Answer:
Given the function in the question
f(x) = |x-3| + 2
a) state the name of the function
Absolute value function
since it is similar to f(x) = |x|
b) identify the independent and dependent variable
x = independent variable (input variable)
f(x) or y = dependent variable (output variable)
The variable which we assign the value we call the independent variable, and the other variable is the dependent variable, since it value depends on the independent variable.
c) identify the rule
A function is an equation that has only one answer for y for every x.
d) evaluate the function
given x = -5
f(-5) = |-5 - 3| + 2
= |-8| + 2
= 8 +2
= 10
The equation of the line passing through those two points is y=0x+1
Answer: Area of sidewalk is 217m²
Step-by-step explanation:
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle
π is a constant whose value is 3.14
A circular flower bed is 20 meters in diameter.
radius = diameter/2 = 20/2 = 10 meters
Area of the flower bed = 3.14 × 10²
= 314m²
The circular flower bed has a circular sidewalk around it that is 3 meters wide. This means that the total diameter would be
3 + 20 + 3 = 26m
Radius = 26!2 = 13m
Total area = 3.14 × 13² = 530.66m²
Therefore, area of the sidewalk is
530.66 - 314 = 216.66
The area of sidewalk is 217m² to the nearest whole number
