Answer:
Yes
Step-by-step explanation:
In mathematics, there are real numbers, imaginary numbers, and complex numbers. Is there any other category? We have infinite Cardinal and Ordinal numbers, not covered above.
Step-by-step explanation:
that is a tricky question.
basically all numbers we know are either a real or an imaginary number.
but there are many sub-types and one super-type that are defined in mathematics.
the superset of real and imaginary numbers is called complex numbers. that means it contains all real and all imaginary numbers.
the real numbers have then many sub-types :
e.g.
natural numbers
whole numbers
integer numbers
rational numbers
irrational numbers
so, you see, if the question means if there are any additional forms of numbers than real and imaginary numbers, then no.
if the question means if there are more number type definitions than just real and imaginary numbers, then yes.

Consider the following "generic rectangle" where the area of each region is given. Write equivalent
expressions that express the area of the whole rectangle as a sum and as a product.
Answer:
sum: 3x² -4x -4product: (x -2)(3x +2)Step-by-step explanation:
The areas of four regions are given. We can simply add them to find the sum. To express them as a product, we need to look at common factors.
SumThe total of the given area expressions is ...
3x² +2x -6x -4 = 3x² -4x -4 . . . . sum
ProductExtending the table to show common factors of each row and column, we have ...

The arc length is 0.785 units and the diagonal is √2 units
How to determine the lengths?The question requires that we determine the lengths of the blue line and the arc
The blue line is the diagonal of the square, whose side length (l) is
l = 1
The diagonal is then calculated as:
[tex]d = l * \sqrt 2[/tex]
This gives
[tex]d = 1 * \sqrt 2[/tex]
[tex]d = \sqrt 2[/tex]
The diagonal divides the vertex of the square into 45 degrees a piece, and the diagonal represents the radius of the arc
This means that:
[tex]r = \sqrt 2[/tex]
[tex]\theta = 45^o[/tex]
The arc length is:
[tex]l = \frac{\theta}{360} * \pi r^2[/tex]
So, we have:
[tex]l = \frac{45^o}{360} * 3.14 * \sqrt 2^2[/tex]
This gives
[tex]l = \frac{282.6}{360}[/tex]
Divide
l = 0.785
Hence, the arc length is 0.785 units and the diagonal is √2 units

What is the slope-intercept equation of the line below?
Answer:
D
Step-by-step explanation:
We will use the 2 coordinates marked on the graph as the reference.
The coordinates are:
A(4,-2)
B(0,3)
We know that the standard form for equation of line is:
y = mx+c
where m is the slope of the equation
and c is the y-intercept.
Very clearly, the y-intercept is where the line intercepts the y line.
and in this case, y-intercept = c = 3.
Now we know that the equation of line is now
y = mx + 3
To find m, the slope, we can use the 2 above coordinates.
slope of line = [tex]\frac{y1-y2}{x1-x2} \\=\frac{-2-3}{4-0} \\=\frac{-5}{4} \\=-\frac{5}{4}[/tex]
(Note: There is a 2nd way to find the slope in this case, let me know if you are interested to find out.)
Equation of line: [tex]y=-\frac{5}{4} x+3[/tex]
Therefore the answer is D.

Step-by-step explanation:
log 9-log 4÷log 3-log 2
Step-by-step explanation:
whoever created the original question and then probably the people copying it need to focus on writing these things correctly.
I assume this means
log(9) - log(4) ÷ log(3) - log(2)
or is anything combined in brackets ? like it could be e.g. log(4 ÷ log(3)). just as example.
and I guess we mean logarithm to the base of 10, right ?
anyway, if my assumptions are correct, then we only need to follow the regular priorities of mathematical operations :
1. brackets
2. exponents
3. multiplications and divisions
4. additions and subtractions
so, we need to start with the division in the middle, and then do the subtractions.
log(4) ÷ log(3) = 1.261859507...
log(9) - 1.261859507... = -0.307616998...
-0.307616998... - log(2) = -0.608646993...
or was the original question
(log(9) - log(4)) ÷ (log(3) - log(2))
?
that would be way more interesting.
we use the rules of logarithm :
e.g.
log(a×b) = log(a) + log(b)
log(a/b) = log(a) - log(b)
so, we have then
log(9/4) ÷ log(3/2)
and that is equal to
log(3/2 × 3/2) ÷ log(3/2)
(log(3/2) + log(3/2)) ÷ log(3/2) = 1 + 1 = 2
if that is the case, you really, REALLY need to pay more attention to brackets and other symbols in problem definitions.
A population of bacteria begins with 1500 bacteria and grows to 4500 in one hour.
- Find a function that represents the growth of this culture of bacteria as a function of time.
- How long does it take this culture of bacteria to double?
Thanks TT
The function that represents the growth of this culture of bacteria as a function of time is; P = 1500e^(1.0986t)
How to calculate Exponential Growth?
The formula for exponential growth is;
P = P₀e^(rt)
where;
P = current population at time t
P₀ = starting population
r = rate of exponential growth/decay
t = time after start
Thus, from our question we have;
4500 = 1500 * e^(r * 1)
4500/1500 = e^r
e^r = 3
In 3 = r
r = 1.0986
Thus, the function that represents the growth of this culture of bacteria as a function of time is;
P = 1500e^(1.0986t)
For the culture to double, then;
P/P₀ = 2. Thus;
e^(1.0986t) = 2
In 2 = 1.0986t
t = 0.6931/1.0986
t = 0.631 hours

We have:
The probability of H is 2/3 and the probability of T is 1/3.
P(HT) = P(H in the first trial)P(T in the second trial)

Find the length of each piece The shorter piece is The longer piece is ft long. ft long. Ahanu cuts a board that is 2.25 ft long into two pieces , where one piece is 3 inches longer than the other piece . Find the length of each piece .
Answer:
The shorter piece is 1.5 ft long.
The longer piece is 1.75 ft long.
Step-by-step explanation:
We are given that one piece is 3 inches longer than the other, which we can convert to 0.25 ft. We are also told that the total length of the board is 2.25 ft. This means that the two pieces must have lengths that add up to 2.25 ft.
Therefore, we can set up the equation:
x + (x + 0.25) = 2.25
Solving for x, we find that x = 1.5 ft, which is the length of the shorter piece. The length of the longer piece must then be 1.75 ft.

Pretend that you are the owner of a candy store. You have twenty pounds of cashews, which cost $3.55 a pound, and you have some peanuts, which cost $2.50 a pound. How many pounds of peanuts would you have to mix with the cashews to get a mixture that costs $3.20 per pound?
A. 10 pounds B. 9 pounds C. 7 pounds D. 8 pounds
Answer:
10 pounds
Step-by-step explanation:
So you have some given information:
(Price of cashews per pound) = 3.55
(Amount of cashes) = 20 pounds
(Price of peanuts, per pound) = 2.50
Now what you're looking for is the amount of peanuts you need to get a mixture of 3.20 per pound. So to find the price per pound. You would take the entire price and divide it by the amount of pounds. So generally it can be expressed as: [tex]\text{price per pound} = \frac{\text{price}}{\text{pounds}}[/tex] . In this equation we know we already have 20 pounds of cashews and they cost 3.55 per pound. We also know what the price per pound of the mixture is going to be, it's going to be 3.20. In the equation I'll express the amount of peanuts as "P" So we have the equation:
Plug in known values:
[tex]3.20 = \frac{20(3.55) + P(2.50)}{20+P}[/tex]
Multiply:
[tex]3.20 = \frac{71 + 2.5P}{20+P}[/tex]
Multiply both sides by 20 + P
[tex](20+P)(3.20) = 71+2.5P[/tex]
Distribute the 3.20
[tex]64+3.2P = 71+2.5P[/tex]
Subtract 2.5 from both side and subtract 64 from both sides
[tex]0.7P = 7[/tex]
Divide both sides by 0.7
[tex]P = 10[/tex]
So 10 pounds will be needed

How to determine the card(B)?The set is given as:

Where
L = 9907
a = 1
d = 2

9907 = 1 + (n - 1)2
Subtract 1 from both sides
9906 = (n - 1)2

show the parabola please
The vertex of the given parabola is the point (3, 25).
How to get the vertex of the parabola?
If the parabola has roots x₁ and x₂, then the vertex of the parabola is at:
xₙ = (x₁ + x₂)/2
Here the parabola is:
y = (-2 - x)*(x - 8)
We can rewrite that to:
y = -(x + 2)*(x - 8)
Then the two roots are:
x = -2 and x = 8
Then the vertex is at:
xₙ = (8 - 2)/2 = 6/2 = 3
To get the y-value of the vertex, we evaluate the equation in x = 3:
y = -(3+ 2)*(3 - 8) = -5*(-5) = 25
The vertex is (3, 25).
