The expression represents an irrational number are B. √75 and D. √3-√3 .
What are irrational number?
Any number that cannot be expressed as the quotient of two integers i.e. p/q.
A. 0.18 = 18/100
⇒ it is expressed as quotient of two integers p/q.
∴ 0.18 is a rational number.
B. [tex]\sqrt{75}[/tex]
⇒it is not expressed as quotient of two integers p/q.
∴ It is an irrational number.
C. 2/3
⇒it is expressed as quotient of two integers p/q.
∴ 2/3 is a rational number.
D. √3-√3
⇒ √3-√3 is not expressed as quotient of two integers p/q.
∴ B. √75 and D. √3-√3 are irrational numbers.

the curve with the equation y=8x^2 + 2/x has one turning point.
Find the coordinates of this turning point.
Answer:
(1/2, 6).
Step-by-step explanation:
Turning points in a graph may exist whenever the derivative equals 0. Hence, let’s differentiate and then solve our function.
We have:
[tex]\displaystyle y=8x^2+\frac{2}{x}[/tex]
Take the derivative of both sides with respect to x:
[tex]\displaystyle y^\prime=16x-\frac{2}{x^2}[/tex]
Simplify:
[tex]\displaystyle y^\prime=\frac{16x^3-2}{x^2}[/tex]
We will now set this equal to 0 and solve for x. Hence:
[tex]\displaystyle \begin{aligned} 0&=\frac{16x^3-2}{x^2} \\ 0&=16x^3-2 \\ 2&=16x^3 \\ \frac{1}{8}&=x^3 \\ \frac{1}{2}&=x \end{aligned}[/tex]
Hence, the graph turns at x=1/2. This is the x-coordinate.
Then it follows that the y-coordinate will be:
[tex]\displaystyle{\begin{aligned} y&=8(\frac{1}{2})^2+\frac{2}{\frac{1}{2}} \\ y&=8(1/4)+2(2) \\ y&=2+4 \\ y&=6\end{aligned}[/tex]
Hence, our coordinate Is (1/2, 6).
Which is the graph of f(x) = x2 – 2x + 3?
Answer:
The correct answer is:
The graph will be the same width as the parent graph f(x) = x², but the vertex has been shifted to (1, 2).
Step-by-step explanation:
Since the value of a, the coefficient of x², is 1, this means the graph has not been stretched or shrunk. However, since the function is different than f(x)=x², we know that the vertex is not at (0, 0). We can write the function in vertex form to find the new vertex.
To write the function in vertex form, we find the value of b/2. The value of b in this function is -2; -2/2 = -1. We then square this: (-1)² = 1. This is what we add and subtract to the function (we must do both to preserve equality), giving us:
f(x) = x²-2x+1+3-1
The first three terms of this function can be written as the square (x+(b/2))²; this is (x-1)², and gives us f(x) = (x-1)²+3-1. Combining like terms, we have:
f(x) = (x-1)²+2
This is vertex form, f(x) = a(x-h)²+k, where (h, k) is the vertex. This means the vertex is at (1, 2) instead of (0, 0).

Your MOM has a 72 boyfriends and your dad see your mom cheating on you by kissing them and 9 of them jump off the window how many boyfriends are in the room still?
Given:
Total number of boyfriends = 72
Number of boyfriends who jump off the window = 9
To find:
The remaining number of boyfriends.
Solution:
We need to subtract the number of boyfriend who jump off the window from the total number of boyfriends to get the remaining number of boyfriends.
[tex]\text{Remaining boyfriends}=72-9[/tex]
[tex]\text{Remaining boyfriends}=63[/tex]
Therefore, the number of remining boyfriends is 63.

Step-by-step explanation:
Perimeter =116
Yes plz need help
Answer:
[tex]x=30[/tex]
Step-by-step explanation:
First, let us notice that the ticks on the side of this quadrilateral indicate that the lengths of the sides are equal.
From this, we can create the following equation based on the perimeter of this shape.
[tex]28+28+x+x=116[/tex]
Now, we can solve this equation for x by first combining like terms
[tex]2x+56=116[/tex]
Now, we can subtract 56 from each side
[tex]2x=60[/tex]
And now divide each side by 2
[tex]x=30[/tex]
Just to check out answer, we can plug this x-value into our original perimeter equation to see if it is correct
[tex]28+28+30+30=116\\\\56+60=116\\\\116=116[/tex]

You are given an expression for the volume of the rectangular prism. Determine an expression for the missing dimension.
V equal 4 x to the power of 3 plus 5 x to the power of 2 minus 32 x minus 33 and the dimensions are ( x + 1 ) and ( x + 3 ) .
Given:
The volume of the rectangular prism is
[tex]V=4x^3+5x^2-32x-33[/tex]
Two dimensions are (x+1) and (x+3).
To find:
The missing dimension.
Solution:
We know that, volume of a rectangular prism is
[tex]V=length\times breadth\times height[/tex]
It means, volume of a rectangular prism is the product of all dimensions.
We have,
[tex]V=4x^3+5x^2-32x-33[/tex]
Splitting the middle terms, we get
[tex]V=4x^3+4x^2+x^2+x-33x-33[/tex]
[tex]V=4x^2(x+1)+x(x+1)-33(x+1)[/tex]
[tex]V=(x+1)(4x^2+x-33)[/tex]
Splitting the middle term, we get
[tex]V=(x+1)(4x^2+12x-11x-33)[/tex]
[tex]V=(x+1)(4x(x+3)-11(x+3))[/tex]
[tex]V=(x+1)(x+3)(4x-11)[/tex]
So, the three dimensions of the rectangular prism are (x+1), (x+3) and (4x-11).
Therefore, the missing dimension is (4x-11).
Answer:
the missing dimension is (4x-11).The “strike zone” or distance across home plate is 17 inches. Determine how long a baseball pitched at 90 mph is in the strike zone. Show your work
Answer:
The ball will spend 10,730.4012 microseconds in the strike zone
Step-by-step explanation:
Here, we want to calculate the time spent by a ball in the strike zone given the distance across the strike zone and the speed of the ball
Mathematically, we have ;
time = distance/speed
Before we proceed to use this formula, we need to have the parameters in the same units
So let’s convert 17 inches to miles
Mathematically;
1 inch = 1.578 * 10^-5 mile
So 17 inches = 1.578 * 10^-5 * 17 = 0.00026826 miles
So let’s now calculate the time
That will be;
0.00026826/90 = 0.000002980667 hours
It will be best if we convert this to seconds
Mathematically,
60 seconds = 1 minute
60 minutes = 1 hour
So the number of seconds in an hour is 60 * 60 = 3600 seconds
= 0.000002980667 * 3600 = 0.0107304012
Mathematically, 1 second = 10^6 microseconds
Thus multiplying 0.0107304012 by 10^6
we have; 10,730.4012 micro seconds

A sailor on Ship A measures the angle between Ship B and the pier and finds it to be 39°. A sailor on Ship B measures the angle between Ship A and the pier and finds that it is 58°. What is the measure of the angle between Ship A and Ship B?
The measure between Ship A and Ship B is
Answer:
[tex]83^{\circ}[/tex]
Step-by-step explanation:
Let [tex]C[/tex] be the point that denotes the pier.
[tex]m\angle B=58^{\circ}[/tex]
[tex]m\angle A=39^{\circ}[/tex]
The angle between A and B is C
[tex]m\angle A+m\angle B+m\angle C=180^{\circ}\\\Rightarrow m\angle C=180^{\circ}-(m\angle A+m\angle B)\\\Rightarrow m\angle C=180^{\circ}-(58^{\circ}+39^{\circ})\\\Rightarrow m\angle C=83^{\circ}[/tex]
The measure of the angle between Ship A and Ship B is [tex]83^{\circ}[/tex].

A 12 cm by 16 cm painting hangs in a museum. The museum curator wants to hang other paintings in the gallery that are proportional (ratios which are equivalent) in size. The dimensions of several paintings are shown. Which paintings' dimensions are proportional to the original painting? Select all that apply.
A. 6 cm by 12 cm
B. 15 cm by 20 cm
C. 3 cm by 4 cm
D.6 cm by 9 cm
E. 9 cm by 12 cm
Answer: 15cm by 20cm
3cm by 4cm
9cm by 12cm
Step-by-step explanation:
From the question, we are informed that a 12 cm by 16 cm painting hangs in a museum. We are given several options and told to choose the paintings' dimensions that are proportional to the original painting. This will be:
12cm by 16cm when divided by 4 gives 3cm by 4cm. This means that we have to look out for the options that are in the ratio 3:4.
A. 6 cm by 12 cm
6cm by 12cm reduced to lowest term gives 1:2
B. 15 cm by 20 cm
15cm by 20cm reduced to lowest term gives 3:4
C. 3 cm by 4 cm
D.6 cm by 9 cm
6cm by 9cm reduced to lowest term gives 2:3.
E. 9 cm by 12 cm
9cm by 12cm reduced to lowest term gives 3:4.
Therefore the correct options are:
15cm by 20cm
3cm by 4cm
9cm by 12cm
