Answer:
Sum of the number is 8.4
Step-by-step explanation:
x = sum of a number
(5 × x) + 6 =48
5x + 6 = 48
5x + (6 - 6) = (48 - 6)
5x = 42
5x ÷ 5 = 42 ÷ 5
x = 8.4
Answer:
15. It is a function
16. It is a function
Mapping diagram is attached for reference.
Step-by-step explanation:
Mapping diagram is a set of two parallel columns.
The first column includes the 'domain'.
And the second column includes the 'range'.
A relation is a function,
if every domain (
) has only one range (
)
The given coordinates in the set form are in the form (
)
15. We observe that each '
' is attached to only one '
'
Therefore this relation is a function.
16. We observe that here also each '
' is attached to only one '
'
Therefore this relation is also a function.
Answer:
(sin(t)+cos(t))^2=sin^2(t)+cos^2(t)+2sin(t)cos(t)=1+sin(2t)\\
