OVERDUE The width of a row of identical townhouses, y, and the number of townhouses, x, have a proportional relationship. The width of 5 townhouses is 105 ft.

a. What is the constant of proportionality?

b. Write an equation that relates the width of a row of townhouses and the number of townhouses.

c. What would be the width of 9 townhouses in feet?

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

10

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
