It is given that, Kayke mixes 1/6 pound of salt with 1/8 bucket of water to make a saline solution.
With 1/8 bucket of water she mixes 1/6 pound of salt.
1/8 bucket of water = 1/6 pounds of salt
Now, using unitary method to find salt needed to use for a full bucket of water.
So,
1 bucket of water = 8/6 pounds of salt
= 1.34 pounds of salt.

A bathtub has 8 gallons of water in it. it is draining at a constant rate of 6 gallons every 5 minutes. write an equation that for the amount of water in the tub. when will it be empty?
If a bathtub has 8 gallons of water in it and it is draining at a constant rate of 6 gallons every 5 minutes. then the equation for the amount of water in the tub is f(x) =8-1.2x and it will take 6.67 minutes to drain the bathtub
Given,
The total quantity of water in the tub = 8 gallons
The quantity of water draining for every 5 minutes = 6 gallons
The quantity of water draining for every 1 minutes = [tex]\frac{6}{5} =1.2[/tex] gallons
Consider the number of minutes as x
Then the equation for the amount of water in the tub
f(x)= 8 - 1.2x
The number off minutes take to empty the tub = Total quantity of water / Quantity of water draining per minute
=[tex]\frac{8}{1.2}=6.67[/tex] minutes
Hence, if a bathtub has 8 gallons of water in it and it is draining at a constant rate of 6 gallons every 5 minutes. then the equation for the amount of water in the tub is f(x) =8-1.2x and it will take 6.67 minutes to drain the bathtub.

The required solutions are,
1) point A on the triangle is the center of dilation.
2) Triangle ABC is the original triangle.
The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°
Here,
1) As shown in the figure, after dilation the only initial point that does not change points A. So it could be concluded that point A is the center of dilation.
2) since the scale factor is of 1/2 implies that the dilated figure is lower than the size of the original figure hence, triangle ABC is the original triangle.

a car valued at $28,000 depreciates at a rate of 20% per year. what will the car be worth after 6 years?
The value of the car after 6 years will be $7340 .
The Depreciation can be calculated using the formula
A = P( 1 - r/100)ⁿ
where , A = amount , P = principal , r = rate of deprecation , n = time period
In the question ,
it is given that
the value of the car (P) = $28000
rate of deprecation (r) = 20% per year
time period (t) = 6 years
Substituting the values in the Depreciation formula we get ,
Amount = 28000*( 1 - 20/100 )⁶
= 28000*(80/100)⁶
= 28000*(0.80)⁶
= 28000*0.26214
= 7339.92
≅ 7340
Therefore , the value of the car after 6 years will be $7340 .

The graph of a quadratic function touches, but does not cross, the x-axis at x = 4. Which function represents this
situation?
Oy=x²-16
Oy=x²-4x
Oy=x²-8x+16
O y=x² + 8x + 16
Correct answer is C. y = x2 - 8x + 16 is the quadratic equation.
How do you figure out the equation?The answer to the question is:
x = 4
The graph has a multiplicity of 2 at x = 4 since it only touches this value and does not cross it.
The equation is then shown as follows:
y = (x - 4)^2
Expand
y = x^2 - 8x + 16
The quadratic equation is y = x2 - 8x + 16 as a result.

The definition of the composition between the two functions f and g is presented below:
f ° g (x) = f( g(x) ) (1)
Where x is the input variable of the composite function.
In other words, the input of the function f is the output of the function g.
Now we proceed to find the expressions of the each of the two cases:
Case 1
g ° f (x) = g( f(x) )
g ° f (x) = 4 · (2 · x + 2) - 3
g ° f (x) = 8 · x + 8 - 3
g ° f (x) = 8 · x + 5
Case 2
h ° g (- 3 · x) = h [g (- 3 · x)]
h ° g (- 3 · x) = 3 · [4 · (- 3 · x) - 3]
h ° g (- 3 · x) = 3 · (- 12 · x - 3)
h ° g (- 3 · x) = - 36 · x - 9
Case 3
f ° g (- 3) = f( g(- 3) )

The kind of transformation which converts the graph of f(x) into the graph of g(x) is vertical shrink .
What is transformation in graph?
A graph transformation is a procedure that modifies an existing graph or graphed equation to create different version of the following graph.
It is given that the functions are :
f(x) = -9(x+6)2 - 3
g(x) = -9(x-4)2 - 3
We know that if we perform transformation that meant the graph of f(x) is transformed into the graph of g(x).
i.e.,
f(x) = -9(x+6)2 - 3
f(x) = -18(x+6) - 3
f(x) = -18x - 128 - 3
f(x) = -18x - 72 - 56 - 3
f(x) = -9(x-4)2 - 3 - 56
f(x) = g(x) - 56
or g(x) = f(x) + (-56)
So , as we are adding f(x), this suggests that the transformation is one of the vertical shrink type.
