Answer:

178.98 square feet

Step-by-step explanation:

Alright so we need to find two areas here and find the difference to find the area of the path.

The two shapes involved is a smaller circle inside a bigger circle.

Let's look at the smaller circle, the gardening area.

You are given is has a radius of 8 ft.

The area of a circle is [tex]\pi \cdot r^2[/tex] where r is the radius.

So the area of the smaller circle is [tex]\pi \cdot 8^2[/tex].

Now time to look at the bigger area (which will have some overlapping area with the smaller one which will subtract out to find the area of path).

The diameter of the smaller circle was (8+8)=16 feet.

What is the diameter of the bigger one.  The path is 3 ft wide so we have to add a 3 before the diameter of the smaller circle to another 3 after that diameter to get the diameter of the bigger circle.  So the diameter of the bigger circle is (3+16+3)=22 feet.  The radius is half the diameter so the radius is 22/2=11.

The area of the bigger circle is [tex]\pi \cdot 11^2[/tex].

The area of the path=

the area of bigger circle     -      the area of smaller circle=

[tex]\pi \cdot 11^2-\pi \cdot 8^2[/tex]

Type this into your calculator with 3.14 instead of the [tex]\pi[/tex] button.

178.98 square feet

The answer is:

[tex]PathArea=178.98ft^{2}[/tex]

To calculate the are of the path alone, we need to add the width of the path to the radius of the garden in order to know is radius, then, calculate the total  area (using garden radius plus path width) and then, subtract it the area of the circular garden.

We know that the radius of the circular garden is equal to 8 feet, and the circular path has a width of 3 feet, so, the radius of the circular path will be:

[tex]CPath_{radius}=8feet+Path_{width}\\\\Path_{radius}=8feet+3feet=11[/tex]

Now, calculating the areas, we have:

Garden Area:

[tex]CircularGardenArea=\pi *radius^{2}\\\\CircularGardenRadius=\pi *8ft^{2}=3.14*64ft^{2}=200.96ft^{2}[/tex]

Total Area:

[tex]TotalArea=\pi *(8feet+3feet)^{2}=\pi *(11ft)^{2}=3.14*121ft^{2}=379.94ft^{2}[/tex]

Now, calculating the area of the path, we have:

[tex]TotalArea=CircularGardenArea+PathArea\\\\PathArea=TotalArea-CircularGardenArea\\\\PathArea=379.94ft^{2}-200.96ft^{2}=178.98ft^{2}[/tex]

Hence, we have that:

[tex]PathArea=178.98ft^{2}[/tex]

D

Step-by-step explanation:

1 / tan(90 - x) = -√3/3                   Cross multiply

3 = -√3 * tan(90 - x)                     Divide by -√3

3/-√3 = tan(90 - x)                       Rationalize the denominator

3 * √3 /  (- √3 * √3  ) =tan(90-x)

3 * √3 / - 3 = tan(90 - x)               Divide

- √3           = tan(90 - x)               Take the inverse tan of -√3

tan-1(-√3) = 90 - x

Step-by-step explanation:

Final answer:

The truth value of the conditional statement ¬q → ¬p, with p being true and q being false, is false.

Explanation:

The question is asking about the truth value of the conditional statement ¬q → ¬p, where p is true and q is false. In a conditional statement of the form 'if q then p', written symbolically as q → p, the statement is false only when q is true and p is false. Otherwise, the statement is true. In this case, ¬q means 'not q' and ¬p means 'not p'. Given that q is false, ¬q is true. Given that p is true, ¬p is false. Thus, the statement ¬q → ¬p is of the form 'true → false', which makes the entire conditional statement false.

Final answer:

The truth value for the conditional statement ¬q → ¬p when p is true and q is false is false. This is because the contrapositive of any conditional statement must have the same truth value as the statement itself, and the given condition does not maintain this logical equivalence.

Explanation:

The truth value for the following conditional statement ¬q → ¬p when p is true and q is false is what we are trying to determine. The proposition ¬q → ¬p is the contrapositive of the conditional p → q. According to logic, a conditional proposition and its contrapositive always have the same truth value. Since we are given that p is true and q is false (¬q is true), using the definitions of the logical operators, we find that the contrapositive of the original conditional should also be true if the original is true.

In this case, the contrapositive is ¬q → ¬p, which, when translated in terms of the given truth values, becomes true → false. This suggests that if ¬q is true, then ¬p is true as well; however, since we know p is true, the situation given (¬q is true, ¬p is false) is not possible because it would not uphold the truth of the original proposition. Thus, the provided sequence of truth values does not maintain the logical equivalence of the contrapositive, making it incorrect. Therefore, the truth value of ¬q → ¬p is false under the given conditions.

Step-by-step explanation:

As per logarithmic relation

[tex]log_{base}\frac{A}{B}=log_{base}A-log_{base}B[/tex]

Now, in the given question base value is 3. Therefore

[tex]log_{3}\frac{c}{9}=log_{3}c-log_{3}9[/tex]

Hence the correct answer is third option.

The expression is equivalent to log₃ (c/9) is log₃ (c) - log₃ (9).

The power to which a number must be increased in order to obtain additional values is referred to as a logarithm. The easiest approach to express enormous numbers is this manner. Numerous significant characteristics of a logarithm demonstrate that addition and subtraction logarithms can also be written as multiplication and division of logarithms.

We have,

log₃ (c/9)

Step-by-step explanation:

To find just the remainder when dividing a polynomial by x-3, you could just plug in 3 into that polynomial.

If you were dividing by x+3, the remainder would just be the polynomial evaluated at x=-3.

Anyways plugging in 3 gives

7(3)^4 + 12(3)^3 + 6(3)^2 - 5(3) + 16

There are 86,400 / 3,600 = 24 frames/second

Step-by-step explanation:

Since there are 60 minutes in an hour and 60 seconds in a minute, in an hour you have 60 x 60 = 3,600 seconds.

You have 86,400 frames of animation in 1 hour.

Divide 86,400 by 3,600 to get the number of frames per second.

There are 86,400 / 3,600 = 24 frames/second

To solve, make a simple equation.

86400/3600=x

In order to get x, divide 86400 by 3600 and which x will be 24.

You can either divide the long way or the short way.

Answer:

-1280

Step-by-step explanation:

There are 2 ways you could do this. You could just do the question until you come to the end of f(4). That is likely the simplest way to do it.

f(1) = 160

f(2) = - 2 * f(1)

f(2) = -2*160

f(2) = -320

f(3) = -2 * f(2)

f(3) = -2 * - 320

f(3) = 640

f(4) = - 2 * f(3)

f(4) = - 2 * 640

f(4) = - 1280

I don't know that you could do this explicitly with any real confidence.

[tex]f(1)=160\\f(n+1)=-2f(n)\\\\f(2)=-2\cdot 160=-320\\f(3)=-2\cdot(-320)=640\\f(4)=-2\cdot 640=-1280[/tex]

Check the picture below, that's just an example of a parabola opening upwards.

so the cost equation C(b), which is a quadratic with a positive leading term's coefficient, has the graph of a parabola like the one in the picture, so the cost goes down and down and down, reaches the vertex or namely the minimum, and then goes back up.

bearing in mind that the quantity will be on the x-axis and the cost amount is over the y-axis, what are the coordinates of the vertex of this parabola?  namely, at what cost for how many bats?

[tex]\bf \textit{vertex of a vertical parabola, using coefficients} \\\\ C(b) = \stackrel{\stackrel{a}{\downarrow }}{0.06}b^2\stackrel{\stackrel{b}{\downarrow }}{-7.2}b\stackrel{\stackrel{c}{\downarrow }}{+390} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right)[/tex]

[tex]\bf \left( -\cfrac{-7.2}{2(0.06)}~~,~~390-\cfrac{(-7.2)^2}{4(0.06)} \right)\implies (60~~,~~390-216) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill (\stackrel{\textit{number of bats}}{60}~~,~~\stackrel{\textit{total cost}}{174})~\hfill[/tex]

To find the number of bats that should be produced to minimize costs, we need to find the minimum point on the cost curve given by the function C(b) = 0.06b^2 - 7.2b + 390. Using the vertex formula, we find that the minimum occurs at b = 60.

To find the number of bats that should be produced to keep costs at a minimum, we need to determine the minimum point on the cost curve given by the function C(b) = 0.06b^2 - 7.2b + 390. The minimum point of a quadratic function can be found using the vertex formula: b = -b / (2a), where a is the coefficient of the quadratic term and b is the coefficient of the linear term. In this case, a = 0.06 and b = -7.2. Plugging these values into the formula, we get b = -(-7.2) / (2 * 0.06) = 60.

Therefore, the number of bats that should be produced to keep costs at a minimum is 60.

Answer in standard form: [tex]P(x)=x^4-15x^3+61x^2+15x-350[/tex]

Step-by-step explanation:

I don't see your choices but I can still give you a polynomial fitting your criteria. I will give the answer in both factored form and standard form.

The following results are by factor theorem:

So if x=-2 is a zero then x+2 is a factor.

If x=7 is a zero then x-7 is a factor.

If x=5 is a zero then x-5 is a factor.  It says we have this factor twice.  I know this because it says with multiplicity 2.

So let's put this together.  The factored form of the polynomial is

A(x+2)(x-7)(x-5)(x-5)

or

[tex]A(x+2)(x-7)(x-5)^2[/tex]

Now A can be any number satisfying a polynomial with zeros -2 and 7 with multiplicity 1, and 5 with multiplicity 5.

However, it does say we are looking for a polynomial function with leading coefficient 1 which means A=1.

[tex](x+2)(x-7)(x-5)^2[/tex]

Now the factored form is easy.

The standard form requires more work (multiplying to be exact).

I'm going to multiply (x+2)(x-7) using foil.

Answer:

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

2) 1.5, -5

3) Open upwards from both ends

4) Minimum

Step-by-step explanation:

Step 1:

The given polynomial is:

[tex]2x^{2}+10x-3x-15[/tex]

Taking out commons, we get:

[tex]2x(x+5)-3(x+5)\\\\ =(2x-3)(x+5)[/tex]

This is the factorized form of the polynomial.

Step 2:

The zeros of the functions occur when the function is equal to zero.

i.e.

[tex](2x-3)(x+5)=0\\\\ \text{According to the zero product property}\\\\ 2x-3=0, x+5=0\\\\ x =\frac{3}{2}=1.5, x = -5[/tex]

This means, the zeros of the polynomial are 1.5 and -5

Step 3:

The end behavior of a graph depends on its degree and the sign of leading coefficient. Since the degree is even and the coefficient is positive the graph of the polynomial will opens upwards from left and right side.

Step 4:

The given polynomial is a quadratic function with positive leading coefficient. Since it open vertically upwards, its vertex will be the lowest most point. So, the vertex will be the minimum of the function.

So we want to probably find the standard form of this multiplication because writing (4x+3)(x-6)(2x-1) is too easy.

Let's multiply (4x+3) and (x-6), then take that result and multiply it to (2x-1).

(4x+3)(x-6)

I'm going to use FOIL here.

First:  4x(x)=4x^2

Outer:  4x(-6)=-24x

Inner:  3(x)=3x

Last:   3(-6)=-18

---------------------------Add.

4x^2-21x-18

So we now have to multiply (4x^2-21x-18) and (2x-1).

We will not be able to use FOIL here because we are not doing a binomial times a binomial.

We can still use distributive property though.

(4x^2-21x-18)(2x-1)

=

8x^3-46x^2-5x+18

Answer:

[tex]\large\boxed{8x^3-46x^2-15x+18}[/tex]

Step-by-step explanation:

The formula of a volume of a rectangular prism:

[tex]V=lwh[/tex]

l - length

w - width

h - height

We have l = 4x + 3, w = x - 6 and h = 2x - 1.

Substitute:

[tex]V=(4x+3)(x-6)(2x-1)[/tex]

use FOIL: (a + b)(c + d)

[tex]V=\bigg[(4x)(x)+(4x)(-6)+(3)(x)+(3)(-6)\bigg](2x-1)\\\\=(4x^2-24x+3x-18)(2x-1)\qquad\text{combine like terms}\\\\=(4x^2-21x-18)(2x-1)[/tex]

use the distributive property: a(b + c) = ab + ac

[tex]V=(4x^2-21x-18)(2x)+(4x^2-21x-18)(-1)\\\\=(4x^2)(2x)+(-21x)(2x)+(-18)(2x)+(4x^2)(-1)+(-21x)(-1)+(-18)(-1)\\\\=8x^3-42x^2-36x-4x^2+21x+18[/tex]

combine like terms

[tex]V=8x^3+(-42x^2-4x^2)+(-36x+21x)+18\\\\=8x^3-46x^2-15x+18[/tex]

Answer:

[tex]\huge \boxed{90}[/tex]

Step-by-step explanation:

First thing you do is subtract.

10-2=8

[tex]\displaystyle \frac{10!}{8!}[/tex]

Then you cancel the factorials.

[tex]\displaystyle \frac{10!}{8}=10\times9[/tex]

Multiply numbers from left to right to find the answer.

[tex]\displaystyle 10\times9=90[/tex]

[tex]\huge \textnormal{90}[/tex], which is our answer.

Hope this helps!

Final answer:

The value of 10!/(10-2)! simplifies to 90 after canceling out the common factorial terms, hence the correct answer is option C (90).

Explanation:

The expression 10!/(10-2)! represents a calculation involving factorials. The factorial of a number n is denoted n! and means the product of all positive integers from 1 up to n.

So, to simplify this expression, we can expand both factorials:

10! means 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1,
and (10-2)! or 8! means 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1.

When we divide 10! by 8!, the terms 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 (which is 8!) cancel out, leaving us with:

10 x 9 = 90.

Therefore, 10!/(10-2)! simplifies to 90, which is option C.
