The constant of proportionality between 3.56 and 13.35 is 3.75 using the formula C = y/x.
What is the Constant of Proportionality?If the corresponding elements of two sequences of numbers, frequently experimental data, have a constant ratio, known as the coefficient of proportionality or proportionality constant, then the two sequences of numbers are proportional or directly proportional.
When two variables are directly or indirectly proportional to one another, their relationship can be expressed using the formulas y = kx or y = k/x, where k specifies the degree of correspondence between the two variables.
The proportionality constant, k, is often used.
So, the Constant of Proportionality is as follows:
C = y/x
Now, insert values as follows:
C = y/x
C = 13.35/3.56
C = 3.75
Therefore, the constant of proportionality between 3.56 and 13.35 is 3.75 using the formula C = y/x.

Find the age of the mammal hide to the nearest year.
Enter the correct answer.
The age of the mammal hide is 3567 years
How do you use radioactivity to find age?Radioactivity can be used to determine the age of rocks, minerals, and fossils through a method called radiometric dating. This method is based on the principle that certain isotopes of elements decay at a known rate over time, producing new isotopes. By measuring the relative amounts of the original parent isotope and the newly formed daughter isotope, scientists can determine how much time has passed since the rock, mineral, or fossil was formed.
0.70 = 1 * e^-0.0001t
Take the logarithm of both sides:

If y varies directly as x, and y is 12 when x is 1. 2, what is the constant of variation for this relation? 1.
The constant of variation for this relation is 10.
If y varies directly as x, we can write it as y = kx, where k is the constant of variation. This constant represents the relationship between x and y, and it determines how much y changes for a given change in x.
To find the constant of variation, we need to know the value of y and x. In this case, we are told that y is 12 when x is 1.2. Using this information, we can solve for k by dividing both sides of the equation by x:
y = kx
12 = k * 1.2
12 / 1.2 = k
k = 10
So the constant of variation is 10. This means that for every change of 1 in x, y will change by 10. In other words, if x increases by 1, y will increase by 10, and if x decreases by 1, y will decrease by 10.

What is the standard form of the equation of the parabola with focus: (0, 7) and the vertex at the origin?.
The standard form of the equation of the parabola with focus (0, 7) and the vertex at the origin is y = 1/28 x² + 7
A parabola is a symmetrical U-shaped curve that is defined by the set of all points that are equidistant to a fixed point, called the focus, and a straight line called the directrix. In a parabolic equation, the focus and the vertex are important points that determine the shape and position of the parabola.
In the case of the parabola with focus (0, 7) and the vertex at the origin (0,0), we can use the standard form of the equation of a parabola to write its equation. The standard form of a parabola is given by:
y = a(x - h)² + k
Where (h,k) is the vertex of the parabola and a is the coefficient that determines the direction and width of the parabola. To write the equation of this parabola, we need to find the value of a.
Since the focus is (0, 7) and the vertex is (0,0), we can use the formula:
a = 1/(4f)
Where f is the distance from the vertex to the focus. In this case, f = 7. Therefore, a = 1/(4 * 7) = 1/28.
Finally, we can substitute these values into the standard form to get the equation of the parabola:
y = 1/28 x² + 7

Marco's charges an additional fee for toppings, but all toppings cost the same. Kevin got pepperoni, banana peppers, and black olives on his pizza for a cost of $15.74. Brian ordered mushrooms and eggplant on his pizza and paid $14.49. Using this information, write an equation for the cost of a pizza, C, as a function of the toppings, t, ordered.
Answer: Let's use x to represent the cost of each topping. Then, the cost of a pizza with t toppings can be expressed as:
C = x * t + 15
We know that Kevin's pizza with 3 toppings cost $15.74, so we can write an equation using this information:
15.74 = 3x + 15
Solving for x, we get:
x = (15.74 - 15) / 3 = 0.74
So, each topping costs $0.74. Now we can use the information about Brian's pizza to check our answer:
14.49 = 2x + 15
Substituting x = 0.74, we get:
14.49 = 2 * 0.74 + 15
Which simplifies to:
14.49 = 1.48 + 15
This confirms that x = 0.74 is the correct cost for each topping. Therefore, the equation for the cost of a pizza as a function of the toppings ordered is:
C = 0.74t + 15

How to solve this first order linear differential equation?
To find first-order linear differential equations solution, we have to derive the general form or representation of the solution.
With the help of the steps shown below, we can learn how to solve the first-order differential equation.
1. Reorder the terms in the given equation so that they have the form [tex]$\frac{dy}{dx}+Py=Q[/tex] where P and Q are constants or functions of the independent variable x only.
2. Integrate P (obtained in step 1) with respect to x and then put this integral as a power of e to determine the integrating factor.
[tex]$e^{\int P d x}[/tex] = IF
3. The linear first-order differential equation's two sides should be multiplied by the IF.
4. The L.H.S of the equation is always a derivative of [tex]$y \times M(x)$[/tex] i.e. L.H.S [tex]$= \frac{d(y \times I . F)}{dx}[/tex]
[tex]$d(y \times I . F) d x=Q \times I . F$[/tex]
5. In order to arrive at the solution, we simply integrate both sides with respect to x in the last step.
Therefore [tex]y \times I . F=\int Q \times I . F d x+C$,[/tex]
where C is some arbitrary constant
Similarly, we can also solve the other form of linear first-order differential equation [tex]$\frac{dy}{dx}+Py=Q[/tex] using the same steps.

what are the spike regression nonlinear constraints
Spike-and-slab regression is a method used to model the relationship between a response variable and a set of predictor variables, and nonlinear constraints can be applied to the model to specify relationships between the predictor variables, such as monotonicity or convexity.
Spike-and-slab regression is a statistical method used to model the relationship between a response variable and a set of predictor variables, where the predictor variables are partitioned into two groups: a set of important predictors (spikes) and a set of unimportant predictors (slabs). Nonlinear constraints can be applied to the model to specify relationships between the predictor variables, such as monotonicity or convexity. These constraints can be used to enforce prior knowledge or assumptions about the relationships between the predictor variables, and can help to improve the accuracy and interpretability of the model. Examples of nonlinear constraints that can be used in spike-and-slab regression include the convexity constraint and the total variation penalty.

A line graph, because it would show the association or relationship between two variables
A line graph, because it would show how a variable changes over time between each data point given
Answer:
A - scatter plot; it would show the relationship
Step-by-step explanation:
You want to determine if a scatter plot or line graph is a more appropriate way to represent the relationship between a manatee's weight and height.
VariablesThe variables of concern in the data are weight and height. Time is not involved. (Eliminates choices B and D.)
Functional relationshipIt seems likely there may not be a functional relationship between weight and height. That is, manatees of the same weight may have different height, and vice versa. This suggests a line graph would not be a useful way to represent the relationship
Scatter plotA scatter plot in this case would be used to relate weight on one axis to height on the other axis. Any relationship between them would show up as grouped data points, or data points that generally fall on a line or curve.
Since the "marine biologist [is] interested in seeing the relationship between a manatee's weight and height", ...
A scatter plot [is more appropriate] because it would show the association or relationship between the two variables.

the quadrilateral is a trapezoid. what is the value of x? a) 4. b) 5. c) 48. d) 25.
The quadrilateral is a trapezoid. The value of x is 5 by applying midsegment theorem for trapezoids.
The midsegment of a trapezoid is parallel to each base and its length is one half the sum of the lengths of the bases.
The side with length 21 units and 27 units are parallel to each other.
From the given diagram, the expression below is true:
5x-1 = (21 + 27)/2
2(5x - 1) = 21 + 27
10x - 2 = 48
10x = 48 + 2
10x = 50
Divide both sides by 10
x = 50/10
x = 5

The circle x2 + y2 – 18x + 8y + 48 = 0 is translated one unit right and two units down. Which is the radius and center of the translated circle?
The radius and center of the translated circle are,
Radius = 7 units
Center = (10, - 2)
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
The equation of circle is,
x² + y² - 18x + 8y + 48 = 0
Now, We can simplify the equation as;
x² + y² - 18x + 8y + 48 = 0
x² - 18x + 81 - 81 + y² + 8y + 16 - 16 + 48 = 0
(x - 9)² + (y + 4)² = 49
(x - 9)² + (y + 4)² = 7²
Hence, The radius of circle = 7
And, Center = (9, - 4)
Let the center of circle after translated one unit right and two units down is, (h', k')
Hence, We get;
h' = 9 + 1 = 10
k' = - 4 + 2 = - 2
Thus, The equation of the translated circle is,
(x - 10)² + (y - (- 2))² = 7
Hence, the radius and center of the translated circle are,
Radius = 7 units
Center = (10, - 2)
