(Type an integer or a decimal.)
Answers
Using proportions, it is found that the hedgehog loses 3.45 ounces after 115 days of hibernation.
A proportional relationship is modeled by:
[tex]y = kx[/tex]
In which k is the constant of proportionality.
In this problem, the ratio between the weighs loss after x days in hibernation is given by:
[tex]k = \frac{0.24}{8} = \frac{0.84}{28} = \frac{2.25}{75} = \frac{2.79}{93} = 0.03[/tex]
Since this ratio is constant, the relationship is proportional, modeled by:
[tex]y = 0.03x[/tex]
The weight lost after 115 days of hibernation is y(115), hence:
[tex]y = 0.03(115) = 3.45[/tex]
The hedgehog loses 3.45 ounces after 115 days of hibernation.

The parabola has a minimum value of (1. 5,-1. 5). What is its equation.
Answers
The minimum point of a parabola is its vertex.
The equation of the parabola is [tex]\mathbf{y =a(x -1.5)^2 -1.5}[/tex]
The minimum point of the parabola is given as:
[tex]\mathbf{Minimum = (1.5,-1.5)}[/tex]
This represents the vertex (h,k).
So, we have:
[tex]\mathbf{(h,k) = (1.5,-1.5)}[/tex]
A parabola is represented with the following equation
[tex]\mathbf{y =a(x -h)^2 + k}[/tex]
Substitute values for h and k
[tex]\mathbf{y =a(x -1.5)^2 -1.5}[/tex]
Hence, the equation of the parabola is [tex]\mathbf{y =a(x -1.5)^2 -1.5}[/tex], where a does not equal to 0

10x − 10y = –20
–10x + 4y = –16
Answers
Step-by-step explanation:
10x - 10y = -20
-10y = -20 - 10x
y = -20/-10 - 10x/-10
y = 2 + x
-10x + 4y = -16
-10x + 4(2 + x) = -16
-10x + 8 + 4x = -16
-6x = -24
x = -24/-6
x = 4
y = 2 + x

_x =–4x–25
_x +4x=–25
(4+_x) = -25

The correct expression is: 12÷(2+2/3)²
We need to evaluate given expression.
Consider given expression,
12 ÷ (2+2/3)²
= 12 ÷ (8/3)²
= 12 ÷ 64/9
= 12/(64/9)
= 12 * (9/64)

Step-by-step explanation:
For each year , the population of a forest of trees is represented by A(t)=115(1.025)t .In a neighboring forest, the population of the same type of tree is represented by the function B(t)=82(1.029)t .
Assuming the population growth models continue to represent the growth of the forests, which forest will have a greater number of trees after 100 years? By how many?
Answers
Answer: Forest B has 71 more trees than forest A after 100 years.
Step-by-step explanation:
I'm assuming that both functions should read as follows: (the time, t, is shown as a power, instead as a multiplication).
A(t)=115(1.025)^t
B(t)=82(1.029)^t
Although A starts out with more trees (115), B is growing at 2.9% per year [1.029], versus 2.5% [1.025]for A.
A(100)=115(1.025)^(100)
A(100) = 1359
B(100) = 82(1.029)^(100)
B(100) = 1430
Forest B has 71 more trees than forest A after 100 years.
