√7 is not a perfect square , so it's irrational
Answer is B. irrational numbers
P.S .
Keep in mind that any of non perfect square is irrational
Answer:
x^2 - 2x + 6
Explanation:
(x^2 + 1) - (2x - 5)
x^2 + 1 - 2x + 5
x^2 - 2x + 6
Given :
A clerk is paid $45.25 per hours for 40 hours a week, 1.50 times the regular rate of overtime and double the rate for a holiday.
To Find :
How much does the clerk get if he works overtime for 5 hours and 2 hours on holidays.
Solution :
Amount from regular job = $ 45.25 × 40 = $1810 .
Amount from overtime = $ (45.25×1.5) × 5 = $339.375 .
Amount from holiday = $ (45.25×2) × 5 = $452.5 .
Total amount clerk will get is :
T = $( 1810 + 339.375 + 452.5 )
T = $2601.875
Hence, this is the required solution.
Answer:
Step-by-step explanation:
diagram attached represents a function g(x).
Circle (1) (circle on the left) represents the set of domain (input values) and circle (2) represents the range (output values).
a). For input value x = 7, out put value of the function is y = 9.
Therefore, g(7) = 9 will be the answer.
b). Range of the function g(x) is the set of output values.
Range: {12, 9, 9, 17}
c). Inverse of the function g(x) will have,
Domain: {12, 9, 9, 17}
Range: {4, 7, 10, 15}
For input value of x = 9, there are two output values y = 7, 10.
Since, "a function can't have two output values for the same input value".
Therefore, inverse of the function g(x) will not represent a function.
