Answer:
28 will be your answer!
Step-by-step explanation:
I don't properly know how to explain thia but i know its the answer
We are comparing areas, so square of the linear dimension
Relative cost per unit area
12^2/6=24
16^2/10=256/10=25.6
Since 24<25.6, the 12" pizza is a better deal.
Note: we could compare exact area by calculating A=pi (d^2)/4, but since it is a relative comparison, the result will be the same, albeit more work.
Answer:
2.19 ft ( approx )
Step-by-step explanation:
Let x be the width ( in ft ) of the path,
Given,
The dimension of the garden area,
Length = 30 ft, width = 20 ft,
So, the dimension of the remaining garden ( garden excluded path ),
Length = (30 - 2x) ft, width = (20-2x) ft
Thus, the area of the remaining garden,
A=(30 - 2x)(20 - 2x)
According to the question,
A = 400 ft²,
By the quadratic formula,
⇒ x ≈ 22.8 or x ≈ 2.19,
∵ Width of the path can not exceed 30 ft or 20 ft
Hence, the width of the path is approximately 2.19 ft.
Answer: g(x) = (x - 1)^3
Step-by-step explanation:
There is a transformation called "horizontal translation"
For an initial function f(x), a horizontal translation of N is written as:
g(x) = f(x - N)
where if N is positive, we have a translation of N units to the right.
If N is negative, we have a translation of N units to the left.
Here, we can see that:
f(x) = x^3, such that when x = 0, f(0) = 0.
And g(x) seems to be a horizontal translation of f(x) (because the graph of g(x) is equidistant to the graph of f(x)), then:
g(x) = (x - N)^3
And we can see that when x = 0, g(0) = 1
Then:
g(0) = (0 - N)^3 = 1
N^3 = 1
N = ∛1 = 1
Then the equation for g(x) is:
g(x) = (x - 1)^3
