3 3/10 x $2.27 = $7.49 total cost of the fabric
------------------------------------------------------------------------------------
Ratio

Width : Length
2 : 5
Let x be the scale factor
Width : Length
2x : 5x
------------------------------------------------------------------------------------
Form equation and solve x
------------------------------------------------------------------------------------
Perimeter = 2(Length + Width)
70 = 2(5x + 2x)
70 = 2(7x)
70 = 14x
14x = 70
x = 5
------------------------------------------------------------------------------------
Find Length and Width
------------------------------------------------------------------------------------
Length = 5x
Length = 5(5)
Length = 25
Width = 2x
Width = 2(5)
Width = 10
------------------------------------------------------------------------------------
Answer: Length = 25 cm, Width = 10 cm
------------------------------------------------------------------------------------
The range is how much it spans in f(x), f(x) is a line, it has no max/min, so it's enough to substitute the least and greatest values of your domain:
f(-2) = -5, f(4)=7,
Range = [-5,7]
Answer:
5 roots (answer C)
Step-by-step explanation:
Any polynomial should have in the Complex Number System, as many roots as the polynomial's degree.
In our case, since we are dealing with a polynomial of order 5 (degree 5), it should have 5 roots in the Complex Number System.
Answer:
6 years
Step-by-step explanation:
6 = ⅕m
m = 30
"mother's age will be three times greater than daughter's age"—Not sure what "three times greater than" means. I will interpret it as: "mother's age will be three times daughter's age."
In x years, mother will be 30+x and the daughter will be 6+x.
30+x = 3(6+x) = 18+3x
12 = 2x
x = 6
In 6 years, the mother will be 36 and the daughter will be 12.
