Answer:
Step-by-step explanation:
1). Let the circumference C and area A of the circle are proportional,
C ∝ A
C = kA
Here k = proportionality constant
k = [tex]\frac{C}{A}[/tex]
From the given table,
For C = 25 cm, A = 50 cm²
Then the value of k = [tex]\frac{25}{50}[/tex]
k = [tex]\frac{1}{2}[/tex]
For C = 50 cm, A = 201 cm²
k = [tex]\frac{50}{201}[/tex] ≈ [tex]\frac{1}{4}[/tex]
In both the cases proportionality constant is giving the different values.
Therefore, Circumference and Area of the circular objects are not proportional.
2). If A = [tex]\frac{1}{2}\times r\times C[/tex]
Then this equation will be true for all the values of r and C given in the table.
For r = 4 cm and C = 25 cm
A = [tex]\frac{1}{2}\times 4\times 25[/tex] = 50 cm²
For r = 8 cm and C = 50 cm
A = [tex]\frac{1}{2}\times 8\times 50[/tex]
A = 200 cm²
True for all values of 'r' and 'C'.

Describe the transformation of the graph y = -(x-4)^3 +5
Answers
shift right 4 units
shift up 5 units
Graph has been transformed from the graph of y = x³ by a horizontal shift of 4 units to the right then by a reflection over the x-axis, and 5 units upward of vertical shift.
What is a function?A function from a set X to a set Y assigns to each element of X exactly one element of Y.
The given function is y = -(x-4)³ + 5.
Let us use algebraic methods to understand the transformation of the graph of this function.
First, we can observe that the parent function is y = x³ has been transformed to y = -(x-4)³ by replacing x with (x-4).
This transformation gives a horizontal shift of the graph of 4 units to the right.
then negative sign in front of the function reflects the graph over the x-axis, resulting in an upside-down graph.
Finally, the entire graph is shifted vertically upward by 5 units, as observed by the constant term +5 in the equation.
Hence, the graph has been transformed from the graph of y = x³ by a horizontal shift of 4 units to the right then by a reflection over the x-axis, and 5 units upward of vertical shift.

Which value for b makes the equation b/4 =12 true?
Answers
48 would be in that place because 12 x 4 would get you to 48, which means that 48 is the answer for this one. Hope this helped. I had to edit the answer out because it glitched, sorry :/
The value for b that makes the equation b/4 = 12 true is b = 48.
We have to find the value for b that makes the equation b/4 = 12 true, we can solve for b by multiplying both sides of the equation by 4.
b is the variable in the equation.
b/4 = 12
Multiply both sides by 4:
4 × (b/4) = 4 × 12
This simplifies to:
b = 48
Therefore, the value for b that makes the equation b/4 = 12 true is b = 48.

Step-by-step explanation:
I got it right on edugenity
The solution to the inequality g > 0.50 is all numbers to the right of 0.50, excluding 0.50 itself.
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.
We are given that;
Function g > 0.50
Now,
To graph the inequality g > 0.50, we start by drawing a number line from negative 2 to positive 2.
Next, we need to indicate the solution region on the number line. The inequality g > 0.50 means that g is greater than 0.50 but not equal to 0.50. So, we draw an open circle at 0.50 to indicate that it is not included in the solution region. Then, we shade all numbers to the right of 0.50, since they are greater than 0.50.
To check the solution, we can substitute any number greater than 0.50 into the inequality and check that it is true. For example, if we substitute 1 into the inequality, we get:
1 > 0.50
This is true, so 1 is in the solution region.
If we substitute -1 into the inequality, we get:
-1 > 0.50
This is false, so -1 is not in the solution region.
Therefore, the answer of the given inequality will be all numbers to the right of 0.50, excluding 0.50 itself.
