Tyler is building a fish tank in the shape of a sphere that has a diameter of 18 inches. Based on Tyler's research, it is recommended to have no more than 1 goldfish for every 693 cubic inches of water. How many goldfish should Tyler buy for his fish tank?

The unclear query may pertain to post-high school plans or high school curriculum. The majority of high school graduates in the US tend to pursue higher education immediately after graduating. Similarly, the number of English courses taken by male and female high school students is typically equivalent.

The question is somewhat ambiguous as it does not specify a clear query related to students from grade 11 and 12. However, deriving from the provided information, perhaps the student is seeking to understand statistics related to post-high school plans, or is interested in curriculum reviews, or the number of English courses taken by students.

For instance, focusing on life after high school, we know that a significant majority of high school graduates in the US (~69%) begin their college journey immediately following their graduation. This indicates that the orientation towards pursuing higher education is prevalent among recent high school graduates.

On the other hand, if interest lies in the English curriculum, an analysis reveals that the mean number of English courses taken by both male and female high school students over two years generally align with each other.

Answer:

The area of the house is approximately 309.54 feet²

Step-by-step explanation:

* Lets describe the figure

- It has a quarter circle with radius = the width of the rectangle

- It has a rectangle with length = 26 - the length of the radius, and

 width 10 feet

- It has a triangle with base equal the length of the rectangle and

 height 8 feet

- It has a trapezoid, the length of its two parallel bases are 2 , 5 and

 height 2 feet

* Lets revise the area of all the shape above

- Area the quarter circle = 1/4 π r²

- Area of the rectangle = length × width

- Area of the triangle = 1/2 × base × height

- Area of the trapezoid = 1/2( the sum of the parallel bases) × height

* Now lets solve the problem

# Area of the quarter circle

∵ The radius of the circle = the width of the rectangle

∵ The width of the rectangle = 10 feet

∴ The radius of the circle = 10 feet

∵ The area of the quarter circle = 1/4 π r²

∴ Its area = 1/4 π (10)² = 25π feet²

# Area of the rectangle

∵ The length of the rectangle = 26 - the length of the radius

∵ the length of the radius = 10 feet

∴ The length of the rectangle = 26 - 10 = 16 feet

∵ The width of the rectangle = 10 feet

∵ The area of the rectangle = length × width

∴ Its area = 16 × 10 = 160 feet²

# Area of the triangle

∵ The base = the length of the rectangle

∵ The length of the rectangle = 16 feet

∴ The base = 16 feet

∵ The height = 8 feet

∵ The area of the triangle = 1/2 × base × height

∴ Its area = 1/2 × 16 × 8 = 64 feet²

# Area of the trapezoid

∵ The length of its two parallel bases are 2 feet , 5 feet

∵ The height = 2 feet

∵ The area = 1/2( the sum of the parallel bases) × height

∴ Its area = 1/2 (2 + 5) × 2 = 7 feet²

- Lets add all of these areas to find the area of the house

∴ The area of the house = 25π + 160 + 64 + 7 = 309.5398 feet²

* The area of the house is approximately 309.54 feet²

ANSWER

The correct factorization is

[tex]p^{3} - 343q^{3} = (p - 7q)( {p}^{2} + 7pq + {49q}^{2} )[/tex]

EXPLANATION

The given expression is

[tex] {p}^{3} - 343 {q}^{3} [/tex]

We can write this as difference of cubes.

[tex]{p}^{3} - {7}^{3} {q}^{3} [/tex]

[tex]{p}^{3} - ( {7} {q})^{3} [/tex]

We can now factor using the difference of cube identity:

[tex] {x}^{3} - {y}^{3} = (x - y)( {x}^{2} + xy + {y}^{2} )[/tex]

We substitute x=p and y=7p to get:

[tex]{p}^{3} - ( {7} {q})^{3} = (p - 7q)( {p}^{2} + p \times 7q + ({7q})^{2} )[/tex]

[tex]{p}^{3} - ( {7} {q})^{3} = (p - 7q)( {p}^{2} + 7pq + {49q}^{2} )[/tex]

Final answer:

The polynomial p^3 - 343q^3 is factorized as (p - 7q)(p^2 + 7pq + 49q^2) using the difference of cubes formula.

Explanation:

The correct factorization of the polynomial p3 - 343q3 can be done using the difference of cubes formula, which is a3 - b3 = (a - b)(a2 + ab + b2). Comparing the given polynomial to the formula, we see that a corresponds to p and b corresponds to 7q since 343 is 7 to the power of 3. Therefore, the factorization would be (p - 7q)(p2 + 7pq + 49q2). Always check for the correct signs and coefficients when factoring polynomials, especially when dealing with differences and sums of cubes.

For this case we have a function of the form [tex]y = f (x)[/tex], where:

[tex]f (x) = - x ^ 2 + 1[/tex]

We must evaluate the function for [tex]x = -3[/tex]

Then we have to replace:

[tex]f (-3) = - (- 3) ^ 2 + 1\\f (-3) = - 9 + 1[/tex]

Different signs are subtracted and the sign of the major is placed:

[tex]f (-3) = - 8[/tex]

ANswer:

[tex]f (-3) = - 8[/tex]

Answer:

f(1) = 1

Step-by-step explanation:

A function can have only one value of y for a given value of x.

Thus, if f(1) = 5, we cannot have f(1) = 1.

We can have f(2) =1 and f(5) = 5, because these are values of y for different values of x,

The first diagram below is the graph of a function, because there is only value of y that corresponds to a given value of x.

The second diagram is not the graph of a function, because there are two values of y that correspond to a given value of x.

However, the top semicircle and the bottom semicircle separately are graphs of functions, because they each have only value of y that corresponds to a given value of x.

Final answer:

The statement that could not be true for a function f(x) where f(1) = 5 is any claim that f(x) takes a different value than 5 for any x within the domain [0, 20], where f(x) is described as a horizontal line. Therefore, if f(1) = 5, it must be true that f(x) = 5 for all x in [0, 20].

Explanation:

If f(x) is a function and f(1) = 5, then it indicates that when we input 1 into the function f, we get the output of 5. The question asks which statements could not be true based on this piece of information and additional details regarding the nature of function f. The provided information suggests that the graph of f(x) is horizontal for 0 ≤ x ≤ 20, which means the output value of f(x) is the same for any input value x within that domain.

Likewise, we can determine some possible characteristics of f(x) based on the nature of continuous functions. Adding a constant to f does not affect the derivative, so despite the value of f at x = 1 being 5, we cannot deduce the exact form of f but can infer its behavior around that point. It is essential to note that when a function is defined as a continuous horizontal line within a certain domain, its value is constant across that domain. As a result, if f(1) = 5 for the function f(x) = a horizontal line on the interval [0, 20], it implies that f(x) must be 5 for all x in that interval.

Therefore, any statement that implies the function has a different value than 5 for any x in [0, 20] cannot be true. For instance, if there were a claim that f(2) ≠ 5 or that f(x) is not defined for some x within the interval where it is supposed to be a horizontal line, such a statement would be false given the function's described behavior.

a LINEar function has well, the graph of a straight line, so this isn't that.

is it a relation? well, yes, because the y-value correlates with the x-value, so one depends or relates to the other.

is it a non-linear function?  well, a function has to pass the vertical line test, meaning if we draw vertical lines they must touch the graph only once on their way down.... and in this case it seems they do, so it is non-linear clearly, and it's also a function.

Answer:

A) No B) The relation f(8) C) x = 3

Step-by-step explanation:

A) In mathematics, a function is a relation between sets that associates to every element of a first set exactly one element of the second set. Typical examples are functions from integers to integers or from the real numbers to real numbers.

B) Lets name the upper table outputs "g(x)", so

[tex]g(8) = 8 \: \: and \: \: f(8) = 8 \times 8 - 5 = 64 - 5 = 59[/tex]

[tex]\: 59 > 8 \: \: therefore \: \: f(8) > g(8)[/tex]

C)

[tex]f(x) = 19 \: \: and \: \: f(x) = 8x - 5 \\ 8x - 5 = 19 \\ 8x = 19 + 5 \\ 8x = 24 \\ x = 24 \div 8 \\ x = 3[/tex]

That's a difference of three standard deviations or 3(1.9) = 5.7 minutes.

Answer: 5.7 min, third choice

We are given:

2x + 5 - 3x = 8(x + 1)

We can start with several things. First, we can combine the x terms on the left side of the equation, and apply the distributive property on the right side of the equation.

5 - x = 8x + 8

Now, we can add x to both sides, and subtract 8 from both sides to isolate the variable.

5 - x = 8x + 8

-8 + x  + x -8

We end up with:

9x = -3

By dividing both sides by 9, we get x = [tex]-\frac{1}{3}[/tex].

If you want to check your answer, just plug x in!

2([tex]-\frac{1}{3}[/tex]) + 5 - 3([tex]-\frac{1}{3}[/tex]) = 8([tex]-\frac{1}{3}[/tex] + 1)

[tex]-\frac{2}{3}[/tex] + 5 + 1 = [tex]-\frac{8}{3}[/tex] + 8

[tex]-\frac{2}{3}[/tex] + [tex]\frac{18}{3}[/tex] = [tex]-\frac{8}{3}[/tex] + [tex]\frac{24}{3}[/tex]

[tex]\frac{16}{3}[/tex] = [tex]\frac{16}{3}[/tex]

As you can see, [tex]\frac{16}{3}[/tex] = [tex]\frac{16}{3}[/tex] as a result of having x = [tex]-\frac{1}{3}[/tex].

First you must distribute the 8 to the numbers inside the parentheses

2x + 5 - 3x = 8 (x + 1)

2x + 5 - 3x = 8*x + 1*8

2x + 5 - 3x = 8x + 8

Now you must combine like terms (let's first start with the like terms on the left side). This means the numbers with the same variables must be combined...

-3x + 2x = -x

so...

-x + 5 = 8x + 8

Now you must combine like terms by combining -x with 8x. To do this first add 1x to both sides (what you do on one side you must do to the other). Since x is negative on the left side, addition (the opposite of subtraction/negative) will cancel it out (make it zero) from the left side and bring it over to the right side.

-x + x + 5 = 8x + x + 8

0 + 5 = 9x + 8

5 = 9x + 8

Now bring 8 to the left side by subtracting 8 to both sides (what you do on one side you must do to the other). Since 8 is being added on the right side, subtraction (the opposite of addition) will cancel it out (make it zero) from the right side and bring it over to the left side.

5 - 8 = 9x + 8 - 8

-3 = 9x

Next divide 9 to both sides to finish isolating x. Since 9 is being multiplied by x, division (the opposite of multiplication) will cancel 9 out (in this case it will make 9 one) from the right side and bring it over to the left side.

-3/9 = 9x/9

x = [tex]\frac{-1}{3}[/tex]

Law of Cosines

Angle A = 45°

Angle B = 51°

Angle C = 84°

Step-by-step explanation:

Law of sines is used when we are given

a) two angles and one side or

b) two sides and non-included angle

Law of cosines is used when we are given

a) three sides or

b) two sides and included angle

In the given question we are given three sides so, Law of Cosines will be used to solve the triangle.

Law of Cosines is:

[tex]a^2 = b^2 + c^2 -2bccos A\\b^2 = a^2 + c^2 -2accos B\\c^2 = a^2 + b^2 -2abcosC[/tex]

We will find the three angles A ,B and C of the triangle using above formula.

a= 10, b=11, c=14

Putting values and finding angle A

[tex]a^2 = b^2 + c^2 -2bccos A\\(10)^2 = (11)^2 + (14)^2 -2(11)(14)cosA\\100 = 121 + 196 -308cosA\\100 = 317 -308 cosA\\100-317 = -308cosA\\-217/-308  = cos A\\0.704 = cos A\\=> A = cos ^{-1}(0.704)\\A= 45[/tex]

Now finding angle B

[tex]b^2 = a^2 + c^2 -2ac cos B\\(11)^2 = (10)^2 + (14)^2 - 2(10)(14)cosB\\121 = 100+196 - 280cosB\\121 -296 = -280cosB\\-175/-280 = cosB\\0.625 = cosB\\=> B = cos^{-1} (0.625)\\B = 51[/tex]

Now finding angle C

[tex]c^2 = a^2 + b^2 -2abcosC\\(14)^2 =(10)^2 + (11)^2 -2(10)(11)cosC\\196 = 100+121 -220cosC\\196 -221 = -220cosC\\-25/-220 = cos C\\0.11 = cosC\\=> C = cos^{-1}(0.11)\\C= 84[/tex]

Step-by-step explanation:

The perpendicular bisector is positioned at the midpoint of AB at right angles.

We require to find the midpoint and slope m of AB

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = A(3, 8) and (x₂, y₂ ) = B(- 5, 6)

m = [tex]\frac{6-8}{-5-3}[/tex] = [tex]\frac{-2}{-8}[/tex] = [tex]\frac{1}{4}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{4} }[/tex] = - 4

mid point  = [0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]

Using the coordinates of A and B, then

midpoint AB = [0.5(3 - 5), 0.5(8 + 6) ] = (- 1, 7 )

Equation of perpendicular in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

with m = - 4

y = - 4x + c ← is the partial equation

To find c substitute (- 1, 7) into the partial equation

Using (- 1, 7), then

7 = 4 + c ⇒ c = 7 - 4 = 3

y = - 4x + 3 ← equation of perpendicular bisector

Notice that 10.5 is the amount of time in minutes that Samuel has run.

x represents the amount of additional time it will take to finish the race

33 represents the time limit in which you want to finish the race

The we solve the inequality

[tex]10.5 + x < 33[/tex]

Subtract 10.5 on both sides of the inequality

[tex]10.5 -10.5 + x < 33-10.5[/tex]

[tex]x < 33-10.5[/tex]

[tex]x < 22.5[/tex]
