Three types of numbers fall under the heading of "real numbers," which we will discuss in a moment. Real numbers include all types of numbers, including whole, rational, and irrational numbers.
What is Real number?A real number is a quantity that may be represented mathematically by an endless decimal expansion. In contrast to the counting-derived natural numbers 1, 2, 3,..., real numbers are used to quantify constantly altering quantities such as size and time. Rational and irrational numbers are both included in real numbers. Real numbers include both irrational and rational numbers such as 3, 22/7, and integers such as (-2, 0, 1), fractions such as (1/2), and decimal numbers such as (1/2).
whole = 0,1,2,3,4,5,6,7,8,9,10,11........….
rational = 12/23,3,3/4,5/6,...…
irrational = [tex]\sqrt{98}[/tex]

Solving the provided question, we can say that the equation we have here are y=-x+3 and y=3x-4 and y=x+2, so values of y are as => 0, 5 and 5.
What is equation?A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.
the equation we have here are
y=-x+3
y=3x-4
y=x+2
and the value of the x = 3
so values of y are as => 0, 5 and 5

Answer:
440miles
Step-by-step explanation:
She drove 11 miles to school and 11 miles back in the morning = 22 miles
She drove 11 miles to school and 11 miles back in the afternoon = 22 miles
Combined, the total for one day is 44.
For ten days, multiply 44 by ten to get 440 miles.
Why do ratios change?
Answer:
Generally, your current ratio shows the ability of your business to generate cash to meet its short-term obligations. A decline in this ratio can be attributable to an increase in short-term debt, a decrease in current assets, or a combination of both.
Sometimes, a low current ratio could suggest problems with inventory management, ineffective or lax standards for collecting receivables, or an excessive cash burn rate. Increases in the current ratio over time may indicate a company is "growing into" its capacity (while a decreasing ratio may indicate the opposite).

What percent of the shaded checker board squares do not have pieces?
VERY URGENT PLEASE
The 25% of the shaded checker board has pieces on it.
What percent of the shaded checker board squares do not have pieces?To check that, we need to solve the expression below:
Percent = 100%*(# shaded squares with pieces)/(total # of shaded squares)
There are a total of 32 shaded squares, and in 8 of them we can see pieces, then we can replace these values in the formula above to get:
Percent = 100%*(8/32) = 25%
That is the percent of the shaded checker that has pieces.

Mika rides his bike 3 miles each way to his friend's house. He leaves his house at 4 p.m. How many miles does he ride his bike there and back? What information is extra?
Answer:
How many miles does he ride his bike there and back?
6 miles.
What information is extra?
The hour at which he leaves his house.
Step-by-step explanation:
We know that he rides 3 miles each way.
Then he rides 3 miles from his house to his friend's house, and another 3 miles from his friend's house to his house.
So he rides 3 miles both times, if we add that, we get:
3 miles + 3 miles = 6 miles
So:
How many miles does he ride his bike there and back?
6 miles.
And to answer the other question, we need to look at the given information that we did not use in this calculation. In this case, is the hour at which he leaves his house.
Notice that we never did use the fact that he leaves his house at 4 p.m.
Then:
What information is extra?
The hour at which he leaves his house.

Answer:
AB = 42.30 m
Step-by-step explanation:
What we are asked to do is to simply find the length of AB.
Since both triangles are similar, therefore their corresponding sides would be proportional to each other.
Thus:
92/82.8 = 47/AB
Cross multiply
92*AB = 82.8*47
92*AB = 3,891.6
AB = 3,891.6/92
AB = 42.30 m(nearest hundredth)

Adigital option is one in which the payoff depends in a discontinuous way on the asset price. The simplest example is the cash-or-nothing option, in which the payoff to the holder at maturity T is X1{ST>K} where X is some prespecified cash sum. Suppose that an asset price evolves according to the binomial model in which, at each step, the asset price moves from its current value Sn to one of Snu and Snd. As usual, if T denotes the length of each time step, d < erT < u. Find the time zero price of the above option. You may leave your answer as a sum.
Answer:
[tex]V_{0} = e^{-rt}[/tex] ∑ [tex]uPdx^{(1-p)} *S_{o}[/tex]
Step-by-step explanation:
The Payoff to the holder at maturity T = X1{ST > K}, where X = pre-specified cash sum.
Current value of asset price = Sn after evolvement of asset price in reference to binomial model
Hence at every step value changes to SnU and Snd
where ; d < e^rΔT < u and Δ T = length of each step
u = ups
d = downs
Determine the time zero price of the above option
First we will find the price after each period
After one period :
when the price goes up, Sn + ΔT = Su
when the price goes down, Sn + ΔT = Sd
After period two
For Su
when price goes up, Sn +2ΔT = Su2
when price goes down, Sn +2ΔT = Sud
For Sd
when price goes down, Sn +2ΔT = Sd2
when price goes up, Sn +2ΔT = Sdu
To get the time zero price we will have to apply the same procedure in reverse position den get the sum pf all ups and downs which is
sum of all ups and downs = [tex]e^{-rT}[/tex]∑ [tex]uPd^{(1-p)}[/tex]
[tex]V_{0} = e^{-rt}[/tex] ∑ [tex]uPdx^{(1-p)} *S_{o}[/tex]

Write a fraction in which the numerator and denominator are both greater than 9.
btw im pretty sure that it has to be an improper fraction since it’s over 9 and 9 is a whole number.
Answer:
Step-by-step explanation:
It does not need to be an improper fraction.
For example, the numerator and denominator of 10/11 are both greater than 9, but 10/11 is not an improper fraction.
Answer:
Remember that a number divided by itself is 1. That means if the numerator and denominator are the same, the fraction is equal to 1. So all of the following are equal to 1: 2/2, 3/3, 4/4, and so on and so forth. so a good one you could do is 9/9

Breadth is 4cm
Step-by-step explanation:
Perimeter = 24cm
Length= 8cm
let the breadth be x
Perimeter = 2(l+b)
24 = 2(8+x)
24 = 16+2x
24-16 = 2x
8 = 2x
8÷2 = x
4 = x

Since, tigonometric identities are equal on both the sides (left hand side and right hand side) of the equation, Options (B), (C), and (D) represent the dientities.
Identification of the tigonometric identites: Trigonometric identities are the equalities having two trigonometric expressions equal for all values of the variables on both the sides.To prove the expression as identity prove both the sides of the equation are equal.
Option A
cos(x + y) + cos(x - y) = cos²2x - sin²2y
Left hand side = cos(x + y) + cos(x - y)
= cosx.cosy - sinx. siny + cosx.cosy + sinx.siny
= 2(cosx.cosy)
But the left side of the equation is (cos²2x - sin²2y).
Hence both the sides are not equal and it's not an identity.
OPtion (B).
sin(x - π) = -sinx
Left hand side = sin(x - π)
= -sinx sin(x - π)
= sinx.cosπ - cosx.sinπ
= -sinx - 0
= -sinx [Right hand side]
Since, both the sides are equal, it's an identity.
Option (C).
sin(x + y) - sin(x - y) = 2cosx.siny
Left hand side = sin(x + y) - sin(x - y)
= sinx.cosy + cosx.siny - sinx.cosy + cosx.siny
= 2cosx.siny
= Right hand side
Since, both the sides are equal, it's an identity.
Option (D).
cos(x + y) + cos(x - y) = 2cosx.cosy
Left hand side = cos(x + y) + cos(x - y)
= cosx.cosy - sinx.siny + cosx.cosy + sinx.siny = 2cosx.cosy
= Right hand side
Since, both the sides of the equation are are equal. It's an identity.
Therefore, Option (B), (C), (D) are the correct options.
