Answer:
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set. further the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
I hope it will help =)
Answer:
L = 25
Step-by-step explanation:
Let's call the Length x and width x - 15 since the width is 15 less than length
Eric needs 70 of fencing in total, the perimeter of a rectangle is calculated by adding all sides
x + x + (x - 15) + (x - 15) = 70 add like terms
4x - 30 = 70 add 30 to both sides
4x = 100 divide both sides by 4
x = 25
The answer is $0.55
$8.50 is 100%.
x is 6.5%
8.50 : 100% = x : 6.5%
x = 8.50 : 100% * 6.5%
x = 0.5525
x ≈ $0.55
Answer:
1:4, 6:24
Step-by-step explanation:
Answer:
30.594
Step-by-step explanation:
To find perimeter we need to find the length of all the sides
The coordinates are A(-3,4), B(7,2), C(6,-3), D (-4,-1)
To find the length of side , we use distance formula
Side 
Side 
Side 
Side 
To find perimeter we add all the sides
10.198 + 5.099 + 10.198 + 5.099= 30.594
the perimeter of the rectangle= 30.594
