The original function is
f(x)=√x
As this is condition for √x function, x≥ 0
So,
Domain= [0, infinity)
Range= [0, infinity)
After the reflection across x-axis and y-axis, we get a function,
g(x)=-√-x
-x≥ 0 means x≤ 0,
So,
Domain= (-infinity, 0]
Range= (-infinity, 0]
From this you can see that
-The only value that is in the domains of both functions is 0.
-The range of g(x) is all values less than or equal to 0.
only these points are correct and all other points are wrong.
See the attached graphs for both functions.
Answer:
The probability that a student pick from this group at random either has blue or brown eyes is
P = 40/65 = 0.6154
P = 61.54%
Corrected question;
In a group of 65 students 10 have brown eyes and 30 have blue eyes. Find the Probability that a student pick from this group at random either has blue or brown eyes
Step-by-step explanation:
Given;
Total number of students = 65
Number of students with either blue or brown eyes;
= 10+30 = 40
The probability that a student pick from this group at random either has blue or brown eyes is
P = 40/65 = 0.6154
P = 61.54%
Mathematics is the queen of all science because every branch of science needs proof and we can prove it by mathematics. Mathematics is an essential component of the scientific method (data collection and observation and hypotheses are sustained by relevant mathematical models) , and mathematics is the language in which the Natural Physical World is written. Can anyone imagine physics without numbers , or without derivatives , integrals , equations , tensors , geometrical figures. Physics would be a barren field of study based

1. Postulates.
Postulates are some logical statements. They don't need proof. They are considered to be universal truth and they build the base of the proof of different theorems and formulae.
2. 33 units
AD is the sum of AB, BC and CD. It will be more clear from the photo attached above.
