My answer for multiplying is 6,732
My answer for dividing is 46.33333
Answer:
Step-by-step explanation:
There are 561 people.
When you divide by 12 you get 46 complete tables of 12
There are 9 people left over.
You can't round down. You must round up. These 9 people get a table all to themselves.
So you need 47 tables.

Answer:
[tex]\frac{1}{2\sqrt{5} }[/tex]
Step-by-step explanation:
Let, [tex]\text{sin}^{-1}(\frac{x}{6})[/tex] = y
sin(y) = [tex]\frac{x}{6}[/tex]
[tex]\frac{d}{dx}\text{sin(y)}=\frac{d}{dx}(\frac{x}{6})[/tex]
[tex]\frac{d}{dx}\text{sin(y)}=\frac{1}{6}[/tex]
[tex]\frac{d}{dx}\text{sin(y)}=\text{cos}(y)\frac{dy}{dx}[/tex] ---------(1)
[tex]\frac{1}{6}=\text{cos}(y)\frac{dy}{dx}[/tex]
[tex]\frac{dy}{dx}=\frac{1}{6\text{cos(y)}}[/tex]
cos(y) = [tex]\sqrt{1-\text{sin}^{2}(y) }[/tex]
= [tex]\sqrt{1-(\frac{x}{6})^2}[/tex]
= [tex]\sqrt{1-(\frac{x^2}{36})}[/tex]
Therefore, from equation (1),
[tex]\frac{dy}{dx}=\frac{1}{6\sqrt{1-\frac{x^2}{36}}}[/tex]
Or [tex]\frac{d}{dx}[\text{sin}^{-1}(\frac{x}{6})]=\frac{1}{6\sqrt{1-\frac{x^2}{36}}}[/tex]
At x = 4,
[tex]\frac{d}{dx}[\text{sin}^{-1}(\frac{4}{6})]=\frac{1}{6\sqrt{1-\frac{4^2}{36}}}[/tex]
[tex]\frac{d}{dx}[\text{sin}^{-1}(\frac{2}{3})]=\frac{1}{6\sqrt{1-\frac{16}{36}}}[/tex]
[tex]=\frac{1}{6\sqrt{\frac{36-16}{36}}}[/tex]
[tex]=\frac{1}{6\sqrt{\frac{20}{36} }}[/tex]
[tex]=\frac{1}{\sqrt{20}}[/tex]
[tex]=\frac{1}{2\sqrt{5}}[/tex]
15. Given Square ABCD, if AB = 2x + 4 and
CD = 3x - 5, find BC.
Equation: _____
X = _____
BC = _____
Answers
Answer:
equation : 2x + 4 = 3x - 5
X = 9
BC = 22
The equation will be - (2x + 4 = 3x - 5), x = 9 and BC = 22.
What is a square? What is a mathematical equation? What do you mean by domain and range of a function?In Euclidean geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles. It can also be defined as a rectangle with two equal-length adjacent sides.
Area: (side)²Perimeter: 4 x sideNumber of vertices: 4Number of edges: 4Internal angle: 90°Properties: Convex polygon, Equilateral polygon, Isogonal figure, Isotoxal figure, CyclicType: Quadrilateral, Regular polygonA mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
A mathematical equation is used to equate two expressions.
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is square ABCD and AB = 2x + 4 and CD = 3x - 5
Now -
AB = CD
Equation will be -
2x + 4 = 3x - 5
4 + 5 = 3x - 2x
x = 9
and
AB = BC = CD = AD = 2x + 4 = 2 x 9 + 4 = 22
BC = 22
Therefore, the equation will be - (2x + 4 = 3x - 5), x = 9 and BC = 22.

What is 16-12x=4y when you are solving the equation for x ?
Answers
Answer:
x = [tex]\frac{-1}{3}y[/tex] + [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
16 - 12x = 4y
Add -16 to both sides.
-12x + 16 + (-16) = 4y + (-16)
-12x = 4y - 16
Then divide both sides by -12
-12x / (-12) = [tex]\frac{4y-16}{-12}[/tex]
x = [tex]\frac{-1}{3}y[/tex] + [tex]\frac{4}{3}[/tex]

3.1 Find roots (zeroes) of : F(x) = 4x4+x3-2x2-6x+2
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 4 and the Trailing Constant is 2.
final result:
4x4 + x3 - 2x2 - 6x + 2
6x - 2 + 2x = -2 + 4x + 8
Simplifying
6x + -2 + 2x = -2 + 4x + 8
Reorder the terms:
-2 + 6x + 2x = -2 + 4x + 8
Combine like terms: 6x + 2x = 8x
-2 + 8x = -2 + 4x + 8
Reorder the terms:
-2 + 8x = -2 + 8 + 4x
Combine like terms: -2 + 8 = 6
-2 + 8x = 6 + 4x
Solving
-2 + 8x = 6 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
-2 + 8x + -4x = 6 + 4x + -4x
Combine like terms: 8x + -4x = 4x
-2 + 4x = 6 + 4x + -4x
Combine like terms: 4x + -4x = 0
-2 + 4x = 6 + 0
-2 + 4x = 6
Add '2' to each side of the equation.
-2 + 2 + 4x = 6 + 2
Combine like terms: -2 + 2 = 0
0 + 4x = 6 + 2
4x = 6 + 2
Combine like terms: 6 + 2 = 8
4x = 8
Divide each side by '4'.
x = 2

A 7-by-7 foot rug is shown. A coin is tossed onto the rug randomly. Which of these describes the probability that the coin will land on an area that is white? *
Answers
Answer :
The probability that the coin will land on an area that is white is [tex]\dfrac{1}{2}[/tex]
Explanation :
Given that,
A 7-by-7 foot rug is shown in figure.
Suppose, all parts are equal.
The area of rug is
[tex]A_{r}=7\times7[/tex]
Area of one part of rug is
[tex]A'_{1}=3.5\times3.5[/tex]
We need to calculate the probability that the coin will land on an area that is white
Using formula of probability
[tex]P=\dfrac{Area\of\ white\ part}{Area\of\ total\ rug}[/tex]
Put the value into the formula
[tex]P=\dfrac{(3.5\times3.5)+(3.5\times3.5)}{7\times7}[/tex]
[tex]P=\dfrac{2\times3.5\times3.5}{7\times7}[/tex]
[tex]P=\dfrac{1}{2}[/tex]
Hence, The probability that the coin will land on an area that is white is [tex]\dfrac{1}{2}[/tex].

You need 4 cups of orange juice and 3 cups of cranberry juice to make 7 total cups of fruit punch. How many cups of each juice do you need to make 28 cups of fruit punch?
Answers
Step-by-step explanation:
4 cups of orange juice + 3 cups of cranberry juice = 7 cups of fruit punch
28 = 4 * 7 so all you would need to do is multiply the number of cups by 4
4( 4 cups of orange juice + 3 cups of cranberry juice = 7 cups of fruit punch)
16 cups of orange juice + 12 cups of cranberry juice = 28 cups of fruit punch

What are the x - and y -intercepts of the equation 3x+4y=24?
Answers
Given:
The equation is
[tex]3x+4y=24[/tex]
To find:
The x- and y-intercepts of the given equation.
Solution:
We have,
[tex]3x+4y=24[/tex]
Putting x=0, we get
[tex]3(0)+4y=24[/tex]
[tex]0+4y=24[/tex]
[tex]y=\dfrac{24}{4}[/tex]
[tex]y=6[/tex]
Therefore, the y-intercept of the given equation is 6.
Putting y=0, we get
[tex]3x+4(0)=24[/tex]
[tex]3x+0=24[/tex]
[tex]x=\dfrac{24}{3}[/tex]
[tex]x=8[/tex]
Therefore, the x-intercept of the given equation is 8.

Function f is represented by f(x) = 5(x + 11)
A. Find f(-2)
Answers
Answer:
f(-2)=45
Step-by-step explanation:
f(x)=5(x+11)
x= -2
so basicly its just 5(-2+11)
which is -10+55 and that is 45
so f(-2)=45
Considering the given function, it is found that the numeric value at x = -2 is of f(-2) = 45.
What is the definition of the function?The function is defined by:
f(x) = 5(x + 11).
Hence, when x = -2, we have that:
f(-2) = 5(-2 + 11) = 5 x 9 = 45.
