Based on the calculations, 75% of this number (80) is equal to 60.

An equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.

In order to solve this word problem, we would assign a variable to the unknown number and then translate the word problem into algebraic equation as follows:

Let the number be n.

Translating the word problem into an algebraic equation, we have;

30% of a number is 24 would be given by:

30/100 × n = 24

0.30n = 24

n = 24/0.30

n = 80

45% of the same number is 36 would be given by:

45/100 × n = 36

0.45n = 36

n = 36/0.45

n = 80

Next, we would determine 75% of this number as follows:

Number = 75/100 × 80

Number = 0.75 × 80

Number = 60.

The limit does not exist.

In order for such a limit to occur, the fraction \(\frac{x^{2} }{x^{2} +y^{2} }\) must be comparable to the same value \(L\), regardless of the way we take to get there \((0,0)\).

Try approaching \((0,0)\) along the x-axis.

This means setting \(y=0\) and finding the limit \(lim_{x-0} \frac{x^{2} }{x^{2} +y^{2} }\).

We obtain:

\(lim_{x-0,y=0}\frac{x^{2} }{x^{2} +y^{2} } =lim_{y=0}}\frac{x^{2} }{x^{2} +0 }\\=lim_{x-0}} \frac{x^{2} }{x^{2} } \\\\=lim_{x-0}}1\\=1\)

Now evaluate approaching \((0,0)\) along the y-axis.

This means setting \(x=0\) and finding the limit \(lim_{y-0} \frac{x^{2} }{x^{2} +y^{2} }\).

\(lim_{y-0,x-0} \frac{x^{2} }{x^{2} +y^{2} } =lim_{y-0} \frac{0}{0+y^{2} } \\=lim_{y-0} \frac{0}{y^{2} } \\=lim_{y-0} 0\\=0\)

Approaching the origin via these two methods results in distinct limits.

\(lim_{x-0,y-0} \frac{x^{2} }{x^{2} +y^{2} }\) ≠ \(lim_{y-0,x-0}\frac{x^{2} }{x^{2} +y^{2} }\)

Therefore the limit does not exist.

Step-by-step explanation:

Create a blank frequency table:

\(\begin{array}{|l|c|c|c|}\cline{1-4} \vphantom{\dfrac12}& \sf Male & \sf Female & \sf Total\\\cline{1-4} \vphantom{\dfrac12}\sf Plays \; pickleball & & &\\\cline{1-4} \vphantom{\dfrac12}\sf Does\;not\;play\; pickleball & & &\\\cline{1-4} \vphantom{\dfrac12}\sf Column\;Totals&&& 100\%\\\cline{1-4}\end{array}\)

If 79% of the participants played pickleball, then 21% of the participants do not play pickleball.

Input these percentages into the table:

\(\begin{array}{|l|c|c|c|}\cline{1-4} \vphantom{\dfrac12}& \sf Male & \sf Female & \sf Total\\\cline{1-4} \vphantom{\dfrac12}\sf Plays \; pickleball & & & 79\%\\\cline{1-4} \vphantom{\dfrac12}\sf Does\;not\;play\; pickleball & & & 21\%\\\cline{1-4} \vphantom{\dfrac12}\sf Column\;Totals&&& 100\%\\\cline{1-4}\end{array}\)

Of those who play pickleball, 6% are female.

Therefore, of those who play pickleball, 94% must be male.

The total percentage of those who play pickleball is 79%, so find 6% and 94% of 79%:

\(\begin{aligned}\textsf{Plays pickleball (female)}&=6\% \; \sf of \; 79\%\\&=0.06 \times 0.79\\&=0.0474\\&=5\%\; \sf (nearest\;percent)\end{aligned}\)

Of those who do not play pickleball, 21% are male.

Therefore, of those who do not play pickleball, 79% must be female.

The total percentage of those who do not play pickleball is 21%, so find 21% and 79% of 21%:

\(\begin{aligned}\textsf{Does not play pickleball (male)}&=21\% \; \sf of \; 21\%\\&=0.21 \times 0.21 \\&=0.0441\\&=4\%\; \sf (nearest\;percent)\end{aligned}\)

Answer:

c

Step-by-step explanation:

i took the test :)

The city-states of Greece did not revolt more against the takeover by Macedonia due to factors such as military strength, political calculations, and lack of unity.

One reason is that Macedonia, under the leadership of Philip II and later his son Alexander the Great, had established a formidable military force. The Macedonian army was highly trained and experienced, making it challenging for individual city-states to resist their advances. The overwhelming military strength of Macedonia deterred many city-states from attempting to revolt.

Additionally, Macedonia employed a strategy of diplomacy and political maneuvering to consolidate power. Philip II and Alexander the Great skillfully formed alliances and forged relationships with influential individuals and city-states, sometimes offering them favorable terms or autonomy within their territories. These political calculations persuaded some city-states to accept Macedonian rule rather than risk conflict and potential destruction.

Furthermore, the city-states of Greece were not entirely unified and often engaged in rivalries and internal disputes. This lack of unity made it difficult to mount a coordinated resistance against Macedonia. Some city-states may have been hesitant to revolt against Macedonian rule out of fear of retaliation from neighboring city-states or a desire to maintain stability within their own territories.

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Let D represent the total cost for attending x lessons for Dan’s Dancing School and let L represent the total cost for attending x lessons for Larry’s Dancing School.

Dan’s Dancing School charges $85 for enrollment plus $6 per class. So, we can write the following equation:

\(D=6x+85\)

Larry’s Dancing School charges $40 for enrollment and $12 per class. So, we can write the following equation:

\(L=12x+40\)

Let’s find the value of x such that the cost will be the same. So, set the equations equal to each other and solve for x:

\(6x+85=12x+40\)

Subtract 6x from both sides:

\(85=6x+40\)

Subtract 40 from both sides:

\(45=6x\)

Divide both sides by 6:

\(x=7.5\)

Since we can’t have half a class, we need to round up to the nearest whole number.

However, notice that Larry’s class charges more per class than Dan’s. Therefore, for any number after 7.5, Larry’s class will be more expensive.

Since we can’t have 7.5 classes, we are rounding it to 8.

Therefore, after 8 or more classes, Larry’s class will be more expensive.

So, our correct answer is D.

Answer:

y + 2 = -2(x - 3)^2

Step-by-step explanation:

We can see immediately that the vertex is at (3, -2).  

The vertex form of the equation of a parabola is

y - k = a(x - h)^2.

If the parabola opened upward, the equation would be y + 2 = 2(x - 3)^2.  But seeing that this particular parabola opens downward, the equation is

y + 2 = -2(x - 3)^2.

Check:  Does the point (2, -4) satisfy this equation?

-4 + 2 = -2(2 - 3)^2 becomes -2 = -2(-1)^2, which is true.

What is trignomentry ?

Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles, particularly right triangles. It is used to study the properties of triangles and to solve problems involving angles and distances in two-dimensional space.

sin(π/6)cos(π/2) - cos(π/60)sin(π/2)

The first term in the expression, sin(π/6)cos(π/2), can be simplified as follows ,

sin(π/6) = √(3)/2, cos(π/2) = 0

so sin(π/6)cos(π/2) = (√(3)/2) * 0 = 0

The second term in the expression, -cos(π/60)sin(π/2) , can be simplified as follows ,

sin(π/2) = 1, cos(π/60) = sqrt(3)/2 - 1/2

so -cos(π/60)sin(π/2) = -(sqrt(3)/2 - 1/2) * 1 = -sqrt(3)/2 + 1/2

Now we can substitute the simplified values back into the original expression ,

0 - (-sqrt(3)/2 + 1/2)

and combining like terms, \(\frac{1-\sqrt{3} }{2}\),

Hence ,  The expression as a single real number is \(\frac{1-\sqrt{3} }{2}\) .

The answer is 11101 in binary, which is equivalent to the decimal number 29 using binary multiplication.

To perform binary multiplication, we use the same method as we do for decimal multiplication, but only with 0s and 1s.

So, to multiply 1011 and 101, we first write them down like this:

   1011
 x  101
 ------
 
Now we start with the rightmost digit of the second number (1), and multiply it with every digit of the first number, one by one, starting from the right:

   1 0 1 1
 x 1 0 1
 ------
   1 0 1 1
 0 0 0 0
 1 0 1 1
-------------

The first row represents the multiplication of the last digit of the second number (1) with every digit of the first number. The second row represents the multiplication of the second last digit of the second number (0) with every digit of the first number, and so on.

Now we add up all the rows, taking care to align them properly:

   1 0 1 1
 x 1 0 1
 ------
   1 0 1 1
 0 0 0 0
 1 0 1 1
-------------
 1 1 1 0 1

Answer:

p(x) = -4*x^4  - 2*x^3 + 3*x^2 + 1*x - 2

Step-by-step explanation:

We want to find a polynomial p(x), such that if we add that polynomial to:

f(x) = 4*x^4 + 2*x^3 - 2*x^2 + x - 1

we get:

g(x) = x^2 + 2*x - 3

This is:

f(x) + p(x) = g(x)

Notice that f(x) is a polynomial of degree 4 and g(x) is a polinomial of degree 2, so p(x) must be also a polynomial of degree 4.

p(x) = a*x^4 + b*x^3 + c*x^2 + d*x + e

Then we get:

(4*x^4 + 2*x^3 - 2*x^2 + x - 1) + (a*x^4 + b*x^3 + c*x^2 + d*x + e) = x^2 + 2*x - 3

We can simplify the left side to:

(4 + a)*x^4 + (2 + b)*x^3 + (-2 + c)*x^2 + (1 + d)*x + (-1 + e) =  x^2 + 2*x - 3

Because in the right side we do not have terms with exponent 4 and 3, we must have that:

4 + a = 0

2 + b = 0

and for the other exponents of x we just match the exponent in the left side with the correspondent one in the right side:

(-2 + c) = 1

(1 + d) = 2

(-1 + e) = -3

Solving the 5 equations we get:

a = -4

b = -2

c = 1 + 2 = 3

d = 2 - 1 = 1

e = -3 + 1 = -2

Then the equation for p(x) is:

p(x) = -4*x^4  - 2*x^3 + 3*x^2 + 1*x - 2

Answer:

A' = (-1, -1)

Step-by-step explanation:

Rule for the dilation of any point A(x, y) about the origin by a factor of k is given by the rule,

From the graph attached,

Coordinates of point A are (-3, -3) and it is dilated by a scale factor of \(\frac{1}{3}\) about the origin then the coordinates of the image point A' will be,

A(-3, -3) → \(A'(-3\times \frac{1}{3},-3\times \frac{1}{3})\)

             → A'(-1. -1)

Therefore, coordinates of A' = (-1, -1) is the answer.
