Answers
The length of the shadow when the sun altitude is 60 degrees is 8.7 feet.
How to find the side of a right triangle?The clock tower is 15 feet tall. The length of the shadow when the sun is at an altitude of 60 degrees can be calculated as follows:
This situation forms a right angle triangle.
Hence, using trigonometric ratios,
tan 60 = opposite / adjacent
where
opposite side = 15 feet
adjacent side = x
tan 60 = 15 / x
cross multiply
x tan 60° = 15
divide both sides by tan 60
x = 15 / tan 60
x = 15 / 1.73205080757
x = 8.65800865801
x = 8.7 feet
Therefore,
length of shadow = 8.7 feet.

STEP-BY-STEP EXPLANATION:
We have that the population function has the following form:
\(y=A\cdot e^{kt}\)Where y is the population after t time, A is the initial population and k is the growth constant.
Therefore, for each case, we calculate the value of k:
(a)
t = 4
y = 1375000
A = 1309000
Solving for k:
\(\begin{gathered} 1375000=1309000\cdot\: e^{k\cdot4} \\ e^{4k}=\frac{1375000}{1309000} \\ 4k=\ln \: \mleft(\frac{1375000}{1309000}\mright) \\ k=\frac{\ln\mleft(\frac{1375000}{1309000}\mright)}{4} \\ k=0.01229\cong0.0123\rightarrow1.23\text{\%} \end{gathered}\)(b)

\(undefined\)North Dakota has 465 campgrounds over 12 counties while West Virginia has 711 campgrounds. If North Dakota was proportional to West Virginia in the number of campgrounds to counties, how many counties would West Virginia be expected to have? Round to the nearest whole number.
Answers
Number of countries would west Virginia be expected to have is 18 countries
The number of campgrounds that North Dakota has = 465 campgrounds
The number of countries = 12 countries
The number of campgrounds that West Virginia has = 711 campgrounds
Given that the North Dakota was proportional to West Virginia in the number of campgrounds to counties.
The proportion will be
465 / 12 = 711 / x
Divide the terms
38.75 = 711 / x
x = 711 / 38.75
Divide the terms
x = 18.4
x ≈ 18 countries
Hence, number of countries would west Virginia be expected to have is 18 countries

A card is drawn randomly from a standard deck of cards. You win $5 if the card is adiamond or a king. What is the probability that you will win 5 dollars?
Answers
EXPLANATION
Let name event A as the event of drawing a Diamond and let us name event B as the event of drawing an King.
Now, we are required to find P(A union B)
We know that P(A union B) = P(A) + P(B) - P(A intersection B) … (i)
Let's suppose there are 52 cards in a standard deck.
A standard deck of cards has 13 diamonds and 4 kings
We have P(A) = 13/52 = 1/4, P(B) = 4/52 = 1/13
A intersection B denotes the case of the King of Diamonds whose probability = 1/52
Now plugging in these values to equation (i) and simplifying, we obtain the required probability as P(A union B) = 1/4 + 1/13 - 1/52 = 4/13
The probability is 4/13 or 0.307 or 30.7%
what is the property of 3x(5x7)=(3x5)7
Answers
The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.
In the equation you provided: 3x(5x7) = (3x5)7
The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

f(x)=
Answers
The formula for the linear function in the graph is f(x) = -2x + 4.
What is graph?The graph is a data structure that is used to represent relationships between objects. It is composed of nodes (or vertices) that are connected by edges (or lines). Graphs can be used to represent many types of data, such as networks of people, roads, and even abstract concepts like language. Graphs are used in a variety of fields, such as computer science, mathematics, and sociology. They allow for efficient storage and retrieval of data, as well as efficient traversal of the data.
The graph shown below is a linear graph with a slope of -2 and a y-intercept of 4.
To find the formula for the linear function, we can use the slope-intercept form, which is y = mx + b. In this equation, m is the slope of the line and b is the y-intercept.
Therefore, the formula for the linear function in the graph is f(x) = -2x + 4.

How do I find the possible degree(s) of a function from the graph alone?
Answers
Answer:
To determine the possible degree(s) of a function from the graph alone, you need to examine the behavior of the graph at the extremes (far left and far right) and consider the number of turning points or changes in direction. Here's a step-by-step approach:
Look at the far left side of the graph: Determine the behavior of the graph as it approaches negative infinity. Does the graph approach a specific value, such as a horizontal line (asymptote) or the x-axis? If the graph approaches a horizontal line, it suggests a polynomial function of even degree. If the graph approaches the x-axis, it indicates a polynomial function of odd degree or possibly a function with a root of multiplicity greater than one.
Look at the far right side of the graph: Determine the behavior of the graph as it approaches positive infinity. Similar to step 1, observe if the graph approaches a specific value or a horizontal line. The behavior at the far right side should be consistent with the behavior at the far left side. This can help you identify if the function is even or odd degree.
Examine the number of turning points or changes in direction: Count the number of times the graph changes direction. These points are where the slope of the graph changes from positive to negative or vice versa. The number of turning points can provide an indication of the degree of the polynomial. For example, if there are two turning points, it suggests a polynomial function of degree 3.
Remember that this method provides potential degrees, but it may not definitively determine the exact degree of the function. Additional information or analysis might be required for a more accurate determination.

Which statement is not always true?
Answers
Answer:
\((c)\ \tan B = \sin A\)
Step-by-step explanation:
Given
\(\angle A + \angle B = 90\) --- Complement angles
See attachment for complete question
Required
Which is not always true
To do this, we simply test each option
\((a)\ \sin A = \cos B\)
The above is always true, if A and B are complements.
Examples are:
\(\sin(40) = \cos(50)\)
\(\sin(90) = \cos(0)\)
etc
\((b)\ \sec A = \csc B\)
The above is always true, if A and B are complements.
The expression can be further simplified as:
\(\frac{1}{\cos A} = \frac{1}{\sin B}\)
Cross Multiply
\(\sin B = \cos A\)
This is literally the same as (a)
\((c)\ \tan B = \sin A\)
The above is not always true, if A and B are complements.
The expression can be further simplified as:
\(\frac{\sin B}{\cos B} = \sin A\)
Cross multiply
\(\sin B = \sin A * \cos B\)
If A and B are complements. then
\(\sin A = \cos B\)
So, we have:
\(\sin B = \sin A * \sin A\)
\(\sin B = \sin^2 A\)
The above expression is not true, for values of A and B
\((d) \cot B = \tan A\)
The above is always true, if A and B are complements.
An example is:
\(\cot (55) = \tan (25) = 0.7002\)
etc.

The Ozzie Chocolate Company is preparing to offer a new product in its candy offerings, the Minty Dark Chocolate Bite bar. Material costs per new candy bar are
$0.25 for chocolate, $0.02 for sugar, and $0.03 for mint flavoring. Labor costs of the new product are approximately $0.15 per bar. Adding a production line devoted to the new candy will cost $250,000 per year.
(a) If the sales price is $1.40 per candy bar, how many must the company make per year in order to break even? Assume that each bar made is sold at full price.
(b) What is the company's profit or loss if they make and sell 270,000 candy bars at the $1.40 price in the first year?
(c) About 20% of the food consumed in the U.S. is imported. Production in many industries has been offshored. What ethical issues do companies face when presented with the decision to move operations?
Answers
Answer:
a) 263,158
b) $164,500
c) Ethical issues companies face when deciding to move operations: job loss for employees, poor working conditions and exploitation of workers, negative environmental impact,...
Step-by-step explanation:
a)
Total cost = (0.25 + 0.02 + 0.03 + 0.15) x + 250,000
Total revenue = 1.40x
Setting the two equations equal to each other and solving for x, we get:
(0.45)x + 250,000 = 1.40x
0.95x = 250,000
x ≈ 263,158
b)
If the company sells 270,000 candy bars at $1.40 each, the total revenue generated is:
270,000 * $1.40 = $378,000
The total cost of producing 270,000 candy bars is:
(0.25 + 0.02 + 0.03 + 0.15) * 270,000 + $250,000 = $213,500
Therefore, the company's profit is:
$378,000 - $213,500 = $164,500
c)
Ethical issues companies face when presented with the decision to move operations: job loss for employees, poor working conditions and exploitation of workers, negative environmental impact,...
