Answer:
The given relation 
is a function.
Step-by-step explanation:
A relation is given.
It is required to determine whether the given relation is a function.
To determine whether the given function is a relation, identify the domain and range and then check whether the given relation is a function.
Step 1 of 1
The given relation is {(a, b),(c, d),(e, d)}.
The set of the first components of each ordered pair is called the domain.
From the relation, the domain is {a, c, e}.
The set of the second components of each ordered the range.
From the relation, the range is {b, d, d}.
The given relation is a function. But it is not a one-to-one function.
Answer: 2.592 x 10^6 seconds
Explanation:
There are 3600s in 1 hr
And 24hrs in 1 day which mean
There are 3600 x 24 = 86400s in 1 day
And one month = 30 days
86400 x 30 = 2, 592, 000s in 1 month
Write in scientific notation:
2, 592, 000 = 2.592 x 10^6
The numbers inside the brackets determine which point lies on the line.
The general formula is
y - h = m(x - k)
The point that lies on the line however is (h,k) both turn to the opposite sign.
So in your case the point is (6,2). I have made a graph to show you that this is true. No other point is possible.
Answer:
x ≥ 88
Step-by-step explanation:
In order to have at least an average of 80 after 4 tests, the sum of her scores must be at least 80 * 4 = 320 so we can write the following inequality:
71 + 78 + 83 + x ≥ 320
232 + x ≥ 320
x ≥ 88
Answer:
from the given info
you can know that there were 16 red ones. (2/3)*24
and 8 green apples
and her classmates ate 3/4 of red ones i.e.
(3/4)*16
=12
and 1/2od green
i.e.
(1/2)*8
=4
and now the total eaten apples
= 12+4
=16
and the remaining number are
24-16
=8
