.

Q1 is the initial quantity demanded for the item.

Q2 is the final quantity demanded for the item.

From the information given,

P1 = 10

P2 = 15

Q1 = 85

Q2 = 60

The price elasticity of demand for good Z = (60 - 85)/[(60 + 85)/2] / (15 - 10)/[(15 + 10)/2]

= (-25/72.5) / (5/12.5) = -25/72.5 × 12.5/5

= - 312.5/362.5 = - 0.86
