To determine the scale factor of the dilation, we determine the distances between the endpoints of the two lines through the equation,
                            d = √(x₂ - x₁)² + (y₂ - y₁)²
 Substituting the known values.

Line Segment 1:     d = √(1 - 2)² + (4 - 8)²  = 4.123

Line Segment 2:     d = √(18 - 14)² + (12 - 1)² = 11.70

Dividing the answers will give us 0.352

the mendez family just bought a home for 180,000 if the value of the home increases at a rate of 3% per year, use an exponential
just olya [345]

Answer:

241904.9483

≈ 241905

Step-by-step explanation:

Given that,

current amount of house = 180,000

value of the home increases at a rate of 3% per year

To find,

approximate value of the home after 10 years using exponential function

<h2>Equation</h2><h2>a(1 + r)^t</h2>

where a is the amount of house = 180,000

r is the interest rate per annum = 3% = 3/100 = 0.03

t is the number of years = 10

180,000 (1+0.03)^10

180,000 (1.03)^10

241904.9483

≈ 241905

write the formula used to find length when the breadth height and volume are known........breadth when the length height and vol
sdas [7]

Answer: L = V/bh

b= V/Lh and h= V/Lb

Step-by-step explanation: V = Lbh or V= lwh is also used for the Basic form for the Volume of a cube or rectangular prism is

Volume = Length × breadth × height

The volume will be expressed as cubic units such as cubic meters cubic feet. Sometimes abbreviations are used like cm^3 for cubic centimeters.

When you know the Volume, and you need to find a missing dimension, just make a fraction with the V in the numerator and the dimensions you know in the denominator. This means you are dividing the Volume by the area of the dimensions you have been given to find the missing dimension.
