we can cancel terms
now, we can simplify it further
now, we can use trig identity
we can replace it
so,
Answer: Option 'B' and 'C' are correct.
Step-by-step explanation:
Since we know that irrational numbers are those real number which cannot be written in form.
Rational numbers are those real numbers which can be written in form.
Inverse property of multiplication is that property in which we write a number in reciprocal form .
Whole numbers starts from 0 and Natural numbers start from 1 and Integers contain both positive and negative numbers.
Hence, belongs to rational numbers sets and inverse property of multiplication sets.
Therefore, Option 'B' and 'C' are correct.
Answer:
Hence, the model that best represents the data is:
Step-by-step explanation:
We are given a table that shows the estimated number of lines of code written by computer programmers per hour when x people are working.
We are asked to find which model best represents the data?
So for finding this we will put the value of x in each of the functions and check which hold true that which gives the value of y i.e. f(x) as is given in the table:
We are given 4 functions as:
A)
B)
C)
D)
We make the table of these values at different values of x.
x A B C D
2 66.66 49.3 52.5 50
4 94.57 71.44 106.3 104
6 134.14 103.57 160.1 158
8 190.27 150.14 213.9 212
10 269.91 217.64 267.7 266
12 382.85 315.5 321.5 320.
Hence, the function that best represents the data is:
Option C.
y=26.9x-1.3
