Answer:

Step-by-step explanation:

The cost of the area of the deck is fixed, because the area is fixed. It will be ...

  ($12/ft²)×(100 ft²) = $1200

__

The cost of the railing is proportional to its length, so it will be minimized by minimizing the length of the railing. If the length of it is x feet parallel to the house, then the length of it perpendicular to the house (for a deck area of 100 ft²) is 100/x.

The total length of the railing is ...

  r = 2(100/x) + x

We can minimize this by setting its derivative with respect to x equal to zero:

  dr/dx = -200/x² +1 = 0

Multiplying by x² and adding 200, we get ...

  x² = 200

  x = √200 ≈ 14.142

So, the minimum railing cost will be had when the deck is 14.142 ft by 7.071 ft. That railing cost is about ...

  $9 × (200/√200 +√200) ≈ $254.56

__

We might imagine that dimensions near these values would have almost the same cost. Here are some other possibilities:

__

Then the total cost for a couple of possible deck sizes will be $1200 plus the railing cost, or ...

Step-by-step explanation:

Let AC be the length of original line segment and point B divides it into two segments such that AB is longer and BC is smaller segment.

[tex]AB+BC=AC=15[/tex]

We can describe the golden ratio as:  

[tex]\frac{AB}{BC}=\frac{AC}{AB}=1.618[/tex]

[tex]\frac{AC}{AB}=1.618[/tex]

[tex]\frac{15}{AB}=1.618[/tex]

[tex]\frac{15}{1.618}=AB[/tex]

[tex]9.270704=AB[/tex]

[tex]AB=9.271[/tex]

We can verify our answer as:

[tex]AB+BC=15[/tex]

[tex]9.271+BC=15[/tex]

[tex]9.271-9.271+BC=15-9.271[/tex]

[tex]BC=5.729[/tex]

[tex]\frac{AB}{BC}=1.618[/tex]

[tex]\frac{9.271}{5.729}=1.618[/tex]

[tex]1.618=1.618[/tex]

Hence proved.

Therefore, the length of the longer side would be 9.271 inches.

There are a total of 8 letters in student, with 6 different letters ( there are 2 s's and 2 t's).

First find the number of arrangements that can be made using 8 letters.

This is 8! which is:

Now there are 2 s's and 2 t's find the number of arrangements of those:

S = 2! = 2 x 1 = 2

T = 2! = 2 x 1 = 2

Now divide the total combinations by the product of the s and t's:

Answer:

Given the equation 8 + 3y = 2·(x+5)

slope=2/3

y- intercept= (0, 2/3) or y= 2/3.

x-intercept=  (-1, 0) or x = -1.

Step-by-step explanation:

Given 8 + 3y = 2·(x+5) ⇒ 8 + 3y = 2x + 10 ⇒ 3y = 2x + 10 -8 ⇒ 3y = 2x + 2

⇒ y = (2/3)x + 2/3.

Here slope = 2/3 and y-intercept = 2/3.

To find x-intercept, we have to calculate the value of "x" when y =0.

⇒ 0 = (2/3)x + 2/3 ⇒ 0 - 2/3 = (2/3)x ⇒ -2/3 = (2/3)x ⇒ (-2/3)/(2/3)= x

⇒ x =-1.

Answer:

  5 meters

Step-by-step explanation:

The height of the lamppost above the person is twice the height of the person, so the distance between the lamppost and person is twice the length of the person's shadow. (A diagram can help you see this.)

The person's shadow is (10 m)/2 = 5 m long.

___

Check

The tip of the shadow is 15 m from the lamppost, 2.5 times the height of the lamp. The tip of the shadow is also 5 m from the person, 2.5 times the height of the person. The triangles involved are similar.

Final answer:

To find the length of the person's shadow, we use the properties of similar triangles defined by the person and the lamppost. By setting up a proportion between the person's and the lamppost's height to their respective shadow lengths and solving, we find the person's shadow is 5 meters long.

Explanation:

To solve the problem of determining the length of the shadow cast by the person standing 10 meters from the lamppost at night, we can use the concept of similar triangles.

Since the light source (lamppost) is above ground level, the triangle formed by the lamppost, the end of the shadow, and the top of the person's head is similar to the triangle formed by the person, their shadow, and the ground. Using the properties of similar triangles, the ratios of corresponding sides are equal.

Let's denote the length of the person's shadow as s. The triangles' corresponding sides' ratios would be:

Setting up the proportion, we have:

2 / s = 6 / (10 + s)

By cross-multiplying and solving for s, we get:

2(10 + s) = 6s

20 + 2s = 6s

4s = 20

s = 5

Hence, the length of the person's shadow is 5 meters.

Answer:

128 posibilities

Step-by-step explanation:

We have 7 colleges (A,B,C,...,H) which form a set with seven elements.

What you are asking is the number of elements (or cardinality) of the set that contains all possible sets formed by those 7 elements (or the "power set").

It is known that if n is the number of elements of a given set X, then the cardinality of the power set is [tex]2^n[/tex].

Therefore, there are [tex]2^7[/tex] or 128 possibilities (or elements) for the set of colleges that he applies to.

Final answer:

The number of possible combinations of colleges that Jose can apply to from 7 options is 128. This includes the possibility of not applying to any college as well.

Explanation:

The question asks how many different combinations of colleges Jose may apply to given 7 different options.

This is a problem related to the field of combinatorics in mathematics, specifically the concept of the power set, where each college can either be chosen or not, resulting in 2⁷ possible combinations.

Since he can like none, some, or all colleges, we include the possibility of an empty set, leading to a total of 2⁷ = 128 possibilities.

In each case, Jose has two options for every college - to apply (like) or not to apply (dislike).

Therefore, the number of combinations is calculated by raising 2 (the number of options for each item) to the power of 7 (the number of items).

Answer:

Step-by-step explanation:

Recall that for a function f(x) and for a constant k

f(x+k) represents a horizontal translation for the function f(x) by k units in the negative-x direction.

Hence f(x+k) is simply the graph of f(x) that has been moved left (negative x direction) by k units.

From the graph, we can see that g(x) = f(x+k) is simply the graph of f(x) that has been moved 4 units in the negative x-direction.

hence K is simply 4 units.

Answer:D

THE POPULATION OF SPECIES A IS DECREASING. AND IT HAD THE SMALLER INITIAL POPULATION

The statement that correctly compares the given functions is - 'The population of species A is decreasing, and it had the smaller initial population.'

The correct answer is an option (D)

"A function of the form [tex]f(x)=b^x[/tex] where b is constant."

" [tex]f(x) = a (1 + r)^x[/tex]

where a is the initial value

r is the growth rate

x is time"

For given question,

We have been given a exponential function [tex]f(x) = 1400(0.70)^x[/tex]

This function represents the population of species A, x years from today.

The population of species B is modeled by function g, which has an initial value of 1,600 and increases by 20% per year.

a = 1600

r = 20%

 = 0.2  

Using the exponential growth formula the exponential function that represents the population of species B would be,

[tex]g(x) = 1600 (1 + 0.2)^x\\\\g(x)=1600(1.02)^x[/tex]

We know that, if the factor b ([tex]f(x)=a\bold{b}^x[/tex]) is greater than 1 then the exponential function represents the growth and if b < 1 then the exponential function represents the decay of population.

From functions f(x) and g(x) we can observe that, the population of species A is decreasing, and it had the smaller initial population.

So, the correct answer is an option (D)

Answer:

Step-by-step explanation:

We notice that the multiplier of the squared term in f(x) is 0.5; in g(x), it is -2, so is a factor of -4 times that in f(x).

If we scale f(x) by a factor of -4, we get ...

  -4f(x) = -2(x -2)² -12

In order for the squared quantity to be x+3, we have to add 5 to the value that is squared in f(x). That is, x -2 must become x +3. We have to replace x with (x+5) to do that, so ...

  (x+5) -2 = x +3

The replacement of x with x+5 amounts to a translation of 5 units to the left.

We note that the added constant after our scaling changes from +3 to -12. Instead, we want it to be -1, so we must add 11 to the scaled function. That translates it upward by 11 units.

The attached graph shows the scaled and translated function g(x):

The Chord Intersection Theorem:

If 2 chords of a circle are AB and CD and they intersect at E, then

AE * EB = CE * ED.

Problem.

Two Chords AB and CD intersect  at E.  If AE =  2cm , EB = 4 and CE = 2.5 cm, find the length of ED.

By the above theorem : 2 * 4 = 2.5 * ED

ED = (2 * 4) / 2.5

The measure of ∠XYZ is 35°.

Secants theorem states that the angle formed by the two secants which intersect inside the circle is half the sum of the intercepted arcs.

Here is the problem of chords that we would use the secants theorem

Circle A is shown. Secant W Y intersects tangent Z Y at point Y outside of the circle. Secant W Y intersects circle A at point X. Arc X Z is 110° degrees and arc W Z is 180° degrees. In the diagram of circle A, what is the measure of ∠XYZ?

We want to determine the angle ∠XYZ in the image attached.

To solve that, we will use the formula in the theorem for angles formed by secants or tangents. Thus;

According to Secants theorem,

∠XYZ = ½(arc WZ - arc XZ)

Given, arc WZ = 180° and arc XZ = 110°

Thus;

∠XYZ = ½(180 - 110)

∠XYZ = ½(70)

∠XYZ = 35°

Hence, the measure of ∠XYZ is 35°.

Bobby's economic profit for the day is $0.60, calculated by subtracting his total cost of $3.40 from his total revenue of $4.00. Here option A is correct.

To calculate Bobby's economic profits, we first need to understand the concept of economic profit.

Economic profit is calculated as total revenue minus total cost. Total revenue (TR) is the total amount of money earned from selling a product, which is calculated by multiplying the quantity sold (Q) by the price per unit (P). Total cost (TC) is the total expense incurred in producing a product.

In this case, we have the following information:

Bobby sells 20 glasses of lemonade at $0.20 per cup, so his total revenue is:

TR = 20 cups * $0.20/cup = $4.00

Bobby's average total cost is $0.17 per cup. Since he sold 20 cups, his total cost is:

TC = 20 cups * $0.17/cup = $3.40

Now, we can calculate Bobby's economic profit:

Economic Profit (π) = Total Revenue (TR) - Total Cost (TC)

= $4.00 - $3.40

= $0.60

So, Bobby's economic profit for the day is $0.60.

Answer:

The answer to your question is: height = 99.41 feet.

Step-by-step explanation:

Data

distance = 96 feet away from a building

angle = 46

height = ?

Process

Here, we have a right triangle, we know the angle and the adjacent leg, so let's use the tangent to find the height.

tan Ф = opposite leg / adjacent leg

opposite leg = height = adjacent leg x tan Ф

height = 96 x tan 46

height = 96 x 1.035

height = 99.41 feet.

The height of the building is approximately 77.55 feet.

To find the height of the building, we can use trigonometry, specifically the tangent function, which relates the angle of elevation to the opposite side (the height of the building) and the adjacent side (the distance from the point of observation to the base of the building).

Given:

- The distance from the point of observation to the base of the building is 96 feet.

- The angle of elevation to the top of the building is 46 degrees.

Using the tangent function:

[tex]\[ \tan(\theta) = \frac{\text{opposite}}{\text{adjacent}} \][/tex]

[tex]\[ \tan(46^\circ) = \frac{h}{96} \][/tex]

To find the height [tex]\( h \)[/tex], we solve for[tex]\( h \)[/tex]:

[tex]\[ h = 96 \times \tan(46^\circ) \][/tex]

Using a calculator to find the tangent of 46 degrees and multiplying by 96, we get:

[tex]\[ h \approx 96 \times \tan(46^\circ) \approx 96 \times 0.9919 \approx 77.55 \text{ feet} \][/tex]

The maximum volume of such a box is determined by forming an equation that represents the condition about the width of the box and the perimeter of one of its nonsquare sides, then finding the maximum value of the volume function obtained by differentiating the function and setting it equal to zero.

The subject of this question is mathematics related to box dimensions, more specifically the geometry dealing with volume of a box. The box in question has a square base, which means the length and width are the same, let's call this x. Because the box is wider than it is tall, we know it's height, let's call it h, is less than x.

According to the question, the width of the box and the perimeter of one of the nonsquare sides of the box sum to no more than 117 inches. The perimeter of a nonsquare side (a rectangle) is given by 2(x+h), and if we add x (the width of the box) to this, we get x + 2(x+h) which must be less than or equal to 117. Simplifying gives 3x + 2h <= 117

We are interested in the volume of the box which can be determined by multiplying the length, width, and height (V = x*x*h). This can be simplified to V = x^2 * h. To get the maximum volume, we should make h as large as possible. Substituting 3x into the original inequality for h (since 3x <= 117), we get h <= 117 - 3x. Thus, the volume V becomes V = x^2 * (117 - 3x).

To find the maximum volume, we take the derivative of the volume function (V = x^2 * (117 - 3x)) with respect to x and set it equal to zero. This will give us the value of x for which the volume is maximum. Once we have the value of x, we substitute it back into the volume function to get the maximum volume.

The maximum volume for such a box is 152,882.5 cubic inches

We have a box with a square base, where the width w is greater than the height h. The constraint given is that the width of the box plus the perimeter of one of the non-square sides cannot exceed 117 inches.

The perimeter of one of the non-square sides is 2h + 2d, where d is the depth. Therefore, the constraint equation becomes:

[tex]\[ w + 2h + 2d \leq 117 \][/tex]

Since the base is square, w = h. Let's denote this common value as s. So, the constraint equation simplifies to:

[tex]\[ 2s + 2d \leq 117 \][/tex]

Now, we need to express the volume of the box in terms of s and d:

[tex]\[ V = s^2d \][/tex]

We want to maximize V subject to the constraint [tex]\(2s + 2d \leq 117\).[/tex]

To proceed, let's solve the constraint equation for d:

[tex]\[ d \leq \frac{117 - 2s}{2} \][/tex]

Since d must be greater than zero, we have:

[tex]\[ 0 < d \leq \frac{117 - 2s}{2} \][/tex]

Now, we substitute [tex]\(d = \frac{117 - 2s}{2}\)[/tex] into the volume equation:

[tex]\[ V(s) = s^2 \left( \frac{117 - 2s}{2} \right) \]\[ V(s) = \frac{1}{2}s^2(117 - 2s) \][/tex]

To find the maximum volume, we'll take the derivative of V(s) with respect to s, set it equal to zero to find critical points, and then check for maximum points.

[tex]\[ V'(s) = \frac{1}{2}(234s - 6s^2) \]\\Setting \(V'(s)\) equal to zero:\[ \frac{1}{2}(234s - 6s^2) = 0 \]\[ 234s - 6s^2 = 0 \]\[ 6s(39 - s) = 0 \][/tex]

This gives us two critical points: s = 0 and s = 39. Since s represents the width of the box, we discard s = 0 as it doesn't make physical sense.

Now, we need to test s = 39 to see if it corresponds to a maximum or minimum. Since the second derivative is negative, s = 39 corresponds to a maximum.

So, the maximum volume occurs when s = 39 inches.

Substitute s = 39 into the constraint equation to find d:

[tex]\[ 2(39) + 2d = 117 \]\[ 78 + 2d = 117 \]\[ 2d = 117 - 78 \]\[ 2d = 39 \]\[ d = \frac{39}{2} \]\[ d = 19.5 \][/tex]

Therefore, the maximum volume of the box is achieved when the width and height are both 39 inches, and the depth is 19.5 inches. Let's calculate the maximum volume:

[tex]\[ V_{\text{max}} = (39)^2 \times 19.5 \]\[ V_{\text{max}} = 152,882.5 \, \text{cubic inches} \][/tex]

So, the maximum volume for such a box is 152,882.5 cubic inches.

Answer:

The value of x is 7.

Step-by-step explanation:

Consider the provided figure.

It is given that both the pentagons are similar.

That means the ratio of the sides will be same and we need to find the value of x.

[tex]\frac{NM}{TS}=\frac{ML}{SR}[/tex]

Substitute the respective values in the above formula.

[tex]\frac{4}{5.6}=\frac{5}{x}[/tex]

[tex]4x=5\times 5.6[/tex]

[tex]x=\frac{28}{4}[/tex]

[tex]x=7[/tex]

Hence, the value of x is 7.
