A person 1.85 m tall walks towards a lamppost on level ground at a rate of 0.5 m/sec. The lamp on the post is 5 m high. At which rate is the tip of the person's shadow moving toward the lamppost when the person is 4 I from the post? Please enter your answer in decimal format with three decimal places.
Using the Pythagorean Theorem and implicit differentiation, it is found that the tip of the person's shadow is moving toward the post at a rate of 0.393 m/sec when the person is 4 m from the post.
What is the Pythagorean Theorem?The Pythagorean Theorem is a geometry axiom that relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, stating that the hypotenuse squared is the sum of the legs squared, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In the context of this problem, we have that:
The distance d between the person's shadow and the lamp is the hypotenuse of a right triangle.The legs are the person shadow and the lamp.Hence the following relation between these variables is established:
d² = x² + y².
Applying implicit differentiation, the rate of change of the distance is given as follows:
[tex]d\frac{dd}{dt} = x\frac{dx}{dt} + y\frac{dy}{dt}[/tex]
The height remains constant, hence:
[tex]\frac{dy}{dt} = 0[/tex]
The other parameters are given as follows:
y = 5 - 1.85 = 3.15 m (vertical distance).x = 4 m (distance of the person from the post).dx/dt = 0.5 m/s (velocity of the person).Hence the distance at the desired instant is:
d² = 4² + 3.15²
d = sqrt(4² + 3.15²)
d = 5.091 m
The rate of change of the distance is found as follows:
5.091dd/dt = 4 x 0.5
dd/dt = 2/5.091
dd/dt = 0.393 m/sec.

Write a polynomial function f of least degree that has rational coefficients, a leading
coefficient of 1, and the given zeros of -1, 2, and -3i. Show all work.
The least degree polynomial function with rational coefficients and the given zeros, -1, 2 and 3i is f(x) =[tex]x^{2} -x -2(\sqrt{x} -9)[/tex]
What do we mean by polynomial function?
A polynomial function is one that involves only non-negative integer powers or positive integer exponents of a variable in an equation such as the quadratic equation, cubic equation, and so on.
For example, 2x+5 is a polynomial with an exponent of one.
So given zeroes are -1 , 2 and 3i
We have,
x = -1
x +1 =0
Similarly for 2
x = 2
x -2 = 0
Again, For 3i
We have, x = 3i
Rewrite as x = [tex]\sqrt{-9}[/tex]
For easy calculation, squaring on both sides
[tex]x^{2} = -9[/tex]
[tex]x^{2} +9[/tex] =0
So, the polynomial has the function:
(x + 1)(x - 2) ([tex]\sqrt{x} -9[/tex])
[tex]x^{2} - 2x +x -2 (\sqrt{x} -9)\\x^{2} -x -2(\sqrt{x} -9)\\[/tex]
Therefore, the least degree polynomial function with rational coefficients and the given zeros, -1, 2 and 3i is f(x) =[tex]x^{2} -x -2(\sqrt{x} -9)[/tex].

graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to c is 4/5. in other words a change of 1 unit in x corresponds to a change of 4/5 units in y
The graph that represents the proportional relationship between x and y with a unit rate of 4/5 is shown in the image below.
How to Graph the Line of a Proportional Relationship?If the relationship between x and y is a proportional relationship, the equation that models the relationship between x and y can be expressed as y = mx. Here, the unit rate is represented by the value of in the equation.
This means that, the graph that represents the proportional relationship between x and y would have a slope of the value of m. m, which is the slope of the line, is the ratio of the rose of the line to the run of the line.
Thus, where m = 4/5, the equation that represents the proportional relationship would be:
y = 4/5x.
Therefore, the graph below shows the proportional relationship between x and y which is represented by the equation, y = 4/5x.

Find the equation of a parabola with a focus of (0, 15) and directrix y = –15.
The equation of the parabola is x² = 60y after applying the concept of the parabola.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
(x - h)² = 4a(y - k)
(h, k) is the vertex of the parabola:
a = √[(c-h)² + (d-k²]
(c, d) is the focus of the parabola:
It is given that:
Focus of (0, 15) and directrix y = –15.
Let (x, y) be on the parabola:
The distance between focus and (x, y):
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\rm d=\sqrt{(x-0)^2+(y-15)^2}[/tex]
[tex]\rm d=\sqrt{x^2+(y-15)^2}[/tex]
Directrix y = -15
y + 15 = 0
[tex]\rm \sqrt{x^2+(y-15)^2} = |y + 5|[/tex]
Squaring both sides:
x² + (y - 15)² = (y + 15)²
x² + y² -30y + 225 = y² + 30y + 225
x² -30y = 30y
x² = 30y + 30y
x² = 60y

What is defined by the term transformation?Image transformations usually involve the modification of various bands of data, either from a single source images or from two or more images acquired at different times of the same area.We were provided a graph of the function f(x).
g(x) = 2f is another function definition (x -1).
Now we must use the drawing tool(s) to create the proper graph of a function g(x) = 2f (x -1).
which can be discovered through transformation.
f(x) becomes f (x-1)
Then, f(x-1) becomes 2f (x-1)
f(x-1) shifts this same graph of f(x) by one unit to the right.
Whereas 2f(x-1) extends the graph of f(x-1) by a factor of 2. So we just need to double the y-coordinates of the points on the graph.
As a result, the finished graph of g(x) would be as seen in red.

Jolene invests her savings in two bank accounts, one paying 4 percent and the other paying 12 percent simple interest per year. She puts twice as much in the lower-yielding account because it is less risky. Her annual interest is 8740 dollars. How much did she invest at each rate?Amount invested at 4 percent interest is $Amount invested at 12 percent interest is $
We will have the following:
First, we recall that the simple interest formula is given by:

[tex]r=6+3\sin \theta[/tex]Let's graph the equation.
Apply the formula:

a = 6
b = 3
Thus, we have the following:
Subsitute -θ for θ to know thw axis of symmetry:
[tex]\begin{gathered} r=6+3\sin (-\theta) \\ \end{gathered}[/tex]Now, solve for θ = 1 and -1:
[tex]\begin{gathered} r=6+3\sin (1) \\ r=6.05 \\ \\ r=6+3\sin (\text{ -1)} \\ r=5.94 \end{gathered}[/tex]Since sinθ is not equal to sin(-θ), the pole will be the point of symmetry.
To find the x-intercept, substitute 0 for θ:
[tex]\begin{gathered} r=6+3\sin \theta \\ \\ r=6 \end{gathered}[/tex]Hence, the limacon will cross the x-axis on both sides at x = 6 and -6.
Since the addition is with the sine function, the limacon will face down.
Now, input different values for θ and solve for r.
We have:
When θ = pi/2:
[tex]r=6+3\sin (\frac{\pi}{2})=9[/tex]When θ = pi:
