For x = 0 and y = -1
[tex]y = x^{2} -1[/tex]
We can substitute x = 0 and y = -1 values,
-1 = [tex]0^{2}[/tex] - 1
-1 = 0-1
-1 = -1
Then the x = 0 and y = -1 represented by rule [tex]y = x^{2} -1[/tex] is correct the error.
For x = 1 and y = 1
[tex]y = x^{2} -1[/tex]
We can substitute x = 1 and y = 1 values,
[tex]y = x^{2} -1[/tex]
1 = [tex]1^{2}[/tex] -1
1 = 1-1
1 ≠ 0
Then the x = 1 and y = 1 represented by rule [tex]y = x^{2} -1[/tex] is incorrect the error.
For x = 2 and y = 3
[tex]y = x^{2} -1[/tex]
We can substitute x = 2 and y = 3 values,
[tex]y = x^{2} -1[/tex]
3 = [tex]2^{2}[/tex] - 1
3 = 4 -1
3 = 3
Then the x = 2 and y = 3 represented by rule [tex]y = x^{2} -1[/tex] is correct .
For x = 3 and y = 5
[tex]y = x^{2} -1[/tex]
We can substitute x = 3 and y = 5 values,
[tex]y = x^{2} -1[/tex]
5 = [tex]3^{2}[/tex] - 1
5 = 9 - 1
5 ≠ 8

For x = 4 and y = 7
[tex]y = x^{2} -1[/tex]
We can substitute x = 4 and y = 7 values,
[tex]y = x^{2} -1[/tex]
7 = [tex]4^{2}[/tex] - 1
7 = 16 - 1
7 ≠ 15
Then the x = 4 and y = 7 represented by rule [tex]y = x^{2} -1[/tex] is incorrect the error.
Therefore,
The function represented by the rule [tex]y = x^{2} -1[/tex] is ,
x = 0 and y = -1 represented by rule [tex]y = x^{2} -1[/tex] is correct the error.
x = 1 and y = 1 represented by rule [tex]y = x^{2} -1[/tex] is incorrect the error.

find the distance of a speed of 15m/s for 5 minutes
15m/s * 1km/1000m*60s/1 min*60 min/1hr=
You do the calculation.
Here are the conversions used in the conversion.
1km = 1000 m, 60 seconds = 1 minute, 60 minutes = 1 hour.
When you set up the problem the 15 meters is in the numerator and 1 second is in the denominator. To convert the 15 meters to km the next conversion factor needs to have 1km in the numerator and 1000 meters in the denominator. Now the 15 m will be divided by 1000 m which cancels the meters and leaves km.
The seconds in 15 m/s is in the denominator so to convert seconds to hours multiply by 60 seconds placing it in the numerator over 1 minutes. Use the same idea to set up the conversion from minutes to hours.
Practice this conversion. It is a fundamental conversion that any middle school student should know how to do.

The height of the box is 12cm, having volume = 1200cm ³ .
What is the volume of triangular prism?A triangular prism's volume is the area that it takes up in all three dimensions. A prism is a solid object that has the same cross-section throughout its entire length, equal bases, and flat, rectangular side faces. Prisms can be divided into many categories and given different names depending on the form of their bases. A triangular prism has three rectangular lateral sides and two identical triangular bases.
The formula yields the volume of a triangular prism.
Volume of triangular prism = 1/2lwh
Where,
w = width
h = height
l = length.
We may determine the height by filling in the specified measurements.
1200cm ³ = 1/2 × (20 cm) × (10 cm) × h
h = (1200 cm³) / (100 cm²))
h = 12 cm
The box has a 12 centimeter height.

Answer:
10.97 mm
Step-by-step explanation:
Hello!
First, let's construct an altitude, as shown in the picture below. An altitude is a height from one point to another side, forming a 90° angle at that intersection.
The length of the altitude is the same as the missing length, they are both parallel.
The length from the altitude to the slant line would be 6, as found by subtracting 8 from 14.
If you look closely, we can see a right triangle, and 12.5 mm is the hypotenuse. We know the measure for another side, and we can solve for the altitude using the Pythagorean Theorem: [tex]a^2 + b^2 = c^2[/tex], a and b are legs, and c is the hypotenuse.
In this case, 6 and the altitude are legs.
Solve for the Altitude[tex]a^2 + b^2 = c^2[/tex][tex]A^2 + 6^2 = 12.5^2[/tex][tex]A^2 + 36 = 156.25[/tex][tex]A^2 = 120.25[/tex][tex]A = \sqrt{120.25}[/tex][tex]A \approx 10.97[/tex]The altitude is around 10.97, so the missing length will also be 10.97 mm.

David fills an aquarium to a depth of 3/8 meters in 3 3/5 minutes.
The unit rate in minutes per meter is 28.8 minutes per meter when David fills an aquarium to a depth of 3/8 meters in 3 3/5 minutes
The given Depth of the aquarium = 3/8 meters
Time taken to fill the aquarium = 3 3/5 minutes
To find the the unit rate in minutes per meter, we need to divide the time taken to fill the aquarium by the depth of the aquarium
So, Unit rate in minutes per meter = 3 3/5minutes ÷ 3/8 meters
= 18/5 ÷ 3/8
= 18/5 ×8/3
= 144/15
= 28.8 minutes per meter
Hence, the unit rate in minutes per meter is 28.8 minutes per meter when David fills an aquarium to a depth of 3/8 meters in 3 3/5 minutes
The correct question is David fills an aquarium to a depth of 3/8 meters in 3 3/5 minutes. What is the unit rate in minutes per meter?

suppose that there are seven committees with each pair of committees having a common member and each person being on two committees. how many people are there?
Minimum number of meeting required is 5 meetings required
As mentioned, if there is an edge between two committees, both the committee has atleast one member in common.
So if we consider two committees with atleast one member in common, i.e. we select two different vertices with an edge in between, the common member(s) in the committee can discuss and exchange ideas between the committees and thus they don't require a meeting to be scheduled.
So looking at the graph we can say that we only need to schedule meetings between committee with no edge connecting them.
6C2 - |E| or 15 - 10
= 5 meetings
What is the role of the committees?Committees keep an eye on ongoing government activities, spot problems that warrant legislative scrutiny, collect and assess data, and suggest courses of action to the Senate.

We have to find the slope of d.
The slope formula is to determine a line's slope or steepness, use the slope formula. By calculating the ratio of the change in the y-axis to the change in the x-axis, it may be used to calculate the slope of any line. A line's slope is determined by how its "y" coordinate changes in relation to how its "x" coordinate changes.
Slope m = rise/run =[tex]=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
Here, [tex](x_{1} ,y_{1} )=(5,1) and (x_{2} ,y_{2} )=(9,8)[/tex]

logp(5) = x, logp(7) =y
Write logp([5p^2]/49) in terms of x and y
The expression is x+2-2y
It is given to us that logp5=x and logp7=y
Now we are required to find logp(5p^2)/49 in terms of x and y
we know that in logarithmic formulas
loga^b=b loga
logab = log a+log b
log a/b= log a- log b
Now using these formulas to find the solution,
logp 5p^2/49
= logp5+ logp p^2 -log 49
=logp5+2 logpp-2log7
we know that logpp=1,hence
= logp5+2 -2 logp7
=x+2-2y
Hence the expression is x+2-2y

On a number line where A is at 5 and B is at 50, and X is the midpoint and T is somewhere between A and B, the coordinates of point T is 15 and the distance of XB is 22.5.
A number line is straight line divided by equal measures that serves as a visual representation of the real numbers.
If on a number line, a is at 5 and b is at 50, then AB = 50 - 5 = 45.
If point X is the midpoint of A and B, then X divides the distance of A to B into two equal parts.
let n = AX = XB
AB = AX + XB
45 = n + n
45 = 2n
n = 22.5
AX = XB = 22.5
If point T is 2/3 of the way from X to B, then
T = 2/3XB
T = 2/3(22.5)
T = 15
Hence, the coordinates of T is at 15 and the distance of XB is 22.5.

Solving the equation s = zr - 6zc^4 for z would give you: [tex]z = \frac{s}{r - 6c^4}[/tex].
How to Solve an Equation?Given the equation, s = zr - 6zc^4, to solve the equation for z, follow the steps below:
We have to isolate the variable "z" to one side of the equation if we are to solve the equation for z.
s = zr - 6zc^4
Factor out variable z
s = z(r - 6c^4)
Divide both sides of the equation by (r - 6c^4)
s/(r - 6c^4) = z(r - 6c^4) / (r - 6c^4)
s/(r - 6c^4) = z
[tex]z = \frac{s}{r - 6c^4}[/tex]
Therefore, solving the equation s = zr - 6zc^4 for z would give you: [tex]z = \frac{s}{r - 6c^4}[/tex].

how do you find the domain and range of a continuous graph???
Answer:
So, when talking about continuous functions, we're dealing with a function/graph that goes on and on to infinity. It never ends. In a case like this, we must define domain and range. Domain is all input values, while range goes the same but it's the output values. With this information, the domain and range on a continues graph would most likely be all real numbers due to the fact of the graph never ending, and that means the graph would have every input value thus making its domain/range infinite as well.
