A streetlight is at the top of an 18ft tall pole. A woman 6 ft tall walks away from the pole at a speed of 4 ft/sec along a straight path. How fast (in ft/sec) is the tip of her shadow moving away from the pole when she is 45 ft from the base of the pole
Answers
The woman's shadow is moving away from the pole at the speed of 4 feet/sec.
Calculating the value of shadow speedThe height of a pole-mounted street light = 18 ft
The height of a lady = 6 ft
The woman is moving quickly and directly away from the pole. Her speed = 4ft/sec.
The woman's distance from the pole at the precise moment question want to know the speed of the woman's shadow's leading edge = 45ft
A woman standing 6 feet tall moves away from the pole in a straight route at a pace of 4 feet per second. If we assume that t is the passing time in seconds and that x is the distance in feet between the pole and the lady, we are informed that dx/dt=4 ft/sec.

Answers are 1/3, 1/2, and 1/4 (not respectively). But can someone tell me how to get there please?
Answers
The value of X is 1/3 and Y is 1/2 and Z is 1/4.
According to the statement we have given the equations which are
X + Y = 5XY -(1)
Y + Z = 6YZ -(2)
Z + X = 7XZ -(3)
and we have to find the value of X,Y,Z.
So, solve the equations for the X,Y,Z
From (1) equation
Y = X / (5X-1) -(4)
From (3) equation
Z = X / (7X-1) -(5)
Put (4) and (5) in (2) then
X / (5X-1) + X / (7X-1) = 6{[X / (5X-1)][X / (7X-1)]}
X(7X-1) + X(5X-1) = 6{[X / (5X-1)][X / (7X-1)]} / {[1 / (5X-1)][1 / (7X-1)]}
Then after solving
12(X)^2 -2X = 6(X)^2
6(X)^2 -2X = 0
X (6X-2) = 0
X = 0, X = 1/3
Here X = 0 is neglected.
So, X=1/3 -(6)
Put (6) in (4) and (5) then
From 4
Y = X / (5X-1)
Y = (1/3) / (5(1/3)-1)
Y = (1/3) / (2/3)
Y = 1/2.
From (5) equation
Z = X / (7X-1)
Z = (1/3) / (7(1/3)-1)
Z = (1/3) / (4/3)
Z = 1/4.
So, The value of X is 1/3 and Y is 1/2 and Z is 1/4.

A triangle has vertices at coordinates $(11,1)$, $(2,3)$ and $(3,7)$. What is the number of units in the length of the longest side of the triangle
Answers
Answer:
10 units
Step-by-step explanation:
the longest length is from (11, 1) to (3, 7) and can be clearly shown when graphed
now to find the length you must use the pythagorean theorem
the distance between 11 and 3 is 8 and the distance between 1 and 7 is 6 so
8^2 + 6^2 = c^2
64 + 36 = c^2
100 = c^2
c = 10

For decades, hoax artists have been going out into grain fields to make crop circles like the one shown below. Though many people believed these crop circles to be the work of aliens we now know that these designs were made by people with very simple tools and some geometric knowledge. To make each circle, one person stands stationary in a field holding a rope of a specific length, while another person holds the other end of the rope. The second person circles the first and uses a wooden plank to bend the grain stalks until all the grain in that circle lies flat against the ground. Then they both move to make other circles. The result is often very beautiful, especially when seen from the air. Along with the image below, Use your knowledge of the unit circle and radian measure of angles to answer the following questions. [Note: When the questions ask you to consider circles and their angle in relation to the main circle, the question is referring to the location of the center of each circle.]
a. Consider circles 1 through 6. If these circles are equally spaced around the main circle, and circle 1 is at 0°, what is the direction (in degrees) of each of these circles in relation to the main circle?
b. Consider circles 7 through 12. If circle 7 is at 45°, what is the radian measure of each of these circles in relation to the main circle? Explain how you know these values.
c. If the center of circle 3 is 100 feet away from the main circle, what are the coordinates of the center of circle 3 (the origin is at the center of the main circle)? Use these coordinates to prove that the distance from the centers of circle 3 and the main circle are 100 feet apart.
d. After creating the design, the designers want to inspect their work. They start at 0° and walk all the way around the design almost two times and stop at circle 12. How many radians did they cover during their inspection?
e. Consider circles 5 and 6. In relation to the main circles, do the center points of circles 5 and 6 have even or odd symmetry? Why?

How to determine the valuesFrom the information given, we have that;
There are six major circles
Six minor circles
a. There are 6 circles at a point
Note that angles at a point sum up to 360 degrees
Now, let's divide their sum by the six parts
= [tex]\frac{360}{6}[/tex]
= [tex]60[/tex] degrees
Then, circle 1
= 0 × 60
= 0
Circle 2
= 1 × 60
= 60°
Circle 3
= 2 × 60
= 120°
Circle 4
= 3 × 60
= 180°
Circle 5
= 4 × 60
= 240°
Circle 6
= 5 × 60
= 300°
b. We have that each of these circles ( circle 7 - 12) radian measure is
= main circle - [tex]\frac{\pi }{12}[/tex]
The relative position or direction of circle 7 - 12 to their corresponding main circles ( 1 - 6) are all the same, we then have;
For circles 8
= 60° - 45°
= 15°
Circle 9
= 120° - 45°
= 75°
Circle 10
= 180° - 45°
= 155°
Circle 11
= 240° - 45°

Answers
The function with the greatest rate of change over the interval [0, 2] is: D. a.
How to determine function with the greatest rate of change?In Mathematics, the rate of change of a function over a given interval can be determined by calculating the slope of the straight line which connect its end points.
Mathematically, the slope of any straight line can be calculated by using this formula;
[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
For line a, we have:
Points (x, y) = (0, 1) and (2, 4)
Slope = (4 - 1)/(2 - 0)
Slope = 3/2 or 1.5.
For line b, we have:
Points (x, y) = (0, 0) and (2, 2)
Slope = (2 - 0)/(2 - 0)
Slope = 2/2 or 1.0.
For line c, we have:
Points (x, y) = (0, -1) and (2, 0)
Slope = (0 + 1)/(2 - 0)
Slope = 1/2 or 0.5.
For line d, we have:
Points (x, y) = (0, 0.5) and (2, 2.5)
Slope = (2.5 - 0.5)/(2 - 0)
Slope = 2/2 or 1.
In conclusion, we can logically deduce that "function a" has the greatest rate of change over the interval [0, 2].

If the sum of three numbers is 200, and the smallest number is 25, could the largest number be 75?
Answers
Answer:
No largest no could be 100
Step-by-step explanation:
Yes, the sum of the three numbers is 200, and the largest number can indeed be 75.
Let's assume the three numbers are:
Smallest number = 25
Middle number = x (unknown)
Largest number = 75
The sum of the three numbers is 200, so we can set up the equation:
25 + x + 75 = 200
Now, let's solve for x:
x = 200 - 25 - 75
x = 100
So, the middle number is 100.
Now, we can check if the largest number (75) is correct:
25 + 100 + 75 = 200

Mari works part time selling both hats and scarfs. One week she earns $114.00 by selling eight hats and 10 scarves. The following week she sold 12 hats and six scarves and earned $108.00. How much does she earn for each hat and scarf she sells?
Answers
Using a system of equations, it is found that she earns $5.5 for each hat and $7 for each scarf sold.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Variable x: Cost of a hat.Variable y: Cost of a scarf.One week she earns $114.00 by selling eight hats and 10 scarves, hence:
8x + 10y = 114.
The following week she sold 12 hats and six scarves and earned $108.00, hence:
12x + 6y = 108
Simplifying by 6:
2x + y = 18
y = 18 - 2x.
Replacing in the first equation:
8x + 10y = 114.
8x + 10(18 - 2x) = 114
12x = 66
x = 66/12

Answers
Answer:
28, 4 or 4, 28 (order doesn't matter, both are true answers)
Step-by-step explanation:
l + w = 32
l*w = 112
l = 112/w
112/w + w = 32
w = 28 or 4
l = 28 or 4
Answer:
4,28
Step-by-step explanation:
So let's look at the sentence to take any necessary information out. It says the length of a rectangle plus it's width is 32. Since we do not know what the length and width are, let's just represent them as L (length) and W (width). Using this information we get the equation: [tex]L + W = 32[/tex] and since we're given the area of the rectangle, we can also define another equation which is: [tex]LW = 112[/tex] since the length * width = area.
So now all we have is a systems of equations. We can solve for L or W in the area equation and plug it into the addition equation. We can also solve for L or W in the addition equation and then plug it into the area equation, either should work, but in this example I'll solve for L in the addition equation:
Original Equation:
[tex]L + W = 32[/tex]
Subtract 32 from both sides
[tex]L = 32-W[/tex]
Now let's use this definition of L to plug into the second equation:
[tex]LW = 112 \implies (32-W)W = 112[/tex]
Distribute the W
[tex]-W^2+32W=112[/tex]
Now if you notice, we simply have a quadratic equation and we can subtract 112 from both sides and then use the quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Subtract 112 from both sides
[tex]-W^2+32W-112=0[/tex]
Use quadratic formula
[tex]W = \frac{-32\pm\sqrt{32^2-4(-1)(-112)}}{2(-1)}[/tex]
Simplify stuff in radical
[tex]W = \frac{-32\pm\sqrt{576}}{-2}[/tex]
Calculate the square root
[tex]W=\frac{-32\pm24}{-2}[/tex]
Use positive sign:
[tex]W=\frac{-32+24}{-2}[/tex]
Simplify numerator
[tex]W = \frac{-8}{-2}[/tex]
Simplify fraction
[tex]W=4[/tex]
Take negative sign
[tex]W = \frac{-32-24}{-2}[/tex]
Simplify numerator
[tex]W=\frac{-56}{-2}[/tex]
W = [tex]28[/tex]
So we have two solutions, and the reason for this is because had we solved for W in the original equation and substituted that into here, there would be no different, it's not bound by some variable name. So these are actually the two sides of the rectangles

How many different 2 digit numbers are there with the following property: the tenth digit is greater that the units digit?
Answers
Answer:
45 numbers
Step-by-step explanation:
The 10-digit numbers are from 10-99. We can manually analyze each tenth digit and see if we can find a pattern from it. First, 10-19 ~ 10 is the only number in the sequence where the tenth digit is greater than the unit digit (because 1 > 0). In every other case, 1 is less than or equal to the unit digit.
Next, 20-29 ~ 20 and 21 are the two numbers where the tenth digit is greater than the unit digit
30-39 ~ 30, 31, 32 follow the property
40-49 ~ 40, 41, 42, 43 follow the property
We can keep going, but we can see that there is a pattern. The number of numbers that correspond with the property for each set of 10 numbers is equal to the value of the tenth digit. We see that for the 40s, there are 4 numbers. For the 20s, on the other hand, there are 2 numbers. This pattern carries through:
50-59 ~ 5 numbers, 60-69 ~ 6 numbers, 70-79 ~ 7 numbers, 80-89 ~ 8 numbers, 90-99 ~ 9 numbers
We need to find how many 2-digit numbers total follow the property. We can just add our results together to get our answer:

1. The zeros are at x = 0 and x = –10
2. The zeros are at x = 3 and x = 4
Step-by-step explanation:
1. f(x) = x (x + 10)
Multiplying any number by 0 = 0,
so f(x) = 0 when...
• x = 0
or
• x + 10 = 0 (if you subtract 10 from both sides, you get x = –10)
2. f(x) = x (x - 3) – 4 (x - 3)
Use distributive property to expand
x² – 3x – 4x + 12
Combine like terms
x² – 7x + 12
Factor
(x – 3) (x – 4)
(You could have also just noticed in the original function that both x and –4 were multiplied by (x – 3) and factored then.)
So f(x) = 0 when...
• x – 3 = 0 (add 3 to both sides to get x = 3)
or
• x – 4 = 0 (add 4 to both sides to get x = 4)

Which statements can be concluded from the diagram and used to prove that the triangles are similar by the SAS similarity theorem?
StartFraction R S Over V U EndFraction = StartFraction S T Over U T EndFraction and angle S is-congruent-to angle U
StartFraction R S Over V U EndFraction = StartFraction S T Over U T EndFraction = StartFraction R T Over V T EndFraction
StartFraction R S Over V U EndFraction = StartFraction T U Over T S EndFraction and angle S is-congruent-to angle U
StartFraction R S Over V U EndFraction = StartFraction T U Over T S EndFraction = StartFraction R T Over V T EndFraction
Answers
The statement that can be concluded from the triangle is A. RS/VU=ST/UT and ∠S≅∠U.
How to illustrate the information?The Side-Angle-Side Similarity Theorem states that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar.
In this problem the included angle is ∠S≅∠U, therefore side RS must be proportional to side VU and side ST must be proportional to side UT
Hence, RS/VU=ST/UT.

Answers
The ordered pairs (5 , -2) , (3 , 1) , (4 , 2) are in the set of the solution (Option C)
What is an ordered pair?An ordered pair is a composite of the x coordinate (abscissa) and the y coordinate (ordinate), with two values expressed between parenthesis in a predetermined order.
It aids visual comprehension by locating a point on the Cartesian plane.
How do we arrive at the solution?The first line has negative slope and passing through points (0 , 0) and (4 , -2)
That is y > (-1/2)x
The second line has positive slope and passing through points (-2 , 0) and (2 , 2)
That is: y < (1/2)x + 1.
- Refer to the accompanying diagram to discover the common component of the solutions.
- The inequity is shown by the red shading.
- The inequity is shown by the blue shading.
- The two-colored shaded area reflects the common solutions to the two inequalities.
- Let's discover the ordered pairs in the system of linear inequalities' solution set.
- Points (-4, 2), (-3, 1), (4, -3) define the common shaded area.

the operation:
[tex]2*10^1 - 4*10^0 = 20 - 4 = 16[/tex]
Gives a square number.
How to get a perfect square?
A perfect square is the product of a number and itself.
As you can see in the example, 16 is a square number. Then let's try to get 16.
To get 16 we can use the difference:
20 - 4
So the first therm needs to be equal to 20, and the second equal to 4.
To write 20 in scientific notation we have:
[tex]2*10^1[/tex]
To write 4 in in scientific notation:
[tex]4*10^0[/tex]
Then the operation:
[tex]2*10^1 - 4*10^0 = 20 - 4 = 16[/tex]
Gives a square number.

Answers
Imagine your square has an area of 64,
That means it’s sides are 8 x 8
So only rectangles that are 8inches x 8 inches or less will fit. A and C have these dimensions, they will fit. The other two will not. See my attachment, the green rectangle must fit inside the 8 x 8 square.

The next step Javier needs to take in order to evaluate the expression is to simplify it to it's lowest term. Details below
Data obtained from the questionExpression = 2a³ - 1Evaluation =?How to evaluate the expressionFrom the question given, we were told that Javier submitted 2 for a
Thus, the new expression becomes
2 × 2³ - 1
Recall
Aⁿ × Aᵐ = Aⁿ⁺ᵐ
Thus,
2 × 2³ = 2¹⁺³ = 2⁴
Therefore,
2 × 2³ - 1 = 2⁴ - 1
But
2⁴ = 16
Thus,
2⁴ - 1 = 16 - 1
2⁴ - 1 = 15
