Step-by-step explanation:

The volume generated by revolving this region around line x = 3 is 135/2 cubic unit.

Now,

y = 9−x² is an inverted parabola with vertex at  (0,9)

It cuts positive x- axis at  x = 3

In the region enclosed is rotated about  x = 3

Considering the cut with a plane perpendicular to the y axis, we obtain a circular ring with interior radius 3−x and exterior radius 3.

Its area is \(\pi (3^2(3-x)^2)\)  

Consider a disk of this area and this height dy. The sum of the volume of all these slices from y = 0 to y = 9 gives the desired volume. The summation is performed by integration.  

   \(V=\int\limits^9_0 {\pi (3^2(3-x)^2)} \, dx\)                    

and, y = 9-x²

⇒ dy = -2xdx, where the limits are from 0 to 9.

Now,

   \(V=\int\limits^9_0 {\pi (3^2(3-x)^2)} \, (-2xdx)\)

⇒ \(\pi (4x^3-\frac{x^4}{2}\) )  limits are from 0 to 3

⇒ \(\pi (4.3^3-\frac{3^4}{2})\)

= 135/2 cubic unit.

Large cat's meal tastes more like tuna fish

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

Zane's cat loves tuna fish

so he adds 2 ounces of tuna fish to 10 ounces of cat food for small cat

and he adds 3 ounces of tuna fish to 12 ounces of cat food for large cat

to know whose meal tastes as tuna fish calculate their percentages

for small cat 2% is added to 10%

that means (2/12)*100=16.6

for large cat 3% is added to 12%

that means (3/15)*100=20

Answer:

1330.5

Step-by-step explanation:

The equation for volume of a cylinder is:

\(V=r^{2} h\)

Now, we have to input our values

\(V = 5.5^{2} (14)\)

And solve!

\(5.5^{2} = 30.25\)

30.25 × 14 = 1330.46

Finally we have to round to the 1 decimal place

1330.46 = 1330.5

(Wondering why I used 5.5 instead of 11 for the radius? Well, the radius of a circle/cylinder is from the center point to the end so 11/2 = 5.5)

Answer:

15/16

Step-by-step explanation:

In a dice, there are 3 even and 3 odd numbers.

So, to calculate the required probability, we will have to calculate the probability of getting an odd number in all of them.

Probability of getting odd number in 1 dice = 3/6 = 1/2

Probability of getting odd number in 4 dice =

1/2 x 1/2 x 1/2 x 1/2 = 1/16

Therefore, probability of getting atleast one even number is 1 - 1/16 = 15/16

15/16 is the answer.

ABCD is 6 units 2×3=6

im not really sure about RST but i think it would be 4 or 5 units because it just looks like there is about that many inside.

We can see here that the area of quadrilateral ABCD = 12 units².

While the area for triangle RST = 5 units².

A quadrilateral is a polygon with four sides, four vertices, and four angles. The word "quadrilateral" is derived from the Latin words "quadri" (meaning "four") and "latus" (meaning "side"). Quadrilaterals are classified based on the lengths of their sides, the measures of their angles, and other specific properties.

Area of the parallelogram ABCD = B × H = 3 units × 4 units = 12 units².

Area of the triangle RST = 1/2bh = 1/2 × 5 units × 2 units = 1/2 × 10 units = 10/2 units = 5 units².

Answer:

- 15

Step-by-step explanation:

\( \frac{1}{3} a = - 5 \\ \\ a = - 5 \times 3 \\ \\ a = - 15\)

Answer:

-15

Step-by-step explanation:

As you can see, the denominator of 1/3 is 3. 1 third of a is -5. So what you do is, you multiply -5 * 3 and that'll give you -15. So, it is equal to -15.

Given the quadratic function has zeros at `x = 3` and `x = 9`, we can write the function in factored form as:\(\[f(x) = a(x - 3)(x - 9)\]\) where `a` is a constant.

Since the function goes through the point `(1, 32)`, we can use this to solve for `a`. Plugging in `\(x = 1` and `f(x) = 32`\), we get:\([32 = a(1 - 3)(1 - 9) = -16a\]  , `a = -2`.\)

Substituting this back into the factored form, we get:\(\[f(x) = -2(x - 3)(x - 9)\]\)Expanding this gives the equation for the quadratic function: \[f(x) = -2x^2 + 24x - 54\]2.

Since `f(x)` is a quadratic function, it can be written in the form: \[f(x) = ax^2 + bx + c\]We know that `f(-1) = -2`, `f(0) = -1`, and `f(1) = 0`.

Using this information, we can write three equations in terms of `a`, `b`, and `c`:\(\[a(-1)^2 + b(-1) + c = -2\]\)\\([a(0)^2 + b(0) + c = -1\]\)Simplifying each equation, \(\[f(x) = a(x - 3)(x - 9)\]\)

we get:\[a - b + c = -2\]\[c = -1\]\[a + b + c = 0\] Substituting `c = -1` into the first and third equations gives a system of two equations in two variables:\[a - b - 1 = -2 \ Rightarrow a - b = -1\]\[a + b - 1 = 0 \ Rightarrow a + b = 1\] Solving this system of equations, we get `a = 1` and `b = 0`.  

the quadratic function is:\[f(x) = x^2 - 1\]

Answer:

The linear equation is y = 450 - 30 x, where y is the number of pages

Lourdes has left to read after x days

Step-by-step explanation:

Each day, Lourdes reads 30 pages of a 450-page book

- We need to write a linear equation to represent the number of pages

 Lourdes has left to read after x days

∵ Lourdes reads 30 pages each day

∵ Lourdes will read for x days

∴ The number of pages Lourdes will read in x day = 30 x

- The left pages will be the difference between the total pages of the

 book and the pages Lourdes read

∵ The book has 450 pages

∵ Loured will read 30 x in x days

∴ The number of pages left = 450 - 30 x

- Assume that y represents the number of pages Lourdes has left

 to read after x days

∴ y = 450 - 30 x

The linear equation is y = 450 - 30 x, where y is the number of

two numbers have to equal 180 degrees. The biggest numbers can only be 90+90 and that is a right angle.

Answer:

m∠1 = 54° m∠2 = 63° m∠3 = 117°

Step-by-step explanation:

We know that 117 + m∠2 = 180°, which when calculated is equal to 63. Now, we know that 63 + 63 + m∠1 = 180°. This comes out to be 54°. Finally, we know that m∠3 has to equal 117° because they are same side interior angles.

The measure of m<1, m<2 and m<3 are 54, 63 and 63 degrees respectively

The sum of angle in a straight line is 180 degrees, hence:

m<2 + 117 = 180

m<2 = 180 - 117

m<2 = 63 degrees

For the diagram, m<2 - m<3 = 63 degrees (alternate angle.)

Also, the sum of interior angle of the triangle is 180 degrees, hence:

m<2 + m<2 + m<1 = 180

63 + 63 + m<1 = 180

126 + m<1 = 180

m<1 = 180 -126

m<1 = 54degrees

Hence the measure of m<1, m<2 and m<3 are 54, 63 and 63 degrees respectively

Step-by-step explanation:

The proof fails to demonstrate that there is an integer k such that n < k < n+2.

The proof you provided is incorrect. Let's analyze the statement and the proof:

Statement: For every integer n, there is an integer k such that n < k < n+2.

Proof (incorrect):

Suppose n is an arbitrary integer.

Therefore, k = n + 1.

The error in the proof lies in step 2. While it is true that k = n + 1 is an integer, it does not necessarily satisfy the condition that n < k < n+2. In fact, if we substitute k = n + 1 into the inequality, we get:

n < n + 1 < n + 2

This simplifies to:

n < n + 1 < n + 2

The inequality is not satisfied since n + 1 is not guaranteed to be less than n + 2. Therefore, the proof fails to demonstrate that there is an integer k such that n < k < n+2.

Step-by-step explanation:

because area equals length times width

Answer and Step-by-step explanation:

First, let's split the figure into two common shapes that we know the area formula for.

The top shape can become a triangle, while the bottom shape can become a rectangle.

We know the area of a triangle is

\(A = \frac{bh}{2}\)

and the area of a rectangle is

A = lw

Where:

A = Area

b = Base length (length)

h = Height

l = Longer length of a side

w = Smaller length of a side

Area of a Triangle:

b = 3

h = 3

A = \(\frac{3 * 3}{2}\)

A = 4.5

Area of a Rectangle:

w = 3

l = 8

A = 3 × 8

A = 24

Now we add together the areas to get the area of the figure.

Area of the Figure:

A = 4.5 + 24

A = 28.5

The area of the figure is 28.5 \(units^{2}\).

We conclude that:

\(c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2\)

Step-by-step explanation:

Given the expression

\(\frac{4}{2n}+\frac{5}{3c}=1\)

Let us solve for 'c'

\(\frac{4}{2n}+\frac{5}{3c}=1\)

Least Common Multiplier of 2n, 3c:   6nc

Now multiply both sides by LCM = 6nc

\(\frac{4}{2n}\cdot \:6nc+\frac{5}{3c}\cdot \:6nc=1\cdot \:6nc\)

Simplify

\(12c+10n=6nc\)

Subtract 10n from both sides

\(12c+10n-10n=6nc-10n\)

Simplify

\(12c=6nc-10n\)

Subtract 6nc from both sides

\(12c-6nc=6nc-10n-6nc\)

Simplify

\(12c-6nc=-10n\)

Factor 12c - 6nc = 6c(2-n)

\(6c\left(2-n\right)=-10n\)

Divide both sides by 6(2-n);  n≠2

\(\frac{6c\left(2-n\right)}{6\left(2-n\right)}=\frac{-10n}{6\left(2-n\right)};\quad \:n\ne \:2\)

simplify

\(c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2\)

Therefore, we conclude that:

\(c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2\)
