Answer:
(1) is a function, surjective aka onto,
not bijective aka one to one.
domain is {3,6,12,14,20,22},
range is {4,15,8,11}. More elements in domain means it can't possibly be one to one.
(2) is a relation but not a function, although its inverse is a function. There are fewer elements in the domain than the range, so a function could not be onto but would have to be into or injective.
The relation you get by restricting the domain to {1,19} is a function, injective, so that the image of the domain is a proper subset of the range.
Answer:
h*h=10*10+3*3
h*h=100+9
h*h=109
square root of h=square root of 109
h=10.44

The answer is option A
Step-by-step explanation:
Thirteen less than a number is written as
n - 13
Equate it to 42
We have
n - 13 = 42
Hope this helps you
In order to find the value first multiply both sides by 100 to simplify the equation:
0.05w*100=15*100
5w=1500
Next, divide both sides of the equation by 5:
5w/5=1500/5
w=300
The final solution is w=300!
Hope i could help.
